When wind cooling cold and hot water machine 10 worked in refrigeration mode, the second cross valve 810 powered on, 500 power down of the first cross valve, and magnetic valve 830 and the second expansion valve 870 are closed, and the first expansion valve 850 is opened, and cooling fan 730 is opened.At this moment, because magnetic valve 830 and the second expansion valve 870 are in closed condition, under the cooperation of the use state of the first cross valve 500, pass through successively First Heat Exchanger 200 and the second heat exchanger 300 to realize refrigerating function from compressor 100 exhaust outlets 110 cold media gas out.As shown in Figure 2, particularly, the HTHP cold media gas of exporting from compressor 100 exhaust outlets 110 respectively via valve port L1, L2 into and out of the second cross valve 810, and after through the second check valve 700 respectively via valve port S1, S4 into and out of the first cross valve 500.The cold media gas that flows out from valve port S4 enters the First Heat Exchanger 200 and is condensed into subcooled liquid, subcooled liquid enters the second heat exchanger 300 by the first expansion valve 850, and in the second heat exchanger 300, be vaporized, the overheated gas that produces enters the first cross valve 500 through valve port S2, and flow out the first cross valve 500 and flow into the gas returning port 130 of compressor 100 by valve port S3, so iterative cycles is finished process of refrigerastion.Above refrigerant flowing through channel can simply be expressed as: compressor 100 exhaust outlets 110---the second cross valve 810 (L1-L2)---the second check valve 700---the first cross valve 500 (S1-S4)---First Heat Exchanger 200---the first expansion valve 850---the second heat exchanger 300---first cross valve 500 (S2-S3)---compressor 100 gas returning ports 130.
When wind cooling cold and hot water machine 10 worked in heating mode, the first cross valve 500 and the second cross valve 810 powered on, and the second expansion valve 870 and magnetic valve 830 are closed, and the first expansion valve 850 is opened, and cooling fan 730 is opened.At this moment, because magnetic valve 830 and the second expansion valve 870 all are in closed condition, therefore under the cooperation of the use state of the first cross valve 500, flow through successively the second heat exchanger 300 and First Heat Exchanger 200 to realize heat-production functions from compressor 100 exhaust outlets 110 cold media gas out.As shown in Figure 3, particularly, from the HTHP cold media gas of compressor 100 exhaust outlets 110 output respectively via valve port L1, L2 advances, go out the second cross valve 810, and rear respectively via valve port S1 at second check valve 700 of flowing through, S2 advances, go out the first cross valve 500, the refrigerant gas that flows out from the first cross valve 500 enters to be arranged at the second heat exchanger 300 and is condensed into subcooled liquid, subcooled liquid enters First Heat Exchanger 200 gasifications behind the first expansion valve 850, overheated gas is flowed into the first cross valve 500 and is flowed out the gas returning port 130 that the first cross valve 500 flows into compressor 100 again by valve port S3 by valve port S4, and so iterative cycles is finished the function that heats separately.Above refrigerant flowing through channel can simply be expressed as: compressor 100 exhaust outlets 110---the second cross valve 810 (L1-L2)---the second check valve 700---the first cross valve 500 (S1-S2)---the second heat exchanger 300---the first expansion valve 850---First Heat Exchanger 200---first cross valve 500 (S4-S3)---compressor 100 gas returning ports 130.
When wind cooling cold and hot water machine 10 works in refrigeration+heat recovery mode, the first cross valve 500 and 810 power down of the second cross valve, magnetic valve 830 cuts out, and the first expansion valve 850 and the second expansion valve 870 are opened, and cooling fan 730 is opened.At this moment, after through the second cross valve 810, enter the 3rd heat exchanger 400 from compressor 100 exhaust outlets 110 cold media gas out and realize recuperation of heat, because magnetic valve 830 cuts out, the second expansion valve 870 and the first expansion valve 850 are opened, and out cold media gas further enters in the second heat exchanger 300 and finishes refrigeration from the 3rd heat exchanger 400.As shown in Figure 4, particularly, the HTHP cold media gas of exporting from the exhaust outlet 110 of compressor 100 is respectively via valve port L1, L4 advances, go out the second cross valve 810, then enter recovery section condensation load in the 3rd heat exchanger 400, out condensed fluid enters in the second heat exchanger 300 through the second expansion valve 870 and the first expansion valve 850 successively and flashes to overheated gas from the 3rd heat exchanger 400, overheated gas is respectively via valve port S2, S3 advances, go out the first cross valve 500, then flow into the gas returning port 130 of compressor 100, so repeatedly finish the mode of operation of refrigeration+recuperation of heat.Above refrigerant flowing through channel can simply be expressed as: compressor 100 exhaust outlets 110---the second cross valve 810 (L1-L4)---the 3rd heat exchanger 400---the second expansion valve 870---the first expansion valve 850---the second heat exchanger 300---first cross valve 500 (S2-S3)---compressor 100 gas returning ports 130.
