Description

Technical Field

[0001] This invention relates to the field of heat pump air conditioning technology, and in particular to a heat control device and method for an energy-saving and environmentally friendly heat pump air conditioning system. Background Technology

[0002] Currently, in the use of heat pump air conditioners, heat pump water heaters are used to replace low-energy heating water from electricity and gas. However, this prevents the heat pump from being used as an air conditioner. The solution is to replace the fan and finned heat exchanger in the air-cooled condenser by installing evaporator coils and heat dissipation elements in the water tank. This allows the heat pump air conditioning system to both produce hot water and function as an air conditioner. The heat dissipation element is filled with a low-boiling-point medium. The end inserted into the water tank is the hot end, and the end passing through the brick wall is the cold end. When heated by hot water exceeding the upper limit of the condensation temperature, the low-boiling-point medium inside the hot end of the heat dissipation element boils and evaporates. The evaporated gas enters the cold end of the heat dissipation element, which is installed at a certain upward angle, and condenses. The condensed liquid returns to the hot end of the heat dissipation element by its own weight. The heat dissipation element operates in this cycle, transferring excess heat from the condenser side to the environment, thus ensuring the normal operation of the air conditioner.

[0003] In existing technologies, the hot end of the heat dissipation element absorbs heat from the water tank and then dissipates heat through low-boiling-point evaporation, relying on the cold end for heat dissipation; however, the excess heat of the condenser is directly transferred to the environment through the heat dissipation element, causing this part of the heat to be wasted and not fully utilized, and also leading to an increase in ambient temperature. Summary of the Invention

[0004] The purpose of this invention is to provide an energy-saving and environmentally friendly heat pump air conditioning system heat control device and method, which solves the problem that in the prior art, the hot end of the heat dissipation element absorbs heat from the water tank and then dissipates heat through low-boiling-point evaporation, relying on the cold end for heat dissipation; however, the excess heat of the condenser is directly transferred to the environment through the heat dissipation element, which results in the direct waste of this heat and its failure to be fully utilized, and also leads to an increase in the ambient temperature.

[0005] To achieve the above objectives, the present invention provides an energy-saving and environmentally friendly heat pump air conditioning system heat control device, including a water tank, an evaporator coil, a heat recovery box, a compressor, a compressor input pipe, a compressor output pipe, and energy-saving components. The water tank has an inlet pipe and an outlet pipe. The evaporator coil is placed inside the water tank. The heat recovery box is located above the water tank. The compressor input pipe and the compressor output pipe are both connected to both ends of the compressor. The end of the compressor output pipe away from the compressor is connected to the evaporator coil.

[0006] The energy-saving component includes multiple heat-absorbing units, a heat recovery box output pipe, and a first heat exchange shell. The multiple heat-absorbing units are respectively disposed in the water tank and the heat recovery box. The two ends of the heat recovery box output pipe are respectively connected to the heat recovery box and the first heat exchange shell. The first heat exchange shell is sleeved on the outside of the compressor input pipe.

[0007] The energy-saving component further includes a heat recovery box input pipe and a temporary storage box. The two ends of the heat recovery input pipe are respectively connected to the first heat exchange shell and the temporary storage box, and the temporary storage box is connected to the heat recovery box.

[0008] The heat absorption unit includes a heat absorption cylinder, a heat absorption copper plate, and multiple heat-conducting copper strips. One end of the heat absorption cylinder and the heat absorption copper plate is inserted into the water tank, and the other end of the heat absorption cylinder and the heat absorption copper plate is located inside the heat recovery box. The multiple heat-conducting copper strips are respectively disposed at both ends of the heat absorption copper plate.

[0009] The energy-saving component also includes a heat recovery heating unit, which is installed on the heat recovery box;

[0010] The heat recovery heating unit includes an air inlet pipe, an air outlet pipe, two first valve bodies, and two first fans. The air inlet pipe and the air outlet pipe are both connected to the top of the heat recovery box. The two first valve bodies and the two first fans are respectively located on the air inlet pipe and the air outlet pipe.

[0011] The energy-saving component also includes a water tank heat recovery unit, which is disposed on the water tank.

[0012] The water tank heat recovery unit includes a water tank output pipe, a second heat exchange shell, a water tank transfer pipe, a cooling shell, a cooling box, a water tank input pipe, and a cooling mechanism. The two ends of the water tank output pipe are respectively connected to the water tank and the second heat exchange shell. The second heat exchange shell is sleeved outside the compressor input pipe. The two ends of the water tank transfer pipe are respectively connected to the second heat exchange shell and the cooling box. The two ends of the water tank input pipe are respectively connected to the cooling box and the water tank. The cooling shell is sleeved outside the cooling box. The cooling mechanism is disposed on the cooling shell.

