Abstract

The invention discloses an air-conditioning unit throttling control method and an air-conditioning unit. The air-conditioning unit comprises a compressor, a condenser, an evaporator, a throttling executive component and a throttling control unit. The throttling executive component is connected with a connecting pipeline of the condenser and the evaporator in series. The throttling executive component comprises a first throttling pipeline, a second throttling pipeline and a third throttling pipeline. An electronic expansion valve is arranged on the first throttling pipeline. A solenoid valve is arranged on the second throttling pipeline. A pore plate is arranged on the third throttling pipeline. The method comprises the steps of acquiring an actual detection value, comparing the actual detection value with a high set value and a low set value, and controlling the electronic expansion valve and the solenoid valve according to the comparison result. According to the air-conditioning unit throttling control method and the air-conditioning unit, the pore plate, the electronic expansion valve and the solenoid valve are connected in parallel, the opening degree of the electronic expansion valve is controlled, and on-off of the solenoid valve is controlled; the flow regulation control range is enlarged, the flow regulation capacity is improved, and the operation stability and safety of the unit are improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an air conditioning unit and a throttling control method of the air conditioning unit. Background technique [0002] For a large heat pump unit, because it includes two working conditions of cooling and heating, the flow rate of the refrigerant in the two working conditions is quite different, and the throttling area of ​​the orifice throttling usually used is not variable, resulting in the flow adjustment of the unit. Poor ability. Contents of the invention [0003] The invention provides an air-conditioning unit throttling control method and the air-conditioning unit, which solves the problem of poor flow regulation ability. [0004] In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions to achieve: [0005] A throttling control method for an air-conditioning unit, the air-condi...
