Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
The utility model is described in further detail below with reference to specific embodiments and with reference to the attached drawings.
As shown in fig. 1, a novel multi-connected variable frequency air energy water heater comprises an outdoor unit 1 and an indoor unit 2, wherein the indoor unit 2 comprises at least two water tanks 21, an outlet of a compressor 11 of the outdoor unit 1 is connected with a first opening of a four-way valve 12, a second opening of the four-way valve 12 is connected with a heat exchanger refrigerant inlet 211 of each water tank 21, a heat exchanger refrigerant outlet 212 of each water tank 21 is connected with a fourth opening of the four-way valve 12 through an evaporator 13 of the outdoor unit 1, and a third opening of the four-way valve 12 is connected with an inlet of the compressor 11.
A high-voltage switch 14 is arranged between the compressor 11 and the first opening of the four-way valve 12.
The heat exchanger refrigerant outlet 212 of the water tank 21 is provided with a throttling element 213.
A temperature sensor 215 is arranged in the inner container 214 of the water tank 21.
The working principle of the utility model is as follows:
the refrigerant is processed by the compressor 11 to obtain high-temperature high-pressure gas, enters the four-way valve 12 from the first opening of the four-way valve 12, flows out from the second opening of the four-way valve 12, enters the heat exchanger in the water tank 21 from the heat exchanger refrigerant inlet 211 of the water tank 21, obtains high-pressure medium-temperature liquid after heat exchange in the water tank 21, flows out from the heat exchanger refrigerant outlet 212 of the water tank 21, becomes a low-temperature low-pressure gas-liquid mixture through the throttling element 213, enters the evaporator 13 of the outdoor unit 1 to evaporate and absorb heat to become gas, enters the four-way valve 12 from the fourth opening of the four-way valve 12, and finally flows out from the third opening of the four-way valve 12 to return to the compressor 11, so that the heating cycle is completed.
The control principle of the utility model is as follows:
as shown in fig. 1, which illustrates a schematic configuration in which one outdoor unit 1 is matched with 3 water tanks 21, when heating is performed, target water temperatures in the 3 water tanks 21 are all set to be T, and actual water temperatures in the 3 water tanks 21 are set to be T1, T2, and T3, respectively, and the control principle is as follows: when T1+ T2+ T3 < 1/2T, the compressor 11 operates at a high frequency according to PID, and when T1+ T2+ T3 is equal to or greater than 1/2T, the compressor 11 operates at a low frequency according to PID.
And the sectional variable frequency control is carried out according to the water temperature of the water tank 21, so that the aims of rapid heating and energy saving are fulfilled.
Finally, it should be noted that the above-mentioned list is only the specific embodiment of the present invention. Obviously, the present invention is not limited to the above embodiments, and many modifications are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the present invention are to be considered within the scope of the utility model.
