Household air conditioner integrated control system and starting method thereof

Abstract

The invention discloses a household air conditioner integrated control system and a starting method thereof which are used for flexibly matching independent air conditioning systems. The household air conditioner integrated control system comprises at least two groups of parallelly connected ports for connecting outdoor units and at least two groups of parallelly connected ports for connecting indoor units, the outdoor units and the indoor units are connected via the 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 a user can optionally combine the outdoor units with the indoor units. The household air conditioner integrated control system can be an independent product, can also be manufactured into a household air conditioner platform with a large expand space, can be widely used in improvement of existing household air conditioners and manufacturing of new products, and has wide application prospect.

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, the air conditioner has already become a part of people's lives, meeting people's needs for cooling or heating, and improving people's comfort in life. However, because the existing household air conditioners need to be purchased in sets, the cost of one-time investment is relatively high. [0003] The existing household air conditioners sold in complete sets consist of indoor units, outdoor units and connecting pipes. The manufacturer has designed specifications before leaving the factory, and mixed use is not allowed. For example, a 1-hp outdoor unit is used in conjunction with a 1-hp indoor unit. , It cannot be used in conjunction with a 1-hp indoor machine and a 3-hp outdoor machine. The independent space can be equipped with different existing...

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
