Heating system for swimming pool - has air treated by heat pump with some flow by=passed around evaporator with total flow passing over condenser

摘要

Air is extracted (2) from the swimming pool hall (1) and part of it (3) passes over the evaporator (s) of a heat pump. The air is cooled and moisture is condensed out of it. The remainder of the extract air flows in a bypass (4) round the evaporator and rejoins the cooled stream after the evaporator. The total flow then passes over the condenser (S) of the heat pump in which is is heated. A fan (13) returns the air from the condenser to the pool hall (1). The system allows regulation of the temperature and humidity of the returned air (15) and the bypass reduces the power requirements of the heat pump.
