Description
Technical field
The present invention relates to a kind of condensed water cold recovery and utilize central air conditioning plant.
Background technology
At present; The central air conditioner system of most of building adopts water-cooled handpiece Water Chilling Units+fan coil group system; The water-cooled handpiece Water Chilling Units provides 7 ℃ chilled water fan coil pipe unit; Be used for carrying out heat exchange with room air, coagulate cryogenic condensation water after the room air cooling, condensed water can be discharged through the condensate pipe of fan coil.But cryogenic condensation water holds certain cold is arranged,, can play energy-conservation effect if can recycle these colds and cooling water carries out heat exchange.
Summary of the invention
The object of the present invention is to provide a kind of condensed water cold recovery to utilize central air conditioning plant, it utilizes the cold of cryogenic condensation water and the cooling water of water-cooled handpiece Water Chilling Units to carry out heat exchange, practices thrift the operating cost of water quench, has practiced thrift energy consumption greatly.
The present invention realizes like this; Comprise chilled water water pump, water-cooled handpiece Water Chilling Units, three way flow control valve, plate type heat exchanger, temperature sensor A, temperature sensor B, cooling water water pump, electronic by-passing valve, cooling tower, outlet, condensed water water pump, condensate line, cooling water pipeline, chilled water pipeline, fan coil; It is characterized in that the water-cooled handpiece Water Chilling Units connects plate type heat exchanger, temperature sensor A, cooling tower, electronic by-passing valve, cooling water water pump and temperature sensor B successively through cooling water pipeline; Wherein, Electronic by-passing valve and cooling tower are connected in parallel, and the water-cooled handpiece Water Chilling Units connects several fan coils respectively through the chilled water pipeline, and several fan coils connect three way flow control valve, condensed water water pump, plate type heat exchanger and outlet successively through condensate line; Wherein three way flow control valve one end directly connects outlet; The other end connects the condensed water water pump, and condensate pump connects plate type heat exchanger, and plate type heat exchanger connects outlet.
The cooling water that it utilizes cryogenic condensation water in the fan coil to get into plate type heat exchanger and water-cooled handpiece Water Chilling Units carries out heat exchange, plays the effect of cold recovery utilization.Temperature sensor 1 measure in plate type heat exchanger with the condensed water heat exchange after cooling water temperature, when temperature is lower than cooling water backwater design temperature, regulate the aperture of three way flow control valve, make that the condensate flow through plate type heat exchanger reduces.When temperature is higher than cooling water backwater design temperature; Regulate the aperture of three way flow control valve, the feasible condensate flow that gets into plate type heat exchanger increases, when condensate flow increases big maximum; Temperature still is higher than cooling water backwater design temperature; Then close electronic by-passing valve, make cooling water get into cooling tower and cool off, the cooling fan flow of cooling tower is by temperature sensor 2 controls.
Technique effect of the present invention is, utilizes the cold of the cryogenic condensation water in water-cooled handpiece Water Chilling Units+fan coil units air-conditioning system that the cooling water of water-cooled handpiece Water Chilling Units is lowered the temperature, and is energy-saving and cost-reducing.
