Description

Technical Field

[0001] This utility model relates to the field of electrical technology, and in particular to a multi-functional integrated unit for air conditioning and hot water systems and fresh air heat pumps. Background Technology

[0002] Most existing air conditioning systems only have cooling and heating functions. During summer cooling, the outdoor unit discharges high-temperature air, which is often directly released into the environment without being effectively utilized, resulting in significant energy waste. This is especially problematic in specific scenarios like kitchens, where space is limited and large air conditioning units are unsuitable. Furthermore, cooking and cleaning in the kitchen require a large amount of hot water, but the high-temperature air discharged from the outdoor unit is not effectively used. If this high-temperature air could be used to heat water, it would not only meet the kitchen's hot water needs but also improve energy efficiency, achieve energy recycling, and reduce energy waste. Utility Model Content

[0003] The first aspect of this utility model provides a cooling and hot water system capable of switching between cooling mode and cooling and heating mode.

[0004] The second aspect of this utility model provides a small-sized air conditioning and hot water system that can be installed in cabinets in rooms such as kitchens.

[0005] To achieve the above objectives, the present invention adopts the following solution:

[0006] The first aspect of this utility model provides a cooling and air conditioning hot water system, including: a refrigerant unit and a hot water unit heated by the refrigerant unit. The refrigerant unit includes a compressor, a three-way valve, an indoor unit evaporator, a main unit condenser, a high-efficiency tank, and a gas-liquid separator. The refrigerant unit has a first working mode and a second working mode.

[0007] When the refrigerant unit is in the first working mode, the compressor, three-way valve, main unit condenser, indoor unit evaporator and gas-liquid separator form a circuit;

[0008] When the refrigerant unit is in the second working mode, the compressor, three-way valve, high-efficiency tank, indoor unit evaporator and gas-liquid separator form a circuit;

[0009] The hot water unit includes a water tank capable of storing water and a first heat exchange tube connected to the water tank. The first heat exchange tube is installed inside a high-efficiency tank. When the refrigerant unit is in the second working mode, the hot water unit can heat the water in the water tank through heat exchange in the high-efficiency tank.

[0010] The refrigerant unit also includes an electronic expansion valve. The three-way valve includes an A port, a B port, and a C port. The A port is connected to the compressor's exhaust port, the B port is connected to the inlet of the main unit's condenser, the C port is connected to the inlet of the high-efficiency tank, the inlet end of the electronic expansion valve is connected to the outlet of the main unit's condenser and the outlet of the high-efficiency tank, and the outlet end of the electronic expansion valve is connected to the inlet of the indoor unit's evaporator.

[0011] The refrigerant unit further includes a first one-way valve, which is located between the outlet of the main unit condenser and the inlet of the electronic expansion valve. The first operating mode is a refrigeration mode, wherein, in the refrigeration mode, the refrigerant of the compressor passes sequentially through the A and B ports of the three-way valve, the main unit condenser, the first one-way valve, the electronic expansion valve, the indoor unit evaporator, and the gas-liquid separator, and then flows back to the compressor through the return port.

[0012] The refrigerant unit also includes a second one-way valve, which is located between the outlet of the high-efficiency tank and the inlet of the electronic expansion valve. The second operating mode is a cooling and hot water mode. In the cooling and hot water mode, the refrigerant of the compressor passes sequentially through the A and C ports of the three-way valve, the high-efficiency tank, the second one-way valve, the electronic expansion valve, the indoor unit evaporator, and the gas-liquid separator, and then flows back to the compressor through the return port.

[0013] The first heat exchange tube is also equipped with a first circulating water pump. In the cooling and hot water mode, the first circulating water pump causes water in the water tank to flow into the first heat exchange tube, and the hot water after heat exchange in the first heat exchange tube flows back into the water tank.

[0014] The air conditioning hot water system also includes a heating unit, which includes a second heat exchange tube connected to a heat exchange plate and a second circulating water pump. In the cooling hot water mode, the second circulating water pump causes water from the water tank to flow into the second heat exchange tube, and the water after heat exchange in the second heat exchange tube flows back into the water tank.

[0015] The air conditioning and hot water system also includes a transport pipe that can be connected to a kitchen sink and bathing utensils, with the other end of the transport pipe connected to a water tank.

[0016] The refrigerant unit further includes a first filter and a second filter.

[0017] The second aspect of this utility model provides a new type of multi-functional integrated heat pump unit, including: a chassis, wherein the chassis is equipped with the air conditioning and hot water system as described above.

[0018] The water tank is set up independently, and the casing is also equipped with an indoor fan and an outdoor fan. The casing is also equipped with a filter screen, which is located in front of the air inlet of the indoor fan.

