WebJun 3, 2014 · In some cases, it benefits the system to incorporate some means of false-loading on the compressors. Both Rawal valves and Hot Gas Bypass provide a solution for this. In both cases, we're able to trick the compressor into staying on-line even if we do not have the load in the space. This keeps your coil energized leading to increased comfort … WebHot gas bypass is recommended when the load on an evaporator varies and operation of the air conditioning system is desired at lower than design conditions. Additionally, hot …

WebJan 11, 2024 · The compressed air is cooled in an air-to-refrigerant heat exchanger to about 35°F, a temperature where the moisture condenses and is drained off. An air-to-air heat exchanger is used to both pre-cool the incoming air, and re-heat the outgoing air as it leaves the dryer. The compressed air leaving the dryer has a pressure dew point of 35 to 50°F.

WebSep 9, 2004 · The basic function of the hot gas bypass is to keep the suction pressure above freezing during low load situations. Hot gas valve should start to feed at about 55lb suction and cut out at about 70lb, The hot gas is for keeping suction pressure up only and does not have any relation to leaving water temp. WebWhen hot gas is bypassed directly into the suction line, the danger exists of overheating the compressor and trapping the oil in the evaporator. As the suction temperatures rise, the discharge temperature like- wise starts to increase. This can cause breakdown of the oil and refrigerant with the possible result being a compressor burnout.
