The invention discloses an oil return control device, method and air conditioning system of an air conditioning system. The device comprises: a detection unit, which is configured to detect the lubricating oil separated by an oil separator (3) when the air conditioning system is running. State parameters; a control unit configured to control the operation process of the compressor (1), the oil return valve (2a) and the oil separator heater (3d) according to the state parameters of the lubricating oil separated by the oil separator (3) Take control. In this solution, by adjusting the operating states of the compressor and the air-conditioning system according to the state of the lubricating oil separated by the oil separator, it is beneficial to improve the reliability of the compressor and the air-conditioning system.
Description
technical field [0001] The invention belongs to the technical field of air conditioning systems, and in particular relates to an oil return control device and method of an air conditioning system and an air conditioning system. Background technique [0002] In the air-conditioning system composed of scroll compressors, an oil separator oil return component is provided, and the lubricating oil separated by the oil separator is returned to the compressor suction pipe through the oil return capillary under the action of the pressure difference, and communicates with the compressor. The gaseous refrigerant in the suction pipe is sucked into the pump body together to achieve the purpose of compressing the gaseous refrigerant and returning oil for lubrication. [0003] The working principle of the oil separator is to use the internal structure to separate the lubricating oil from the working medium gas by centrifugal force and gravity, but when the compressor exhaust contains liqu...
