Embodiment 1
[0027] In preferred embodiment 1 of the present invention, an air conditioning unit is provided, specifically, figure 1 An optional structural block diagram showing the air conditioning unit, such as figure 1 As shown, the unit includes: a compressor, a condenser, and an evaporator, wherein: the evaporator includes: a falling film heat exchange area and a flooded heat exchange area; it also includes: a first throttling passage, one end of which is connected to the condenser , the other end is connected to the falling film heat exchange area, which is used to control the flow of refrigerant entering the falling film heat exchange area; the second throttling passage is connected to the condenser at one end and the flooded heat exchange area at the other end, and is used to It is used to control the flow of refrigerant entering the flooded heat exchange area.
[0028] In the above embodiment, an air conditioning unit is provided, wherein the evaporator of the unit includes a fal...
Embodiment 2
[0041] Based on the air-conditioning unit provided in the above-mentioned embodiment 1, a control method of the air-conditioning unit is also provided in the preferred embodiment 2 of the present invention. This control method can be directly applied to various air-conditioning units, and can also be applied to On other devices with some functions of the unit, when it is specifically realized, it can be realized by installing software, APP on the air conditioning unit or other devices, or writing the corresponding program of the controller of the air conditioning unit or other devices. Specifically, image 3 An alternative flowchart showing the method, such as image 3 As shown, the method includes the following steps S302-S306:
[0042] S302: According to the load demand of the unit, determine the flow rate of the refrigerant entering the heat exchange zone in the down mode;
[0043] S304: Determine whether the refrigerant flow rate in the falling film heat exchange zone me...
Embodiment 3
[0054] Based on the air-conditioning unit control method provided in the above-mentioned embodiment 2, a computer device is also provided in the preferred embodiment 3 of the present invention, including a memory, a processor, and a computer program stored in the memory and operable on the processor , when the processor executes the program, the above-mentioned air conditioning unit control method is realized.
[0055] In the above embodiment, a method for controlling the air conditioning unit is provided. According to the load demand of the unit, the refrigerant flow rate entering the falling mode heat exchange zone is determined, and it is judged whether the refrigerant flow rate in the falling film heat exchange zone meets the load demand. When the refrigerant flow rate in the membrane heat exchange area does not meet the load demand, determine the refrigerant flow rate entering the flooded heat exchange area to meet the load demand. Through the two replenishment channels, ...
