Innovative point of the present utility model is:

1, the refrigerant circulation loop of She Ji cooling/warming conditionner and hot water device is simple in structure: compare with existing cooling and heating air conditioner, technical scheme II of the present invention refrigerant loop in only between exhaust outlet of compressor and cross valve air inlet, added a hot water coagulation heat exchanger, by improvement, the cross valve that uses in gas circuit when changing feed liquor into, also can be switched freely in air inlet to the control gas circuit of cross valve; Therefore only adopt the switching of a cross valve, cooperate water circulating pump, outdoor machine fan, the start-stop of indoor machine fan, can organize heat water hold concurrently refrigeration, heat water, the gas that freezes, heat gas and the defrosting multi-functional air conditioner hot water machine of totally five kinds of circulations.Its successful key point is: the high-pressure pipe of the solenoid pilot valve of cross valve is directly linked on the compressor exhaust pipe, rather than intactly be connected on the air inlet pipe of cross valve main valve body.Because, higher pressure refrigerant gas by the hot water coagulation heat exchanger in heating the water circulation has condensed into liquid, the original air inlet of cross valve becomes liquid-inlet, the high-pressure pipe of the solenoid pilot valve that is connected with cross valve main valve body air inlet pipe can not obtain gases at high pressure, also just can't provide gases at high pressure, change the cross valve path direction to the piston cavity at cross valve main valve body two ends.The hot water coagulation heat exchanger that before the cross valve air inlet, increases in the refrigerant loop of technical scheme II, this point is innovation not very, because being a lot of patents of invention and utility model, this all mentions, but, if the control gas circuit of cross valve is not improved, multi-functional circulation just can not realize, can not reliable and stablely move in other words.Have only the full implementation of technical solution of the present invention II, be only feasible innovation.The switching construction of technical scheme is the simplest; But, when long-time kind of refrigeration cycle, the hot water of hot water coagulation heat exchanger otherwise the heat of the overheated gas of higher pressure refrigerant gas is received in disconnecting, temperature can slowly raise, and surely not surpasses the compressor air-discharging maximum temperature.

2 at the technical solution of the utility model I, than technical scheme II between the import of the gas outlet of the compressor of refrigerant loop and cross valve, add a triple valve, it makes simple high efficient and reliable cooling/warming conditionner and hot water device, remain with the function of cooling and heating air conditioner fully, and it is certain strictly to control the hot water temperature.Adopt the technical solution of the utility model I, heating two circulation times that water is held concurrently and freezed and heat water, first and second interface pressure of giving vent to anger of triple valve is equal substantially, interior leakage can not appear, improved stability, can all reclaim the condensation heat of compression refrigerant gas, the highest heat recovery efficiency has been arranged; And, heating water when holding concurrently kind of refrigeration cycle, the hot water coagulation heat exchanger is connected on before the outdoor wind heat exchanger, and outdoor wind heat exchanger is the subcooler of refrigerant liquid, can also improve refrigerating capacity.Technical scheme I has peak performance efficient.The key problem in technology point of guaranteeing technical scheme I success is: used triple valve and cross valve in the refrigerating circuit, all passed through transformation, the blast pipe of the solenoid pilot valve of the triple valve that is made into by existing cross valve is connected on the compressor suction duct, and the air inlet pipe of the solenoid pilot valve of the cross valve that is made into by existing cross valve is connected on the compressor exhaust pipe.There has been this improvement to make and switched reliably, stable performance.

3, adopt compact efficient formula hot water coagulation heat exchanger, miniaturization is made separately, the production efficiency height, and cost is low.Therefore, can be installed in the hot water coagulation heat exchanger in the outdoor casing, the hot water coagulation heat exchanger is connected with circulating water line with heat storage water tank, than connecting with the fluorine pipeline, not only be convenient to install and user's use, reduce the connecting line cost, and reduce the leakage probability of refrigerant loop.In addition, adopt water circulating pump forced circulation heat exchange mode, improved the heat transfer efficiency of hot water coagulation heat exchanger greatly, the Energy Efficiency Ratio of unit is further improved.

4, joining the heat storage water tank that water circulating pump uses is provided with water tank circulation water-in and water-out interface and replenishes water inlet, hot water effluent's interface, water tank cyclic water outlet interface is at the water tank foot, hot water effluent's interface should be from the water intaking of water tank peak level, and this design is that everybody adopts; But, the additional water inlet interface of the technical program, be not common water inlet in water tank bottom, but the water tank middle part water level of intaking; The water tank circulation water inlet interface of the technical program is not the water tank upper water level of intaking usually, but the water tank middle part water level of intaking; Water circulating pump is installed on the circulation inlet pipeline of hot water coagulation heat exchanger, the running water water inlet is not the water inlet that is connected water circulating pump, but in parallel with the recirculated water water outlet interface of hot water coagulation heat exchanger, receive on the cistern circulated water water inlet interface water tank middle part water level of promptly intaking; This design, be that to fully take into account heat pump the best operating mode of exerting oneself be that condensation temperature is in 35～50 ℃ of intervals, if the running water temperature is very low in the winter time, allow 7 ℃ of running water directly pass through the hot water coagulation heat exchanger when for example 7 ℃ of users take hot water continuously, the condensing pressure of heat pump can be very low, it is normal 30% that the exerting oneself of Teat pump boiler has only, and can not normally move; And design of the present utility model, the running water that replenishes enters the water tank middle part, and the hot water blending of cold water and water tank middle and lower part makes the circulating water temperature that enters the hot water coagulation heat exchanger far above the temperature of replenishing running water, be lower than the average water temperature of heat storage water tank again, be suitable for heat pump work again most.When the check valve of installing on the running water water inlet pipe avoided tap water pressure not enough, hot water outflow and force water circulation were normal in the heat storage water tank; Hot water effluent's interface of heat storage water tank is got heat storage water tank top water level, can allow the user obtain the hottest hot water; The non-bearing type heat storage water tank adopts ball float traction flexible pipe outlet pipe water inlet, no matter the water level height can be got hot water the hottest in the water tank.This design is comprehensive utilization thermodynamics, thermal conduction study and a hydromechanical principle.

In a word, owing to taked above-mentioned a plurality of invention measure, simple high efficient and reliable cooling/warming conditionner and hot water device of the present utility model, can adapt to and cold and hotly measure different and any allotment with the hot water demand, really realized comprehensive frigiopyretic dysentery usefulness, the utilization rate maximization of equipment year, the average annual maximized target of energy-saving efficiency; Structure is simplified most, has avoided the leakage problem of many valves, has solved in many heat exchangers multiloop heat pump water heater system, and the unbalanced difficult problem of cold-producing medium had improved operation stability of equipment when the loop that the various heat exchange device is formed was moved; Being easy to batch making, being easy to install, can reduce cost significantly, is the energy-conservation domestic hot-water's of producing of real science good equipment, has wide market prospects, will play a role in low-carbon economy, contributes.
