[0028] The technical solution of the utility model proposes a multifunctional combined power supply device.

[0029] Reference Figures 1 to 5 , in this embodiment, includes:

[0030] Shell 1;

[0031] A combined supply device is arranged in the housing 1, and includes a compressor, a hot water tank, a liquid storage tank, a dehumidification coil and an outdoor heat exchanger. The compressor, the hot water tank, the liquid storage tank, the dehumidification coil and the outdoor heat exchanger are connected to each other through a combined supply pipeline; the compressor is used to compress the refrigerant, the compressor is connected to the hot water tank, and a four-way valve is provided between the compressor and the hot water tank, the liquid storage tank and the outdoor heat exchanger are respectively connected to the hot water tank, the dehumidification coil is connected to the outdoor heat exchanger, and the dehumidification coil is used to dehumidify the air;

[0032] The control device is connected to the combined supply device, and the combined supply device and the four-way valve are both electrically connected to the control device.

[0033] Optionally, in this embodiment, the multifunctional combined supply device includes a shell 1, a combined supply device and a control device, wherein the combined supply device is arranged in the shell 1 to prevent the combined supply device from being disturbed by the external environment and causing the operating environment to be affected; the combined supply device includes a compressor, a hot water tank, a liquid storage tank, a dehumidification coil and an outdoor heat exchanger, wherein the compressor, the hot water tank, the liquid storage tank, the dehumidification coil and the outdoor heat exchanger are all connected through a combined supply pipeline, wherein the refrigerant is compressed into a high-temperature and high-pressure gas when passing through the compressor, and the compressor is connected to the hot water tank through the combined supply pipeline, and a four-way valve is provided between the hot water tank and the compressor. When hot water is needed, the four-way valve is opened, and the compressed refrigerant is heat exchanged with the hot water tank, and the required domestic hot water is obtained in the hot water tank. The liquid storage tank connected to the hot water tank is used to store and discharge excess liquid, and after the high-temperature and high-pressure refrigerant is heat exchanged with the hot water tank, it passes through throttling elements such as an expansion valve in the combined supply pipeline, and the refrigerant becomes a low-temperature and low-pressure liquid. When the refrigerant passes through the outdoor heat exchanger, it exchanges heat with the outside air. The refrigerant absorbs the heat in the air, which reduces the temperature of the air and achieves the effect of cooling. After the heat exchange, the refrigerant passes through the gas-liquid separator and flows back to the compressor for further compression to achieve reciprocating cycle refrigeration. When the room needs to be heated, the flow direction of the refrigerant in the combined supply pipeline is changed by a four-way valve or other switching device, so that the functions of the evaporator and the condenser are interchanged. The refrigerant flows through the compressor and is compressed into a high-temperature and high-pressure gas, and enters the indoor heat exchanger that originally serves as the evaporator. The refrigerant becomes a liquid state through heat dissipation, and the heat dissipated is transmitted to the outside to achieve the refrigeration function. At the same time, the dehumidification coil is connected to the outdoor heat exchanger, that is, the air after heat exchange passes through the dehumidification coil and is discharged to the outside, and the dehumidification coil has a dehumidification effect. The control device is connected to the combined supply device, and the opening and closing of the throttling element, the compressor, the four-way valve and other devices are controlled by the control device to meet people's needs. By jointly setting up the above-mentioned devices and components, the four functions of cooling, heating, dehumidification and hot water are combined into one device, which saves space and cost and is easy to operate. The excess heat generated during cooling and dehumidification can also be reused.

[0034] In this embodiment, the combined supply device includes an upper combined supply component and a lower combined supply component. Two sets of combined supply devices are set up to meet people's needs more quickly, and the upper combined supply component is a fluorine system for heat exchange, and the lower combined supply component is heat exchanged through a water system, wherein the fluorine system is a refrigerant (such as Freon) that circulates between the indoor and outdoor units to achieve heat transfer, and the refrigerant is running in the combined supply pipeline, and the refrigerant directly evaporates and absorbs heat in the indoor unit. The fluorine system has high heat transfer efficiency, but the air is relatively dry. The water system heat exchange is to provide air-conditioning cold / hot water, which is transported to the combined supply device by the water pipe system, and the water and air exchange heat at the indoor end. The heating or cooling speed is slow, but it is softer and the air is not easy to dry. Through the joint setting of the upper combined supply component and the lower combined supply component, users can choose different devices or use them together according to their needs.

[0035] In this embodiment, the upper supply assembly includes a first compressor 21, a first four-way valve 22, a second four-way valve 23, an upper hot water tank 24, an upper dehumidification coil 25, an upper liquid storage tank 26, a first outdoor heat exchanger 27 and a second outdoor heat exchanger 28, wherein the first outdoor heat exchanger 27 performs cooling, and the second outdoor heat exchanger 28 performs heating. When hot water is required, the first compressor 21 and the first four-way valve 22 are opened, and the compressed high-temperature and high-pressure refrigerant enters the upper hot water tank 24 for heat exchange to produce domestic hot water; when indoor cooling is required, the refrigerant after passing through the expansion valve enters the first outdoor heat exchanger 27 for heat exchange and cooling, and the upper dehumidification coil 25 dehumidifies the air; when heating is required, the first four-way valve 22 is closed, and the second four-way valve 23 is opened, and the compressed refrigerant enters the second outdoor heat exchanger 28 after passing through the throttling element, and the refrigerant dissipates heat and liquefies to achieve a heating effect.

[0036] In this embodiment, the upper joint supply component also includes a reheat coil, wherein the reheat coil includes a first reheat coil 31 and a second reheat coil 32, the first reheat coil 31 is connected to the first outdoor heat exchanger 27, and the second reheat coil 32 is connected to the second outdoor heat exchanger 28, wherein the reheat coil is mainly used to adjust the temperature and humidity of the air to meet specific air treatment requirements, but the reheat coil needs to consume a certain amount of energy for adjustment, so people can use it according to their needs, in other embodiments, a temperature monitor can also be added to the first outdoor heat exchanger 27 and the second outdoor heat exchanger 28 to facilitate real-time monitoring to achieve the required temperature, which is not limited here. Further, the upper joint supply component also includes a plurality of switch valves 33 arranged on the joint supply pipeline, and the opening and closing of the upper joint supply component is realized by the joint action of the plurality of switch valves 33 and the four-way valve.

[0037] In this embodiment, the lower joint supply assembly includes a second compressor 41, a third four-way valve 42, a lower liquid storage tank 43, a third outdoor heat exchanger 44 and a water system channel 45, wherein the second compressor 41 is connected to the third four-way valve 42, the second compressor 41 is used to compress the refrigerant, and through the third outdoor heat exchanger, heat is exchanged with the water source in the water system channel 45 to achieve the effect of cooling or heating, and the lower liquid storage tank 43 is used to store or discharge excess liquid. Further, in this embodiment, the lower joint supply assembly also includes a precooling coil 46, which is connected to the third outdoor heat exchanger 44, and is used to further adjust the temperature and humidity of the air, so that the temperature and humidity of the air entering the room are more suitable.

[0038] The above-mentioned embodiments only express the implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
