Specific embodiment
Referring to attached drawing, a kind of air-conditioner waste heat recovery device, including sequentially connected compressor 1, condenser 2, expansion valve 3 and
Evaporator 4, these units form existing air-conditioning system, pass through three on the pipeline between the compressor 1 and the condenser 2
Logical 1 and 26 parallel connection of threeway be connected to heat exchanger 7, unidirectional electromagnetism is equipped between the threeway 1 and the heat exchanger 7
Valve 1 is equipped with Unidirectional solenoid valve 29, in the heat exchanger 7 and described three between the threeway 1 and the threeway 26
Check valve 10 is equipped between logical 29, the heat exchanger 7 includes heat exchange box 11 and the plate-fin set in the heat exchange box 11
Heat exchange unit 12, the heat exchange box 11 is interior to can control the Unidirectional solenoid valve 1 and the unidirectional electromagnetism equipped with middle control unit 13
Valve 29.The middle control unit 13 can control the Unidirectional solenoid valve 1 and 9 one of the Unidirectional solenoid valve to open one and close,
A circulation passage therein is opened, the check valve 10 is to avoid closing in the Unidirectional solenoid valve 8, the Unidirectional solenoid valve
During 9 opening, refrigerant enters in the heat exchanger 7, and the plate fin heat-exchanging unit 12 has the advantages that heat exchange area is big, can
Improve heat exchange efficiency.
The middle control unit 13 is connected with temperature sensor 14, and the temperature sensor 14 can pass through the middle control unit 13
The opening and closing of the Unidirectional solenoid valve 1 and the Unidirectional solenoid valve 26 are controlled, when the temperature sensor perceives institute
State the water temperature over-high in heat exchange box 11 be unfavorable for heat exchange when, can the Unidirectional solenoid valve be closed by the main control unit 13
One 8, the Unidirectional solenoid valve 29 is opened, air-conditioning carries out the cycle of the prior art at this time.
The middle control unit 13 is connected with liquid level sensor 15, and the liquid level sensor 15 can pass through the middle control unit 13
The heat exchange box 11 is controlled to intake and draining.
The heat exchange box 11 is equipped with inlet and outlet, the water inlet joining water box 16, the water outlet connection heat
Hydrophone 17 carries out constant temperature processing to carry out the hot water after heat exchange through the water heater 17.
Insulating layer is provided in the heat exchange box 11, hot water can be preserved for a long time.
As shown in the figure, the operation principle of the utility model is as follows：
Refrigerant becomes the liquid of high pressure-temperature after compressor 1, and temperature sensor 14 perceives the water in heat exchange box 11 at this time
Unit 13 is controlled after temperature is below setting value, in control and opens Unidirectional solenoid valve 8, closes Unidirectional solenoid valve 9, refrigerant will be from heat exchange
It circulates in device 7, after carrying out heat exchange in heat exchanger 7, the water temperature raising in heat exchange box 11, refrigerant temperature reduces, through unidirectional
Valve 10 flows into condenser 2, then flows into evaporator 4 after flowing through expansion valve 3 by pipeline, at this point, refrigerant becomes gas from liquid, into
Row heat absorption.Gaseous refrigerant becomes liquid under the action of compressor 1, repeats above procedure, feels until working as temperature sensor 14
When knowing that the water temperature in heat exchange box 11 is more than setting value, heat exchange efficiency is extremely low at this time, and middle control unit 13 will close Unidirectional solenoid valve
8, Unidirectional solenoid valve 9 is opened, run under the pattern of existing air conditioner circulating system at this time.When using the water in heat exchange box 11
Afterwards, after liquid level sensor 15 perceives liquid level below setting value, water in water tank 16 by under the control of middle control unit 13 from
Water inlet enters heat exchange box 11.Due to system at work, the water temperature in heat exchange box may not be constant, so heat exchange box 11
Interior water becomes thermostatted water through water heater 17.
