Description

Technical Field

[0001] The invention belongs to the field of waste heat recovery, and in particular relates to a waste heat recovery and utilization device for air conditioning energy saving. Background Art

[0002] The refrigerant of the air conditioner is compressed into a high-temperature and high-pressure gas in a low-pressure state, and then enters the condenser through a pipe. In the condenser, the refrigerant releases heat and cools into a high-pressure liquid. The heat released by the refrigerant in the above process is discharged by the cooling fan of the air conditioner. The waste heat not only leads to greenhouse gas emissions, but also wastes precious thermal energy.

[0003] The invention patent with the existing patent number 201710452575.0 provides an air conditioning waste heat collection water supply system, including: a heat exchanger, which is arranged between the air conditioning compressor and the air conditioning condenser, and the heat exchanger includes from the inside to the outside: a first sleeve, a second sleeve, and a third sleeve; a water storage tank, the top of which is relatively provided with a third water inlet and a liquid flow hole, and the side wall near the bottom is provided with a third water outlet, and the water storage tank is provided with a liquid flow component, a first partition, a second partition, a turbine, and a water level sensor; a liquid storage box, which is arranged on the top of the water storage tank, including a liquid injection hole, A liquid flow tube is arranged at the bottom and passes through the liquid flow hole, and a gravity pressing component passes through the liquid storage box body, the gravity pressing component includes a gravity block, a connecting rod, a spring, and a plug body. When the water flow into the third water inlet stops, the gravity block presses the connecting rod to move downward to drive the plug body to be plugged into the liquid flow tube; in this technical solution, the speed at which the cold water flows through the first sleeve and the second sleeve of the outer circle of the refrigerant pipeline is relatively fast. Even if the first sleeve and the second sleeve inside the third sleeve are bent into a serpentine structure at the same time, the contact time between the water flow and the refrigerant pipeline is increased, and it is difficult for the water flow to absorb a large amount of heat released by the refrigerant.

[0004] Another invention patent with patent number 201710533304.8 also provides an air conditioning waste heat collection and water supply device, including an air conditioning condenser, which in turn includes a refrigerant circulation pipe and a heat sink arranged on the refrigerant circulation pipe, the refrigerant circulation pipe is wound into a coaxial vertical spiral with a gradually increasing spiral radius per turn, the cross-sectional edge profile of the refrigerant circulation pipe is petal-shaped, and the curves of the convex and concave parts are both parabolas, and sharp protruding particles are evenly arranged on the curved surface of the convex part of the inner wall of the refrigerant circulation pipe; a heat exchange water tank, which is coaxially sleeved on the periphery of the air conditioning condenser; a water storage tank, which is placed in a cool and ventilated place at the same height as the heat exchange water tank, and the bottom and the top are connected to the heat exchange water tank through pipes, and a water pump is also connected in series on the upper pipe connecting the two. In this technical solution, the refrigerant pipe is completely placed inside the heat exchange water tank, and the amount of water in the heat exchange water tank is large. Although the heat dissipated by the refrigerant pipe is fully utilized, the time for the cold water to heat up is long. When the amount of hot water is large, it is impossible to provide sufficient hot water in time. Summary of the invention
