When many on-line systems 10 work in refrigeration mode; First cross valve 510 and 520 power down of second cross valve, the first magnetic valve loop 530 and the second magnetic valve loop 540 are closed, at this moment; The HTHP cold media gas of being exported from compressor 100 exhaust outlets 110 advances/goes out first cross valve 510 via valve port S1 and S2 respectively; Advance/go out second cross valve 520 via valve port L2 and L3 respectively afterwards, then, get into first heat exchanger 210 and be condensed into subcooled liquid; Subcooled liquid gets into indoor set main body 330 through the throttling arrangement 600 and first tube connector 310; And gasified in second heat exchanger 350 in being arranged at indoor set main body 330, the overheated gas that is produced advances/goes out second cross valve 520 via valve port L1 and L4 respectively and flows into the return-air mouth 120 of compressor 100, and process of refrigerastion is accomplished in circulation so repeatedly.But above refrigerant flowing through channel simple table is shown: compressor 100 exhaust outlets 110---first cross valve 510 (S1-S2)---second cross valve 520 (L2-L3)---first heat exchanger 210---throttling arrangement 600---first tube connector 310 of second heat exchanger assembly 300---second heat exchanger 350---second cross valve 520 (L1-L4)---compressor 100 return-air mouths 120.
When many on-line systems 10 worked in heating mode, first cross valve 510 powered on, 520 power down of second cross valve, and the first magnetic valve loop 530 and the second magnetic valve loop 540 are closed.At this moment; Advance/go out first cross valve 510 via valve port S1 and S2 respectively from the HTHP cold media gas of compressor 100 exhaust outlets 110 outputs; Advance/go out second cross valve 520 via valve port L2 and L1 respectively again; Then, first tube connector 310 through second heat exchanger assembly 300 enters into a plurality of second heat exchangers 350 and is condensed into subcooled liquid, and subcooled liquid gets into 210 gasifications of first heat exchanger after throttling arrangement 600 throttlings; Overheated gas advances/goes out the return-air mouth 120 that second cross valve 520 flows into compressor 100 again via valve port L3 and L4 respectively, and so the function that heats is separately accomplished in circulation repeatedly.But above refrigerant flowing through channel simple table is shown: compressor 100 exhaust outlets 110---first cross valve 510 (S1-S2)---second cross valve 520 (L2-L1)---first tube connector 310 of second heat exchanger assembly 300---second heat exchanger 350---throttling arrangement 600---first heat exchanger 210---second cross valve 520 (L3-L4)---compressor 100 return-air mouths 120.
When many on-line systems 10 work in heat recovery mode; First cross valve 510 and second cross valve 520 power on; The first magnetic valve loop 530 is closed, and open in the second magnetic valve loop 540, at this moment; The HTHP cold media gas of being exported from compressor 100 exhaust outlets 110 advances/goes out first cross valve 510 via valve port S1 and S4 respectively; Become subcooled liquid in second tube connector, 410 entering the 3rd heat exchanger 430 through the 3rd heat exchanger assembly 400 afterwards, subcooled liquid advances/goes out second cross valve 520 via valve port L2 and L1 respectively after through first check valve 850, then; Through the second magnetic valve loop 540; And after through throttling arrangement 600 throttlings, flash to overheated gas in entering first heat exchanger 210, and overheated gas flows into the return-air mouth 120 of compressor 100 again after advancing/go out second cross valve 520 via valve port L3 and L4 respectively, and the independent heat recovery mode of circulation completion is produced the domestic hot-water or is realized base plate heating with realization so repeatedly.The approach that above refrigerant is flowed through can be shown by simple table: compressor 100 exhaust outlets 110---first cross valve 510 (S1-S4)---second tube connector 410 of the 3rd heat exchanger assembly 400---the 3rd heat exchanger 430---first check valve 850---second cross valve 520 (L2-L1)---the second magnetic valve loop 540---throttling arrangement 600---first heat exchanger 210---second cross valve 520 (L3-L4)---compressor 100 return-air mouths 120.
