How Central Air Conditioning Cools Large Homes or Offices
Every year as summer sets in and the temperatures start to rise, people are reminded about how terribly uncomfortable the temperatures can get inside of homes and offices that are not air conditioned. Usually, when the weather heats up there is a rush of people searching for ways to stay cool and comfortable. Many people look to central air conditioning to make their homes or offices a place where it is possible to comfortably work, play, relax and sleep. These centralized systems are ideal for cooling large spaces where a room air conditioner is just not enough to do the job.
“Split systems” are able to condense and compress the air and this is why the central air conditioningsystem is so effective. Additionally, these systems use an evaporator that is connected to the mechanism that handles air, such as a forced-air furnace. Once the whole unit is assembled it is installed outside, either on the roof of a commercial building, or a unit outside of a home.
When central air conditioning begins functioning, the cooled air is blown through the edifice by fans via the ductwork that has been installed, allowing the air to flow to the different areas in the building. The temperatures are controlled either with the use of a central control unit, several units to control different zones, or individual control units that are placed in each room.
Unfortunately, some of the centralized air conditioning systems are not equipped with these controls. In these cases, you will need to purchase the controls for additional cost, and they should be installed at the same time as the entire unit. It is important to clarify this upfront with company that is selling and installing the unit so that there are no surprises during the installation process.
Since the noise associated with keeping the home cool is located outside, most homeowners prefer central air conditioning systems. Today, room air conditioners are noisy, and this is especially noticeable if you are trying to sleep. Central air systems position the equipment that is responsible for the majority of the noise on the outside of the house. Eventhough the air conditioning unit may be working hard to keep the home cool, the interior of the home is nice and quiet.
Central air conditioning systems are rather complex and are usually installed when a building is under construction. To have a comfortable and healthy environment in a home or office, these heating and air conditioning systems supply the air filters and purifiers as well as heating and cooling. In order to properly circulate the air, centralized systems us supply and return ducts placed throughout the structure.
When you replace and existing air conditioning system or when purchasing a new one, have the contractor perform a “cooling load calculation” to ensure the correct system is installed. To avoid having oversized equipment, use something besides the “rule of thumb”. A newer unit of the same size shouldn’t just replace the old system. The reason for this is because the existing system may have been the wrong size to begin with, or the home may have had added insulation or more efficient windows put in since the original system was installed.
Air conditioning manufacturers are required to get their equipment tested for how energy efficient it is and it is then given a rating. This is a requirement under federal law. Central air conditioning is given a SEER rating, which stands for Seasonal Energy Efficiency, while heat pumps carry a HSPF rating, referring to Heating Seasonal Performance Factor. Look for models with the highest SEER or HSPF rating, which means they are most efficient.
