Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and embodiments.
As shown in Figure 1-3, a kind of factory energy-saving water cycle heat exchange device, for providing cooling water for central air-conditioning；
The heat-exchanger rig includes plate heat exchanger and water cooler；The water cooler includes compressor, evaporator, condenser；It changes
Thermal includes cooling water pipeline and chilled water pipeline, and wherein the main pipeline of chilled water pipeline forms two component branch pipe(tube)s, respectively
The main pipeline of the chilled water pipeline of connecting plate type heat exchanger and the chilled water pipeline of evaporator, cooling water pipeline forms two group of branches
Pipeline is separately connected the cooling water pipeline of plate heat exchanger and the cooling water pipeline of condenser；It is all provided on each lateral
There is solenoid valve；The intersection of each lateral is equipped with the temperature inductor for detecting water temperature in pipeline；The temperature sense
The real-time water temperature numerical value for answering device will test connects main control PLC module by RS485 bus.
The heat-exchanger rig and cooling tower and cooling water pump form cooling water recirculation system, heat-exchanger rig also with chilled water
Pump, water segregator, central air-conditioning, water collector form freezing water circulation system.
Y-type filter is installed in the cooling water recirculation system of the plate heat exchanger.
The solenoid valve connects main control PLC module.
Water cooler includes compressor, evaporator, condenser.Compressor includes speed increasing gear 1, impeller 2, guide vane 3, main electricity
Motivation 8.There is liquid-gas separator 4 in evaporator 7.When work, compressor sucks the low-temperature low-pressure refrigerant gas after sweat cooling,
Then high temperature and high pressure gas is compressed into send to condenser 5；Pressure high temperature hot gas makes gas condensation become normal after condenser 5 is cooling
Warm highly pressurised liquid；When normal temperature high voltage liquid inflow heating power expansion valve 6, the damp steam of low-temp low-pressure is throttled into, package is flowed into and steams
Device 7 is sent out, the heat for absorbing the chilled water in evaporator declines coolant-temperature gage；Refrigerant after evaporation is sucked back into compressor again,
Next refrigeration cycle is repeated again.
It repeats the above process, i.e., the refrigerant of gasification is changed into liquid using water cooler again, sends central hollow back to
Adjust unit.During this, cooling tower is needed to provide cooling water.
Compared to hot summer, the cooler-water temperature of outdoor cooling tower output is about 30 degrees centigrades, in winter, room
The cooler-water temperature of outer cooling tower output is relatively low, and about 10 degrees Celsius or less.Therefore, can not have to open water cooler,
It can liquefy to the refrigerant of gasification.
When temperature is lower, the cooling water entrance and chilled water entrance of water cooler are controlled by PLC controller
Solenoid valve 10 is opened the solenoid valve 10 on the lateral of plate heat exchanger, is accessed.To which cooling water does not enter back into cold water
Unit.In the process, the reading of real-time monitoring temperature inductor 9, such as temperature drift then increase the output flow of cooling water pump.
Due to using open circuit cooling water to carry out heat displacement, Impurity Potential must cause shadow to plate heat exchanger performance in atmosphere
It rings.After plate heat exchanger is blocked by impurity, normal use will be unable to.Therefore, it is necessary to the filtering of Y type is added in plate heat exchanger
Device, and often clean the filter.The filter of plate heat exchanger will switch back into water cooler operation, after cleaning in cleaning
Restore plate heat exchanger operation again.