When the hot water temperature in the water tank reached 40 degrees centigrade, the condensation side of the 3rd heat exchanger 400 load increased, and causes sufficiently condensation cold media gas of the 3rd heat exchanger 400, and therefore wind cooling cold and hot water machine 10 can't provide preferably refrigeration.At this moment, as shown in Figure 5, can open magnetic valve 830 and close the second expansion valve 870, the second expansion valve 870 so that refrigerant is no longer flowed through after out from the 3rd heat exchanger 400, but flow through successively the first check valve 600 and magnetic valve 830, then enter the first cross valve 500 and flow out the first cross valve 500 by valve port S4 by valve port S1, enter and further be condensed into subcooled liquid in the First Heat Exchanger 200, subcooled liquid enters in the second heat exchanger 300 after through the first expansion valve 850 and flashes to overheated gas, overheated gas enters in the first cross valve 500 and via valve port S3 via valve port S2 and flows out the first cross valve 500, flows at last compressor 100 gas returning ports 130.Above refrigerant flowing through channel can simply be expressed as: compressor 100 exhaust outlets 110---the second cross valve 810 (L1-L4)---the 3rd heat exchanger 400---the first check valve 600---magnetic valve 830---the first cross valve 500 (S1-S4)---First Heat Exchanger 200---the first expansion valve 850---the second heat exchanger 300---first cross valve 500 (S2-S3)---compressor 100 gas returning ports 130.
In this case, the second heat exchanger 200 has improved the condensation effect of refrigerant as the second condenser of wind cooling cold and hot water machine 10, and then has improved the refrigeration of system.Simultaneously, cooling fan 730 is in open mode and many grades of speed governing can be set is system radiating, and can regulate himself rotating speed according to actual conditions, and it is larger load, and rotating speed is higher, and is like this, can greatly improve the efficiency ratio of hot water temperature system when higher, energy-efficient.
Heat when wind cooling cold and hot water machine 10 works in+during heat recovery mode, the first cross valve 500 powers on, 810 power down of the second cross valve, and magnetic valve 830 and the first expansion valve 850 are opened, and the second expansion valve 870 cuts out, and cooling fan 730 is opened.At this moment, after through the second cross valve 810, enter the 3rd heat exchanger 400 from compressor 100 exhaust outlets 110 cold media gas out and realize recuperation of heat, the second expansion valve 870 is in closed condition because magnetic valve 830 is in open mode, therefore successively by the second heat exchanger 300 and First Heat Exchanger 200, realize heat-production functions from the 3rd heat exchanger 400 cold media gas out.As shown in Figure 6, particularly, from the HTHP cold media gas of exhaust outlet 110 output of compressor 100 respectively via valve port L1, L4 advances, go out the second cross valve 810, then enter recovery section condensation load in the 3rd heat exchanger 400, again successively through the first check valve 600 and magnetic valve 830, afterwards, respectively via valve port S1, S2 advances, go out the first cross valve 500 and enter the second heat exchanger 300 and be condensed into subcooled liquid, subcooled liquid enters First Heat Exchanger 200 after through the first expansion valve 850 again and flashes to overheated gas, overheated gas is respectively via valve port S4, S3 advances, go out the gas returning port 130 that the first cross valve 500 flows into compressor 100 again, so iterative cycles is finished and is heated+recuperation of heat.Above refrigerant flowing through channel can simply be expressed as: compressor 100 exhaust outlets 110---the second cross valve 810 (L1-L4)---the 3rd heat exchanger 400---the first check valve 600---magnetic valve 830---the first cross valve 500 (S1-S2)---the second heat exchanger 300---the first expansion valve 850---First Heat Exchanger 200---first cross valve 500 (S4-S3)---compressor 100 gas returning ports 130.
When wind cooling cold and hot water machine 10 worked in heat recovery mode, magnetic valve 830 and the first expansion valve 850 were closed, and the second expansion valve 870 is opened, and the first cross valve 500 powers on, 810 power down of the second cross valve.At this moment, after through the second cross valve 810, enter the 3rd heat exchanger 400 from compressor 100 exhaust outlets 110 cold media gas out and realize recuperation of heat.As shown in Figure 7, particularly, from the HTHP cold media gas of exhaust outlet 110 output of compressor 100 respectively via valve port L1, L4 into and out of the second cross valve 810, then enter recovery section condensation load in the 3rd heat exchanger 400, enter in the First Heat Exchanger 200 through the second expansion valve 870 again and flash to overheated gas, overheated gas flows into the gas returning port 130 of compressor 100 via valve port S4, S3 into and out of the first cross valve 500 respectively again, and so iterative cycles is finished recuperation of heat.Above refrigerant flowing through channel can simply be expressed as: compressor 100 exhaust outlets 110---the second cross valve 810 (L1-L4)---the 3rd heat exchanger 400---the second expansion valve 870---First Heat Exchanger 200---first cross valve 500 (S4-S3)---compressor 100 gas returning ports 130.
