Description

Technical Field

[0001] The utility model relates to the technical field of high-temperature heat pumps, and specifically relates to a dual-source combined high-temperature heat pump device. Background Technique

[0002] With the continuous growth of energy demand and the increasing prominence of environmental problems, the application of efficient and energy-saving heat conversion technologies in industrial and civil fields has received extensive attention.

[0003] Traditional heat pump devices usually rely on a single energy source, such as an air source or a water source. Their heat production efficiency is restricted by environmental conditions and energy supply. Due to factors such as changes in environmental temperature and the instability of a single energy source, it is often difficult to ensure stable and efficient heat production. In existing high-temperature heat pump devices, as a key component for heat transfer, the condenser has insufficient or unreasonable heat insulation measures, and part of the heat energy is dissipated into the surrounding environment without being effectively utilized during the transfer process, resulting in energy waste, increasing operating costs, and also restricting the application of heat pump devices in some scenarios with high requirements for heat production efficiency. For this reason, we propose a dual-source combined high-temperature heat pump device. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a dual-source combined high-temperature heat pump device to solve the problems raised in the above background technique.

A second heat exchange tube is installed inside the heat exchange box. A first connecting tube is connected between the evaporator and the heat exchange box. A second connecting tube is connected between the heat exchange box and the compressor. One ends of the first connecting tube and the second connecting tube are respectively connected to both ends of the second heat exchange tube.

[0006] A third connecting tube is installed at the output end of the compressor. One end of the third connecting tube is connected to the condensation box. A first heat exchange tube is installed inside the condensation box. One end of the third connecting tube penetrates through the condensation box and is connected to one end of the first heat exchange tube. The other end of the first heat exchange tube is connected with a return tube, and the return tube is connected to the evaporator. The condensation box is located inside the heat exchange box, and a first heat insulation sleeve is installed on the outside of the condensation box.

[0007] Preferably, a second heat insulation sleeve is installed on the outside of the heat exchange box.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. In this dual-source combined high-temperature heat pump device, when in use, the refrigerant first enters the evaporator.

The water in the inner cavity of the heat exchange box reheats the refrigerant in the second heat exchange pipe through the heat exchange fins and the second heat exchange pipe, achieving the effect of dual-source combined heating and improving the energy utilization rate of the high-temperature heat pump.

[0013] 2.

[0021] Please refer to Figures 1-4As shown in the figure, the present utility model provides a dual-source combined high-temperature heat pump device, which includes an evaporator 1, a heat exchange box 3, a compressor 5 and a condensation box 7. A second heat exchange tube 12 is installed in the inner cavity of the heat exchange box 3. A first connecting tube 2 is connected between the evaporator 1 and the heat exchange box 3. A second connecting tube 4 is connected between the heat exchange box 3 and the compressor 5. One ends of the first connecting tube 2 and the second connecting tube 4 are respectively connected to both ends of the second heat exchange tube 12;

[0022] A third connecting tube 6 is installed at the output end of the compressor 5. One end of the third connecting tube 6 is connected to the condensation box 7. A first heat exchange tube 10 is installed in the inner cavity of the condensation box 7. One end of the third connecting tube 6 penetrates through the condensation box 7 and is connected to one end of the first heat exchange tube 10. The other end of the first heat exchange tube 10 is connected with a return tube 9. A throttle valve is installed in the return tube 9. The return tube 9 is connected to the evaporator 1. The condensation box 7 is located inside the heat exchange box 3. A first heat insulation sleeve 8 is installed on the outside of the condensation box 7.

[0023] Specifically, when in use, the refrigerant first enters the evaporator 1. The evaporator 1 uses the air temperature for heating and inputs it into the inner cavity of the heat exchange box 3 through the first connecting tube 2. The water in the inner cavity of the heat exchange box 3 reheats the refrigerant in the second heat exchange tube 12 through the heat exchange fins 13 and the second heat exchange tube 12, achieving the effect of dual-source combined heating.

[0024] Among them: A second heat insulation sleeve 11 is installed on the outside of the heat exchange box 3. The second heat insulation sleeve 11 is used to insulate the heat exchange box 3.

[0025] Among them: A plurality of heat exchange fins 13 are installed on the outside of the second heat exchange tube 12. The heat exchange fins 13 are used to improve the heat exchange effect of the second heat exchange tube 12.

[0026] Among them: The inner side of the first heat insulation sleeve 8 abuts against the outside of the condensation box 7, and the outside of the first heat insulation sleeve 8 abuts against the inside of the heat exchange box 3. A small part of the heat energy dissipated by the condensation box 7 can be conducted to the heat exchange box 3, thereby effectively improving the energy utilization rate.

[0027] Working principle: The present utility model is a dual-source combined high-temperature heat pump device. When in use, the refrigerant first enters the evaporator 1. The evaporator 1 uses the air temperature for heating and inputs it into the inner cavity of the heat exchange box 3 through the first connecting tube 2. The water in the inner cavity of the heat exchange box 3 reheats the refrigerant in the second heat exchange tube 12 through the heat exchange fins 13 and the second heat exchange tube 12, achieving the effect of dual-source combined heating. The refrigerant enters the second connecting tube 4 through the second heat exchange tube 12 and is converted into a high-temperature and high-pressure refrigerant through the compressor 5. After leaving the compressor 5, it enters the first heat exchange tube 10 of the condensation box 7 through the third connecting tube 6. The first heat exchange tube 10 can exchange heat with the water in the condensation box 7, thereby completing the function of outputting high-temperature water. The heat-exchanged refrigerant leaves the first heat exchange tube 10, enters the return tube 9, and after passing through the throttle valve connected to the return tube 9, returns to the evaporator 1 for heating, thereby completing the refrigerant cycle;

[0028] During the process of heating the water in the condensation box 7, the first heat-insulating sleeve 8 effectively plays a heat-insulating role, avoiding the loss of heat energy into the air. The inner side of the first heat-insulating sleeve 8 is in contact with the condensation box 7, and the outer side of the first heat-insulating sleeve 8 is in contact with the inner side of the heat exchange box 3. A small part of the lost heat energy can be conducted to the heat exchange box 3 through the first heat-insulating sleeve 8 and has a heating effect on the water inside the heat exchange box 3, improving the energy utilization rate.
