Air conditioning system, control system and air conditioning control method

Abstract

An air conditioning system, a control system, and an air conditioning control method. The air conditioning system comprises: M outdoor machines (101); N indoor machines (102); and a control system (103), comprising: a lubricating oil allocation subsystem (1031) connected to the M outdoor machines (101); a refrigerant allocation subsystem (1032) connected to the M outdoor machines (101); and a control subsystem (1033) connected to the N indoor machines (102), the M outdoor machines (101), the lubricating oil allocation subsystem (1031), and the refrigerant allocation subsystem (1032).

Description

Technical field [0001] The present invention relates to the technical field of air conditioning, in particular to an air conditioning system, a control system and an air conditioning control method. Background technique [0002] The air conditioner, or room air conditioner, is a unit used to process air temperature changes for a space area (generally closed). Its function is to adjust the temperature, humidity, cleanliness and air flow rate of the air in the room (or enclosed space, area) to meet the requirements of human comfort or technological process. Conventionally, an air conditioner as a refrigeration device is known, in which an indoor unit is connected to an outdoor unit through a refrigerant pipe. [0003] Air conditioners are divided into single-cold air conditioners and dual-purpose air conditioners. The working principle is the same. The refrigerant generally used in air conditioners is Freon. The characteristic of Freon is that when it changes from a gaseous state t...

Problems solved by technology

[0015] The embodiment of the present invention provides an air-conditioning system, a control system and an air-conditioning control method, which are used to solve the problem that the central air-conditioning in the prior art has a gas-liquid separator and an oil separator, and more pipelines need to be connected between them, so that The system connection is relatively complicated, and there are many components that need to be controlled during control. Therefore, there are technical problems such as low system reliability and high manufacturing cost. The number of separators is reduced, thereby reducing the number of connecting pipes and simplifying the process. The system structure reduces the control complexity, increases the convenience of control operation, reduces the technical effect of cost, and effectively improves the user experience
