Determining air filter replacement conditions using air flow and energy consumption values

摘要

A method of determining a condition of a filter located within a system is provided. The method may include determining a first air flow measurement value for a first air flow through the filter, determining a first energy consumption value associated with generating the first air flow through the filter, determining a first ratio between the first air flow measurement value and the first energy consumption value, determining a second air flow measurement value for a second air flow through the filter, determining a second energy consumption value associated with generating the second air flow through the filter, and determining a second ratio between the second air flow measurement value and the second energy consumption value. The filter may then be replaced based on a comparison between the determined first and the determined second ratio.

1. A method of determining a condition of a filter located within a system, the method comprising:
determining a first air flow measurement value for a first air flow through the filter; determining a first energy consumption value associated with generating the first air flow through the filter; determining a first ratio between the first air flow measurement value and the first energy consumption value; determining a second air flow measurement value for a second air flow through the filter; determining a second energy consumption value associated with generating the second air flow through the filter; determining a second ratio between the second air flow measurement value and the second energy consumption value; and replacing the filter based on a comparison between the determined first and the determined second ratio.
