Scorching hot and dry summer months from April to June are unbearable in central India. It is difficult facing the sunlight during the day time and the temperature starts touching 48 Degree Celsius sometimes. Even the room temperature starts exceeding 35 Degree Celsius during these months and one finds no relief from heat even with the ceiling fans. The Evaporative Air Coolers for the relief from heat are the blessing during these days. They can easily bring down the temperature by about 10 Degrees at very minimal energy consumption.
When it comes to cooling of bigger area, air conditioners are of very little utility. Either one has to go for multiple Air conditioner units or has to opt for central air conditioning possibility. But both these option have higher installation cost and higher running cost as they involve high energy consumption during the operation.
Air coolers are very practical option for cooling bigger area especially during the dry hot summer days. Number of air coolers for summer are available these days with models ranging from small room coolers to desert cooler and duct coolers One can easily fix bigger desert/duct cooler outdoor to achieve the cooling throughout the house.
Although there is yearly maintenance required in terms of cleaning the tank when summer season is over, which is not the case with Air Conditioner. But this little effort is worthwhile looking at the cost saving involved with usage of cooler against the Air Conditioner. The noise free desert/duct cooler available these days can be fixed outdoor and do not utilize the room space. These coolers therefore can be useful even in the modern houses with the space constraint.
The cooling efficiency of evaporative Air Cooler is dependent on the cooling pad area. So while selecting the suitable model, one must go for the cooler model offering bigger cooling pad area. Steel body cooler generally are able to offer higher cooling pad area compared to the fiber body coolers. Another major point worth consideration is the water tank capacity which should be sufficient enough for the night long operation of the cooler.
