Referring to Fig. 1~Fig. 3, the present embodiment include outer machine 10 installed outdoors and install plate type heat exchanger 1 indoors, Water tank 2, described plate type heat exchanger 1 is provided with tube side runner 11 and shell-side flow path 12;Described outer machine 10 include compressor 3, Four-way valve 4, finned heat exchanger 5, reservoir 6, four-way valve 4 is provided with D interface, C interface, S interfaces and E interface, and compressor 3 goes out Mouth is connected with D interface, and import is connected with S interfaces;The two ends of finned heat exchanger 5 are connected with C interface and reservoir 6 respectively, liquid storage Check valve 7 is provided with the pipeline that the inlet 61 and liquid outlet 62 of device 6 are connected with finned heat exchanger 5;In plate type heat exchanger 1 The two ends of tube side runner 11 are connected with E interface and reservoir 6 respectively, and the inlet 61 and liquid outlet 62 of reservoir 6 are changed with board-like Check valve 7 is provided with the pipeline of the connection of hot device 1;The two ends of shell-side flow path 12 are connected formation with water tank 2 in plate type heat exchanger 1 Water-flow circuit, is provided with water pump 8 in water-flow circuit.
Refrigerant is circulated in the tube side runner 11 of outer machine 10 and plate type heat exchanger 1, by heat in plate type heat exchanger 1 Pass to the water in shell-side flow path 12;The life that water in shell-side flow path 12 is transferred heat in water tank 2 in water tank 2 is used Water;Check valve 7 is used to control the flow direction of refrigerant.
In the present embodiment, electric expansion valve 9 is provided with the liquid outlet 62 of reservoir 6, for being depressured.
In the present embodiment, hot-water coil pipe 21 is provided with water tank 2, the water circulation of water tank 2 is accessed at the two ends of hot-water coil pipe 21 Loop.Hot water in water-flow circuit flows through hot-water coil pipe 21, heat exchange occurs with the water in water tank 2, there is provided domestic hot-water.
In the present embodiment, water inlet 22 and delivery port 23 are provided with water tank 2, water inlet 22 is connected with water supply line, goes out The mouth of a river 23 is connected with domestic water interface.When domestic water is not enough in water tank 2, cold water can be automatically replenished, the weight in heat pump New heating.
Referring to Fig. 1~Fig. 2, it is necessary to during water heating, electricity on four-way valve 4, D interface connect with E interface, C interface and S interfaces company It is logical.
The operation principle of water heating is:
(1)The input of compressor 3 sucks the gaseous coolant of low-temp low-pressure, is compressed into the gas discharge of HTHP, leads to Cross D interface and E interface enters the tube side runner 11 of plate type heat exchanger 1;
(2)The gas of HTHP carries out heat exchange in plate type heat exchanger 1, and the gas of HTHP is cold at normal temperatures But liquid, is condensed into, cryogenic high pressure liquid refrigerants is formed;Meanwhile, the gas of HTHP is released heat and is used for heating shell side stream Water in road 12, makes water heat up and becomes hot water;
(3), by check valve 7 by reservoir 6, the refrigerant of outflow is by electricity for the refrigerant flowed out from plate type heat exchanger 11 Sub- expansion valve 9, pressure declines, and returns to than extraneous low temperature, forms low-temp low-pressure liquid refrigerants, the energy with heat absorption evaporation Power;
(4)The liquid refrigerants of low-temp low-pressure enters finned heat exchanger 5, itself evaporation after the heat in refrigerant absorption air, Become low temperature low pressure gas;
(5)Low temperature low pressure gas are by after C interface and S interfaces, returning to compressor 35 and being compressed again;
Refrigerant is and so on circulated, and is constantly absorbed heat from air, is compressed in compressor 3, is put in plate type heat exchanger 1 Heat, hot water preparing.
The cold water that hot water in shell-side flow path 12 is entered in hot-water coil pipe 21, with water tank 2 by the water-flow circuit of water tank 2 Heat exchange is carried out, the temperature of cold water rises in water tank 2 becomes hot water and used for life;Hot water radiator in the water-flow circuit of water tank 2 Become to flow back to shell-side flow path 12 after cold water and reheat, circulated with this.
The direction of arrow is the flow direction of water in Fig. 1, and the direction of arrow is the flow direction of refrigerant in Fig. 2.
Referring to Fig. 1, Fig. 3, when system needs defrosting, four-way valve 4 does not go up electricity, and D interface is connected with C interface, E interface and S Orifice.
The operation principle of defrosting is:
(1)The input of compressor 3 sucks the gaseous coolant of low-temp low-pressure, is compressed into the gas discharge of HTHP, leads to Cross D interface and C interface enters finned heat exchanger 5;
(2)The gas of HTHP is radiated in the heat exchanger of fin side, forms the discharge of cryogenic high pressure liquid refrigerants;Wing Then heat absorption is defrosted in piece heat exchanger 5;
(3)By check valve 7 by reservoir 6, the refrigerant of outflow passes through electronics to the refrigerant flowed out from finned heat exchanger 5 Expansion valve 9, pressure declines, and returns to than extraneous low temperature, forms low-temp low-pressure liquid refrigerants;
(4)The liquid refrigerants of low-temp low-pressure carries out hot friendship by check valve 7 into the tube side runner 11 of plate type heat exchanger 1 Change, itself evaporation after the heat of the refrigerant absorption reclaimed water of shell-side flow path 12 becomes low temperature low pressure gas;Water in shell-side flow path 12 dissipates Heat becomes the cold water of low temperature;
(5)The cold media gas of low-temp low-pressure from plate type heat exchanger 1 out after, by after E interface and S interfaces, returning to compression Machine 3 is compressed again;
Refrigerant is and so on circulated, and is compressed in compressor 3, and heat release in atmosphere defrosts to finned heat exchanger 5, Absorbed heat in plate type heat exchanger 1, produce the cold water of low temperature.
The hot water that cold water in shell-side flow path 12 is entered in hot-water coil pipe 21, with water tank 2 by the water-flow circuit of water tank 2 Heat exchange is carried out, the hot water cooling in water tank 2 becomes cold water;After cold water heat absorption in the water-flow circuit of water tank 2 becomes hot water Flow back to shell-side flow path 12 to freeze again, circulated with this.
The direction of arrow is the flow direction of water in Fig. 1, and the direction of arrow is the flow direction of refrigerant in Fig. 3.
Because defrosting process needs have hot water in water tank 2, therefore defrosting process is usually have many remaining hot waters in water tank 2 In the case of carry out.Defrosting has in the case of many remaining hot waters in water tank 2 and is defrosted in the short time without often carrying out once in a while. Not only facilitated but also do not consumed the energy, unnecessary hot water was preferably utilized.
Furthermore, it is necessary to illustrate, the specific embodiment described in this specification, as long as its part does not specify specific shape Shape and size, then the part can be any shape and size being adapted with its structure;Meanwhile, the title that part is taken Can be with difference.The equivalent or simple change that all constructions according to described in the utility model inventional idea, feature and principle are done, wraps Include in the protection domain of the utility model patent.
