Understanding The Function Of A Cooling Tower In A Commercial AC System

Posted by on 11:45 am in Uncategorized | Comments Off on Understanding The Function Of A Cooling Tower In A Commercial AC System

A commercial air conditioner has to work hard to provide cooling to an entire building. In the process, the chiller system generates a large amount of heat itself–heat that has to be dispelled in some manner. If you would like to learn more about one of the most common strategies for dispersing the heat of a commercial air conditioner, read on. This article will provide a helpful overview of the component known as a cooling tower. The Basics The purpose of a cooling tower is to help return the heat generated by an air conditioner to the atmosphere by means of evaporation. While this may sound like a basic enough task, the fact is that it requires a large and fairly extensive system. At the heart of this system are two streams: one of water and one of air. As the stream of water circulates past the air conditioner, it absorbs heat. As the heated water moves through the system, it encounters relatively cool air, which takes on the heat through evaporation. As a result, the temperature of the water is lowered, thus allowing the process to be repeated. Benefits Of Evaporative Cooling The utilization of both water and air in an evaporative cooling tower is what makes cooling towers capable of safely dispersing such large amounts of heat. A “dry” cooling system like the radiator in a car, on the other hand, has much more defined limitations. In other words, evaporative cooling is able to do more work more quickly. Not only that, but it is also able to do so in a highly cost-effective manner. Direct And Indirect A particular evaporative cooling tower can fall into one of two main types: direct or indirect. Direct cooling towers, which are often also referred to as open circuit systems, allow the air stream and the water stream to directly contact each other. This interaction occurs in the part of the tower known as the fill–a labyrinth of open channels and tubes. Heated water is pumped to the top of the tower where gravity moves it downward through the fill. As it percolates back down, air moving upward absorbs its unwanted heat. Although the hot water is still pumped to the top and allowed to trickle downward, in an indirect cooling tower it never actually comes into contact with the air. In other words, they pass through the tower by means of two different circuits. The heated water moves through a system of interior passageways, while the air–often mixed with cool water–passes along an outer system. The heat transfer takes place indirectly, through the metal walls that separate these two system.

What To Know About Using Thermal Imaging To Detect HVAC Energy Loss

Posted by on 11:38 am in Uncategorized | Comments Off on What To Know About Using Thermal Imaging To Detect HVAC Energy Loss

Detecting areas where energy loss is occurring is perhaps the best way to lower the heating and cooling costs of a home or business. Thermal imaging is one of the best ways to accomplish this goal. If you would like to learn more about the role of thermal imaging in identifying HVAC losses, read on. This article will provide a helpful overview of this incredible technology. Some Basic Information Air leaks are responsible for the loss of approximately 1/3 of the energy that goes into heating and cooling a home. Historically, there weren’t many ways of addressing this problem aside from physically trying to feel out where drafts were occurring. As you can imagine, this method is only effective at eliminating the most glaring sources of energy loss. Fortunately, today it is possible to diagnose air leaks with a much greater degree of accuracy, thanks to the advent of thermal imaging technology. This technology uses infrared cameras to measure infrared radiation. In other words, you are able to view a color-coded image of the temperature gradients occurring inside of your home. This allows you to accurately identify not only air leaks, but also insulation voids, moisture penetration, and thermal bridges–all of which act to sap your home of its hot or cold air. When To Do Thermal Imaging When it comes to effectively thermal imaging a house, it is important to realize that the temperature outside plays a huge role. In relatively balmy weather, when the difference between the temperatures inside and outside of your home are fairly close, it will be much harder to detect areas of energy loss. That’s because the thermal image will all be roughly the same color. Thus it is best to inspect your home with an infrared camera during periods of more extreme weather, whether during the winter or the summer. The greater the gap between indoor and outdoor temperatures, the better results you will be able to get. Likewise, it is good to schedule the visit for the early morning, since this will reduce the blurring effect caused by the exterior of your home absorbing warmth from sunlight. Start On The Outside Beginning the inspection on the outside of your home is a good way to test whether conditions are appropriate for effective thermal imaging. The idea here is that you should be able to see vertical stripes along the walls and at the corners of your home. These correspond to the studs inside of the walls. Such studs allow a greater amount of heat to leak out than the insulation sitting adjacent to them. If you are unable to see the studs using your infrared camera, chances are the temperature outside is not drastic enough for proper thermal imaging.

