Production of Cost effective cooling using Eco-cooler

Abstract

Thermal comfort is defined as “that condition of mind which expresses satisfaction with the environment”. This condition is also sometimes called as “neutral condition”. A living human body may be likened to a heat engine in which the chemical energy contained in the food consumes continuously converted into work and heat. The rate at which the chemical energy is converted into heat and work is called as “metabolic rate”. A human body is very sensitive to temperature. The body temperature must be maintained with a narrow range to avoid discomfort, and within a somewhat wider range, to avoid danger from heat stress.

Present project deals with providing cost effective cooling using eco-cooler. Eco-cooler works on the principle of Latent Heat Storage (LHS) technique which is provided by using PCM (Phase Change Material).The reason for adoption of eco-cooler to provide cost effective cooling is drawbacks of passive cooling system like high initial building cost, requires more planning to reduce glare, require
engineering expertise. In eco-cooler reduction of air temperature is achieved using PCM based evaporative cooling system.

Eco-cooler is best suited to hot and dry climatic regions like Anantapuramu. Basically anantapuramu is backward region, where rural population is high compared to urban population. Majority of this population cannot afford conventional Air conditioning system. So an effort is made to test and implement the proposed eco-cooler which has yielded a cost effective solution to the cooling problem. In the present project comparison of temperatures with dry and wet basis is performed. The room temperature is found to be reduced by 1 to 2℃ less than ambient temperature.
