Abstract

The invention discloses an oil and gas balance controller of multi-connected air conditioner for the oil balance of compressors of at least two outdoor sets connected in parallel, wherein the oil balance controller comprises oil storage containers which communicate to the bottom of respective compressors of the plurality of outdoor sets, vent-pipes of respective compressors communicate to the oilstorage containers by an electromagnetic valve (1), every two oil storage containers communicate to one another by an oil balance connecting pipe to which each oil container communicates by an electromagnetic valve (4) and air suction pipes of respective compressors communicate by an electromagnetic valve (2), and each oil storage container communicates to the relative air suction pipes of respective compressors by an electromagnetic valve (3). The invention provides an oil and gas balance controller of multi-connected air conditioner for solving the problem of the oil balance of compressors in the various statuses.

Description

technical field [0001] The invention relates to air conditioner control, in particular to an oil balance and air balance control device for a multi-connected air conditioner. Background technique [0002] A multi-connected air conditioner is an air-conditioning unit in which multiple outdoor units are connected in parallel and multiple indoor units are connected in parallel. [0003] With the popularization and application of frequency conversion technology, the frequency conversion multi-connected air conditioning system has been developed rapidly. Compared with ordinary air conditioners, the frequency conversion multi-connected air conditioner system has the advantages of rapid cooling, heating, high efficiency and energy saving. Frequency conversion multi-connected air-conditioning system adapts to the needs of the market and meets the requirements of buildings of different scales with its free combination layout, excellent part-load efficiency and flexible use methods. ...
