Evaluation of Evaporative Cooling for Heat Transfer in the Condenser of Window-Air Conditioners

نویسنده

  • Ebrahim Hajidavalloo
چکیده مقاله:

There is a demand for reduced power consumption in the vapor compression refrigeration cycle. Coefficient of performance of window-air conditioners considerably decreases and power consumption increases under very hot conditions. These problems have encouragecl studies aimed at improving the performance of window-air-conditioners by enhancing the heat transfer rate in the condenser. In this article, a new design for application of evaporative cooling in the condenser of&#10 &#10window-air conditioners is introduced and experimentally investigated. In this design, two pads equipped with a water injection system are located on both sides of the air-conditioner to cool down the air flow passing over the condenser. The experimental results showed that thermodynamic characteristics of the system considerably improved while power consumption decreased by about 15% and the coefficient of performance increased by about 55%.&#10

Effect of Using Evaporative Condenser Instead of Air Condenser in Window-air Conditioners

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...

Assessment of Environmentally Friendly Refrigerants for Window Air Conditioners

This paper presents technical assessment of environmentally friendly refrigerants as alternatives to R410A for window air conditioners. The alternative refrigerants that are studied for its replacement include R32, R600a, R290, R1234yf, R1234ze and a mixture of R32 (90% molar concentration) and R125 (10% molar concentration). Baseline experiments were performed on a window unit charged with R41...

Extending the potential of evaporative cooling for heat-stress relief.

Factors were analyzed that limit the range of environmental conditions in which stress from heat may be relieved by evaporative cooling in shaded animals. Evaporative cooling reduces air temperature (Ta), but increases humidity. Equations were developed to predict Ta reduction as a function of ambient temperature and humidity and of humidity in cooled air. Predictions indicated that a reduction...
