Outdoor air conditioning unit, integrated air conditioning control system and starting method thereof

Abstract

The invention discloses an air conditioning system including an outdoor air conditioning unit, an integrated air conditioning control system and a starting method thereof which can be flexibly matched in utilization. The integrated air conditioning control system comprises at least two groups of parallelly connected ports for connecting outdoor air conditioning units and at least two groups of parallelly connected ports for connecting indoor air conditioning units, auxiliary ports are added on the outdoor air conditioning units, the outdoor units and the indoor units are connected via the ports, the auxiliary ports and pipelines to form a coolant circulating pipeline, a coolant distributor provided with a liquid reservoir, an oil separator and a valve is arranged in the coolant circulating pipeline, an integrated controller is utilized to control and adjust distribution of the outdoor units, the indoor units and the coolant distributor and to control flowing direction of refrigerating and heating coolant, and accordingly the outdoor units and the indoor units can be optionally combined by a user conveniently. The integrated air conditioning control system can be an independent product, can also be manufactured into a household air conditioning platform with a large expand space, and can be widely used in improvement of existing household air conditioners and manufacturing of new products.

Description

technical field [0001] The invention relates to an air conditioner product and an outdoor unit of an air conditioner, in particular to an outdoor unit of an air conditioner and its integrated control system and starting method. 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 diffe...

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
