The Principles of Commercial Chillers

Wednesday, August 27th, 2014

If your large commercial property has unique cooling needs, a commercial chiller may be the right system for your building. Commercial chillers provide excellent and efficient space conditioning throughout a large space, but they may also be used for a variety of industrial process cooling needs. This may include cooling requirements for laboratory equipment, hospital equipment, or factory machinery. There exist many different types of chillers that can be used for a range of purposes, so it will be difficult to select the right type on your own. To choose the correct kind of chiller for your building in Avon Lake, you’ll want to talk to the experts at Westland Heating and Air Conditioning. For now, let’s take a brief look at how these systems operate and how you should maintain your unit.

How Chillers Work

Chillers rely on a vapor-compression cycle to remove heat. A liquid is chilled as it continuously cycles through the system. While this liquid is usually purely water, water may be combined with glycol or propylene as well. First, the water absorbs heat at the evaporator. Then, the compressor allows water to release heat into the outside air. In most commercial applications in the U.S., a type of mechanical compressor is used, in which the refrigeration process lowers the temperature, but other chillers may rely on air cooling or water cooling to remove heat. In any case, chilled water is stored in a reservoir and a pump circulates water to the building or to the area requiring cooling. The liquid is then pumped back to the evaporator to begin the process again.

Chiller Maintenance

Cooling a large space uses a lot of energy, so it’s important to keep your system efficient by scheduling regular maintenance for your chiller and calling a technician at the very first sign of a problem. Listen for strange noises, check for leaks, pay attention to temperature settings, and call a professional technician twice a year for a professional cleaning and inspection.

Ways to Keep Your Air Conditioning Bills Down

Wednesday, August 20th, 2014

Your air conditioner works hard to cool down your entire home, so it’s no wonder the AC consumes a lot of energy. But by the end of summer, many homeowners will try anything they can to save a little bit on cooling costs. Of course, you can save money by shutting off your air conditioner. But on a hot day, isn’t there some other way to beat the heat and keep costs low? Here at Westland, we want to help you save some money, so we’ve put together a guide to a few of the ways you can lower your air conditioning bills.

Change or Replace Air Filters

The filter in your air conditioner helps improve the air quality in your home. Most manufacturers recommend replacing or cleaning the air filter once a month, but this isn’t only to keep the air clean. A clogged air filter can significantly decrease the efficiency of your air conditioner, reducing the fan’s ability to suck in the air from your home in order to remove heat.

Keep Outside Unit Free of Debris

The outside portion of your air conditioner contains a large fan that sucks in the outside air to help refrigerant with the condensation process and help heat to dissipate into the air. If clutter or vegetation blocks the outdoor unit in any way, it may become impaired or unable to complete the refrigeration process effectively and efficiently. Clear away large debris from the unit and listen for unusual noises, such as a banging noise, that may indicate debris is stuck in the unit. Call for repairs at the first sign of damage.

Schedule Regular Maintenance

One of the most beneficial things you can do for your air conditioning system is scheduling regular maintenance with an air conditioning technician. Maintenance is an important service in which a technician inspects, cleans and adjusts various parts of your system. It’s important to catch repair needs early on to prevent the possibility of sudden breakdowns and to lessen the impact of wear and tear on your system.

How Heat Pump Repair Differs from Air Conditioning Repair

Friday, August 15th, 2014

There’s a lot of confusion about how heat pumps differ from air conditioning systems. The truth is that a heat pump in cooling mode is an air conditioner. The main difference is that a heat pump can also heat, due to its reversing valve. So, when it comes to heat pump repair versus air conditioning repair in Avon, there are only a couple of key differences between the two. For over 25 years, Westland Heating and Air Conditioning has helped customers with both heat pump and air conditioner repair, and we can help you, too.

Differences Between Heat Pumps and ACs

The best way to answer the question about repair differences is to first look at the comparative components of a heat pump and an air conditioning system. Both have a compressor, a condenser and an evaporator. Both use fans and refrigerant. The main difference, as mentioned above, is that a heat pump has a component called a reversing valve that allows the heat pump to both cool and heat by reversing the flow of refrigerant; a second difference is that a heat pump’s mode of operation is reverse refrigeration, whereas an air conditioner’s is a vapor compression cycle.

Heat Pump Reversing Valve

The reversing valve resides inside the heat pump. The valve is attached to a small solenoid that supplies low-voltage electricity to it that is necessary for making the switch between heating and cooling. Common problems that can occur with the valve are:

  • The valve gets stuck
  • The solenoid goes bad
  • A refrigerant leak develops in the valve

Sometimes a stuck valve can be repaired, but sometimes it needs to be replaced. A solenoid can be repaired, rather than replacement, unless the solenoid is no longer available. Refrigerant leaks can be repaired, and should be repaired by a trained professional.

Year-Round Operation of Heat Pump

Air conditioners run only during the warm months of the year, whereas a heat pump will run year-round. As such, normal wear-and-tear for heat pumps is higher, so there is more likely to be a need for repairs on a heat pump versus an air conditioner. Additionally, it is important to keep up with bi-annual maintenance on heat pumps due to the year-round operation.

Use a Professional for Both

Whether you need heat pump or air conditioning repair in Avon, it’s important to always use a trained professional. Call Westland Heating and Air Conditioning today and schedule an appointment with one of our trained technicians.

What Size Pool Heater Do I Need?

Friday, August 8th, 2014

A quality pool heater, properly sized, is essential if you want to receive the most use from your home’s pool. You can enjoy your pool during more months of the year outside of summer thanks to an effective pool heater keeping the water warm and pleasurable. If you have a pool, or are planning to construct one, you should arrange for installation of a pool heater.

However, a heater that’s the wrong size for a pool will cause problems. How can you know the correct size of heater? The easiest way is to contact professional installers, like those at Westland Heating and Air Conditioning. We’ve had extensive experience with sizing and installing pool heaters in Westlake, OH during the more the 25 years we have been in business. Call us today to set up an appointment for finding the right pool heater for your comfort. We will handle installation and the necessary maintenance as well.

Determining Pool Heater Size

Although you should leave the actual job of sizing a pool heater to trained professionals, we can give you a quick tour through the factors used in finding out the right size of heater.

One of the first things to know about sizing a pool heater is that water volume isn’t the essential aspect of determining how powerful the heater should be. A pool heater takes on the job of replacing the heat that the pool loses across its surface, so surface area is the most important specification to know about a pool.

The installers first take the average pool temperature you wish for comfort. They then determine the average temperature of the coldest month when you plan to use the pool, and subtract this temperature from the target temperature. This number is the temperature increase at its greatest that the pool needs.

Next, the installers calculate the surface area of the water in the pool in square feet, and use this formula to find out how many BTUs (British Thermal Units) per hour a pool heater must generate to reach the temperature increase: pool area X temperature increase X 12. The last multiplier is based on average heat loss considering wind speed and the rate of outdoor temperature increase, and the installers will adjust the multiplier according to your local conditions.

With the right installers with experience sizing pool heaters in Westlake, OH on the job, you will receive a system with the right BTUs per hour to keep your pool comfortable late into the season. Westland Heating and Air Conditioning has a team to handle this job, one familiar with local weather conditions that will factor into the calculations.
