The tasks of air conditioning to remove heat and humidity can be considered as extracting heat from 25 ℃ environment to the outside and extracting moisture to the outside under the environment with dew point temperature of 16.6 ℃. The heat and moisture removal of the existing air conditioning mode is realized by cooling, condensing and dehumidifying air through an air cooler and sending the cooled and dried air into a room. The existing air conditioning mode of heat and humidity combined treatment has the following problems: the energy waste of the heat and humidity combined treatment. Because the condensation dehumidification method is adopted to remove indoor residual humidity, the temperature of a cold source needs to be lower than the dew point temperature of indoor air, the heat transfer temperature difference and the medium conveying temperature difference are considered, the 16.6 ℃ dew point temperature needs to be about 7 ℃ of the temperature of the cold source, and the reason that the existing air conditioning system adopts 5-7 ℃ of chilled water, and the refrigerant evaporation temperature of a direct evaporator in a room air conditioner is also 5 ℃ mostly. Because the temperature of the dehumidified air is low, the air can be sent out after being heated, the existing heating generally adopts a reheating condenser or an electric heater for heating, and because the temperatures of a refrigerant in the reheating condenser and the electric heater are high, the accurate control is difficult to realize. Therefore, improvements are needed.

The present invention will be further illustrated with reference to the accompanying drawings and specific examples, which are carried out on the premise of the technical solution of the present invention, and it should be understood that these examples are only for illustrating the present invention and are not intended to limit the scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides an energy transfer device, which includes a first heat exchanger 1, wherein a channel on one side of the first heat exchanger 1 is connected to a heat source, so as to introduce a heat medium into the channel on one side of the first heat exchanger 1, and the heat medium may be a high-temperature refrigerant compressed by a compressor, or may also be some hot waste products of a production plant, such as hot water and steam, so as to achieve heat recycling. The first heat exchanger 1 may be a plate heat exchanger, a shell-and-tube heat exchanger, a fin heat exchanger, a double-tube heat exchanger, or the like. The opposite side access connection of first heat exchanger 1 has circulation heat transfer system, and is specific, and circulation heat transfer system includes circulating pump 2, second heat exchanger 3 and tee bend proportion control valve 4, and wherein, circulating pump 2 can select as required decide circulating pump and frequency conversion circulating pump frequently. The inlet of the channel at one side of the second heat exchanger 3 is connected with the outlet of the channel at the other side of the first heat exchanger 1 through a pipeline, the outlet of the channel at one side of the second heat exchanger 3 is connected with the first inlet of the three-way proportional control valve 4 through a pipeline, the second inlet of the three-way proportional control valve 4 is connected between the first heat exchanger 1 and the second heat exchanger 3, the outlet of the three-way proportional control valve is connected with the inlet of the circulating pump 2, the pipeline, the first heat exchanger 1 and the second heat exchanger 3 are filled with refrigerating medium, and the refrigerating medium can adopt water, glycol, freon and the like according to actual needs. Furthermore, when the circulating pump 2 is started to operate, the refrigerant circularly flows between the first heat exchanger 1 and the second heat exchanger 3 through the pipeline, the heat medium heats the secondary refrigerant in the first heat exchanger 1, and the heated refrigerant enters the second heat exchanger 3 to heat the target medium, so that the heat of the heat medium is transferred to the target medium. The flow of the secondary refrigerant entering the second heat exchanger 3 can be controlled by controlling the opening ratio of the first inlet and the second inlet of the three-way proportional control valve 4, so that the temperature of the heated target medium can be adjusted, and the temperature of the heated secondary refrigerant is lower than that of the heat medium, so that the temperature of the heated target medium can be controlled accurately.