[0019] Compared with existing technologies, this utility model has the following advantages: When in use, this utility model uses a refrigerant unit for cooling. The refrigerant unit has two working modes. When only cooling is needed, the compressor, three-way valve, main unit condenser, indoor unit evaporator, and gas-liquid separator form a loop. The fan sends cold air into the room through the indoor unit evaporator. In this mode, only cooling is possible. When hot water and cooling are needed simultaneously, the flow path is switched by the three-way valve, so that the compressor, three-way valve, high-efficiency tank, indoor unit evaporator, and gas-liquid separator form a loop. The fan sends cold air into the room through the indoor unit evaporator. At the same time, when the refrigerant in the loop is in the high-efficiency tank, it conducts heat to the first heat exchange tube through heat exchange. The hot water in the second heat exchange tube continuously exchanges heat with the water in the water tank, thereby heating the water in the water tank. Attached Figure Description

[0026] The present invention will be further described in detail below with reference to embodiments:

[0027] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0028] like Figures 1 to 3 As shown, the first aspect of this utility model provides a cooling and air conditioning hot water system, including: a refrigerant unit 1 and a hot water unit 2 heated by the refrigerant unit 1. The refrigerant unit 1 includes a compressor 11, a three-way valve 12, an indoor unit evaporator 13, a main unit condenser 14, a high-efficiency tank 15, and a gas-liquid separator 16. The refrigerant unit 1 has a first operating mode and a second operating mode. When the refrigerant unit 1 is in the first operating mode, the compressor 11, the three-way valve 12, the main unit condenser 14, the indoor unit evaporator 13, and the gas-liquid separator 16... The liquid separator 16 forms a loop; when the refrigerant unit 1 is in the second working mode, the compressor 11, three-way valve 12, high-efficiency tank 15, indoor unit evaporator 13 and gas-liquid separator 16 form a loop; the hot water unit 2 includes a water tank 21 capable of storing water and a first heat exchange tube 22 connected to the water tank 21. The first heat exchange tube 22 is installed inside the high-efficiency tank 15, and when the refrigerant unit 1 is in the second working mode, the hot water unit 2 can heat the water in the water tank 21 through heat exchange in the high-efficiency tank 15.

[0029] In use, this invention utilizes a refrigerant unit 1 for cooling. The refrigerant unit 1 has two operating modes. When cooling is required only, the compressor 11, three-way valve 12, main unit condenser 14, indoor unit evaporator 13, and gas-liquid separator 16 form a circuit. The fan delivers cold air into the room through the indoor unit evaporator 13. In this mode, only cooling is possible. When hot water and cooling are needed simultaneously, the flow path is switched by the three-way valve 12, causing the compressor 11, three-way valve 12, high-efficiency tank 15, indoor unit evaporator 13, and gas-liquid separator 16 to form a circuit. The fan delivers cold air into the room through the indoor unit evaporator 13. Simultaneously, when the refrigerant in the circuit is in the high-efficiency tank 15, heat is transferred to the first heat exchange tube 22 through heat exchange. The hot water in the second heat exchange tube 22 continuously exchanges heat with the water in the water tank 21, thereby heating the water in the water tank 21.

[0030] The refrigerant unit 1 also includes an electronic expansion valve 17. The three-way valve 12 includes an A port, a B port, and a C port. The A port is connected to the discharge port of the compressor 11, the B port is connected to the inlet of the main unit condenser 14, and the C port is connected to the inlet of the high-efficiency refrigerant tank 15. The inlet end of the electronic expansion valve 17 is connected to the outlet of the main unit condenser 14 and the outlet of the high-efficiency refrigerant tank 15, and the outlet end of the electronic expansion valve 17 is connected to the inlet of the indoor unit evaporator 13. The electronic expansion valve 17 is used to throttle the refrigerant flowing out of the main unit condenser 14 and the high-efficiency refrigerant tank 14, thereby reducing the pressure.

[0031] The refrigerant unit 1 further includes a first one-way valve 18, which is located between the outlet of the main unit condenser 14 and the inlet of the electronic expansion valve 17. The air conditioning hot water system also includes a cooling mode, wherein, in the cooling mode, the refrigerant of the compressor 11 passes sequentially through the A and B ports of the three-way valve 12, the main unit condenser 14, the first one-way valve 18, the electronic expansion valve 17, the indoor unit evaporator 13, and the gas-liquid separator 16, and then flows back to the compressor 11 through the return port.

[0032] In cooling mode, compressor 11 compresses low-temperature, low-pressure gaseous refrigerant into high-temperature, high-pressure gaseous refrigerant. The high-temperature, high-pressure gaseous refrigerant flows out from the exhaust port of compressor 11 and enters the three-way valve 12. It then flows through the three-way valve 12 to the main unit condenser 14 for heat exchange. The heat exchanged is carried by the airflow into the ambient air, and the refrigerant undergoes a phase change and condenses into a liquid or gas-liquid two-phase refrigerant. At this time, the refrigerant changes from high temperature and high pressure to low temperature and high pressure. The liquid and gaseous refrigerants then enter the indoor unit evaporator 13 after passing through the first one-way valve 18 and the electronic expansion valve 17. The low-temperature refrigerant absorbs heat from the air around the indoor unit evaporator 13 after entering the indoor unit evaporator 13, causing the air temperature around the indoor unit evaporator 13 to drop. Cold air enters the room, and the refrigerant undergoes a phase change and most of it evaporates into low-temperature, low-pressure gaseous refrigerant. After passing through the gas-liquid separator 16, it flows back into compressor 11 from the return port, starting a new cooling cycle.

