Abstract

The invention discloses a method for predicting abnormities of a central air conditioner. The method comprises the following steps: S1,monitoring whether refrigeration or heating of each room is abnormal or not, marking with a room abnormal factor; if yes, marking the room abnormal factor as 1, and if not, marking the room abnormal factor as 0, S2, calculating equipment abnormal factors F of all equipment in a cooling capacity or heat transfer pipeline of the central air conditioner, wherein F is equal to r / R, r represents the abnormal room number controlled by the equipment, and R represents the total room number controlled by the equipment, and S3, marking the equipment of which F is not smaller than n and not more than 1 as abnormal nodes to carry out manual detection and screening, wherein n is a predetermined value and n is more than o and not more than 1. A maintenance staff only needs to carry out detection when abnormal nodes in the equipment are found through the method, the detection number is less, and furthermore, the problem of energy waste caused by that the abnormalities are not found in time is solved.

Description

technical field

[0001] The invention relates to abnormal detection of air-conditioning equipment, in particular to a method for predicting abnormality of central air-conditioning. Background technique

[0002] Central air conditioners have been widely used in various large buildings. However, after several years of operation, due to lack of maintenance, many central air conditioners will produce equipment abnormalities, resulting in unsatisfactory cooling and heating effects, affecting user comfort, and wasting energy. . At present, the maintenance and testing of central air conditioners mainly rely on the traditional method: regular inspection and maintenance by air conditioner maintenance personnel, but due to the complexity of the installation and structure of central air conditioners, and the large number of air conditioner terminal fans, this method requires regular To check all air-conditioning equipment, including normal operation and abnormal operation, the detectio...