Three Crucial Ways To Supplement Your AC’s Air Quality Features

Posted by on 7:01 am in Uncategorized | Comments Off on Three Crucial Ways To Supplement Your AC’s Air Quality Features

Although your AC unit can be great at reducing humidity and the vent filters help remove particles such as dust, mold spores, and other contaminants (especially if you use a high-quality filter at each vent), the system is primarily designed to control the climate of your home rather than keeping the air quality in line. Consequently, in some situations your home may require additional air quality mechanisms or systems for optimal air quality. Here are three essential ways to improve your air quality when the burden gets to be too much for the AC unit. 1. Humidifiers or dehumidifiers Humidifiers can be crucial if you live in a desert climate and don’t want dry, cracked skin. If, on the other hand, you live in a very humid climate, have poor drainage that makes for a damp basement, or have a recent mold problem and would like to prevent a reoccurrence by keeping your indoor air extra dry, dehumidifiers may be the solution for you. You can rent large, industrial-sized units for the most heavily affected areas, such as the basement, and you can get smaller, quieter units for the other rooms of the house. 2. Air cleaning systems An air purifying system can be essential if you have pets and pet allergies together in the same house or if you have lots of contaminants in the air for some reason (such as ongoing construction or home renovations, a recent mold infestation, or a family member with a bad case of dandruff). You can get either stand-alone units or systems that tap into the HVAC system, and various treatments that range from UV treatments to super-filtration are available to suit any need. 3. Plants Plants can help remove not only dust, mold spores, and pathogens from the air, but also VOCs (which are emitted from new products, cleaning chemicals, and more). Different plants have different strengths; for example, peace lilies like to suck up mold spores and aloe vera tends to trap a chemical called Benzene (one of the VOCs you can get from cleaning chemicals). You’ll need to have quite a lot of plants for maximum effect, however, so plan to have several large plants per room if you want them to help purify your air.  These three types of air quality boosters can help keep your air clean, modify the humidity according to your needs, and protect you from irritants such as mold spores and residue from cleaning chemicals.

About Getting Maintenance For A Gas Furnace

Posted by on 7:38 am in Uncategorized | Comments Off on About Getting Maintenance For A Gas Furnace

Do you find that you have to reignite your gas furnace pilot on a regular basis? Unless your furnace is old and damaged, the solution to the problem might be to invest in professional maintenance. It is actually in your best interest to get into the habit of making sure that your furnace receives periodic tune-ups. Professional maintenance can keep your heating system efficient and make the furnace more durable. In this article, you will learn about the areas of your gas furnace that will likely be examined when maintenance is performed. 1. Gas Line The gas line to your furnace is one of the most important parts that must receive maintenance because an explosion can occur if it is damaged. A contractor can make sure the line does not have any cracks in it that allow gas to leak out into your house. The fittings on the gas line will also be inspected in case they are loose or need to be replaced. A leaking line can cause a pilot to constantly go out due to it receiving only a small quantity of gas. 2. Pilot Orifice A contractor will inspect the pilot orifice to make sure it isn’t clogged up. Basically, the orifice is the area of the pilot in which the flame comes out. Dirt can create a blockage in the orifice that prevents a flame from igniting. Getting the orifice cleaned is the best way to make sure fire can come through it. 3. Gas Valve The gas valve is vital because it determines how much gas is released into the burner. During maintenance, the valve will be inspected to make sure it isn’t broken. A broken gas valve can easily be replaced by a contractor without you needing to replace the entire furnace. 4. Pilot Burner The pilot burner will be inspected to make sure it isn’t dirty. It is necessary for the burner to be cleaned every now and then so gas and fire can easily ignite a pilot flame. Rust is another thing that can lead to a pilot burner malfunctioning. It is possible that a replacement burner is needed if rust is present. 5. Thermocouple A thermocouple is a part that must be in good shape in order for a pilot to remain ignited. The gas valve must receive a signal that the pilot is ignited in order to release continuously gas, which is the job of the thermocouple. A contractor will inspect the thermocouple to make sure it isn’t damaged.  Reserve a date for a contractor to perform maintenance on your gas furnace. You can learn more about furnace maintenance services by checking out a site like...

