Air dehumidifying apparatus, particularly for use in a bathroom or swimming pool, comprising an air-to-air heat exchanger 10, an air-to-water heat exchanger 20 connected to a cold water supply and a drain (26, fig 2) for collecting condensate, wherein the air is received from the room by an inlet A and is cooled in the first flow path of the air-to-air heat exchanger, is then further cooled by the air-to-water heat exchanger before being reheated in the second flow path of the air-to-air heat exchanger and finally returned to the room by the outlet B. There may also be a fan 30 to move the air from the inlet A to the outlet B. Preferably there is a sensor which detects the flow of water through the air to water heat exchanger and controls the fan, which may be arranged so there is a delay between the water flow starting/stopping and the fan starting/stopping. |
