What is the internal pressure of a cylinder with one ounce of liquid R410A refrigerant which has been sitting in a 100 degree Fahrenheit truck?
?
What are the correct pressures for R410a?
The pressure for an R410a air conditioner system should be 118psi LP and 412psi HP. This is the same pressure as an R22 air conditioner.
Can you use a r410a condenser brand new with a r22 air handler brand new?
No. r410a runs at a much higher pressure.
What is the maximum reading on a typical r410a high pressure gauge?
800psig.
Can you mix r134a with r410a?
Can you mix r134a with r410a?
Can a R410A evaporator be used with a R22 condensor?
No, R410a runs higher pressures.
Hi can anyone tell me how to pump down a R410A systems with high and low pressure switches?
how long do a fuel pump last !
Can a R410A condensor be used with a R22 evaporator coil?
No, R410a runs higher pressures.
Is R410a freon compatible with R22?
No
What licence do you need to buy r-22 or r410a refrigerant?
R22 needs import license,R410A does not need anything special
Can you put r404a into an air conditioner designed for r410a?
No
How much R410 a freone does it take to contaminate a R22 freone system?
Any amount would be a contamination. Charging with clean R410a does not introduce POA oil, which is where a serious contamination would occur. Mixing R410a without oil will simply render that amount of charge in your system as ineffective. To answer the question how much contaminates, it could be seen on a sliding scale, a very small amount, say a couple ounces, probably will not see a noticeable change. A pound, and you would likely notice some changes in performance related to temps. of evaporator as well as the amount of liquid refrigerant its producing to send to the evaporator. As you increase the ratio of R410a to R22, you would only see incrementally worse performance as the compressor is not producing the pressure required to get any use of R410a. If you had somehow introduced R410a with its oil, their would be a serious reason to pull the entire charge, flush the system, and start clean. The oils of R22 and R410a are %100 not mixable, they will be rendered useless, and system damage will occur shortly.