3 Ways To Avoid An Air Conditioner Repair

Posted by on 7:59 am in Uncategorized | Comments Off on 3 Ways To Avoid An Air Conditioner Repair

Being able to remain cool in summer can be a real challenge. Usually, the most efficient way for you to do so is by working to properly maintain your AC unit, reducing the possibility of expensive repairs. By knowing some of the things you can do that will help keep your air conditioning in good working order, these can be helpful for you. Remove debris One of the first things you will want to do is to take just a few minutes and clean your outside unit. You should look for any debris around the unit and remove these things. For instance, during the fall months, you may have leaves that clutter around your air conditioning unit and may prevent it from functioning properly. On the other hand, when the weather is warmer, you may have weeds and grass that gets high that should be trimmed. Be sure to keep your unit as clean as possible and even unscrew the fasteners and get rid of debris on the inside of the unit occasionally to keep it running smoothly. Clean the evaporator coil It’s ideal to keep the key components of your unit as clean as possible, and one of these is the evaporator coil. This item is usually located on the inside blower door. You will want to keep the evaporator coil clean to prevent the need for any repairs at a later date. You can use a soft brush to clean the coil itself, and this will remove dust and debris that may have built up on it. Clean the drain pan One part of your air conditioning unit you will want to keep clean is the drain pan. This can become full of water from your unit over time, and it’s ideal to prevent this from overflowing and to do a thorough cleaning of this pan. Most experts agree that a mixture of 50% water and 50% bleach poured down the drain will up prevent any clogs and maintain the cleanliness in this area. Being able to avoid expensive air conditioner repairs is ideal and will take some work and effort on your part. It’s important to understand what maintenance to do in order to get the best results. However, if you are faced with an air conditioner that quits working, be sure to give your HVAC contractor, like those at Absolute Air Conditioning & Heating, a call...

Summer Is Coming: 3 Steps To Safely Put Your Heater To Bed Till Winter

Posted by on 7:59 am in Uncategorized | Comments Off on Summer Is Coming: 3 Steps To Safely Put Your Heater To Bed Till Winter

When the weather starts to turn warm, your mind automatically turns to your air conditioner. Not so fast, though. Before you switch your air conditioner on this summer, you should make sure that you bid a proper farewell to your heater. You may think that simply turning it off for the summer is good enough. Unfortunately, that could leave you with a rude awakening next winter. Here are four steps you should take to put your heater to bed for the summer. Clean the Motor and Fan While your heater was busy keeping warm during the winter, it was collecting dirt and dust. Those contaminants built up on the motor and fan. Unfortunately, if those contaminants remain on your heating unit during the summer, they can cause serious damage to your heating components. To get your motor and fan ready for summer, you’ll need to grab a shop vacuum. Begin by removing all the dirt and dust from around the motor housing. Once you have that area clean, move on to the fan. Be sure to clean each blade. Check for Safety Issues Once you’ve cleaned the motor and fan, you’ll want to inspect your heater for safety issues. Some of the safety issues you should look for include the following areas. Leaks in the gas lines. Holes in the furnace fire box Scorch marks around the thermocouple or ignitor switch. If you notice any of the problems mentioned above, you should notify your heater technician as soon as possible. You’ll need to have those issues repaired before you turn your heater on next winter. Change the Filter You might think that the filter won’t affect your heater since it won’t be operational during the summer. Unfortunately, that’s not correct. Using your air conditioner with a dirty filter will still deposit dirt on your heater, since the ducts in your home filter through both systems. Before you shut your heater down for the summer, be sure you replace the filter. This will ensure that both your heater and your air conditioner are protected during the summer. A good rule of thumb is to change the filter at the start of each new season. This will ensure that you switch your filter at least four times each year. Now that it’s time to put your heater to bed for the summer, you want to make sure you do it properly. For more information, contact D & W Heating & Air Conditioning Inc. or a similar...

