In this paper, the application of evaporative cooling for refrigeration cycle to reduce power consumption in hot climates is emphasized. Experimental and analytical investigations were performed in order to specify the effect of evaporative cooling condenser instead of the commonly used air cooling condenser in window-air-conditioners. Evaporative condenser can reject more heat, thereby preve...
In a steam power plant, the temperature of the cooling water leaving the condenser for recyclingshould decrease. This is achieved in a cooling tower. The Heller cooling tower does not require waterfor operation, thus, it is a suitable system for use in thermal power plants throughout Iran. Wind is anenvironmental factor that unfavorably affects the performance of a cooling tower. Previous studi...
Electrical power generation can be achieved through many means, one of which includes using a gas turbine. Gas turbine performance is highly dependent on ambient temperature; as temperature increases output lessened. This huge problem in warmer regions like Nigeria. turbines use the surrounding air to generate electricity and this gives rise method or curbing effect high temperatures. Once volu...
The present study investigates the effectiveness of thermostat control strategy in cooling energy consumption in residential buildings. To evaluate the energy consumption, two scenarios including a residential zone with and without the thermostat control system are assumed. The TRNSYS software provides an efficient numerical tool to model and evaluate a cooling system. Furthermore, since solar-...
Three commercially available microclimate cooling systems were evaluated for their ability to reduce heat stress in men exercising in a hot environment while wearing high insulative, low permeability clothing. Five male volunteers performed three 180-min experiments (three repeats of 10 min rest, 50 min walking at 440 watts) in an environment of 38 degrees C dry bulb (Tdb), 12 degrees C dew poi...
Stepwise regression method (SRM) was employed in order to develop simple and accurate models for prediction of supply air temperature and pad’s pressure drop of a cellulose evaporative cooling pad system. After validation of the obtained models, influence of variation of effective performance parameters on water and electricity consumption of a cooler which supplied a specific volume of c...
Due to the increasing importance of energy, optimizing power generation systems and reducing their internal energy consumption are essential issues. Analysis of power generation systems is necessary regarding energy and recognition of their functioning. The present study investigated the effect of media system on the performance and emissions of environmental pollutants in Thermoflow Software b...
In this paper, the cooling system of the air humidifire, completely powered by solar energy, has been designed and optimized. In the cooling system, instead of conventional compression cooling systems, the ammonia absorption refrigeration system has been used.Its design is done in a way that the performanceof the system has increased remarkably in environments with high temperature. The ammonia...
Reduction of data centre power consumption is a timely challenge. Waste heat reuse is another focus area when developing energy efficient and sustainable data centres. And these two issues are interconnected through liquid cooling of server racks and/or direct-to-chip liquid cooling. Both of these solutions make it possible to transfer a significant proportion of the waste heat energy back to p...
