Abstract
A method for alerting component efficacy declining of HVAC apparatus includes: continually recording working time of a fan of an HVAC apparatus and controlling a pressure-difference transmitter arranged on both sides of a filter of the HVAC apparatus for calculating current pressure difference; calculating a first-stage slope based on a first pressure-difference condition, an initial pressure difference, and an accumulated working time of the fan when the current pressure difference reaches the first pressure-difference condition; calculating a second-stage slope based on a second pressure-difference condition, the first pressure-difference condition, and the accumulated working time of the fan when the current pressure difference reaches the second pressure-difference condition; predicting a remaining lifetime of the filter based on the first-stage slope if a comparison result between the two slopes is smaller than or equal to a threshold; otherwise, predicting the remaining lifetime of the filter based on the second-stage slope.
