This new, colorless gas has only a minute impact on the atmosphere. It breaks down chemically in the atmosphere after just 11 days, compared to 13 years for R134a, according to research by Chemours. WebThis Figure shows a roof-mounted air-cooled chiller with a remote evaporator inside the building. 1. There are two refrigeration circuits, each with a liquid line supplying liquid refrigerant from the condenser to a TX valve adjacent to the evaporator, and a suction line returning refrigerant gas from the evaporator to the suction connections of the compressor. green waste pick up bunbury
