Methods and systems for determining dehumidifier performance
First Claim
1. A method of determining dehumidifier performance, the method comprising:
- determining a first humidity value of airflow entering the dehumidifier;
measuring an electrical current drawn by the dehumidifier;
using the measured electrical current, determining an efficiency of the dehumidifier;
based at least in part on the efficiency of the dehumidifier, determining a second humidity value of airflow exiting the dehumidifier; and
determining, with a processor, a difference between the first humidity value and the second humidity value.

Abstract
Methods, systems, and apparatuses directed to determining the performance of a dehumidifier are disclosed herein. A method of determining dehumidifier performance configured in accordance with one embodiment includes determining an inlet humidity value for airflow entering the dehumidifier, and determining an outlet humidity value for airflow exiting the dehumidifier. The outlet humidity value is determined based at least in part on an efficiency or correction factor for the dehumidifier. The method further includes comparing the inlet humidity value with the outlet humidity value to determine the amount of moisture that the dehumidifier is removing for the air.
