Summer in India is dry and extremely hot, and the temperature shoots upto 45 to 47 degree Celsius throughout India barring few hilly areas. Proper aeration of house in summer is very important to provide some comfort from the scorching heat. Too many of flat schemes in metros and tier 1 cities built next to each other have left very little space for proper aeration of modern flats. Living the inside these modern flats with little or no aeration in the summers is extremely difficult unless some proper cooling arrangement is ensured.
Majority of the 2-bedroom or 3-bedroom flats have centralized carpet area between 800 to 1100 sft and minimum of three air conditioners are needed to keep the flat completely cool. This becomes expensive affair not only as for higher initial cost air conditioner installation but also for the subsequent higher running cost.
One of the best option, which is becoming very popular these days is installation of Duct coolers in flats. The cooling of entire flat is possible with installation of just one duct cooler, which generally have capacity to cool upto 1100 sft area. Both the installation cost and running cost can be significantly brought down. Additional advantage of Duct cooler installation is that the cool and fresh outside air enters inside house, which keeps you fresh and healthy during summers. These duct coolers are installed from outside the flat so that cool air enters in the big living room which is connected to other rooms thus offering the cooling for entire flat. Other option is to install proper ducting system in the flat so that air flow can be divided and diverted into multiple rooms for centralized cooling.
