    Superheat and Subcooled Levels for Water Source Heat Pumps

    This paper evaluates and analyzes the superheat and subcooled levels for water source heat pumps. As per the non-ideal refrigeration cycle, each cycle has a certain amount of superheat in the suction line and a certain amount of subcooled liquid in the liquid line. By evaluating the level of measured superheat and subcooled levels for a known correctly charged system, we can document and publish the results for internal and external use. By connecting temperature gauges to the suction and liquid lines of a system, the superheat and subcooled levels of the system can be found relatively quickly. Charge can be declared to be correct if the values of the superheat and subcooled levels match those of the lab tested values.