As seen from the above description, when wind cooling cold and hot water machine 10 worked in heat recovery mode, First Heat Exchanger 200 absorbed the surrounding environment heat so that subcooled liquid is flashed to overheated gas always.So, when ambient temperature was low, First Heat Exchanger 200 is easily frosting after work a period of time.At this moment, can operate the refrigerant flow direction control structure and wind cooling cold and hot water machine 10 is worked under the defrosting mode so that First Heat Exchanger 200 is defrosted.When wind cooling cold and hot water machine 10 worked in defrosting mode, magnetic valve 830 and the first expansion valve 850 were closed, and the second expansion valve 870 is opened, 500 power down of the first cross valve, 810 energisings of the second cross valve.At this moment, because the first cross valve 500 power down and the second cross valve 810 powers on, magnetic valve 830 and the first expansion valve 850 are in closed condition, therefore the high-temperature high-pressure refrigerant that the exhaust outlet 110 of compressor 100 is discharged enters First Heat Exchanger 200 and the 3rd heat exchanger 400 after successively through the second check valve 700 and the first cross valve 500, realize the defrost operation to First Heat Exchanger 200.As shown in Figure 8, particularly, from the HTHP cold media gas of exhaust outlet 110 output of compressor 100 respectively via valve port L1, L2 into and out of the second cross valve 810, and after through the second check valve 700 through valve port S1, S4 into and out of the first cross valve 500, then enter and be condensed into subcooled liquid and release heat in the First Heat Exchanger 200, therefore this heat can remove the frost of tying on the First Heat Exchanger 200; Subcooled liquid enters the 3rd heat exchanger 400 through the second expansion valve 870 again and is evaporated into overheated gas, overheated gas flows into the gas returning port 130 of compressor 100 via valve port L4, L3 into and out of the second cross valve 810 respectively again, and so iterative cycles is finished defrost function.Above refrigerant flowing through channel can simply be expressed as: compressor 100 exhaust outlets 110---the second cross valve 810 (L1-L2)---the second check valve 700---the first cross valve 500 (S1-S4)---First Heat Exchanger 200---the second expansion valve 870---the 3rd heat exchanger 400---second cross valve 810 (L4-L3)---compressor 100 gas returning ports 130.
Need to prove, owing between the gas returning port 130 of the first cross valve 500 and compressor 100, be provided with capillary 750, therefore, the wind cooling cold and hot water machine 10 that provides of the present utility model works in heat recovery mode lower time, capillary 750 can carry out resorption to the refrigerant in the second heat exchanger 300 sides, avoid wind cooling cold and hot water machine 10 when operation, to exist a large amount of refrigerants to be trapped in the second heat exchanger 300, improved the performance of wind cooling cold and hot water machine 10.
Wind cooling cold and hot water machine 10 of the present utility model, by the refrigerant flow direction control structure is set, the refrigerant flow direction control structure is connected to First Heat Exchanger 200, the second heat exchanger 300 and the 3rd heat exchanger 400, be used for control refrigerant selectively flow through First Heat Exchanger 200 and/or the second heat exchanger 300 and/or the 3rd heat exchanger 400, therefore controlling wind cooling cold and hot water machine 10 selectively works in the corresponding pattern, so, not only so that wind cooling cold and hot water machine 10 can work in a plurality of patterns, and further so that wind cooling cold and hot water machine 10 can realize utilizing recuperation of heat to produce the domestic hot-water.Moreover, when wind cooling cold and hot water machine 10 works in refrigeration+heat recovery mode, domestic hot-water's temperature of producing reach 40 the degree more than situation under, refrigerant can pass through First Heat Exchanger 200 further condensations, thereby has avoided in present wind cooling cold and hot water machine reaching 40 degree cooling system effect decline problem when above in domestic hot-water's temperature of producing.In addition, when wind cooling cold and hot water machine 10 works in defrosting mode, it can defrost to First Heat Exchanger 200, avoided First Heat Exchanger 200 frosting and shorten life-span of First Heat Exchanger 200 when ambient temperature is low, and, can not exert an influence to indoor heating when wind cooling cold and hot water machine 10 is operated in defrosting mode lower time, but also heat-recoverable is produced the domestic hot-water, can be fit to the winter cold district and use.
Should be understood that; it below only is preferred embodiment of the present utility model; can not therefore limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
