[0042] This application provides a thermal energy utilization system. This system is installed in spaces prone to heat generation, such as kitchens. The system can lower indoor temperatures and utilize indoor heat to heat domestic or industrial water.

[0043] The heat utilization system in this application is installed in the kitchen to reduce the kitchen temperature and provide hot water supply.

[0044] Figure 1 This is a schematic diagram of a thermal energy utilization system provided in an embodiment of this application, such as... Figure 1 As shown, the heat energy utilization system includes a control device 1, a heat energy recovery unit, and a heat energy utilization unit. The heat energy recovery unit includes an air source heat pump 2 and a heat exchanger 3, with the air source heat pump 2 connected to the heat exchanger 3. The heat energy utilization unit includes a hot water tank 4, which is connected to the heat exchanger 3. The control device 1 is electrically connected to the air source heat pump 2 and is used to control the air source heat pump 2 to start the cooling mode and release heat to the heat exchanger 3.

[0045] In this embodiment, heat is absorbed by the air source heat pump 2 and transferred to the hot water tank 4 through the heat exchanger 3, thereby achieving the purpose of cooling, hot water supply and heat energy recovery and utilization, and reducing energy waste.

[0046] In this embodiment, the air source heat pump 2 includes an indoor heat pump unit and an outdoor heat pump unit. The indoor heat pump unit is installed inside the kitchen, and the outdoor heat pump unit is installed outside the kitchen. The indoor and outdoor heat pump units are connected by pipes. The outdoor heat pump unit is connected to a heat exchanger 3, and the heat generated by the air source heat pump 2 can be released into the heat exchanger 3.

[0047] In this embodiment, the indoor and outdoor units of the heat pump work together to achieve either a cooling or heating effect. In heating mode, the air source heat pump 2 absorbs heat energy from the outdoor air and then releases it into the room to provide heating. In cooling mode, the air source heat pump 2 absorbs heat energy from the room and then releases it to the outside to achieve a cooling effect.

[0048] In this embodiment, the purpose of reducing indoor temperature is achieved by using the cooling mode of the air source heat pump 2. Therefore, the purpose of each component in the air source heat pump 2 and the cooling principle of the air source heat pump 2 are explained here using the cooling mode of the air source heat pump 2.

[0049] In this embodiment, the air source heat pump 2 includes an evaporator, a compressor, a condenser, and an expansion valve. The evaporator is located in the indoor unit of the heat pump, the compressor and condenser are located in the outdoor unit, and the expansion valve is located in either the indoor or outdoor unit. In cooling mode, the evaporator absorbs heat and evaporates the liquid refrigerant into a gaseous refrigerant; the compressor compresses the gaseous refrigerant and converts it into a high-temperature, high-pressure gaseous refrigerant; the condenser converts the high-temperature, high-pressure gaseous refrigerant into a liquid refrigerant and releases heat to the heat exchanger 3; and the expansion valve controls the flow rate and pressure of the liquid refrigerant flowing from the outdoor unit to the indoor unit.

[0050] When the cooling mode is activated, the evaporator absorbs heat from the indoor air in the kitchen, causing the low-temperature, low-pressure refrigerant to evaporate, thus cooling the room. Then, the gaseous refrigerant enters the compressor. Through compression, the temperature and pressure of the gaseous refrigerant increase. Subsequently, the high-temperature, high-pressure refrigerant enters the condenser and is condensed into a liquid state, releasing heat to the heat exchanger 3. Finally, the liquid refrigerant enters the expansion valve, where its pressure and temperature decrease, and it then re-enters the evaporator, completing the cycle.

[0051] In some possible embodiments, the air source heat pump 2 includes a pressure sensor and a flow meter. The control device 1 is electrically connected to the pressure sensor and the flow meter. The pressure sensor measures the pressure of the liquid refrigerant and transmits the pressure data to the control device 1, while the flow meter measures the flow velocity of the liquid refrigerant and transmits the flow velocity data to the control device 1. The control device 1 adjusts the expansion valve in the air source heat pump 2 based on the acquired pressure and flow velocity data.

[0052] In some possible embodiments, the air source heat pump 2 is a variable frequency air source heat pump. The variable frequency air source heat pump 2 employs advanced variable frequency technology, enabling it to automatically adjust its operating frequency and power according to the actual needs of the indoor environment, achieving precise energy regulation. Compared to traditional fixed-frequency heat pump systems, the variable frequency air source heat pump 2 intelligently regulates its operation based on changes in indoor and outdoor temperatures, avoiding energy waste and thus achieving energy efficiency.

[0053] In this embodiment, the air source heat pump 2 automatically adjusts its operating state according to the set temperature to achieve optimal cooling. Compared to traditional air conditioners, the air source heat pump 2 consumes less electricity, achieves higher cooling efficiency, and reduces carbon emissions. Furthermore, the air source heat pump 2 operates with low noise, minimizing disruption to kitchen use.

[0054] In this embodiment, the heat exchanger 3 is installed inside the kitchen, near the kitchen's exhaust vent and stove. Heat generated by the stove during cooking is released into the heat exchanger 3, and heat generated by the air source heat pump 2 is also released into the heat exchanger 3. By placing the heat exchanger 3 near the stove and connected to the air source heat pump 2, heat recovery is achieved.

