An example of an HCFC refrigerant is?
R22 r123
How do you change high temperature refrigerant and high pressure refrigerant in to low temperature refrigerant and low pressure refrigerant?
You cool it and run it through a metering devise.
Which refrigerant is considered high or very high pressure refrigerant?
r 134-a
What happens when refrigerant enters the condenser?
what happens when refrigerant enters the condenser
Does refrigerant exit the compressor as a high temperature high pressure liquid?
No , a high temperature high pressure ( gas )
What does the condenser do in a refrigeration or air conditioning system?
It passes heat out of the high pressure high temp vaporized refrigerant so the it becomes a high pressure lower temperature liquid.It passes heat out of the high pressure high temp vaporized refrigerant so the it becomes a high pressure lower temperature liquid.
What does AC compressor do?
Cycles refrigerant through the system and changes the state of the refrigerant from a low pressure vapor to a high pressure vapor.
What is a brief description of the basic refrigeration cycle?
Starting at the compressor;Low pressure vapor refrigerant is compressed and discharged out of the compressor.The refrigerant at this point is a high temperature, high pressure, superheated vapor.The high pressure refrigerant flows to the condenser by way of the "Discharge Line".The condenser changes the high pressure refrigerant from a high temperature vapor to a low temperature liquid and leaves through the "Liquid Line".The high pressure refrigerant then flows through a filter dryer to the Thermal Expansion valve or TXV.The TXV meters the correct amount of liquid refrigerant into the evaporator.As the TXV meters the refrigerant, the high pressure liquid changes to a low pressure, low temperature, saturated vapor.This saturated vapor enters the evaporator and is changed to a low pressure dry vapor.The low pressure dry vapor is then returned to the compressor in the "Suction line".The cycle then starts over.
What is the normal pressure high and low for a roof top unit?
The refrigerant pressures are dependent on the type of refrigerant.
Is refrigerant leaving a compressor in a cars air conditioning system high pressure vapor high pressure liquid or low pressure vapor?
high pressure vapor
How is the refrigerant cylinder pressure kept above the system pressure when a system is being charged with vapor from the cylinder?
Add refrigerant vapor on the low side of the system ,the compressor raises the pressure of the refrigerant on the high side of the system and lowers the pressure on the low side
