Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically to an air conditioning waste heat recovery device. Background Technology

[0002] Air conditioners are important electrical appliances in people's lives. The heating and cooling processes of air conditioners are achieved through the circulation of refrigerant in the system and the transfer of heat.

[0003] Heating process: The refrigerant releases heat and liquefies in the condenser of the indoor unit, releasing heat into the room and raising the indoor temperature; it absorbs heat and vaporizes in the evaporator of the outdoor unit, absorbing heat from the outside.

[0004] During the cooling process, air conditioners transfer heat absorbed indoors to the outdoors through refrigerant circulation, and then dissipate the heat into the outdoor environment through the condenser. Therefore, the outdoor unit blows out hot air. When many air conditioners operate simultaneously, a large amount of heat is released into the outdoor environment; this heat is wasteful and harmful. It may lead to an increase in local ambient temperature, forming a "heat island effect."

[0005] Heat dissipation during heating: During heating, the air conditioner changes the refrigerant flow direction through a four-way valve, turning the outdoor unit into an evaporator and the indoor unit into a condenser. The refrigerant absorbs heat from the outside and transports it indoors, releasing heat through the indoor unit's condenser, thus raising the indoor temperature. At this time, the outdoor unit blows out cold air. Therefore, it is necessary to design an air conditioning waste heat recovery device to reduce the "heat island effect" in summer while recovering heat for hot water, thereby improving heat utilization efficiency.

[0026] Example:

[0027] like Figure 1 , Figure 2As shown, the air conditioning waste heat recovery device of this utility model includes an air conditioning outdoor unit 1 and a hot water tank 2. A heat exchanger 4 is wrapped around the exhaust pipe 3 of the air conditioning outdoor unit 1. A compressor is installed inside the air conditioning outdoor unit 1, and a reversing valve is installed between the compressor and the exhaust pipe 3. It also includes a heat exchange circulation pipe 5, which is provided with a first heat exchange section 6 that enters the heat exchanger 4 and a second heat exchange section that enters the hot water tank 2. The hot water tank 2 is positioned higher than the air conditioning outdoor unit 1. This utility model discloses an air conditioning waste heat recovery device. Through the cooperation of an outdoor unit 1, a hot water tank 2, an exhaust pipe 3, a heat exchanger 4, a heat exchange circulation pipe 5, a first heat exchange section 6, a second heat exchange section, and a micro circulation pump 7, when the outdoor unit 1 rotates and exhausts heat from the exhaust pipe 3, the heat from the exhaust pipe 3 is transferred to the heat exchanger 4. The micro circulation pump 7 causes the water in the heat exchange circulation pipe 5 to flow, continuously carrying the heat from the heat exchanger 4 to the hot water tank 4, heating the water in the hot water tank 4. This fully utilizes the air conditioning waste heat, reducing the "heat island effect" while recovering heat for hot water, thus improving heat utilization efficiency. Furthermore, the heat exchanger 4 can be installed on the reversing valve and the refrigerant pipe of the indoor unit. During winter heating, when the indoor heating is sufficient, waste heat can be used to heat water, reducing heat waste. It should be noted that water or oil can be added to the heat exchanger 4 to improve heat exchange efficiency, or a high-thermal-conductivity aluminum block can be used directly.

[0028] Figure 2 This is a schematic diagram of the air conditioning waste heat recovery device of this utility model. The electric valve and temperature control probe T are only functional in winter. When the temperature detected by the temperature control probe T is low, such as below 70°C, the electric valve is closed to ensure the normal operation of the indoor unit's heating function. When the temperature detected by the temperature control probe T is high, such as above 70°C, the electric valve is opened to initiate waste heat recovery, achieving the purpose of waste heat recovery in winter without affecting the normal operation of the indoor unit's heating function. Furthermore, the electric valve remains open in summer, continuously performing waste heat recovery during the summer months.

[0029] In a preferred embodiment, a miniature circulation pump 7 is provided on the heat exchange circulation pipe 5. This pump can provide a certain amount of power to help the heat exchange circulation pipe 5 to exchange heat quickly.

[0030] In a preferred embodiment, a first connecting hose 8, which communicates with the heat exchange circulation pipe 5, is provided at the water inlet end of the micro circulation pump 7, and a second connecting hose 9, which communicates with the heat exchange circulation pipe 5, is provided at the water outlet end.

[0031] In a preferred embodiment, a first manual valve 10 is provided on the heat exchange circulation pipe 5 near the heat exchange water tank 2. This design allows for convenient control of whether the heat exchange fluid flows in the heat exchange circulation pipe 5. When heat needs to be obtained to heat the heat exchange water tank 2, the first manual valve 10 is opened, and the micro circulation pump 7 is turned on, allowing the heat exchange fluid to flow and exchange heat.

[0032] In a preferred embodiment, a second manual valve 11 is provided on the heat exchange circulation pipe 5 near the outdoor unit 1 of the air conditioner. With this design, the second manual valve 11 can serve as a backup when the first manual valve 10 fails. Normally, the first manual valve 10 and the second manual valve 11 operate synchronously; if one fails, the other can serve as a backup.

[0033] In a preferred embodiment, a temperature-controlled solenoid valve 12 is provided between the second manual valve 11 and the second connecting hose 9. With this design, the switch can be controlled by sensing the temperature, making control quite convenient.

[0034] In a preferred embodiment, a check valve 13 is provided on the heat exchange circulation pipe 5 between the temperature control solenoid valve 12 and the second connecting hose 9. This design ensures that the heat exchange fluid in the heat exchange circulation pipe 5 can only circulate in one direction and will not flow in the opposite direction.

[0035] In a preferred embodiment, a filter 14 is provided on the heat exchange circulation pipe 5, located between the first connecting hose 8 and the first manual valve 10. This design allows for the continuous filtering of impurities in the heat exchange circulation pipe 5, ensuring consistently high heat exchange efficiency of the heat exchange fluid.
