Household air conditioner integrated control system and starting method thereof

Abstract

An integrated control system for a domestic air conditioner comprises at least two sets of interfaces in parallel used to connect with outdoor units (51, 52) and at least two sets of interfaces in parallel used to connect with indoor units (41, 42). The outdoor units (51, 52) and the indoor units (41, 42) are connected by the interfaces and pipelines so as to form a cooling medium circulation pipeline provided with a cooling medium distributor including an accumulator (13), an oil separator (14) and valves. An integrated controller controls and allocates the indoor units (41, 42), the outdoor units (51, 52) and the cooling medium distributor, and simultaneously controls the flow direction of the cooling medium in refrigerating and heating circulations, thereby making it possible that users can combine the indoor units and outdoor units freely. A startup method of the integrated control system for the domestic air conditioner is also disclosed.

Description

technical field [0001] The invention relates to a household air conditioner, in particular to an integrated control system of a household air conditioner and a starting method thereof. Background technique [0002] As a mature product, air conditioners have long been a part of people's lives, meeting people's needs for cooling or heating, and improving the comfort of people's lives. However, the existing household air conditioners need to be purchased as a complete set, so the cost of one-time investment is relatively high. [0003] The existing household air conditioners sold as a set are composed of indoor unit, outdoor unit and connecting pipelines. The manufacturer has designed the specifications before leaving the factory, and mixed use is not allowed. For example, 1 outdoor unit and 1 indoor unit are used together. , can not be used with 1 hp indoor unit and 3 hp outdoor unit. The independent space can be equipped with different existing air conditioners according to...

AI Technical Summary

Problems solved by technology

However, the refrigeration equipment is still a complete set of independent systems. When the environment changes or user needs change, the all-in-one machine still cannot be combined with other air conditioning systems to exert its energy efficiency.

[0009] In addition, due to the relatively small capacity of the existing household air conditioners, in order to ensure their compact structure, the overall design space is relatively small, so the corresponding compressors are relatively small, and such compressors cannot store more When using such compressors for parallel operation, there will be a series of problems, that is, the existing small-capacity compressor technology and air-conditioning technology cannot solve the problem of parallel operation of household air conditioners, because household small-capacity compressors When running in parallel, due to pressure deviation, the existing compressor without an oil equalization system will cause oil shortage and damage to the compressor with high pressure, so the existing household air conditioner cannot be simply connected in parallel to make it run normally
