2014年1月9日 · Hi, good days all of you.. can I replace R507a to R22, cause R507a discharge pressure higher then R22. anyway, what is different between R507a with R22, can anyone share PT chart for R507a and R22 recently this is about the sea food cold storage system using BITZER S6F-30.2Y-40, the lowers discharge pressure resulting energy save ri

2016年2月2日 · I am reviewing something for hot climate where ambients can exceed 55C. So What should be the condensing temp assumed for R507A when considering condensor specs?

2004年11月29日 · Has anyone used Icors NU-22 NU-22 is the most practical and natural choice for the replacement of HCFC-22. It is the only HFC based R-22 replacement that is compatible with synthetic and mineral oils (MO,AB,POE).

2010年6月16日 · It is a Carlisle Compressor running on R507A. We are using Emkarate RL32H and a Temprite Model 506 oil seperator. The system runs through either a direct expansion valve or alternatively through a Motorised smart cool valve into a Heat Exchanger depending on the requirement of the unit at that point.

2008年10月17日 · The capacity of a plant with R404A will be about 3% higher than one working with R507A. At least most of the european heat exchanger manufacturers refer to this factor in their catalogues. 25-10-2008, 07:42 PM #7

It is proven that replacing the original R134a refrigerant in a Chip-Con Prometeia with R404a instantly decreases full-load CPU temperatures with 10-15 °C.

2014年7月24日 · if R404a & R507a &R134a as unacceptable what refrigerants can replace ?? 08-09-2014, 05:45 PM #23.

You won't need to do a oil change, r22 runs on ester oil OK. But the LTZ compressor is design for low temp applications, -20C evap, and correct me if I'm wrong, but r22 doesn't like going that low, the head pressure gets to high.

2004年8月1日 · How come R507A over R404A Peter? For the same compressor, you have more cooling capacity and the COP is also better. Bitzer 4V-6.2Y, -10°C/45°C, 5K Subcooling, ,10°C suction

hi guys please correct me, is it right in a cool room we should have temp below 4 deg above 1 so that's why i always look ate the suction pressure to be at -5 deg cel for any refrigerant (404,134,22) off course pressures will be different from ***** to *****. even in freezer if the temp has to be -18 i look for -25 suction pressure also i look at the sight glass to be clear as well.
