The process of refrigeration uses the vapor-compression refrigeration cycle to move heat from one place to another. In many HVAC air conditioning and heat pump applications the process of refrigeration or the vapor-compression cycle is what makes it work. This process, in the air conditioning mode, moves heat from inside the structure to the outside. Heat pumps draw heat from the outside even when it is cold and move the heat inside using the vapor-compression cycle or refrigeration. Heats pumps by the way, heat in the winter and cool in the summer but it uses the refrigeration process to accomplish the heating and cooling. The process of refrigeration or vapor-compression cycle in HVAC air conditioning and heat pump applications is a mechanical and chemical process of moving heat from one place where it is not wanted or needed and moving it to another place.
The Process of Vapor Compression Refrigeration
Vapor-Compression Refrigeration is the chief process used in residential and commercial refrigeration. This mechanical process is used by millions of people to stay cool by removing heat through vapor-compression refrigeration. The process of vapor compression refrigeration is also used in industry worldwide for warehouses, refrigerated trucks and rail cars, and other processes that need to provide cooling for industry. Vapor compression refrigeration typically involves a refrigerant which includes R-134A, R-22, and R-410A are the common types of refrigerants used in HVAC now. Vapor compression refrigeration uses compressors commonly used in HVAC such as the Reciprocating Compressor, the Rotary Screw Compressor, the Centrifugal Compressor, and Scroll Compressors as an essential part of the Vapor Compression Refrigeration process.
Moving Heat is Refrigeration
The HVAC air conditioning and heat pump refrigeration process is simply a matter of moving heat from one place to another. In moving this heat it either provides heating (for a heat pump in the winter) or provides cooling (for a heat pump and an air conditioner in the summer). There are many technical considerations for this process to work as efficiently as possible such as the proper amount of airflow or water flow across the evaporator and/or a properly charged HVAC air conditioning and heat pump system. For forced air systems a good tight ductwork system also helps efficiency as well as ensures that the conditioned air gets to its designated area. The process of refrigeration in HVAC works at maintaining comfortable temperatures for many different applications in HVAC.
