Superheat and Subcooled Levels for Water Source Heat Pumps
Content provided by AAON
This paper evaluates and analyzes the superheat and sub-cooled 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 sub-cooled liquid in the liquid line. By evaluating the level of measured superheat and sub-cooled 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 sub-cooled levels of the system can be found relatively quickly. Charge can be declared to be correct if the values of the superheat and sub-cooled levels match those of the lab tested values.
