(1) course of work during winter and summer two-purpose air conditioner system heat supply in winter of the present invention
Fig. 1 is the schematic diagram of the state that heats of winter and summer two-purpose air conditioner system of the present invention.When heating in the winter time, the spool position of first two-position four way change valve 12 and second two-position four way change valve 15 as shown in the figure, promptly, perpendicular to the pipeline that is attached thereto, at this moment, the first interface 12a, the 15a of first, second two-position four way change valve is connected respectively with their corresponding the 4th interface 12d, 15d, and the second interface 12b, 15b are connected respectively with their corresponding the 3rd interface 12c, 15c.
Start immersible pump 3, the water that constantly extracts in the heat-collection well 2 enters first heat exchange coil, 4 release heat to second heat exchange coil 6 that is coupled with it, and the current of lowering the temperature after the release heat return heat-collection well 2, and so forth circulation.Simultaneously under the effect of first circulating pump 8, heated liquid heat transfer medium in second heat exchange coil 6, such as water or anti-icing fluid etc., the first interface 12a and the 4th interface 12d of first two-position four way change valve 12 flow through, first circulating pump 8, arrive the 3rd heat exchange coil 9, heat is discharged to the cold-producing medium in the evaporimeter 10 of the heat pump 24 that is coupled with it, the first interface 15a and the 4th interface 15d of second two-position four way change valve 15 subsequently flow through, and flow back to second heat exchange coil 6 and continue heat absorption, circulation and so forth continues the cold-producing medium in the heat transferred evaporimeter 10.At this moment, compressor 13 in the heat pump 24 is in running order, under its effect, heated cold-producing medium becomes cryogenic gas in evaporimeter 10, the check valve 11 of flowing through, pre-heating temperature elevation in the solar energy hot water tank 26 of solar water heater 21, sucked by compressor 13 subsequently and enter condenser 14 release heat to the 4th heat exchange coil 17 after compression heats up, liquid heat transfer medium wherein flow to fin 18 in the load through the 3rd interface 15c of second two-position four way change valve 15 and the second interface 15b under the effect of the 3rd circulating pump 16, to reach the purpose to the load heating.Cold-producing medium becomes liquid by gas after the release heat, enters evaporimeter 10 once more after liquid refrigerant reduces pressure by expansion valve 23 and absorbs heats, begins new cyclic process.Flow through the liquid heat transfer medium of load through the 3rd interface 12c and the second interface 12b of first two-position four way change valve 12, and the 3rd circulating pump 16 flows back to 17 heat absorptions of the 4th heat exchange coil, circulation and so forth.
Course of work when (two) winter and summer two-purpose air conditioner system of the present invention freezes summer
Fig. 2 schematic diagram during refrigerating state that is winter and summer two-purpose air conditioner system of the present invention in summer.When freezing summer, the spool position of first two-position four way change valve 12 and second two-position four way change valve 15 as shown in the figure, promptly, be parallel to the pipeline that is attached thereto, at this moment, the first interface 12a, the 15a of first, second two-position four way change valve is connected respectively with their the corresponding second interface 12b, 15b, and the 3rd interface 12c, 15c are connected respectively with their corresponding the 4th interface 12d, 15d.
Start immersible pump 3, constantly the water that extracts in the heat-collection well 2 enters first heat exchange coil 4, because summer, the well water temperature was much lower with respect to environment temperature, therefore the water in first heat exchange coil 4 absorbs the heat in second heat exchange coil 6 that is coupled with it, promptly give the cooling of the liquid heat transfer medium in second heat exchange coil 6, current after the heat absorption return heat-collection well 2, and so forth circulation.
Under the effect of compressor 13, heat pump carries out work.Liquid heat transfer medium in the 3rd heat exchange coil 9 is under the effect of first circulating pump 8, carry out exchange heat with the cold-producing medium in the evaporator with heat pump 10, to be lowered the temperature behind the cold-producing medium in the heat transferred evaporimeter, the first interface 15a and the second interface 15b of second two-position four way change valve 15 flow through, flow to load, to the load cooling, reach the purpose of refrigeration in summer.Liquid heat transfer medium after the intensification is through the 3rd interface 12c and the 4th interface 12d of first two-position four way change valve 12, and first circulating pump 8, gets back to the 3rd heat exchange coil 9 that is coupled with evaporimeter 10 and continues heat release cooling, circulation so repeatedly.Simultaneously, the condenser 14 of heat pump 24 discharges heat to the 4th heat exchange coil 17, liquid heat transfer medium in the 4th heat exchange coil 17 is under the effect of the 3rd circulating pump 16, the 3rd interface 15c and the 4th interface 15d through second two-position four way change valve 15, flow back to second heat exchange coil 6, and heat discharged to first heat exchange coil 4, afterwards again through the first interface 12a of first two-position four way change valve 12 and the second interface 12b, the 3rd circulating pump 16, arrive the 4th heat exchange coil 17, heat in the absorptive condenser 14, circulation and so forth is constantly to load cooling refrigeration.
(3) winter and summer two-purpose air conditioner system of the present invention does not start the heat pump and the course of work when freezing summer
Fig. 3 is that winter and summer two-purpose air conditioner system of the present invention does not start heat pump and the schematic diagram when freezing summer.At this moment, the spool of first two-position four way change valve 12 is positioned at the position of level in the pipeline that is attached thereto, and the spool of second two-position four way change valve 15 is positioned at the position perpendicular to the pipeline that is attached thereto.At this moment, the first interface 12a of first two-position four way change valve 12 is connected with the second interface 12b, and the 3rd interface 12c is connected with the 4th interface 12d; The first interface 15a of second two-position four way change valve 15 is connected with the 4th interface 15d, and the second interface 15b is connected with the 3rd interface 15c.
Start immersible pump 3, constantly the water that extracts in the heat-collection well 2 enters first heat exchange coil 4, because summer, the well water temperature was much lower with respect to environment temperature, therefore the water in first heat exchange coil 4 absorbs the heat in second heat exchange coil 6 that is coupled with it, promptly give the cooling of the liquid heat transfer medium in second heat exchange coil 6, current after the heat absorption return heat-collection well 2, and so forth circulation.
In second heat exchange coil 6 through the liquid heat transfer medium of heat exchange cooling under the effect of first circulating pump 8 and the 3rd circulating pump 16, the 3rd interface 15c and the second interface 15b of the first interface 12a of first two-position four way change valve 12 and the second interface 12b, the 3rd circulating pump 16, the 4th heat exchange coil 17, second two-position four way change valve 15 flow through, flow to 18 pairs of load heat radiations of fin of load, reach the purpose of cooling refrigeration.Afterwards through the first interface 15a and the 4th interface 15d of the 3rd interface 12c of first two-position four way change valve 12 and the 4th interface 12d, first circulating pump 8, the 3rd heat exchange coil 9, second two-position four way change valve 15, flow back to the heat release cooling once more of second heat exchange coil 6, circulation so repeatedly, continuous low temperature with well water in the heat-collection well passes to the fin 18 in the load, reaches the purpose of cooling refrigeration.
More than describing is explanation of the invention, is not that institute of the present invention restricted portion is referring to claim to the qualification of invention, and under the situation of spirit of the present invention, the present invention can do any type of modification.
