Choosing condition based maintenance for split type air conditioner by considering the Energy Efficiency Ratio (EER)
MetadataShow full item record
This research was studied to determine the optimum value for condition based maintenance of split type air conditioner by measuring the temperature, humidity and flow of air through the fan coil unit. Measuring electric current and voltage of split type air conditioner. Find the energy efficiency ratio (EER) based on the actual use compared to the EER was determined by the manufacturer. To find the suitable maintenance and cleaning air conditioner for each. In conducting this research is split type air conditioner. Rated cooling 25,000 Btu/hr. Rated power 2,291 watts. Rated current 9.89 amperes. Rated voltage 220 volts single phase. Using the refrigerant R-22.EER 11.02Btu/hr/watts. Running 24 hour sperdayat a temperature of 18°C. Research indicates that the EER before maintenance is equal to6.23Btu/hr/watts. After maintenance is the EER of 20.2Btu/hr/watts or EER value, the increase was 69%. Thus preserving the EER of air conditioner. The condition based maintenance in reasonable time is one way that can help save energy.
