The study was performed on a typical residential house located in the hot and mostly dry climate of Kuwait. The house hourly cooling load was calculated using the transient simulation software TRNSYS. A mathematical model integrating the hydronic RC panel and the DPIEC models was developed and ...
In many parts of the world, large differences between the dry-bulb and wet-bulb temperatures during the summer season can be used advantageously to pre-cool fresh air for air-conditioned space using an indirect evaporative cooler (IEC). This paper presents an analytical evaluation using the field...
Meet air cooler expert in Dubai, UAE offering desert, outdoor, evaporative, industrial, and portable cooling solutions online for sale and rent.
Conventional air conditioning systems heavily rely on energy-intensive mechanical cooling, which significantly contributes to both electricity demand and greenhouse gas emissions. Passive cooling strategies, particularly radiative cooling (RC) and evaporative cooling (EC), present an alternative approach by ...
This paper presents an analytical evaluation using the field performance results of a 1180 L/s (2500 ft 3/min) IEC unit and the recorded weather data in coastal and interior locations in Kuwait. Estimated cooling capacity of the IEC is 3.1 and 2.4 tons of refrigeration (RT, 1 RT=3.517 ...
Figure 2. Division of research areas of evaporative cooling included in this study. 3. General Presentation of Technology The indirect evaporative cooling system provides only sensible cooling to the processed air without any moisture addition. In an indirect evaporative cooler, the product air passes...
cooler equipped with a super-performance hydrophilic material layer, complex structure of the heat exchanger and intermittent water supply system. The device performance was compared to a typical commercial dew point air cooler (M30) under five different climatic conditions in the laboratory. The ...
They demonstrated that the pre-cooling effects were significant for the desert climates in China. Waly et al., [3] evaluated the condenser evaporative pre-cooling option on a 2.8-ton/9.8 kW R-22 split unit in Kuwait, and they identified power savings ranging from 8.1 to 20.5%, as a ...