Can know that by above content when working in heat recovery mode following time, refrigerant is without second heat exchanger assembly 300, also promptly, this moment refrigerant without a plurality of indoor sets, therefore can avoid refrigerant to be trapped in the problem of indoor set, improved the reliability of system.
When many on-line systems 10 worked in refrigeration heating recovery pattern, first cross valve 510 powered on, 520 power down of second cross valve, and open in the first magnetic valve loop 530, and the second magnetic valve loop 540 is closed.At this moment; The HTHP cold media gas of being exported from the exhaust outlet 110 of compressor 100 is after advancing/go out first cross valve 510 via valve port S1 and S4 respectively; Again through the 3rd heat exchanger assembly 400 recovery section condensation loads; The cold media gas that comes out from the 3rd heat exchanger assembly 400 advances/goes out second cross valve 520 via valve port L2 and L3 respectively after first check valve 850 of flowing through; Then, get in first tube connector 310 of second heat exchanger assembly 300 through the first magnetic valve loop 530 and throttling arrangement 600 again, and get in each second heat exchanger 350 that is arranged at each indoor set main body 330 through first tube connector 310 and to flash to overheated gas; Then advance/go out second cross valve 520 via valve port L1 and L4 respectively and flow into the return-air mouth 120 of compressor 100, accomplish the mode of operation of refrigeration heating recovery so repeatedly.But above refrigerant flowing through channel simple table is shown: compressor 100 exhaust outlets 110---first cross valve 510; (S1-S4)---second tube connector 410 of the 3rd heat exchanger assembly 400---the 3rd heat exchanger 430---first check valve 850---second cross valve 520; (L2-L3)---the first magnetic valve loop 530---throttling arrangement 600---first tube connector 310 of second heat exchanger assembly 300---second heat exchanger 350---, second cross valve 520; (L1-L4)---compressor 100 return-air mouths 120.
In this case; When in running order indoor set more after a little while; Compressor 100 low-frequency operations cause the 3rd heat exchanger 430 exchange capability of heat too big, at this moment; Can join the water yield to control the 3rd heat exchanger 430 recuperation of heat side heats through control variable frequency pump 450, guarantee the system high efficiency energy-saving run.
When the hot water temperature in the 3rd heat exchanger 430 reached 40 degrees centigrade, the condensation side of the 3rd heat exchanger 430 load increased, and causes the 3rd heat exchanger 430 condensation cold media gas fully, and therefore system can't provide refrigeration preferably.At this moment, the first magnetic valve loop 530 is closed.After the first magnetic valve loop 530 was closed, the refrigerant that is flowed out from the 3rd heat exchanger 430 was after flowing out second cross valve 520 via valve port L3, and first heat exchanger 210 of can flowing through further is condensed into subcooled liquid.In this case, second heat exchanger 210 is as second condenser of many on-line systems 10, further condensation refrigerant and improve the refrigeration of many on-line systems 10.Simultaneously, the fan 230 of first heat exchanger assembly 200 can be in open mode and many grades of speed governing are set is system radiating, and can regulate himself rotating speed according to actual conditions; It is big more to load, and rotating speed is high more, so; Can improve the efficiency ratio of hot water temperature system when higher greatly, energy-efficient.
