Abstract:
This paper presents the experimental performance study to
observe the effect of changes in the cooling load of the combined
air conditioning and water heating system with trombone coil
type as dummy condenser using heat wasted from split type air
conditioner. Effects of the following parameters to the system
performance were examined: compressor power test chamber, test
chamber temperature, condenser temperature, hot water
temperature and Coefficient of Performance (COP). The results
showed that the bigger the cooling load is given in the test
chamber, the bigger the heat absorbed in the evaporator, so the
higher the temperature of the hot water in a tank. COP increased
with increasing of cooling loads. It was concluded that by
combined air conditioning and water heating system so that space
cooling and water heating can take place simultaneously, and the
energy performance can be raised considerably.