[0033] The refrigerant unit 1 also includes a second one-way valve 19, which is located between the outlet of the high-efficiency tank 15 and the inlet of the electronic expansion valve 17. The air conditioning hot water system also includes a cooling hot water mode. In the cooling hot water mode, the refrigerant of the compressor 11 passes through the A and C ports of the three-way valve 12, the high-efficiency tank 15, the second one-way valve 19, the electronic expansion valve 17, the indoor unit evaporator 13, and the gas-liquid separator 16 in sequence, and then flows back to the compressor 11 through the return port.

[0034] In the cooling / hot water mode, the compressor 11 compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant. The high-temperature, high-pressure gaseous refrigerant flows out from the exhaust port of the compressor 11 and enters the three-way valve 12. It then flows through the three-way valve 12 to the high-efficiency tank 15 for heat exchange. The heat exchanged is carried by the airflow into the ambient air, and the refrigerant undergoes a phase change and condenses into a liquid or gas-liquid two-phase refrigerant. At this time, the refrigerant changes from high temperature and high pressure to low temperature and high pressure. The liquid and gaseous refrigerants then enter the indoor unit evaporator 13 after passing through the second one-way valve 19 and the electronic expansion valve 17. The low-temperature refrigerant absorbs heat from the air around the indoor unit evaporator 13, causing the air temperature around the indoor unit evaporator 13 to drop. Cold air enters the room, and the refrigerant undergoes a phase change, with most of it evaporating into a low-temperature, low-pressure gaseous refrigerant. After passing through the gas-liquid separator 16, it flows back into the compressor 11 from the return port, starting a new cooling cycle. At this time, since the second heat exchange tube 22 is installed inside the high-efficiency tank 15, when the high-efficiency tank 15 is exchanging heat, the water in the second heat exchange tube 22 is heated, and the heat in the second heat exchange tube 22 is gradually transferred to the water tank 21 through heat conduction.

[0035] A first circulating water pump 23 is also installed on the first heat exchange tube 22. In the cooling and hot water mode, the first circulating water pump 23 causes water from the water tank 21 to flow into the first heat exchange tube 22, and the hot water after heat exchange in the first heat exchange tube 22 flows back into the water tank 21. The first circulating water pump 23 is located at the water inlet of the first heat exchange tube 22 to improve the heat exchange efficiency and quickly heat the water in the water tank.

[0036] The air conditioning hot water system also includes a heating unit 3, which includes a second heat exchange pipe 31. A heat exchange plate 32 is connected to the second heat exchange pipe 31, and a second circulating water pump 33 is also installed on the second heat exchange pipe 31. In the cooling / hot water mode, the second circulating water pump 33 causes water from the water tank 21 to flow into the second heat exchange pipe 31, and the water after heat exchange in the second heat exchange pipe 31 flows back into the water tank 21. When the second circulating water pump 33 starts, the hot water in the water tank 21 is sent by the second circulating water pump 33 through the second heat exchange pipe 31 to the heat exchange plate 32. The heat exchange plate 32 exchanges heat with the indoor air, thus heating the room.

[0037] At the same time, a temperature detection unit can be set at the water tank 21, and a constant temperature can be preset (such as 50℃, 55℃ or 60℃). When the temperature is lower than the constant temperature, the control unit is activated and the working mode is switched to heat the water in the water tank 21.

[0038] The air conditioning and hot water system also includes a transport pipe 4 that can be connected to the kitchen sink and bathing utensils. The transport pipe 4 is designed to facilitate domestic water use, ensuring that the faucets in the kitchen sink and bathing utensils maintain a hot water supply.

[0039] The refrigerant unit 1 further includes a first filter 1a and a second filter 1b. One end of the first filter 1a is connected to the outlet of the first one-way valve 18 and the outlet of the second one-way valve 19, and the other end of the first filter 1a is connected to the inlet of the electronic expansion valve 17. The second filter 1b is located at the outlet of the electronic expansion valve 17 and the inlet of the indoor unit evaporator 13. The first filter 1a and the second filter 1b can remove impurities from the refrigerant, ensuring smooth flow of the refrigerant in the system and reducing flow resistance.

[0040] like Figures 4 to 6 As shown, this utility model also provides a new type of multi-functional integrated heat pump unit, including: a casing 5, wherein the casing 5 is equipped with the air conditioning and hot water system described above. The integrated unit, achieved through the casing 5, can be placed inside a cabinet in the kitchen or other rooms, making full use of space.

[0041] The water tank 21 is independently set up and adopts a split design, which can be equipped with a larger capacity water tank to store more hot water. In this way, when the faucet of the kitchen sink or the shower appliance is turned on, hot water can flow out instantly without waiting.

[0042] Furthermore, the casing 5 is equipped with an indoor fan 6 and an outdoor fan 7. A filter 8 is also installed on the casing 5, located in front of the air inlet of the indoor fan 6. The indoor fan 6 blows cold air from the evaporator 13 of the indoor unit into the room, while the outdoor fan 7 blows hot air from the condenser 14 of the main unit to the outside. The filter 8 is installed on the casing 5 and is used to filter the air entering the indoor fan 6.

[0043] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
