Pengaruh Penggunaan Ice On Coil Pada Thermal Energy Storage Terhadap Efisiensi Energi Sistem Residential Air Conditioning Hibrida Sebagai Penyejuk Udara Ruangan Dan Pemanas Air/Pengering
Resindetial Air Conditioning Hybrid utilizes the cooling effect and simultaneous heating effect of the refrigeration machine. Chiller is a cooling system that uses cooling media (water or brine) and HCR-22 as a working fluid. There are 3 methods performed each with a coil and without coil. In Standby mode no average compressor cooling load is 1,1606 kW with an average COP of 2,451. While the standby mode of cooling load 1000 watt obtained the average working compressor 1.2680 kW with COP 2.471. Discharging mode without cooling load using coil, pump to circulate brine into coil located in TES to cold room obtained the average pump power of 0.1836 kW happened cooling saving for 180 minutes with energy efficiency 93,54%. While discharging mode of cooling load 1000 watt obtained work compressor power 02220 kW happened energy saving at TES for 90 minutes with energy efficiency 97,067%. For heat generated by the condenser can be used for heating / drying to maintain the working stability of the refrigeration system during cooling process takes place.
