Abstract

Solar energy is one source of energy that has an unlimited amount, making it the largest source of energy reserves on earth. The utilization of the commonly used is radiation energy in a solar drying apparatus. A solar type solar dryer cabinet is a direct heating type solar dryer that utilizes natural convection to heat a cabin shaped air. The cabinet dryer consists of a solar collector and an integrated drying chamber. The research methodology used in this study is an experimental method to determine the performance of two types of solar dryer type cabinet. One of the cabinet type solar powered dryer uses sensible heat storage in the form of a split stone. Thermal energy storage or heat is a system that storage heat from surrounding. The heat energy storage system is divided into two, namely sensible calorie storage system and latent heat storage system. The average temperature of a banana on a solar power dryer with a heat storage medium is 39oc with the highest temperature on the second shelf is 52.7oc while the banana temperature on the solar power dryer without heat storage medium is 37oc and the highest temperature on the second shelf is 51.7oc. The final water content contained in the banana after drying on the dryer with the heat storage medium is 36% and in drying apparatus without a heat storage medium is 45.2% . The efficiency of the test using a solar power dryer with a heat storage medium is obtained 28.4%, while for testing using a solar power dryer without heat storage media that is equal to 26.1%.Keywords: Solar dryer, Sensible Heat storage, Split stone

Abstract

Factors that also affect performance and reduce exhaust gas emissions are fuel quality combustion in the combustion chamber. One of the parameters that influence is the amount of supply of combustion air into the combustion chamber. Where this supply is governed by the camshaft mechanism through open-close of the intake valve and the exhaust valve. The purpose of this study is to determine the effect of reduction of lift camshaft on engine performance. The investigation was conducted on a Yamaha jupiter Z1 single-cylinder, four-stroke, spark ignition engine. The experiments were performed by varying the reduction of lift camshaft, with camshaft standard (CAM STD), camshaft condition 1 with reduction of lift camshaft 0.5 mm (CAM 1), camshaft condition 2 with reduction of lift camshaft 0.10 mm (CAM 2) and camshaft condition 3 with reduction of lift camshaft 0.15 mm (CAM 3) and speed of the engine (2000 rpm, 3000 rpm and 4000 rpm). As a result, the maximum effective braking power was on CAM STD, at the engine speed of 3000 rpm that was 535.072 Watt, minimum SFC (Specific Fuel Consumption) was on CAM 2, at the engine speed 3000 rpm that was 1.54 x 10-7 kg/J and the thermal of maximum braking efficiency was on the CAM 2, at the engine speed of 3000 rpm equal to 14.129%.Keywords: Performance, Internal Combustion Engine, Camshaft

Abstract

Portable coolers and heaters use thermoelectric modules with an additional heat pipe as a heat transfer median. This research is to know the cooling temperature that can be achieved by the utilization of thermoelectric heat exhaust as heater with 6 volt input voltage. The effect of heat pipe usage on cooling and heating temperatures is also observed. In this study the use of heat pipe provides a better cooling effect where the temperature is lower than the test without heat pipes for 50 minutes. Achievement of cooling and heating chamber under non-heat-free heat pipe 23.41 oC and 32.36 oC, whereas by using heat pipe the achievement of cooling and heating chamber reaches 22.83 oC and 30.52 oC.

Abstract

Air Conditioning (AC) machines with standard vapor-compression cycle has higher energy consumption, because the condenser is directly cooled by outside air. The condensate from evaporator has a temperature around 10-15°C. This study is determined the potential of evaporative cooling by using the condensate as a cooling medium for the condenser of incoming air cooler. This study used experimental method by testing of the effect of water condensate usage with the performance of standard of vapor compression cycle. The results showed that the using of Evaporative Cooling (EC) can reduce the incoming air into the condenser with an average temperature of 29.14 ° C (without cooling load) and 30.96 ° C (with 2000 W of cooling load). Then, the average working of the compressor without cooling load, before using EC was 0.60 kW and after using EC of 0.55 kW. A given cooling load of 2000 W was revealed an average working of compressor of 0.63 kW (without EC) and 0.59 kW (with EC). The compressor works decreased due to the using of an evaporative cooler.Keywords: Evaporative cooling, Condensate, Compressor work.

Abstract

The air conditioning machine commonly used is air conditioning system with a vapor compression cycle. The use of air conditioning machines consumes more electrical energy than other household appliances. In this study, the addition of the water mist method in evaporative cooling system with variations of distance of 20 cm, 40 cm, 60 cm so that the energy consumption of split type AC (Air Conditioning) of machines is more efficient. The results showed that the pressure of the condenser using water mist was lower 48 Psig than the pressure of condenser with a cooling load of 2000 W, and lower by 34 Psig of the pressure of condenser without the cooling load. Meanwhile the temperature of the air entering the condenser (Tout) after using a water mist has lower temperature than without the water mist, therefore it can save electricity consumption in the compressor. The temperature of the lowest inlet air of the condenser reached at the use of water mist with a distance variation of 60 cm was 28 ℃. And the relative humidity (RH)  relatively decrease at the exit  of the condenser using water mist with distance variation of 60 cm length was 59.6%. The compressor power decreased lower using a 60 cm distance water mist of 0.52 kW compared to without using a water mist with a 2000 W load of 0.56 kW. So that COP using water mist higher about 5.24 than without a water mist of 4.72. The highest COP was obtained using water mist at a distance of 60 cm

Abstract

Solar radiation heat energy is energy that propagates throughout the earth's surface and is absorbed stored in various objects on the earth's surface. A thermoelectric generator is an electrical generator device that converts heat (temperature difference) directly into electrical energy, using a phenomenon called the Seebeck effect. In this research, this research was carried out by utilizing the absorption of solar radiation heat on a concrete road with a type of cast concrete class III with K 250 and asphalt type AC-WC as a thermoelectric generator. This research uses 3 thermoelectric generator modules type 1848 which will be arranged in series, the cooling system is filled with water using 2 asphalt and concrete variables, each of which has three variations of L, I and Z-shaped heat conductor plates. The test results show that asphalt has energy larger than concrete. L plate is the best plate on both asphalt and concrete roads. This research allows it to be developed to become a reference source of the latest alternative energy. Keywords: Heat Energy, Thermoelectric generator, Plate variation

Abstract

The Portable Beverage Cooler (PBC) has been designed to satisfy the need of cooler apparatus that could be carried easily. The utilization of this apparatus was intended to minimize the environmental damage affected by vapour compression refrigeration system using CFCs Refrigerant. The peltier effect from thermoelectric module was utilized in this PBC and called as Thermoelectric Cooler (TEC). Furthermore, heat-sink and fan were needed to ensure the cooling effect continously worked. To achieved the objectives of this machine (portable, environment-friendly, low watt, affordable), the design consideration are heat load, insulating material, weight of components, electric consumption, and dimension of the cooling box.  The results of the design shows the PBC cooling box dimension is 6 cm x 6.5 x 15 cm. The insulation of the PBC cooling box are polyurethane foam and polystyrene expanded with thickness 6 mm and 5.3 mm, respectively. The alumunium plate was applied as inner wall to enhance the cooling capacity of cooling room temperature. In this PBC was used one stage of TEC that could yield cooling room temperature until 15 oC in 30 minutes operation by consuming 20 W of electricity.
