Refrigeration and Air Conditioning Practice Test: Refrigerant Compressors — Flashcards

Refrigerant Compressors topics include: Multi stage compression, refrigerant compressors and its types.

Refrigerant compressors are used to compress refrigerant gas in refrigerators and freezers. When choosing a refrigeration compressor, you can consider things like: Capacity, Condensing temperature, Evaporating temperature, Flow rate, Power. 

Other features to consider include: Thermal shut off, Sealing, Low noise, Light weight, Variable speed. 

Here are some types of refrigerant compressors:
Danfoss refrigeration compressors: These compressors are designed for light commercial applications and are UL certified. They can be used with refrigerants R134a, R404A/R507A, R407C, R290, and R600a.
Hermetic compressors: These compressors are a type of positive displacement compressor where the motor and mechanical systems are enclosed in a single unit. They are primarily used in refrigeration systems.
Rotary refrigeration compressors: These compressors use a rotor to compress refrigerant gas. They are commonly used in small to medium-sized air conditioning and refrigeration systems.
Scroll compressors: These compressors are a type of reciprocating piston compressor that vaporizes and compresses fluid refrigerant in an ever-upward spiral movement. They are more efficient than other types of compressors and require less power to operate.
