What are the four stages of refrigeration?
The compressor, condenser, expansion valve, and throttle valve are part of the Vapor Compression Refrigeration Cycle. The aim of the compression process is to raise the pressure in the air.
Why is it called an air conditioner?
The term air conditioning was borrowed from the textile industry, where it referred to filtering and dehumidifying. The first use of this term is in a 1909 paper by Stuart Cramer, called “Recent Developments in Air Conditioning.” This is part of a complete episode.
How much is a ton of refrigeration?
A refrigeration ton is approximately equivalent to 12,000 BTU/h or 3.5 kW. Air-conditioning and refrigeration equipment capacity in the U.S. is often specified in “tons” (of refrigeration).
Why is wet compression not preferred?
Wet compression is undesirable as there may be accumulation of liquid inside the cylinder, which in turn will wash away the lubricant resulting in severe mechanical difficulties. Thus, to avoid this, a 5 to 20 K superheat of the refrigerant is always desirable.
