Pengaruh Beban Pendinginan Terhadap Temperatur Sistem Residential Air Conditioning Hibrida Dengan Kondensor Dummy Tipe Multi Helical Coil Menggunakan Refrigeran Hidrokarbon

Abstract

One way to save the energy is to improve the energy efficiency with combining two different equipments
become one new double-function or hybrid equipment. Hybrid air conditioning can improve energy efficiency by
removing waste heat to the environment through condenser for heating water. The objective of this experimental
study is to investigate the effect of cooling load to system temperature of vapor-compression cycle hybrid air
conditioning system with multi helical tipe of dummy condenser. The test was conducted with several cooling
load variations (0, 1000, 2000 and 3000 Watt) as residential cooling load simulation. The result showed that the
refrigerant temperature while using HCR-22 was obtained about 67.47 °C to 72.93 °C. The temperature of
refrigerant was increased as well as the applied cooling load to be increased. The temperature of refrigerant
had more heat which to be absorbed and released into the environment so that the produced water temperature
wasalso increased. Hot water temperature of the ACWH system using HCR-22 refrigerant was obtained about
41.01-44.96 ˚C.
