The specific embodiment
Below in conjunction with drawings and Examples the present invention is described in detail.
A kind of multifunctional heat pump air-conditioner/water heater is made up of compressor 1, magnetic valve, hot water exchanger 2, four-way change-over valve, heating power expansion valve 8, one way stop peturn valve, indoor heat exchanger 13, temperature sensing controller and hot water storage tank 19 as shown in Figure 1; It is characterized in that:
A) compressor 1 is by the road successively by hot water exchanger 2, first four-way change-over valve 3, second four-way change-over valve 4, first check valve 5, fluid reservoir 6, device for drying and filtering 7, heating power expansion valve 8, the 4th check valve 9, outdoor heat exchanger 10, link to each other with the B end of first four-way change-over valve 3;
B) C of first four-way change-over valve 3 end links to each other with the G end of compressor 1 return-air mouth, second four-way change-over valve 4 respectively;
C) hot water exchanger 2 water sides are connected with hot water storage tank 19 circulation water inlet ends by water lines, and hot water storage tank 19 recycles water end (W.E.) and is connected through the water inlet end of water circulating pump 18 with hot water exchanger 2 by water lines; Water tank temperature-sensing element 20 is set on the coil pipe of hot water storage tank 19, coil pipe temperature-sensing element 21 is set on the coil pipe of outdoor heat exchanger 10;
D) pipeline is set between the 4th check valve 9 and the heating power expansion valve 8, this pipeline is connected with the F end of second four-way change-over valve 4 through magnetic valve 11, the 3rd check valve 12, indoor heat exchanger 13 successively;
E) pipeline being set between the 4th check valve 9 and outdoor heat exchanger 10 is connected with the import of fluid reservoir 6 through the 5th check valve 15;
F) at pipeline in parallel between the 5th check valve 15 and the fluid reservoir 6, between the 3rd check valve 12 and the indoor heat exchanger 13, second check valve 14 is set on this pipeline.
Heat recovery method is as follows:
When G) the air conditioner refrigerating operating mode was moved, the A of first four-way change-over valve 3, B end communicated, and C, D end communicates, and the E of second four-way change-over valve 4, F end communicates, and G, H end communicates, and water circulating pump 18 does not leave, and magnetic valve 12 is switched on.After refrigeration working medium goes out from compressor 1, flow through behind hot water exchanger 2, first four-way change-over valve 3, condensation heat release in outdoor heat exchanger 10, flow through again behind fluid reservoir 6, the device for drying and filtering 7, in heating power expansion valve 8 places throttling, in indoor heat exchanger 13, after the evaporation heat absorption, behind first four-way change-over valve 3 and second four-way change-over valve 4, sucked again at last, form a kind of refrigeration cycle by compressor.This moment since first check valve 5, the 4th check valve 9, second check valve 14 oppositely by effect, the working medium bypass line of can not flowing through; Because water circulating pump 18 does not leave, so hot water exchanger 2 does not participate in heat exchange.
H) air conditioner refrigerating is double heats water condition when operation, and the A of first four-way change-over valve 3, B end communicates, and C, D end communicates, and the E of second four-way change-over valve 4, F end communicates, and G, H end communicates, and water circulating pump 18 leaves, magnetic valve 12 energisings.This circulation is similar with the air conditioner refrigerating operating mode, and difference is that cistern circulated water pump 18 is opened, and hot water exchanger 2 participates in heat exchange, and condensation heat is used for freely producing hot water to the hot water storage tank heating in refrigeration, is operational mode the most efficiently.And in this operational mode, for the hot water that guarantees to produce sufficiently high temperature makes system's operating pressure again is not too high, the coil pipe temperature-sensing element 21 that is provided with on outdoor heat exchanger 10 coil pipes, when the outdoor heat exchanger coil temperature is higher than setting value, off-premises station blower fan 16 stops, when outdoor heat exchanger 10 coil temperatures were lower than setting value, off-premises station blower fan 16 changeed.
When I) heating the water condition operation, the A of first four-way change-over valve 3, D end communicates, and B, C end communicates, and the E of second four-way change-over valve 4, H end communicates, and F, G end communicates, and water circulating pump 18 leaves, magnetic valve 12 no powers.After refrigeration working medium goes out from compressor 1, condensation and in hot water exchanger 2 to hot water storage tank 19 heating, flow through again behind first four-way change-over valve 3, second four-way change-over valve 4, fluid reservoir 6, the device for drying and filtering 7, in heating power expansion valve 8 places throttling, after evaporation is absorbed heat in outdoor heat exchanger 10 at last, sucked by compressor 1 through first four-way change-over valve 3 again, form one and heat circulation.This moment, condensation heat all was used to heat hot water storage tank, so the water temperature of hot water storage tank 19 can fast rise.This operating mode all can be used throughout the year.
When J) the air-conditioning heating condition moved, the A of first four-way change-over valve 3, D end communicated, and B, C end communicates, and the E of second four-way change-over valve 4, F end communicates, and G, H end communicates, and water circulating pump 18 does not leave, magnetic valve 12 no powers.After refrigeration working medium goes out from compressor 1, flow through behind hot water exchanger 2, first four-way change-over valve, 3 backs, second four-way change-over valve 4, condensation heat release in indoor heat exchanger 13, flow through again behind fluid reservoir 6, the device for drying and filtering 7, in heating power expansion valve 8 places throttling, in outdoor heat exchanger 16, after the evaporation heat absorption, behind first four-way change-over valve 3, sucked again at last, form one and heat circulation by compressor 1.This moment since the 5th check valve 15, the 3rd check valve 12 oppositely by effect, the working medium bypass line of can not flowing through; Because water circulating pump 18 does not leave, so hot water exchanger 2 does not participate in heat exchange.
K) air-conditioning heats double water condition when operation of heating, and the A of first four-way change-over valve 3, D end communicates, and B, C end communicates, and the E of second four-way change-over valve 4, F end communicates, and G, H end communicates, and water circulating pump 18 leaves, magnetic valve 12 no powers.This circulation is similar with the air-conditioning heating condition, and difference is that cistern circulated water pump 18 is opened, and hot water exchanger 2 participates in heat exchange.When this mode operation, the user can select hot water mode prioritization or air conditioning mode preferential as required.Hot water storage tank is provided with water tank temperature-sensing element 20; When hot water was preferential, indoor set blower fan 17 stopped when the hot water storage tank temperature was lower than to design temperature, E, the H of second four-way change-over valve 4 end is logical, entered and heated aqueous mode; When water tank temperature was higher than design temperature, indoor set blower fan 17 started, E, the F end of second four-way change-over valve 4 is logical, and the operation air-conditioning heats the double aqueous mode that heats.
