Problems solved by technology

[0002] At present, most air conditioners on the market, such as compressor oil return control of multi-line equipment, adopt timing oil return control, that is, the compressor is controlled to return oil at a certain interval, and the oil return process may occur at night. When it is necessary to maintain a quiet environment during breaks or during user meetings, the unit will generate liquid flow sounds in the stopped internal unit when the unit is returning oil, and will reduce the outlet air temperature of the internal unit when the internal mechanism heats up, thereby affecting users. comfort of use

Abstract

The invention discloses a control method for a refrigerant circulation system. The control method comprises the following steps of adjusting the running parameters of the refrigerant circulation system according to the superheating degree and / or supercooling degree of the refrigerant circulation system in a first running mode, so that the oil discharge amount of the compressor in the period of thefirst running mode is reduced. In the control method for the refrigerant circulation system, the refrigerant circulation system has the first running mode of not carrying out oil return of the compressor, and in the running mode, the frequency of the compressor, the frequency of an outdoor fan, the opening degree of a throttle device, and other running parameters can be adjusted according to thesuperheating degree and / or supercooling degree of an indoor heat exchanger, so that the oil discharge amount of the compressor is reduced, and then carried oil at an indoor side is increased, and a reliable running oil amount for the compressor in the period of the running mode is ensured; and when a user needs to keep a quiet environment, a running module can be switched over to the first runningmode, so that the use comfort of the user is ensured.

Description

technical field [0001] The invention relates to the technical field of refrigerant circulation, in particular to a method for controlling a refrigerant circulation system. Background technique [0002] At present, most air conditioners on the market, such as compressor oil return control of multi-line equipment, adopt timing oil return control, that is, the compressor is controlled to return oil at a certain interval, and the oil return process may occur at night. When it is necessary to maintain a quiet environment during breaks or during user meetings, the unit will generate liquid flow sounds in the stopped internal unit when the unit is returning oil, and will reduce the outlet air temperature of the internal unit when the internal mechanism heats up, thereby affecting users. use comfort. Contents of the invention [0003] In view of this, one of the objectives of the present invention is to provide a control method for a refrigerant circulation system that can improv...