When the hot water water temperature in the 3rd heat exchanger 430 arrives predetermined temperature; 510 power down of first cross valve are switched; Therefore refrigerant no longer flows out first cross valve 510 from valve port S4, flows out first cross valve 510 but change into from valve port S3, and flows through successively through second cross valve 520, first heat exchanger 210 and second heat exchanger assembly 300; And flowing into compressor 100 return-air mouths 120 through second cross valve 520, therefore system changes into and works in single refrigeration mode.And on the other hand; When the cold air of being exported when all indoor set main bodys 330 all reaches design temperature, the switching that powers on of second cross valve 520, open in the second magnetic valve loop 540; After therefore refrigerant flows out from the 3rd heat exchanger assembly 300; Flow through no longer successively second cross valve 520, the first magnetic valve loop 530 and throttling arrangement 600 and get into second heat exchanger assembly 300, but after flowing out second cross valve 520 via valve port L1, the second magnetic valve loop 540 of flowing through successively, first heat exchanger 210, second cross valve 520; And finally flowing into the return-air mouth 120 of compressor 100, therefore system changes under the pattern that works in recuperation of heat.When many on-line systems 10 work in when heating the heating recovery pattern; First cross valve 510 and second cross valve 520 power on; The first magnetic valve loop 530 and the second magnetic valve loop 540 are closed; At this moment; At second tube connector 410 that into and out of first cross valve 510 after, gets into the 3rd heat exchanger assembly 400 respectively via valve port S1, S4, through second tube connector, 410 entering the 3rd heat exchanger, 430 recovery section condensation loads, the cold media gas that comes out from the 3rd heat exchanger 430 advances/goes out second cross valve 520 via valve port L2 and L1 respectively after first check valve 850 of flowing through again from the HTHP cold media gas of the exhaust outlet of compressor 100 110 outputs; Then; Get into first tube connector 310 of second heat exchanger assembly 300, and get into second heat exchanger 350 that is arranged in the indoor set main body 330 through first tube connector 310 and be condensed into subcooled liquid, subcooled liquid gets into first heat exchanger 210 again through throttling arrangement 600 and flashes to overheated gas; Overheated gas advances/goes out the return-air mouth 120 that second cross valve 520 flows into compressor 100 afterwards via valve port L3 and L4 respectively, and circulation is accomplished to heat and added the portion of hot recovery so repeatedly.But above refrigerant flowing through channel simple table is shown: compressor 100 exhaust outlets 110---first cross valve 510 (S1-S4)---second tube connector 410 of the 3rd heat exchanger assembly 400---the 3rd heat exchanger 430---first check valve 850---second cross valve 520 (L2-L1)---first tube connector 310 of second heat exchanger assembly 300---second heat exchanger 350---throttling arrangement 600---first heat exchanger 210---second cross valve 520 (L3-L4)---compressor 100 return-air mouths 120.
When the water temperature in the 3rd heat exchanger 430 reaches predetermined temperature; 510 power down of first cross valve are switched; Therefore the cold media gas of being discharged from compressor 100 no longer flows out first cross valve 510 via valve port S4, but flows out first cross valve 510 via valve port S2, and flow through successively second cross valve 520, second heat exchanger assembly 300 and first heat exchanger 200; Therefore flow into the return-air mouth 120 of compressor 100 at last, system changes into and works under single heating mode.And the hot gas of being exported when all indoor set main bodys 330 is when all reaching design temperature; Open in the second magnetic valve loop 540; Refrigerant after flowing out second cross valve 520 via valve port L1, second heat exchanger assembly 300 of no longer flowing through, but flow through the successively second magnetic valve loop 540, throttling arrangement 600 and first heat exchanger 210; And via second cross valve, 520 inflow compressors, 100 return-air mouths 120, therefore system changes under the pattern that works in recuperation of heat.
Many on-line systems 10 of the utility model; Flow to Control Component 500 first heat exchanger 210, second heat exchanger 350 and the 3rd heat exchanger 430 are together in series through refrigerant is set; Be used to control refrigerant whether flow through first heat exchanger 210 and/or second heat exchanger 350 and/or the 3rd heat exchanger 430; Therefore control many on-line systems 10 and selectively work in the corresponding pattern, simple to operate, control easily.Moreover; When many on-line systems 10 work in refrigeration heating recovery pattern; Reach under the situation more than 40 degree the hot water temperature who is produced; Refrigerant can pass through the 230 further condensations of second heat exchanger, has avoided in present many on-line systems reaching 40 degree system's refrigeration decline problem when above the hot water temperature who is produced.In addition, when many on-line systems 10 work in refrigeration heating recovery pattern, can regulate the heat of the 3rd heat exchanger 430 recuperation of heat sides, guarantee the security of system reliability service through variable frequency pump 450.Simultaneously, when many on-line systems 10 work in heat recovery mode following time, refrigerant is without second heat exchanger assembly 300, also promptly, this moment refrigerant without a plurality of indoor sets, therefore can avoid refrigerant to be trapped in the problem of indoor set, improved the reliability of system.
