Method for cleaning HVAC system and verifying cleaning effectiveness

摘要

A method of cleaning and a system and method of determining the effectiveness of a cleaning process for an HVAC system including a heat exchanger having a coil matrix. The coil matrix includes a plurality of rows of heat exchanging coils in which each adjacent row of coils is offset. The plurality of rows define channels extending through the coil matrix between an upstream side and a downstream side. The heat exchanger cleaning method includes applying a cleaning solution and a wet steam mixture directed into the channels. The effectiveness of the cleaning method is determine by a system and method which measures various operating parameters at the inlet side and outlet side of the heat exchanger both before and after the cleaning process. The system and method calculate a SEER rating using the total amount of heat removed by the HVAC system and the total power usage of the HVAC system.
