What does the evaporator do in a refrigeration system?
The evaporator works the opposite of the condenser, here refrigerant liquid is converted to gas, absorbing heat from the air in the compartment. When the liquid refrigerant reaches the evaporator its pressure has been reduced, dissipating its heat content and making it much cooler than the fan air flowing around it.
Which of the following can result from evaporator freeze up?
Which of the following can result from evaporator freeze-up? The refrigerant may not properly evaporate, Air is not drawn over the fins, & The air-conditioning system produces little or no cooling.
What are the conditions required for an ideal evaporator?
Between 16 °C and 27 °C. The evaporator target temperature is progressively increased while maintaining a low enough temperature to prevent misting. Typically between 20 °C and 30 °C the customer requested discharge temperature for comfort becomes lower than that calculated to prevent misting.
What connects the evaporator to the compressor?
Suction line
What is the unit of refrigeration?
A ton of refrigeration (TR), also called a refrigeration ton (RT), is a unit of power used to describe the heat-extraction capacity of refrigeration and air conditioning equipment. It is defined as the rate of heat transfer that results in the melting of 1 short ton of pure ice at 0 °C (32 °F) in 24 hours.
How many kW is 1 ton?
3.517 kW
How many CFM’s are in a ton?
400 CFM
Is a higher or lower cop better?
Higher COPs equate to lower operating costs. The COP usually exceeds 1, especially in heat pumps, because, instead of just converting work to heat (which, if 100% efficient, would be a COP of 1), it pumps additional heat from a heat source to where the heat is required.
What does copping mean?
copped; copping. Definition of cop (Entry 2 of 4) transitive verb. 1 slang : to get hold of : catch, capture also : purchase. 2 slang : steal, swipe.
What does the 5 0 mean?
