Heat-exchange device 2 also comprises heat-insulation layer 16, and heat-insulation layer 16 coats outer surface, storage tank 9 outer surfaces and fuel reserve tank 10 outer surfaces of each heat exchange condenser unit, is used for insulation.
The concrete course of work of this circulatory system is as follows:
After the energising, magnetic valve 6 is opened, compressor 1 connection work, by compressor 1 with the gaseous refrigerants in the evaporimeter 8 be compressed into high pressure, high-temperature gas flows to heat-exchange device 2; Cold water enters from cold water inlet in second drainer of second heat exchanger simultaneously, and degreasing fluid or electroplate liquid enter from fuel reserve tank 10 in first drainer of first heat exchanger.
In heat-exchange device 2, high pressure-temperature gas is by the passage of condensing gas, respectively with first drainer and second drainer in water, degreasing fluid and electroplate liquid carry out heat exchange, because second heat exchanger is positioned at the afterbody of condensing gas passage, therefore behind the water and condensing gas heat exchange in its second drainer, the temperature of water can reach 55-65 ℃, and that the heat exchange condenser unit that first heat exchanger comprises is positioned at the prime and the quantity of condensing gas passage is many, the heat exchange of degreasing fluid in the drainer or electroplate liquid and condensing gas is more abundant, after the heat exchange, the temperature of degreasing fluid or electroplate liquid can reach 90-100 ℃.Middle warm water comes out to enter in the storage tank 9 from the heat exchange condenser unit, and then enters passivation with carrying out water passivation cleaning treatment in the tank; The degreasing fluid or the electroplate liquid that flow out from liquid reserve tank 10 flow out through the heat exchange condenser unit, and generation high temperature degreasing fluid (or electroplate liquid) enters and carries out oil removing (or plating) in the degreasing tank (or electroplating bath).
Condensing gas through heat-exchange device 2 heat exchanges enters in the condenser 3, further passes through the air-cooled or water-cooling of fan in the condenser 3, becomes highly pressurised liquid, enters in the fluid reservoir 4.
Liquid refrigerant enters filter 5 by fluid reservoir 4 more under pressure and filters out impurity in the cold-producing medium, and the magnetic valve through opening 6 enters expansion valve 7 then.
Liquid refrigerant explosive decompression behind expansion valve 7 expands, and temperature descends rapidly simultaneously, and this low-pressure low-temperature cold-producing medium enters in the evaporimeter 8 because pressure reduces suddenly, the rapid explosive evaporation of liquid refrigerant and in evaporimeter 8 heat absorption become gas.
If evaporimeter 8 places cold water storage cistern, then cooled dose of heat absorption of the water in the cold water storage cistern becomes cold water, thereby realizes that cooling-water machine provides the function of cooling water; If evaporimeter 8 places air, then cooled dose of heat absorption of air becomes cold air, plays the effect that air conditioner is regulated ambient air.
Embodiment two: a kind of chemical industry heating means, comprise the steps: 1) condenser pipe in the heat-exchange device 2 in conductive fluid and the heat-pump-type heat-exchange apparatus is carried out heat exchange, described heat-pump-type heat-exchange apparatus is realized circulation successively as follows: through compressor, heat-exchange device 2, condenser, evaporimeter and expansion valve 7.2) when heating-up temperature still can not meet the demands, adopt electric heating tube further to heat conductive fluid.3) this conductive fluid is carried out heat exchange as heating fluid and chemical industry with equipment or agent liquid.
When said method specifically is applied at plastic industry, at first conduction oil is poured in the drainer in the heat-exchange device in the heat-pump-type heat-exchange apparatus, conduction oil and condenser pipe carry out heat exchange, conduction oil through heating pumps in the copper pipe, described copper pipe is surrounded on around the charging basket of injection machine or drying machine, the injection machine fuselage is carried out around heating, when need heating, this heater surpasses 140 ℃ and constant temperature and existing when adding deep fat and can not meet the demands, for example the temperature requirement of fuselage or mould surpasses 130 ℃, then can adopt electric heater that conduction oil is assisted heating and realized thermostatic control.
When specifically being applied to rubber machine mould, said method heats, then the heating of its process and injection machine is basic identical, difference is the conduction oil through the condenser pipe heating, copper pipe is twined in periphery at the rubber mold cover, described conduction oil through heating can flow in the copper pipe that is wound in rubber die sleeve periphery, rubber mold is added cover heat, if mold temperature requires above 140 ℃, before flowing into the peripheral copper pipe of rubber mold cover, with auxiliary heating of electrical heating and automatic constant-temperature.
More than three kinds to utilize cooling-water machine or air conditioner waste heat be to belong to the present world to initiate practical energy-conservation patent.
This method specifically is applied to rubber industry hydraulic press and plastic industry injection machine; its cardinal principle be condenser drainer the inside dress be conduction oil; it is emitted the long-pending heat of heat energy and heats up through the absorption condensation pipe by the conduction oil of a plurality of drainers; its temperature can reach about 140 degrees centigrade; serve the insulation fuel reserve tank then; send high temperature oil to the rubber machine by fuel reserve tank then; in the hydraulic press mould cage plate; but surpass 140 ℃ of its temperature of high temperature additional electric heaters if desired and can be raised to 200 degrees centigrade; first evaporimeter can cool off hydraulic press hydraulic oil space in addition; run well to protect machinery; after first evaporator cools oil temperature achieves the goal; notify the starting of conversion second evaporimeter by the temperature detector number of delivering a letter then to the IC micro-control; discharge cold air; regulate the workshop air temperature; the injection molding machine of plastic principle is identical with the rubber hydraulic press with way, and the heating and cooling system is also arranged.
In a word, the energy recovery of changes in temperature heat of the present invention three usefulness heat exchanges can reach 98%, with respect to the existing electric heating tube of electroplating in the chemical industry, changes in temperature heat three usefulness heat-exchange devices just can reduce 24 kilowatts of electric heating tubes, can also reduce the wear and tear expense 1000-2000 unit/moon of electric heating tube; Except effect economically, utilize the heating of used heat circular heating, can also avoid electrically heated toxic emission, reach the purpose of environmental protection.The maximum practical uniqueness of the present invention is to compile air heat pump and water source heat pump technology is an one, adopt two condensations, two evaporation multifunctional and multipurpose collection world waste heat elite, give full play to the principle that heat pump condensation radiating principle is got its waste heat heating water, the heat absorption of fortune thermo-compression evaporation, make principle its performance to the greatest extent of heat extraction and heat absorption, reaching the peak of using energy source, also solved the problem of environment heat island, is that best ball is protected, safe, energy-conservation, the practical technique of saving money.
