Testing inverter type air conditioners for field performance.

Summary

Considerable technological advancement in domestic air conditioner (AC) designs over the past few decades has seen recent developments in variable-speed compressor (inverter) operation. Current test standards allow inverter AC (IAC) manufacturers to “lock” the compressor speed for a desired “rated” capacity. However, it is proposed that rating the inverter under “locked” mode is unrealistic, as it does not reflect the way inverters operate in real operation. In this study, an “unlocked” mode test method is discussed for testing IAC for “field” behaviour, and the results are compared to “locked” laboratory performance. For almost all inverter units tested, efficiency degradation was recorded in “unlocked” modes compared to when tested in “locked” mode for similar output capacity. It is suggested a new test method be considered for IAC unit performance in “unlocked” mode offering an alternative and more realistic field behaviour assessment.
