(54) | Water cooling system with full heat recovery |
(57) The present invention relates to a water cooling system with full heat recovery comprising
a condenser (3), an evaporator (9), a compressor (1) and an expansion valve (8); the
evaporator connects with a cooling water recycling circuit; one side of the condenser
(3) is disposed in a position corresponding to a cooling air opening (3-7); the cooling
air opening connects with an air pipe (16); the air pipe connects with an indoor air
outlet (17) and an outdoor air inlet (18) through subsidiary pipes (16-1;16-2); the
other side of the condenser is provided with an exhaust vent (3-5); and a cooling
fan (3-6) is disposed between the exhaust vent and the cooling air opening. The present
invention utilizes low temperature, low humidity indoor exhaust air as cooling air
for the evaporative condenser. It makes use of the sensible heat (temperature difference)
of indoor exhaust air as well as the latent heat (humidity difference) of indoor exhaust
air, thereby attaining better condensation effects.