[0055] In some possible embodiments, in cooling mode, the outdoor unit of the heat pump releases heat to the heat exchanger 3; in heating mode, the indoor unit of the heat pump releases heat to the heat exchanger 3.

[0056] In this embodiment, the heat exchanger 3 is connected to the hot water tank 4. Heat collected by the heat exchanger 3 from the air source heat pump 2 or the air is transferred to the hot water tank 4, where the domestic water absorbs heat and its temperature rises. By setting up the hot water tank 4 connected to the heat exchanger 3, hot water can be provided to users, realizing the reuse of recovered heat energy and reducing energy waste.

[0057] In some possible embodiments, a temperature measuring device is installed inside the hot water tank 4, and the temperature measuring device is electrically connected to the control device 1. The temperature measuring device can measure the temperature of the water in the hot water tank 4 and transmit the water temperature value to the control device 1.

[0058] In some possible embodiments, a heating device is installed inside the hot water tank 4, and the heating device is electrically connected to the control device 1. The heating device uses water from the hot water tank 4. When the heat transferred to the hot water tank 4 by the heat exchanger 3 is insufficient to heat the domestic water in the hot water tank 4 to a preset temperature, the heating device in the hot water tank 4 can be activated by the control device 1, thereby heating the water to the preset temperature for user use.

[0059] In some possible embodiments, a level gauge is installed inside the hot water tank 4, and the level gauge is electrically connected to the control device 1. The level gauge can obtain the water level in the hot water tank 4 and transmit the water level to the control device 1. When the water level is lower than a first preset height, the control device 1 controls the water inlet device connected to the hot water tank 4 to replenish the hot water tank 4; when the water level is higher than a second preset height, the control device 1 controls the water inlet device connected to the hot water tank 4 to stop replenishing the hot water tank 4.

[0060] In this embodiment of the application, the heat collected by the heat exchanger 3 to heat domestic water has the following advantages: effectively utilizing kitchen waste heat, reducing energy waste, and improving energy efficiency; using waste heat to heat domestic water, reducing hot water costs; reducing dependence on fossil fuels, reducing carbon emissions, and making it more environmentally friendly and energy-saving.

[0061] In this embodiment, the thermal energy utilization unit includes a circulation pump. The two ends of the circulation pump are connected to a hot water tank 4 and a faucet, respectively, and the circulation pump is used to circulate hot water from the hot water tank 4 to the faucet. A control device 1 is electrically connected to the circulation pump and is used to regulate the operation of the circulation pump.

[0062] In some possible embodiments, the circulation pump can be connected to multiple faucets located in rooms such as kitchens and bathrooms via pipes.

[0063] In some possible embodiments, the user can activate the circulation pump via control device 1 when hot water is needed to obtain hot water. The user can also configure control device 1 to automatically activate the circulation pump when the hot water temperature in hot water tank 4 exceeds a preset temperature.

[0064] In this embodiment, the control device 1 is electrically connected to both the hot water tank 4 and the air source heat pump 2. The control device 1 sends a water temperature monitoring request to the hot water tank 4, and the hot water tank 4 returns the current water temperature data to the control device 1. The control device 1 sends a cooling command to the air source heat pump 2, which receives the command and begins cooling operation. During cooling, the air source heat pump 2 absorbs indoor heat, lowering the indoor temperature. The control device 1 continuously monitors the cooling status of the air source heat pump 2, which returns cooling status data to the control device 1. The control device 1 then adjusts the cooling operation of the air source heat pump 2 based on the received cooling status data. During cooling, the air source heat pump 2 transfers heat to the heat exchanger 3 while cooling the water. The heat exchanger 3 transfers the received heat to the hot water tank 4, raising the water temperature in the tank. If the water temperature in the hot water tank 4 is lower than the required temperature, the control device 1 sends a heating command to the tank. The hot water tank 4 receives the command and activates its heating device to heat the water.

[0065] Figure 2 This is a schematic diagram of the working process of a thermal energy utilization system provided in an embodiment of this application, such as... Figure 2As shown, the workflow of the heat energy utilization system is as follows: The user sets the desired temperature in the control device 1 according to their needs. When the desired temperature is lower than the actual indoor temperature, the control device 1 controls the air source heat pump 2 to start the cooling mode according to the set desired temperature. Under the action of the air source heat pump 2, the indoor temperature begins to decrease until it reaches the user's set desired temperature. At the same time, the heat generated by the air source heat pump 2 in the cooling mode is transferred to the heat exchanger 3. The heat exchanger 3 transfers the received heat to the hot water tank 4, and the water in the hot water tank 4 absorbs heat and its temperature rises. When the control device 1 controls the circulation pump to start, the circulation pump can transport the hot water in the hot water tank 4 to the faucet through pipes. The user can then obtain hot water by turning on the faucet. The control device 1 can automatically adjust the operation of the air source heat pump 2 by monitoring the indoor temperature and the pressure and flow rate of the refrigerant in the air source heat pump 2. Through the above workflow, the heat energy utilization system can achieve optimal cooling effect and hot water supply.

[0066] In this embodiment, a modular design is adopted, with components such as the air source heat pump 2, heat exchanger 3, and hot water tank 4 installed independently. This modular design simplifies the installation process, allowing users to either seek professional assistance or install the components themselves. Furthermore, the independent installation of each component facilitates regular maintenance and upkeep.
