Running pressures for 410a.

With 410a heat pumps is there a recommended suction pressure. For example with R22 air-con systems I always aim for 400 suction and 1500 discharge and similar with 407c systems. I have been told to aim for round the 100 psi/700kpa mark with is about 0 degree C Was just curious for fault finding purposes. Cheers in advance, chris.The low side pressure when the compressor is running is a feature of the compressor's own pumping power combined with the properties of whatever device is being used to meter refrigerant into the system. ... have 410a heat pump the compressor trips the internal replaced compressor still same starts with good pressures 330 high 125 low then ...So we replace the compressor (same model #), replace the liquid line filter dryer, and evacuate to 500 microns.

For example, if the HVAC system contains R-410a refrigerant, use the manifold gauges that you only use on R-410a systems to prevent contamination. Turn the thermostat to cool and set the target temperature at least 10 degrees lower than the indoor temperature. Let the system operate for at least 10 minutes to let pressures equalize.

R-410a is designed to operate at higher pressures than R-22. If you use R-22 in the same system as R-410a, the compressor is going to be trying to work two different fluids through the same coils as both refrigerants respond differently to different mechanical situations. As you might imagine, this isn't going to go well for your air ...

My LG mini-split air conditioning system wasn't putting out very cold air because it had leaked out most of the R410A refrigerant it had been installed with....Operating an air conditioner for extended periods of time in low temperatures outdoors lowers the suction pressure to a velocity where the oil will not return to the compressor and will run dry. Also, under low ambient conditions "indoors" does not provide sufficient load to change refrigerant from a liquid to a 100% vapor.1 Answers. by Muhammad Arsalan Siddiqui , MEP Project Manager , JLL. Systems using R-410A operate at higher pressures than R-22," points out the Field Diagnostics team.

However, this rule of thumb (obviously) does not work on an R-410A system. A more applicable guideline is 20°-25° suction saturation below outdoor ambient. Pressures: R22 vs 410A. The operating pressures of R22 and 410A are different, which affects how air conditioning systems are designed and function. R22 Pressure: R22 operates at lower pressures compared to 410A. This means systems designed for R22 cannot handle the higher pressure of 410A without modifications. demented bar and grill2011 buick enclave blend door actuator location Still learning the trade guys.