Two Tips To Keep In Mind When Getting A New HVAC System Installed

Posted by on 11:39 am in Uncategorized | Comments Off on Two Tips To Keep In Mind When Getting A New HVAC System Installed

Whether you’re moving into a new home and getting the heating, air conditioning and ventilation (HVAC) system installed, or you’re replacing the unit you have in your current abode, you want the work to be done with quality and expertise.  Depending upon the square footage of your home, you can pay upwards of $12,000 dollars for a new HVAC system, a sizable sum that you want to invest in the right company.  When you’re getting a new HVAC system installed, use these tips to ensure that the job is done right. Pay Attention To The Warranty If you’ve already consulted with an HVAC installation contractor who told you that there is a warranty available, you may believe that you’ve found the perfect person.  However, it’s important to pay attention to the kind of warranty being offered, because there are differences. There are typically two different kinds of warranties:  The manufacturer’s version and the contractor’s version.  The manufacturer’s warranty is usually going to strictly cover the parts themselves, so that if one or more of the components on your HVAC system starts to malfunction, they can be replaced.  If this is the only kind of warranty being offered, there could be a problem. You need a worker that also offers a contractor’s warranty.  This one will cover the labor.  So, if the contractor happens to install one of the parts incorrectly, they will come back out within a stated period of time to make the appropriate changes.  This is important, because some manufacturer’s warranties will not cover parts that were not installed according to company specifications. Insulation Should Go Hand-In-Hand With Your HVAC System Another consideration you should make when you’re getting a new HVAC system installed is the effectiveness of your home’s insulation.  Failing to make sure that you have a sufficient amount of insulation in your home is almost equivalent to letting money slip right through your fingers. It doesn’t matter how much money you invest in that top of the line, energy efficient HVAC system if your home has poor insulation.  More of your indoor air will seep outside, causing your system to have to work that much harder to maintain the intended indoor climate. When you’re getting your new HVAC system, take the time to call in an insulation professional as well.  They can check the walls, attic and even the basement of your home to make sure that they are properly insulated. Getting a new HVAC system doesn’t have to be a stressful process if you know what to do.  The next time you’re getting one installed, keep these tips in mind so you can have a satisfactory...

What You Should Know About Maintaining Your HVAC System

Posted by on 9:58 am in Uncategorized | Comments Off on What You Should Know About Maintaining Your HVAC System

When you purchase your first house, you may find yourself unsure about a great deal of the maintenance tasks that you need to perform. As a previous renter, you had a landlord and a maintenance service that helped you whenever you needed heating and cooling services or had plumbing or other issues. Now, your HVAC system is entirely your responsibility, and you may not know what steps to take to keep your heating and cooling systems running as smoothly as possible for as long as possible. Get to know some of these steps to take and get started as soon as possible. Have Your Heating and Cooling Systems Professionally Inspected Annually One of the best ways that you can be sure that your heating and cooling systems are functioning as well as possible is to have an HVAC professional inspect your systems regularly. It is best to have two appointments a year. Have your furnace and heating ducts inspected in the fall and your air conditioning unit both outdoors and indoors inspected in the spring. These inspections will ensure that your systems are clean and in good working order before they need to be used on a regular basis. Change Your Air Filters Seasonally or Monthly Because your heating and cooling systems are largely responsible for the quality of the air that is circulating throughout your home, you need to be sure that that air is as clean and free of contaminants as possible. To make this happen, you need to frequently check and change your system air filters. Generally speaking, your air filters will need to be changed seasonally at the very least. However, many HVAC specialists recommend that you change your filters once a month or once every couple of months. In addition to changing your air filters frequently, you may also want to purchase a high-efficiency air filter that is designed to trap allergens and other particles. While these air filters are a bit more expensive than standard filters, they provide you with the best possible air quality. With these tips in mind, you can better maintain and care for your heating and cooling systems in your new home. With professional assistance and regular filter changes, you can keep your system running as smoothly as possible. You will also want to be sure that you keep the areas around your HVAC systems clean and clear of debris so that you can easily access them for repairs and maintenance.

