Can you mix R401a and R409a?
No. You absolutely cannot mix any refrigerants. You should completely recover all the old refrigerant and charge the system, with the new refrigerant, using the superheat method.
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.
What refrigerant is a low pressure refrigerant under EPA's refrigerant recycling regulations?
R22
What refrigerant is considered a low-pressure refrigerant under EPA's refrigerant recycling regulations?
R22
What happens when refrigerant enters the condenser?
what happens when refrigerant enters the condenser
The function of the condenser is too increase refrigeration pressure lose the heat from the refrigerant add heat to the refrigerant reduce the fridge aration pressure?
lose the heat from the refrigerant
When charging a system with vapor refrigerant from a refrigerant cylinder the cylinder will become?
Lighter, as the refrigerant is boiled off, and colder, as it has absorbed heat, and has a lesser pressure to reflect the current temperature / pressure relationship for the type of refrigerant
What is a low pressure refrigerant under EPA's refrigerant recycling regulations?
R22
Which refrigerant is considered high or very high pressure refrigerant?
r 134-a
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
How is the refrigerant cylinder pressure kept above the system pressure when a system is being charged with the vapor from a 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
