In this paper, a scheme of hybrid desiccant dehumidification system was proposed. This system can recovery the condensing heat from the vapor compression refrigeration unit to remove moisture from the air. But the trick of energy saving is the sensible heat exchanger after the desiccant rotary wheel. After analysis of its energy consumption characteristic, the system model was established.

The main challenge in the rift valley and low land regions of Ethiopia, the society directly utilize ground hot water for both drinking and shower due to this cause the society is forced to buy cooled bottled mineral water daily. The use of locally fabricated public water coolers seems to be a solution to this problem. The objective of this study is the performance evaluation of locally fabricated public water cooler using a vapor compression refrigeration system. The four basic components of the water cooler, namely, the condenser, evaporator, compressor and the capillary tube are designed and selected separately. The amount of water to be cooled(0.083m^3), ambient air temperature(28℃), water temperature (44℃), the time required to cool water and the evaporator heat load(cooling load of water is 12847.87 KJ) are the predetermined parameters. The raw materials used to fabricate public water cooler are aluminum sheet, compressor, evaporator coil, condenser coil, capillary tube, filter-dryer, refrigerant fluid, water tap, insulator and thermostat. A comparison of experimental and theoretical results has been done and the COP of the cooling system from the theoretical analysis is 3.89 and correspondingly that of an experimental result is 3.17. This shows some variation is observed because of the ideal assumption of the vapor compression refrigeration processes. Also, a Comparison of the present study with literature has been done.

Most of refrigerators commonly use the conventional refrigeration system known as Vapor Compression Refrigeration System becoming a big issue lately due to ozone depleting substance it uses as the refrigerant. This paper will shows step by step of an experiment with the objective of constructing a refrigeration system based on thermoelectric which is reliable and compete able with the Vapor Compression Refrigeration System. The designing of this refrigeration system shows attention to the environment that is combined with the knowledge so the environmental friendly technology can be applied. The performance of thermoelectric refrigerator was conducted under variation of input power (40W, 72W, and 120W) and operated in ambient temperature and cooling load of water 1000mL to investigate the characteristic of system, the performance, and also the COP. The COP is decrease by increasing of cooling load, QL. The best actual COP is 0.182 reached when the refrigerator operated at input power 40W. The result, it shows that decreasing of ambient temperature affects the decreasing of cabin temperature. Thermoelectric and heat pipe refrigerator cooling system can reach cabin temperature with power 120Watt (8.73A, 14V) produces temperature of compartment is 10.63°C indicates effective performance work-based thermoelectric applications.