3 Tips To Keep Your Home Allergen-Free This Fall

Posted by on 5:57 am in Uncategorized | Comments Off on 3 Tips To Keep Your Home Allergen-Free This Fall

If you are like many people, you might suffer from fall allergies as the temperatures start to cool down. Although you might enjoy the cooler temperatures and the pretty colors of fall, you might not enjoy the discomforts of your allergies. One great way to combat your fall allergies is by keeping your home as allergen-free as possible. Luckily, doing so is easier than you might think. These are a few things that you can do to improve your indoor air quality during the autumn and prevent allergy symptoms among you and your family members. 1. Keep Walking Surfaces Raked and Cleaned Even though you might love how the fall leaves look in your yard, it’s best to keep them cleared away from your walking surfaces. Take the time to rake, sweep or blow away leaves that might linger on your porch, driveway, walkway and other walking areas. This will help prevent allergens from sticking to your shoes and your pants when you walk in the door. 2. Set Up an Outdoor Rug Keep a nice outdoor rug by your front and back doors. Make sure that you keep them outdoors rather than inside; then, when you wipe your feet off to get rid of any potential allergens, you won’t have to worry about them being inside of your home. 3. Take Good Care of Your Heating and Air Conditioning System During the fall months, it isn’t uncommon to run your heater and your air conditioner at different times throughout the week. Make sure that both are in good condition and that your air filters are changed regularly. It’s a good idea to have an HVAC professional from a company like Bill’s Heating & Air Conditioning come out and take a look at your HVAC system in the fall anyway; then, not only can you ensure that your system is filtering the air in your home properly, but you can also ensure that your heater is in good condition and is ready to keep your home warm and toasty this winter. Also, changing your air filters a little more frequently — and using a filter that is designed to help trap home allergens — can be a good idea if you want to keep home allergens to a minimum this fall. The last thing that you probably want to deal with in your home this fall season is allergy symptoms. Luckily, if you follow these three tips, you can help keep your home...

3 Ways To Reduce Issues With Cold-Weather Condensation In Your Home

Posted by on 8:43 am in Uncategorized | Comments Off on 3 Ways To Reduce Issues With Cold-Weather Condensation In Your Home

When the cold weather sits outside your home, you will be firing up your home heating system and enjoying the warmth that it provides. However, if you have issues with cold-weather condensation, there is a pretty good chance you will unfortunately be dealing with moisture problems on your walls and windows. To eliminate issues with cold-weather condensation, you have to understand what the problem is, where it comes from, and why it is an issue in your home.  So, where does cold-weather condensation come from? If you live in an area where the temperatures dip well below freezing, the internal temperature of your home will not fare will against cold that is seeping in through the walls of your house. This interaction will actually cause the walls to sweat condensation, which can drive humidity levels higher and even cause issues with water damage. In most cases, this is a sign of a home that is not well insulated. However, you might only see small spots affected by condensation where there is not enough insulation, such as around electrical fixtures or plug-ins. Insulation prevents the different air temperatures from coming in contact with each other, which will prevent condensation from forming.  What is the easiest way to eliminate the problem with condensation in your home? To get rid of excess condensation, it is best to have a professional come in and make sure your home is appropriately insulated. If the insulation is not the issue, your home heating system may need to be fitted with a dehumidifier unit that traps moisture in the return ventilation and eliminates it from the air in the house. This will dramatically reduce the amount of moisture in the air and keep condensation at bay.  Why is condensation more of an issue in upper levels of the house? The upper levels of your home are often more prone to condensation because they may be more exposed to colder temperatures in the atmosphere outside. If your home has an outdated heating system, heat may also be less likely to be distributed appropriately throughout the home, which will cause warm air to rise to higher levels of the house.  Even if your home heating system is working well, if you have issues with cold-weather condensation in the winter months, it is best to have a professional HVAC expert, such as Avery Heating & Air Conditioning, come out and take a look. The longer you deal with the issue in your home, the more your house will be susceptible to water...
