Abstract

The invention relates to a method and a system for detecting faults in an HVAC system and a memorizer. The method comprises the steps that the indoor air temperature and the compressor equivalent running time in the HVAC system running period are obtained; the unit time changing rate of the indoor air temperature within the compressor equivalent running time is calculated; and according to changesof the unit time changing rate, whether faults happen to the HVAC system or not is judged. The method, the system and the memorizer can be used for carrying out online fault detection on the HVAC system, a series of faults can be effectively detected, alarms and other information can be output, and accordingly safety and the user satisfaction degree of the HVAC system can be better improved.

Description

technical field [0001] The present invention relates to the field of detection and control, and in particular to a method, system and memory for detecting faults in HVAC systems. Background technique [0002] HVAC (Heating, Ventilation and Air Conditioning, heating, ventilation and air conditioning) system has been widely used, it can bring great convenience and comfort to people's daily work and life. Since there are generally a large number of various components in the HVAC system, and especially after a long-term use, some failures (such as refrigerant leakage, compressor capacitor damage, etc.) are more likely to occur. Although the existing technology has provided many technical means to detect faults in the HVAC system, these existing detection means still have defects and deficiencies in aspects such as complexity, accuracy, convenience, and user experience. , can be further improved and optimized. Contents of the invention [0003] In view of this, the present in...
