Abstract

Increasing the efficiency is one of methods to assist the Indonesian government’s planning in saving energy. One of them is to combine two functions from two different devices become a new device that have two functions. For instance, Split AC is used to cool the room. The adding of dummy condenser in Split AC is using heat exhaust at condenser that functioned as water heater. In this research, it is aimed to identify the effect of adding the dummy condenser toward cooler load. The method used in this research was design and experimental method. Based on the test, When cooler load was given to the room, the more the burden of cooling given, the higher refrigerant temperature to be thus heat water temperature was higher as well. During the operation 120 minutes, it obtained that heat water temperature was 84,110C and refrigerant temperature was 64,770C.Keywords : Dummy Condenser, Temperature, Cooler load and water valve faucet.

Abstract

The hybrid of Residential Air Conditioning (RAC) is a cooling system that utilizes cooling effect and warming effect of refrigeration simultaneously to improve machine performance. Chiller is one of cooling system that used to cool liquid (brine or water) by using HCR-22 refrigerant as the cooling medium and the brine serves as a secondary refrigerant to cooling the room indirectly. Standby mode is a cooling method without using ice or cooling methods from the chiller directly. In this study, the RAC with standby mode is done without cooling load so resulting in a performance with Coefficient of Performance average is 2.46, Factor of Performance average is 3.42, and Total of Performance average 5.88. Then, the average temperature of cooler room is 22.54 ˚C. The average temperature of warmer room is 38.87 ˚C was able to contribute both as warming and it can stability of refrigeration system during process.Keywords : Hybrids RAC, Chiller, Standby mode, Performance, Temperature

Abstract

In principle, the drying process involves the process of heat transfer and mass movement that occurs simultaneously. First, the heat must be transferred from the heating medium to the material. Furthermore, after water evaporation occurs, the moisture formed must be moved through the material structure to the surrounding medium. The purpose of this study is to determine the time required to dry bananas with water content that has been determined. The calculation analysis of consumption and energy cost for banana dryer system using heat pump. It is based on result oftheoritical calculations with closed air circle. The advantages of this study as development in the field of energy saving with refrigeration technology and air conditioning.From the experimental results and the analysis obtained the average temperature of dryer indoor that is 44,5oC and 47oC.Keywords: Drying, Temperature, Banana dryer system
