Abstract

The invention discloses an oil balancing device. The oil balancing device comprises an oil separator, a first opening and a first valve, wherein the first opening is formed in the side face of the oil separator, the height between the first opening and the bottom of the oil separator is a first height, the first valve comprises a first end and a second end, the first end is connected with the first opening, the second end is connected with N outdoor units of M indoor units except for an Ith outdoor unit, and the N is a positive integer which is not larger than M-1. The oil separator receives lubricating oil exhausted by at least one outdoor unit of the N outdoor units through the first valve, when the height of the lubricating oil in the oil separator is higher than the first height, partial lubricating oil which is higher than the first height in the lubricating oil is led into at least one outdoor unit of the N outdoor units through the first valve, and the invention further discloses an air-conditioning system comprising the oil balancing device.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an oil equalizing device and an air conditioning system. Background technique [0002] An air conditioner is a unit used to provide a space area, especially a confined space area, to deal with air temperature changes. It can be used to adjust parameters such as air temperature, humidity, cleanliness, and air velocity in the space area. [0003] Among them, air conditioners can generally be divided into single air conditioners and central air conditioners. Among them, central air conditioners are mainly suitable for large places. Because they can achieve centralized control and have better operating effects compared with single air conditioners, they have gained more and more users. Welcome. [0004] Typically, a central air conditioner includes the following structures: [0005] At least one outdoor unit, and each outdoor unit (taking the i-th outdoor unit as an exampl...
