HVAC systems perform heating and cooling for residential and commercial buildings. They are also sometimes used to pull in fresh air as a way to dilute contaminants in the air. These contaminants can be odors, organic compounds, chemicals, or other items. When properly maintained, these systems create a comfortable environment in any building where they are used. Many commercial businesses use HVAC systems that have been installed by an industrial air conditioning service because they are reliable and efficient. When installed by a professional, they can reduce energy costs for a company. There are many types of commercial HVAC units available for both residential and commercial use.
A cooling only split-system consists of two pieces. The indoor unit contains the supply fan, cooling coil, and an expansion device. It handles air flow throughout the building. A condensing unit is located outside. The condensing unit houses the compressor and the condenser coil. These systems are often found in homes and small commercial buildings. They have one of the highest energy efficiency ratings of all types of air units. Another form of heating must be used with a split-system such as electric heating.
A cooling only packaged-system has all components of the split system, but in one casing. It is placed on the outside of the building. Air is sent to the system through air ducts and then sent back as cool air by a distribution system. They also require a separate heating method just as the split-system.
Another form of HVAC for commercial buildings is the heat pump. They are much like a cooling only system but have the ability to reverse the refrigeration cycle. This type of system can cool and heat indoor air. Sometimes an electric resistance heater can be used to help at lower temperatures. Heat pump systems need a period of time to defrost in colder temperatures. The electric heater must be used to heat the building while the pump is defrosting. Heat pump units are sold as both split and packaged units.
Another option when it comes to HVAC for commercial buildings is a chilled water system. These types of commercial HVAC systems have water pumped all through the building. Water coils cool the water. A cooling plant or chiller plant must be used to transform cold water to cool air. This transition is performed by special heat exchangers located in various spots of the building.
The most commonly used type of air conditioners is the split or package cooling only units. These are fairly easy to install and do not require special equipment or facilities to run. With the proper maintenance, cooling only systems remain efficient and effective for many years. Contact an industrial air conditioning service to determine the type and size of system that will work best for your business facilities. They can give you an estimate based on your needs and general installation costs. Once the system is installed, be sure to have them perform maintenance on it every year to ensure the air unit has a long and productive life.
