What is Vapour absorption machine?
It is a refrigeration unit based on Vapour Absorption Refrigeration Cycle (typically refrigerants used are Water or Ammonia).
Why COP is used for evaluation of compression refrigeration system but not absorption refrigeration system?
cause its a gas
What are the six states of a refrigerant in a refrigeration cycle?
what are the six states of a refrigerant in a refrigeration cycle
What is the purpose of refrigerant in air conditioning and refrigeration system?
used as cooling and freezing agent
What is meant by restricting liquid refrigerant into a refrigeration system when charging?
Vaporizing the refrigerant
R134a in refrigeration?
R134a is a refrigerant gas
How is liquid refrigerant added to the refrigeration system when the system is out of refrigeration?
Liquid refrigerant charging of a system is normally accomplished in the liquid line. For example, when a system is out of refrigerant, liquid refrigerant can be charged into the king valve on the liquid line or receiver.
When soldering a replacement fitting in a refrigeration circuit it is important that?
You take into consideration the type of refrigerant used in the system.
What are air conditioning and refrigeration reversible ratchet wrenches used for?
To open or close refrigerant service valves.
What is indirect refrigeration system?
Indirect and direct refrigeration systems are typically used on LPG carriers for cooling different cargos. Indirect systems cool the cargo by a refrigerant without being compressed. In the direct refrigeration cycle the cargo is compressed, condensed and returned to the tanks. The safer method is indirect refrigeration because the cargo never mixes with the refrigerant.
What is absorption refrigeration?
absorption refrigeration is when ice is put in a compartment above a warmer compartment and absorbs rising warm air thus making it colder.
Why is refrigerant vapor re introduced to the refrigeration system before refrigerant liquid?
To endure that the ONLY gas in the system is refrigerant.
