If you manage a building with a large HVAC system, you will need to maintain the unit so that you will be able to keep your building cool and comfortable. One of the most important parts your HVAC system uses is the compressor. This part might be something you can remove and replace or might be part of a packaged system.
Packaged HVAC Systems
If your HVAC unit is a packaged system, it will come with a compressor, condenser, evaporator coil, and fan coil. They are often used in hotels and senior homes because the resident can adjust the temperature manually.
VRF Systems
VRF systems are newer HVAC systems that do not use ducts. An outdoor unit stores all of the compressors and condensers. These units send refrigerant to the building which is used to pump heat into the building or to pump heat out of the building depending on whether you are increasing or decreasing the temperature of your commercial building.
Power and Energy-Efficiency
One of the challenges of a commercial HVAC system is that it is much larger to be able to heat and cool a building. This means that the compressor must also be much more powerful to be up for the task.
Your HVAC unit is also likely to be one of the most energy-hungry units in your building. Therefore, you'll want to make sure that your AC is able to cool the building in the most efficient manner possible. Some compressors are more efficient than others and the most efficient are centrifugal compressors and rotary screw compressors. The scroll compressor in particular can be very clean because you have the option of an oil-free model.
Reciprocating Compressors
The reciprocating compressor is the oldest type of commercial compressor. It uses mechanical energy generated from pistons to increase pressure so that you can compress the gas in your HVAC system. The power of this type of compressor depends on how many pistons it uses with the most powerful compressors using as many as half a dozen.
Screw and Scroll Compressors
One of the primary advantages of reciprocating compressors is that they are inexpensive. However, if you are willing to spend more money, a screw compressor or a scroll compressor can be much more efficient. They operate smoothly and quietly. They are less likely to wear out as quickly because of their superior design. Once you know exactly what your business needs, you'll be able to find the right compressor.
