Multiple-compressor parallel wind cooling module air conditioner system

Abstract

The invention particularly relates to an air conditioning system provided with an air-cooled module and multiple compressors connected in parallel, which comprises a plurality of groups of compressor units connected in parallel and is characterized in that: each group of compressor unit consists of an independent working system which is composed of a compressor, a condenser, oil content, gas content, a four-way directional control valve, a thermal expansion valve and other common components; all compressors are communicated through oil balancing pipes and all groups of compressor units, after being collected in parallel, gather at a gas distributor and a high pressure liquid storage device and are connected with the outside of the room in a form of one gas main and one liquid main. After adopting the technical proposal, as all compressor units are in an independent working state and only gather at the gas distributor and the high pressure liquid storage device, the equal distribution of a cryogen among all compressor systems can be ensured to the utmost extent and the balancing working of the system ensures maximum balancing oil return among the compressors and effectively solves the problem of uneven oil return in a dual-compressor parallel technique.

Description

Technical field: [0001] The invention relates to the technical field of air conditioners, in particular to a multi-compressor parallel air-cooled module air conditioning system. Background technique: [0002] The parallel multi-compressor unit in the prior art adopts a design scheme in which multiple groups of compressor units share one system (condenser, oil separator, gas separator, thermal expansion valve and other parts share), for example, the patent No. 2004200736888 invention patent "one A variety of multi-compressor parallel frequency conversion multi-unit central air conditioners" adopt a unified working system (after the compressor is exhausted, the exhaust pipe, oil separator, thermal expansion valve, condenser, liquid accumulation pipe and other components are not independent, and a single Integral components. This kind of structure generally has the problem of uneven oil return from the compressor during use, which eventually leads to the problem of compressor b...

Problems solved by technology

[0005] After adopting the above technical solution, since each compressor unit is in an independent working state, it is only collected at the gas distributor and high-pressure liquid receiver, so it can ensure the average distribution of refrigerant between each compressor system and the system balance work, so that the oil return can be balanced to the maximum among the compressors, effectively solving the problem of uneven oil return in the parallel connection technology of dual compressors
