The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As shown in Figure 1 and Figure 2, evaporating type condensing of the present utility model/cooling air conditioner cold water unit is evaporative condenser formula handpiece Water Chilling Units and the integrated handpiece Water Chilling Units of modified cooling tower that has the surface cooler precooling.
Evaporative condenser formula handpiece Water Chilling Units is made up of evaporimeter 1, compressor 2, condenser 3, choke valve 4.Evaporimeter 1, compressor 2 and condenser 3 are connected successively, and condenser 3 is connected with evaporimeter 1 by choke valve 4.
The modified cooling tower is made up of surface cooler 5, filler 6, water-locator 7, exhaust blower 8, water pump 9, water tank 10.Filler 6, water-locator 7 and exhaust blower 8 are successively set on the top of condenser 3, water pump 9 and water tank 10 are arranged on the bottom of condenser 3, water pump 9 is connected with water-locator 7 by pipeline, three air inlet places of cooling tower all are provided with surface cooler 5, and the waterway pipe of three surface coolers 5 adopts parallel form.
Evaporative condenser formula handpiece Water Chilling Units in evaporating type condensing/cooling air conditioner cold water unit part is utilized handpiece Water Chilling Units in summer evaporimeter provides low-temperature cold water for air-treatment unit and air-conditioner tail end equipment capable; Modified cooling tower part spring and autumn transition season utilize cooling tower to provide high temperature cold water for air-treatment unit and air-conditioner tail end equipment capable.
The course of work of the utility model handpiece Water Chilling Units:
The course of work of evaporative condenser formula handpiece Water Chilling Units wherein: the liquid refrigerant of low-temp low-pressure absorbs the heat in the air-conditioning backwater in evaporimeter 1, produce out low-temperature cold water, is used for air-treatment in summer unit and air-conditioner tail end equipment capable.Cold-producing medium after the vaporization is compressed into the gas of HTHP by compressor 2, the liquid of warm high pressure in condenser 3, being condensed into, and condenser institute liberated heat, cold water and the air outer by condenser tube carry away, and discharge outdoor by exhaust blower 8.In the liquid refrigerant of warm high pressure be reduced into the liquid refrigerant of low-temp low-pressure through choke valve 4 again, reenter evaporimeter, finish kind of refrigeration cycle.
