Specific embodiment

To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below In conjunction with specific embodiment, the utility model is further described.

In this application unless specifically defined or limited otherwise, term " connection " shall be understood in a broad sense, for example, can be with It is to be fixedly connected, may be a detachable connection, or is integral；It can be mechanical connection, be also possible to be electrically connected；It can be straight It connects connected, the connection inside two elements or the phase interaction of two elements can also be can be indirectly connected through an intermediary With relationship.For the ordinary skill in the art, above-mentioned term can be understood in the utility model as the case may be In concrete meaning.

As shown in Figure 1-3, the utility model provides a kind of refrigeration equipment for improving air-conditioning Energy Efficiency Ratio, including compressor 1, cold Condenser 2, expansion valve 3, evaporator 4, thermoelectric generator 6 and battery 7.

The entrance of the outlet of the entrance, condenser 2 of the outlet and condenser 2 of compressor 1 and expansion valve 3, expansion valve 3 go out Mouthful with the entrance of evaporator 4 respectively with piping connection.

Thermoelectric generator 6 includes collection warmware 61, radiating piece and the thermo-electric generation being arranged between collection warmware 61 and radiating piece Part 62.Collect warmware 61 to be arranged at 2 air outlet of condenser, collection warmware 61, which can be, to be directly anchored on condenser 2, is also possible to It is fixed on by other bracket at the air outlet of condenser 2.The both ends of thermo-electric generation part 62 respectively with collection warmware 61 and heat dissipation Part keeps good contact, and thermo-electric generation part 62 is electrically connected by conducting wire with battery 7, and preferably battery 7 is arranged in condenser 2 On, battery 7 is connect with the fan etc. in air-conditioning with electrical component by conducting wire.

As a further improvement of the foregoing solution, collection warmware 61 includes frame 601 and the heat collecting sheet being arranged on frame 601 602, frame 601 is fixedly connected with condenser 2, and heat collecting sheet 602 is fixed on frame 601.The material and condenser of heat collecting sheet 602 The material of cooling fin in 2 is identical.Structure is simple, easy for installation.It is preferred that the bending of heat collecting sheet 602 forms an angle, the angle is excellent It is selected as acute angle, such hot wind is longer from the path passed through between heat collecting sheet 602, and the effect of 602 thermal-arrest of heat collecting sheet can be more preferable.

As a further improvement of the foregoing solution, radiating piece is heat-dissipating pipe 63, has the heat exchange of flowing in heat-dissipating pipe 63 Medium, heat-dissipating pipe 63 are externally provided with thermal insulation material 9.Certainly, the part that heat-dissipating pipe 63 is in contact with thermo-electric generation part 62 is not provided with Thermal insulation material 9.Heat exchange medium can be water, and in this case, 63 one end of heat-dissipating pipe is connect by a water pipe with tap, The other end is connect by another water pipe with drainpipe.And heat-dissipating pipe 63 is at flat or at snakelike be distributed in thermo-electric generation part 62 one end, it is therefore an objective to increase the contact area of heat-dissipating pipe 63 Yu thermo-electric generation part 62.Electromagnetism is equipped on an above-mentioned water pipe Valve, for controlling the on-off of water flow.Solenoid valve is controlled by the control system 5 of air-conditioning.The lower sluggish flow of temperature from heat dissipation Pass through in pipe 63, to achieve the purpose that heat dissipation.

Preferably, the heat exchange medium is the refrigeration to circulate in compressor 1, condenser 2, expansion valve 3 and evaporator 4 Agent, at this point, the entrance of the outlet connection of one end of heat-dissipating pipe 63 and expansion valve 3, the other end and compressor 1 connects, expansion valve 3 Outlet is equipped with throttle valve 8, and throttle valve 8 is preferably electromagnetic type, and throttle valve 8 is connect with the control system 5 of air-conditioning, convenient for passing through control The opening and closing of the control throttle valve 8 of system 5.The low-temperature low-pressure refrigerant flowed out from the outlet of expansion valve 3 part under the control of throttle valve 8 It is flowed into heat-dissipating pipe 63, and passes through from heat-dissipating pipe 63, therefore can be at the position that heat-dissipating pipe 63 is contacted with thermo-electric generation part 62 Low temperature is generated, the refrigerant flowed out from heat-dissipating pipe 63 is flowed into the entrance of compressor 1, since some refrigerant is in heat-dissipating pipe 63 Interior suction thermal expansion, compresses work done to it so as to reduce compressor 1.

Working principle: liquid refrigerant absorbs the heat of cooled space or object to be cooled in evaporator 4, is gasificated into The gas refrigerant of low-temp low-pressure is discharged into condenser after the sucking of compressor 1, being compressed into the gas refrigerant of high temperature and pressure 2, with air-cooled mode heat release in condenser 2, the hot wind blown out from condenser 2 after collecting warmware 61, collect by collection warmware 61 Certain heat, and there is refrigerant to flow through in heat-dissipating pipe 63, to form the temperature difference, thermo-electric generation part at the both ends of thermo-electric generation part 62 62 power generations, and will be in power storage to battery 7.It, can be in control system 5 after the electric energy of the inner accumulation of battery 7 reaches certain value It powers under control for the fan into air-conditioning.By the way that thermoelectric generator 6 is arranged, the partial heat discharged in condenser 2 is returned It receives, and is supplied to being used with electrical component for air-conditioning, while being heated so that compressor 1 by the refrigerant of thermoelectric generator 6 It tails off to its work done, therefore the refrigeration equipment of final the utility model can improve the Energy Efficiency Ratio of air-conditioning.
