(5) specific embodiment:
Shown in Fig. 1-4: the utility model mainly by compressor 1, heat recovering heat exchanger 2, cross valve 3, evaporative condenser 4, evaporimeter 12, heating and health heat exchanger 14, freezing and heating expansion valve 10 and 7, cooling water pump 16, electric water treatment device 17 constitutes; The evaporative condenser 4 of band copper bar pipe and fin in the heat-pump air-conditioner is separated with miscellaneous parts such as compressor 1, evaporimeters 12, and place respectively in the space of two independently middle band dividing plates, and they are placed on the public supporting seat; It is that cooling fan 15, both sides are the version of copper bar pipe and fin 24 for tank 23, center upper portion that evaporative condenser 4 spaces of being with copper bar pipe and fin are made into the bottom, and the outside of copper bar pipe and fin 24 is an air inlet 25;
Its concrete connected mode is as follows:
A, compressor 1 are connected with heat recovering heat exchanger 2 by three-way solenoid valve 22;
B, heat recovering heat exchanger 2 tell four the tunnel again, be connected with following each device respectively: 1. passing ratio integration control valve 20 is connected with domestic hot-water's filling pipe, 2. be connected with health heat exchanger 14 with heating with proportional integral control valve 19 by electromagnetism two- port valve 21,3. directly be connected with domestic hot-water's case, 4. with three-way solenoid valve 22 and cross valve 3 between connecting line be connected.
C, compressor 1 are connected with gas-liquid separator 13;
D, gas-liquid separator 13 are connected with evaporative condenser 4 by cross valve 3.
E, heating are connected with following three-way connection (pipe) road again with health hot water heat exchanger 14: 1. be connected with evaporimeter 12 by three-way solenoid valve 18; 2. get back to heating and health hot water heat exchanger 14 again with after the heating return pipe is connected by three-way solenoid valve 18; 3. directly lead to domestic hot-water's case.
F, evaporimeter 12 respectively with the 1. loop connection that is connected with device for drying and filtering 11 by check-valves 9, refrigeration expansion valve 10; 2. be connected with evaporative condenser 4 by cross valve 3; 3. directly connect the heating return pipe.
The link circuit of g, check-valves 9, refrigeration expansion valve 10 and device for drying and filtering 11 is by fluid reservoir 8 backs and loop connection by check-valves 5, after heating expansion valve 6 and device for drying and filtering 7 being connected.
H, the loop by check-valves 5, after heating expansion valve 6 and device for drying and filtering 7 being connected are connected with evaporative condenser 4.
I, evaporative condenser 4 are connected in series with cooling water pump 16 and electric water treatment device 17 again.
In the drawings, when machine group selection refrigerating function, cooling fan 15, cooling water pump 16, electric water treatment device 17 start, and behind the high temperature and high pressure gas process heat recovering heat exchanger 2 from compressor 1, temperature is minimized, simultaneously the part heat is recycled to health hot water, entering evaporative condenser 4 through the cold media gas after the recuperation of heat is able to high-efficiency condensation and becomes liquid refrigerants, liquid refrigerants enters evaporimeter 12 after refrigeration expansion valve 10 throttlings, refrigerant is got back in the compressor after cold being exchanged to the recirculated water of air-conditioning system in evaporimeter.The water circulation pipe aspect, three-way solenoid valve is with water-water-to-water heat exchanger 14 bypass at this moment, and the backwater of air-conditioning system directly enters in the evaporimeter 12 without heat exchanger 14; Because of proportional integral valve 19 by the temperature sensor T on the air-conditioning system return pipe
2Provide signal, be in closed condition this moment, so only carry out recuperation of heat through heat recovering heat exchanger 2 from the health hot water of boiler.
When machine group selection heat-production functions, cooling water pump 16, electric water treatment device 17 quits work, from the high temperature and high pressure gas of compressor 1 since the action of three-way solenoid valve 22 with heat recovering heat exchanger 2 bypass, and because the action refrigerant system of cross valve carries out contrary circulation, high temperature and high pressure gas is after heat exchanger 12 is given air-conditioning system recirculated water with exchange heat, and be condensed into liquid refrigerant, refrigerant enters heat exchanger 4 after heating expansion valve 6 throttlings, get back to compressor behind the heat in absorbing atmosphere.Water circulation pipe aspect, the circulating water flow that this moment, three-way solenoid valve 18 action made air-conditioning system be through heat exchanger 14, the temperature sensor T on the return pipe of air-conditioning system
2When reaching set water temperature and providing signal, proportional integral valve 19 opens ratio so that the part exchange heat of air-conditioner circulating water is given health hot water.
The concrete technical scheme of the utility model is when machine group selection refrigerating function, cooling water pump and cooling fan start, the cooling water fin surface of flowing through from top to bottom, and the air water mean longitude is crossed fin, refrigerant is able to condensation thus, and electric water treatment device is effectively handled water quality simultaneously.Water from domestic hot-water's case carries out recuperation of heat so that the domestic hot-water to be provided through heat recovering heat exchanger.
When machine group selection heat-production functions, cooling water pump and electric water treatment device quit work, be able to condensation with air-cooled mode refrigerant, water from domestic hot-water's case no longer passes through heat recovering heat exchanger through motor-driven valve control, then enter heat exchanger with heating hot water, by the flow of proportional integral control valve, to guarantee the needs of heating earlier according to the return water temperature control health hot water of heating hot water.
The technical solution of the utility model key is should the heat exchange according to can satisfy winter heating the time to require to match according to the area of dissipation of various its evaporative condensers of model unit, and when freezing summer, can adopt converter technique control speed of cooling fan reducing air quantity and energy consumption because of required cooling air quantity is less, control signal by the temperature sensor senses condensation after the temperature of refrigerant provide.
