    Experimental Study Of Split Air Conditioner With And Without Trombone Coil Condenser As Air Conditioning Water Heater
    (2016-04-14) Aziz, Azridjal; Satria, Arya Bhima; Mainil, Rahmat Iman
    This paper reports an experimental investigation of the performance split air conditioner (AC) with and without combined coil (trombone coil condenser) as heat pump water heater. The coil is a heat exchanger that is placed between the compressor and the condenser (main condenser) by utilizing the heat rejection. The coil is placed in an insulated water storage tank with a capacity of 50L. Data are captured every 5 minutes during the 120 minutes of testing, where the room temperature is maintained at temperatures of 20oC, 23oC and 27oC with variation of the cooling load at 1000W, 2000W and 3000W respectively.The results indicated that the use of coil increases the performance of air conditioner as an cooling air in room and water heater in reclamation tank simultaneously. The use of coil causes a slight increase in compressor power 0.014 kW (2%), where the COP increases around 12% higher than the increase in compressor power percentage, which is used as a water heater. Condenser temperature and room temperature with coil slightly rise compared to without coil at the cooling load increase. The finding indicates that the addition of the coil generates free hot water with temperature range around 61.54oC-64.33oC.The application of AC combined with water heater using coil does not affect the cooling performance but it can improve the energy performance considerably for cooling and energy saving for heating water

    Performance of Air Conditioning Water Heater with Trombone Coil Type as Dummy Condenser at Different Cooling Loads
    (2016-04-19) Aziz, Azridjal; Satria, Arya Bhima
    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.