[0013] The cooling mechanism includes multiple second fans, two air outlet pipes, and two second valve bodies. The multiple second fans are sequentially arranged inside the cooling housing. Both air outlet pipes are connected to the cooling housing. The two second valve bodies are respectively arranged in the corresponding air outlet pipes.

[0014] This invention also provides a heat control method for an energy-saving and environmentally friendly heat pump air conditioning system, which uses the aforementioned energy-saving and environmentally friendly heat pump air conditioning system heat control device and includes the following steps:

[0015] During summer cooling, the compressor starts, and the refrigerant enters the compressor through the compressor input pipe. It is converted into a high-pressure, high-temperature refrigerant and reaches the evaporator coil through the compressor output pipe. At the same time, the evaporator coil is connected to the external evaporator. The evaporator returns to the compressor through the air conditioning system pipes and other components to complete the refrigeration cycle.

[0016] Water is added to the water tank through the inlet pipe;

[0017] When the heat pump air conditioner is turned on, the water in the water tank exchanges heat with the evaporator coil. After the water temperature rises, the heat absorption unit absorbs heat from the water in the water tank to cool it down.

[0018] The absorbed heat heats up the hot water in the heat recovery tank and stores the heat in the heat recovery tank. Then, the hot water from the heat recovery tank reaches the first heat exchange shell through the heat recovery tank output pipe. The hot water preheats the refrigerant medium that is about to enter the compressor and is located inside the compressor input pipe.

[0019] The preheated water returns to the heat recovery tank through the input pipe of the heat recovery tank;

[0020] Meanwhile, if heating is required in winter, water is temporarily stored in the temporary storage box. At this time, there is no water in the heat recovery box, only hot air.

[0021] Then, the first valve body is opened, the first fan is started, and the air outlet pipe is connected to the indoor environment, thereby inputting the hot air stored in the heat recovery box into the room and using the recovered heat for heating.

[0022] This invention discloses an energy-saving and environmentally friendly heat pump air conditioning system heat control device and method. The compressor starts, and the refrigerant enters the compressor through the compressor input pipe, transforming into a high-pressure, high-temperature refrigerant that reaches the evaporator coil through the compressor output pipe. Simultaneously, the evaporator coil connects to an external evaporator, which returns to the compressor through the air conditioning system's pipes and other components, completing the refrigeration cycle. Water is added to the water tank through the water inlet pipe. The heat pump air conditioner is then turned on. At this time, the water in the water tank exchanges heat with the evaporator coil, raising the water temperature. The heat absorption unit absorbs heat from the water in the water tank to lower its temperature. The absorbed heat heats the hot water in the heat recovery tank, storing the heat. The hot water from the heat recovery tank then reaches the first heat exchange shell through the heat recovery tank output pipe, preheating the refrigerant inside the compressor input pipe. Through this structural arrangement, heat is recovered and used to preheat the refrigerant before it enters the compressor, allowing the compressor to output a higher-pressure, higher-temperature refrigerant, fully utilizing the heat, avoiding waste of recovered heat, and ensuring the energy efficiency and stability of the air conditioning system.

Detailed Implementation

[0031] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0032] Please see Figures 1 to 5 This invention provides an energy-saving and environmentally friendly heat pump air conditioning system heat control device, including a water tank 1, an evaporator coil 2, a heat recovery box 3, a compressor 4, a compressor input pipe 5, a compressor output pipe 6, and an energy-saving component. The energy-saving component includes multiple heat absorption units, a heat recovery box output pipe 9, and a first heat exchange shell 10. The energy-saving component also includes a heat recovery box input pipe 11 and a temporary storage box 12. The heat absorption unit includes a heat absorption cylinder 13, a heat absorption copper plate 14, and multiple heat-conducting copper strips 15. The energy-saving component also includes a heat recovery heating unit, which includes an air inlet pipe 16, an air outlet pipe 17, two first valve bodies 18, and two first fans 19. The energy-saving component also includes a water tank 1 heat recovery unit, which includes a water tank output pipe 20, a second heat exchange shell 21, a water tank transfer pipe 22, a cooling shell 23, a cooling box 24, a water tank input pipe 25, and a cooling mechanism. The cooling mechanism includes multiple second fans 26, two air outlet pipes 27, and two second valve bodies 28.

