The thermal pump type water heater which is superior in energy efficiency

摘要

It decides the thermal pump type hot water water heater system whose energy efficiency is high, whether or not you operate the thermal pump by translating one or reading value from many temperature sensors, on the basis of two thresholds. The thermal pump is operated, is stopped the temperature which is inspected being less than 1st threshold, when decreasing, in addition, the temperature which is inspected exceeding 2nd threshold, when rising. These thresholds two or correspond to the output of many sensors. Because temperature inspection talent of the device improves by utilizing plural temperature thresholds, until recently by comparison with the known device, improvement of energy efficiency becomes possible by the fact that operation of the thermal pump is adjusted by hot water request.
