The discharge temperature of R22 is quite high, hence the degree of superheat in the systems using this refrigerant should be minimum. When the thermo is turned off, it memorizes the chiller water inlet temperature. It is worth noting that severely high compression ratios (low suction, high head) are more common in refrigeration applications as a cause of compressor overheating. The Scroll’s ability to handle liquid refrigerant makes it extremely reliable and, in low temperature applications, liquid injection is provided to lower discharge temperatures under adverse conditions. ※Don't use cleaning agents containing chlorine for cleaning circuits. • Temperature glide occurs when a refrigerant has a range of temperature in which it will boil and condense at one pressure.
