ABSTRACT:
An environmental control system for controlling the environmental conditions in a swimming pool hall 1 comprises a heat pump having a multi-section evaporator 8, compressors 23a and 23b and a multi-section condensor 18.
In the day-time, the dry bulb temperature in the pool hall is maintained by circulating space air through a duct 3 to the evaporator 8 where the latent heat is recovered from the moisture laden air. This heat is rejected via the condensor 18 either to the now drier recirculated air or fresh air from an inlet 13 or a mixture of air from the two sources. In a night mode of operation, circulation of space air through the duct 3 is prevented and instead it is recirculated via a direct recirculation duct 53 and is heated by the condensor 18, the heat used to do this being recovered from outside air inducted into the evaporator 8 via an inlet 50. In order to prevent frosting of the evaporator when the outside air temperature is too low, a damper 52 may be opened to allow some space air to pass through the evaporator 8 and raise its temperature. In order to increase the heat recovery capability of the compressor, storage tank 56 is used to collect waste water from showers etc. and also from backwash through the pool water filter and when this tank is full, its water is chilled by means of a water chiller 15 in parallel with the evaporator and the heat so recovered is rejected to the re-circulating space air by means of the condensor 18.
