| Research Abstract |
An operation problem has been investigated on a residential CO2heat pump water heating system as a novel technology with high efficiency and low environmental impact. Methods of predicting daily changes in system performance values and optimizing heat pump operating conditions have been developed so that they can apply to the on-line operation. The validity and effectiveness of the developed methods have been shown through the comparison between the system performance values predicted by the methods and calculated by a numerical simulation.
