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

Abstract

The invention discloses an air-conditioning system. The reliability of the 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 supplying 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 and comprises a gas-liquid separator and an oil separator which are connected with each other by a first connecting pipeline, 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 parameters such as 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...

Problems solved by technology

[0015] Embodiments of the present invention provide an air-conditioning system, control system and air-conditioning control method, which are used to solve the problems in the prior art that the central air-conditioning system is complex and the one-to-one resource utilization rate of household split air-conditioning indoor and outdoor units is not high. The existing split air conditioners can be effectively integrated with minor changes or even no changes, completely breaking the one-to-one limitation of household split air conditioners, and only using fewer outdoor units to meet more indoor unit cooling / The heating demand not only simplifies the system structure, reduces the control complexity, but also improves the degree of intelligence and centralized control, improves the utilization rate of outdoor units, increases the convenience of control operation, and reduces the technical effect of cost, effectively Improved user experience