[0033] The water tank 1 has an inlet pipe 7 and an outlet pipe 8. The evaporator coil 2 is placed inside the water tank 1. The heat recovery box 3 is located above the water tank 1. The compressor input pipe 5 and the compressor output pipe 6 are both connected to both ends of the compressor 4. The end of the compressor output pipe 6 away from the compressor 4 is connected to the evaporator coil 2. Multiple heat absorption units are respectively arranged in the water tank 1 and the heat recovery box 3. The two ends of the heat recovery box output pipe 9 are respectively connected to the heat recovery box 3 and the first heat exchange shell 10. The first heat exchange shell 10 is sleeved on the outside of the compressor input pipe 5. When the compressor 4 starts, the refrigerant enters the compressor 4 through the compressor input pipe 5, and is converted into a high-pressure, high-temperature refrigerant that reaches the evaporator coil 2 through the compressor output pipe 6. At the same time, the evaporator coil 2 is connected to an external evaporator, which returns to the compressor 4 through the air conditioning system's pipes and other components, completing the refrigeration cycle. Water is added to the water tank 1 through the water inlet pipe 7. The heat pump air conditioner starts operating, and at this time, the water in the water tank 1 exchanges heat with the evaporator coil 2. After the water temperature rises, the heat absorption unit absorbs heat and cools the water in the water tank 1. The absorbed heat heats the hot water in the heat recovery tank 3 and stores the heat in the heat recovery tank 3. Then, the hot water in the heat recovery tank 3 reaches the first heat exchange shell 10 through the heat recovery tank output pipe 9. The hot water preheats the refrigerant inside the compressor input pipe 5, thereby recovering the heat. This heat is then used to preheat the refrigerant before it enters the compressor 4, allowing the compressor 4 to output a high-pressure, high-temperature refrigerant, making full use of the heat, avoiding waste of recovered heat, and ensuring the energy consumption and stability of the air conditioning system.

[0034] Secondly, the two ends of the heat recovery input pipe are connected to the first heat exchange shell 10 and the temporary storage box 12, respectively, and the temporary storage box 12 is connected to the heat recovery box 3. The heat recovery input pipe can be used to transport the preheated water back to the heat recovery box 3. It passes through the temporary storage box 12 along the way. If it is necessary to temporarily store the water in the temporary storage box 12, the valve installed on the pipe can be activated to prevent water from entering the heat recovery box 3.

[0035] Simultaneously, one end of the heat-absorbing cylinder 13 and the heat-absorbing copper plate 14 is inserted into the water tank 1, and the other end of the heat-absorbing cylinder 13 and the heat-absorbing copper plate 14 is located inside the heat recovery box 3. Multiple heat-conducting copper strips 15 are respectively disposed at both ends of the heat-absorbing copper plate 14. The heat-absorbing cylinder 13 contains a low-boiling-point medium. When the water in the water tank 1 heats up, it boils the low-boiling-point medium in the heat-absorbing cylinder 13. The evaporated gas reaches the heat recovery box 3, then condenses and cools down, becoming liquid again and entering the water tank 1 to absorb heat. This cycle repeats continuously. Meanwhile, the heat-absorbing copper plate 14 and the heat-conducting copper strips 15 can directly absorb heat from the water tank 1, then conduct the heat to the heat recovery box 3, where it is further absorbed by the water.

[0036] In addition, the heat recovery heating unit is installed on the heat recovery box 3; the air inlet pipe 16 and the air outlet pipe 17 are both connected to the top of the heat recovery box 3, and the two first valve bodies 18 and the two first fans 19 are respectively installed on the air inlet pipe 16 and the air outlet pipe 17. During winter heating, water is first blocked outside the heat recovery box 3. At this time, the first valve body 18 is opened, the first fan 19 is started, air enters through the air inlet pipe 16, and air exits through the air outlet pipe 17, thereby discharging the heat stored in the heat recovery box 3. At the same time, the air outlet pipe 17 is connected to the indoor environment, thereby transporting heat into the room, thus using the recovered heat to heat the room.

[0037] Then, the heat recovery unit of the water tank 1 is installed on the water tank 1; the two ends of the water tank output pipe 20 are respectively connected to the water tank 1 and the second heat exchange shell 21, the second heat exchange shell 21 is sleeved on the outside of the compressor input pipe 5, the two ends of the water tank transfer pipe 22 are respectively connected to the second heat exchange shell 21 and the cooling box 24, the two ends of the water tank input pipe 25 are respectively connected to the cooling box 24 and the water tank 1, the cooling shell 23 is sleeved on the outside of the cooling box 24, and the cooling mechanism is installed on the cooling shell 23. The water tank output pipe 20 can output the hot water in the water tank 1 to the second heat exchange shell 21, which also preheats the refrigerant. Then, it passes through the water tank transfer pipe 22 to the cooling box 24. After the cooling mechanism cools the cooling box 24 and the water inside, it returns to the water tank 1 through the water tank input pipe 25 for continued use. The cooling shell 23 supports the cooling mechanism, thereby recovering and utilizing the heat in the water tank 1.

