Description

Technical Field

[0002] Against the backdrop of current energy shortages and increasingly urgent environmental protection needs, improving energy efficiency and reducing carbon emissions have become crucial directions for technological development. Traditional air-source heat pump devices, while providing air conditioning, often neglect the recovery and utilization of indoor waste heat, leading to a significant waste of usable energy. Especially during summer cooling, effectively recovering and using indoor waste heat for hot water heating would significantly improve overall energy utilization and reduce hot water supply costs. However, current technologies lack a device that can flexibly allocate waste heat for reuse and integrate air conditioning and hot water functions. Therefore, developing a heat recovery air-source heat pump device to achieve effective recovery and efficient utilization of natural energy is of great significance for alleviating energy pressure and promoting sustainable development.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Specific Implementation Example 1: Please see Figure 1 As shown, this utility model is a heat recovery air source heat pump device, including a compressor 1, an indoor heat exchanger 2, an outdoor heat exchanger 3, a water heater assembly 4, and a four-way valve 5. The first port of the four-way valve 5 is connected to the exhaust port of the compressor 1. The second port of the four-way valve 5 is connected to the intake port of the compressor 1. The third port of the four-way valve 5 is connected to both the indoor and outdoor heat exchangers 2 and 3. The fourth port of the four-way valve 5 is also connected to both the indoor and outdoor heat exchangers 2 and 3. The water heater assembly 4 includes a heat exchange branch pipe 6, a first shut-off valve 7, and a water heater heat exchanger 8. One end of the heat exchange branch pipe 6 is connected to the pipe between the four-way valve 5 and the outdoor heat exchanger 3. The other end of the heat exchange branch pipe 6 is connected to the pipe between the indoor heat exchanger 2 and the outdoor heat exchanger 3. The first shut-off valve 7 and the water heater heat exchanger 8 are respectively installed on the heat exchange branch pipe 6. A throttling regulating device 11 is installed on the section of pipe between the indoor heat exchanger 2 and the heat exchange branch pipe 6, between the indoor heat exchanger 2 and the outdoor heat exchanger 3. The throttling regulating device 11 is an electronic expansion valve. It also includes a temperature sensor used to sense the water temperature of the water heater assembly 4 and the indoor ambient temperature. This allows for timely monitoring of the hot water system temperature and the indoor temperature, facilitating adjustments to the air conditioning mode.

[0019] This heat recovery air source heat pump unit integrates a hot water system within the premise of an air conditioning system. When the indoor unit is cooling and the first shut-off valve 7 is open, the system effectively utilizes indoor heat for hot water heating during air conditioning operation. This not only improves energy efficiency and achieves effective recovery and utilization of natural energy, but also reduces the cost of hot water heating. It is suitable for the air conditioning and hot water needs of both residential and commercial locations. In practice, this design significantly reduces energy consumption and carbon emissions, saves users on electricity bills, and improves their quality of life. In commercial locations such as shopping malls and offices, this system can meet air conditioning and hot water needs while reducing dependence on the power grid, lowering operating costs, and improving economic efficiency.

[0020] To further improve the heating efficiency of the hot water system, a second shut-off valve 9 is installed on a section of pipe between the four-way valve 5 and the outdoor heat exchanger 3, located between the outdoor heat exchanger 3 and the heat exchange branch pipe 6. By closing the second shut-off valve 9 and simultaneously opening the first shut-off valve 7, all the waste heat transferred from the indoor unit is used to heat the water heater heat exchanger 8, meeting the demand for hot water in large quantities during the summer.

[0021] To facilitate the adjustment of waste heat involved in the hot water production of water heater assembly 4, water heater assembly 4 also includes a flow regulating valve 10. By adjusting the opening of the flow regulating valve 10, the waste heat involved in the heating of water heater assembly 4 can be precisely controlled, thereby meeting the hot water supply needs under different seasons and different water consumption demands. Specifically, in summer or during peak water consumption periods, the opening of the flow regulating valve 10 can be appropriately increased to increase the waste heat entering the water heater heat exchanger 8, thus meeting the demand for a large amount of hot water.
