Embodiment 1

[0028] An embodiment of the present invention provides an operation control method of an air conditioning unit.

[0029] figure 1 It is a flowchart of an operation control method of an air conditioning unit according to an embodiment of the present invention. Such as figure 1 As shown, the operation control method includes the following steps:

[0030] Step S102, when the air conditioning unit is powered on, the electronic expansion valve of the air conditioning unit is controlled to initialize.

[0031] In the technical solution provided by the above step S102 of the present invention, when the air conditioning unit is turned on and running, electronic expansion valves (Electronic Expansion Valves, EXV for short) of the air conditioning unit are controlled to initialize.

[0032] The air conditioning unit of this embodiment is provided with an electronic expansion valve, and the electronic expansion valve is used to replace the original subcooler of the air conditioning un...

Embodiment 2

[0066] The technical solution of the present invention will be described below in combination with preferred embodiments.

[0067] figure 2 It is a flow chart of another operation control method of an air conditioning unit according to an embodiment of the present invention. Such as figure 2 As shown, the method includes the following steps:

[0068] Step S201, determining the operating mode of the air conditioning unit.

[0069] The initial state of the air-conditioning unit is the shutdown state, the air-conditioning unit is started, the air-conditioning unit starts to run, and the operation mode of the air-conditioning unit is determined.

[0070] Step 202, cooling mode.

[0071] Make sure the operating mode of the air conditioning unit is cooling mode.

[0072] Step S203, the EXV of the external unit is fully opened, and the opening degree of the EXV of the internal unit is P 1 .

[0073] After it is determined that the operation mode of the air conditioner is the...

Embodiment 3

[0101] The embodiment of the invention also provides an operation control device for the air conditioning unit. It should be noted that the operation control device of the air conditioning unit in this embodiment can be used to implement the operation control method of the air conditioning unit in the embodiment of the present invention.

[0102] image 3 is a schematic diagram of an operation control device for an air conditioning unit according to an embodiment of the present invention. Such as image 3 As shown, the operation control device of the air conditioning unit includes: a first control unit 10 , a second control unit 20 , and a third control unit 30 .

[0103] The first control unit 10 is configured to control the electronic expansion valve of the air conditioning unit to initialize when the air conditioning unit is powered on.

[0104] The second control unit 20 is used to control the electronic expansion valve to establish a subcooling degree during initializa...

Abstract

The invention discloses an air conditioning unit and an operation control method and device thereof. The operation control method of the air conditioning unit includes: controlling an electronic expansion valve of the air conditioning unit to perform initialization while the air conditioning unit starts to operate; controlling the electronic expansion valve to establish a super-cooling degree in initialization; and controlling noise of the air conditioning unit according to the super-cooling degree. The operation control method can reduce the operation control cost of the air conditioning unit.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner unit and its operation control method and device. Background technique [0002] At present, when the multi-line system maintains a certain degree of subcooling, it is realized through a subcooler or a plate heat exchanger. For example, multi-connected systems with large cooling capacity rely on subcoolers or plate heat exchangers to maintain a certain degree of subcooling, thereby ensuring the noise problem during the operation of the air conditioning unit. [0003] However, relying on the subcooler or the plate heat exchanger to maintain a certain degree of subcooling will result in many system components, which in turn leads to the problem of high cost during the operation and control of the air conditioning unit. [0004] Aiming at the problem of high operation control cost of air-conditioning units in the prior art, no effective solution has been proposed y...