[0038] Finally, multiple second fans 26 are sequentially arranged inside the cooling housing 23, and both air outlet pipes 27 are connected to the cooling housing 23. Two second valve bodies 28 are respectively installed in the corresponding air outlet pipes 27. The two air outlet pipes 27 are connected to the outdoor environment and the indoor environment, respectively. When heating is required, the second fans 26 are activated, blowing air to cool the cooling box 24. The air heats up after passing through the cooling box 24 and is then discharged from the air outlet pipe 27 connected to the indoor environment, thus heating the indoor environment. If heating is not required, the air is discharged from the other air outlet pipe 27. This recovers and utilizes the heat generated during the cooling and heat dissipation of the hot water in the water tank 1.

[0039] When using the heat control device of the energy-saving and environmentally friendly heat pump air conditioning system of this embodiment, the compressor 4 starts, and the refrigerant enters the compressor 4 through the compressor input pipe 5, transforming into a high-pressure, high-temperature refrigerant that reaches the evaporator coil 2 through the compressor output pipe 6. Simultaneously, the evaporator coil 2 is connected to an external evaporator, which returns to the compressor 4 through the air conditioning system's pipes and other components, completing the refrigeration cycle. Water is added to the water tank 1 through the water inlet pipe 7. The heat pump air conditioner is turned on, and at this time, the water in the water tank 1 exchanges heat with the evaporator coil 2. After the water heats up, the heat absorption unit... The water in water tank 1 absorbs heat and cools down; the absorbed heat heats the hot water in heat recovery tank 3, and the heat is stored in heat recovery tank 3. Then, the hot water from heat recovery tank 3 reaches the first heat exchange shell 10 through the heat recovery tank output pipe 9. The hot water preheats the refrigerant inside the compressor input pipe 5. Through the above structural setup, heat is recovered and then used to preheat the refrigerant before it enters the compressor 4, so that the compressor 4 can better output high-pressure and high-temperature refrigerant, making full use of the heat, avoiding the waste of recovered heat, and ensuring the energy consumption and stability of the air conditioning system.

[0040] Please see Figure 6 The present invention also provides a heat control method for an energy-saving and environmentally friendly heat pump air conditioning system, comprising the following steps:

It is converted into a high-pressure and high-temperature refrigerant and reaches the evaporator coil 2 through the compressor output pipe 6. At the same time, the evaporator coil 2 is connected to the external evaporator. The evaporator returns to the compressor 4 through the air conditioning system pipes and other components to complete the refrigeration cycle.

[0042] S2: Add water to the water tank 1 through the water inlet pipe 7;

[0043] S3: The heat pump air conditioner is turned on and running. At this time, the water in the water tank 1 exchanges heat with the evaporator coil 2. After the water temperature rises, the heat absorption unit absorbs heat and cools the water in the water tank 1.

[0044] S4: The absorbed heat heats up the hot water in the heat recovery box 3 and stores the heat in the heat recovery box 3. Then the hot water in the heat recovery box 3 reaches the first heat exchange shell 10 through the heat recovery box output pipe 9. The hot water preheats the refrigerant medium that is about to enter the compressor 4 and is located inside the compressor input pipe 5.

[0045] S5: The preheated water returns to the heat recovery tank 3 through the heat recovery tank input pipe 11;

[0046] S6: At the same time, if heating is required in winter, water is temporarily stored in the temporary storage box 12. At this time, there is no water in the heat recovery box 3, only hot air.

[0047] S7: Then open the first valve body 18, start the first fan 19, connect the air outlet pipe 17 to the indoor environment, and then input the hot air stored in the heat recovery box 3 into the room to use the recovered heat for heating.

[0048] During summer cooling, the compressor 4 starts, and the refrigerant enters the compressor 4 through the compressor input pipe 5, transforming into a high-pressure, high-temperature refrigerant that reaches the evaporator coil 2 through the compressor output pipe 6. Simultaneously, the evaporator coil 2 connects to an external evaporator, which returns to the compressor 4 through the air conditioning system's pipes and other components, completing the cooling cycle. Water is added to the water tank 1 through the water inlet pipe 7. The heat pump air conditioner is then turned on, and the water in the water tank 1 exchanges heat with the evaporator coil 2. After the water temperature rises, the heat absorption unit absorbs heat from the water in the water tank 1 to cool it down. The absorbed heat heats the hot water in the heat recovery tank 3, storing the heat in the heat recovery tank 3. Inside, the hot water from the heat recovery tank 3 reaches the first heat exchange shell 10 through the heat recovery tank output pipe 9. The hot water preheats the refrigerant medium that is about to enter the compressor 4 and is located inside the compressor input pipe 5. The preheated water returns to the heat recovery tank 3 through the heat recovery tank input pipe 11. At the same time, if heating is needed in winter, the water is temporarily stored in the temporary storage box 12. At this time, there is no water in the heat recovery tank 3, only hot air. Then, the first valve body 18 is opened, the first fan 19 is started, and the air outlet pipe 17 is connected to the indoor environment, thereby inputting the hot air stored in the heat recovery tank 3 into the room to use the recovered heat for heating.
