Problems solved by technology

[0003] Existing central air conditioners generally use the method of matching the room with the air conditioner's external unit. When the room is opened, the corresponding external unit is turned on. It is impossible to effectively control the cooling capacity and wind speed of each room, and it is impossible to accurately control the temperature range and change of each room. The speed is high, the user experience is not good, and the total cooling capacity cannot be effectively used. There will be redundant cooling capacity and wind speed, and energy saving and emission reduction cannot be achieved.
[0004] In addition, the existing central air-conditioning pipelines are arranged too much. Once a pipeline is damaged, it is difficult to check and locate accurately.

Abstract

The invention discloses a method and a system for improving the refrigeration utilization efficiency and redundancy of an air conditioner. The method comprises the steps of collecting of room information in buildings, coding and database building of air conditioner pipelines and air outlets, determining of refrigerating capacity and air speed, and intelligent air conditioning services; and the system comprises an indoor air data collecting module, a pipeline data collecting module, a storage module, a pipeline coding and database building module, a refrigeration data processing module, an intelligent air conditioning service module and a communication module. According to the method and the system, the indoor temperature is controlled to reduce energy consumption to the maximum limit within the allowable range, refrigeration air-supplying states of all rooms are monitored and managed in real time, central air conditioner operation can be dynamically analyzed, a method for quick checking and positioning of abnormal conditions is provided, and the system is accurate and efficient and has the high practical value and wide application prospects.

Description

technical field [0001] The invention relates to the technical field of energy-saving control, in particular to a method and system for improving air-conditioning refrigeration utilization efficiency and redundancy. Background technique [0002] The central air-conditioning system consists of one or more cold and heat source systems and multiple air-conditioning systems. This system is different from traditional refrigerant-type air-conditioning systems (such as single-body units, VRV) to centrally process air to meet comfort requirements. The principle of liquid vaporization refrigeration is used to provide the required cooling capacity for the air conditioning system to offset the cooling load of the indoor environment; the heating system provides the required heat for the air conditioning system to offset the heat load of the indoor environment. The refrigeration system is a crucial part of the central air-conditioning system, and its type, operation mode, and structural f...
