Air-conditioning system, control system and air-conditioning control method

Abstract

The invention discloses an air-conditioning system. The convenience in control operation for the air-conditioning system is improved. The air-conditioning system comprises M outdoor units, N indoor units and a control system; the M outdoor units are used for providing heat sources or cold sources, and the M is a positive integer; the N indoor units are used for receiving at least one heat source or cold source which is provided by one or more outdoor units, and the N is a positive integer; and the control system comprises a lubricating oil distribution subsystem, a refrigerant distribution subsystem and a control subsystem, the lubricating oil distribution subsystem is connected with the M outdoor units, the refrigerant distribution subsystem is connected with the M outdoor units, and the control subsystem is connected with the N indoor units, the M outdoor units, the lubricating oil distribution subsystem and the refrigerant distribution subsystem. The invention further discloses the control system and an air-conditioning control method.

Description

technical field [0001] The 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 is the air conditioner (room air conditioner), which is a unit used to provide a space area (generally closed) to deal with air temperature changes. Its function is to adjust the temperature, humidity, cleanliness and air flow rate of the air in the room (or closed space, area) to meet the requirements of human comfort or process. Conventionally, an air conditioner is known as a cooling device in which an indoor unit is connected to an outdoor unit through a refrigerant pipe. [0003] Air conditioners are divided into cold-only air conditioners and dual-purpose air conditioners for heating and cooling. The working principle is the same. The refrigerant generally used in air conditioners is Freon. The characteristic of Freon is that when...

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
