Abstract:
This thesis is a study on the use of chiller and split type air conditioning system in combination/ In the process study, a water chiller sized 1 ton, and a hydroric evaporator sized 1 ton will be installed with split type air conditioning in a household, A 1 phase inverter in used to de-frequency of electric current in air conditioning system. In lab test, frequency has been classified into 5levels which are 34.65 Hz, / 38.94 Hz, /44.1 Hz, / 47.5 Hz and 50 Hz. From the study, the frequency of electric current at 44.1 Hz has highest EER which equals to 12.42 Btu/W. It could be concluded that such frequency is the level that influences Freon flow, and working system of condenser and chiller. In addition, this level of frequency will make water chiller working at 72.44 % Effectiveness.
