When it comes to cooling your house, the evaporative coolers are most efficient cooling system than any other types. These evaporative coolers provide cold air using less energy and hence it is a much-preferred choice when it comes to keeping house cool. But when the evaporative cooler does not work well, it does not cool any place where it is installed. Most of the air conditioning and evaporative cooling services companies understand all the regular norms and rules to make use of it efficiently. Hence there are a few tips that you should keep in mind that help you to get efficient use of the evaporative coolers.
Humidity:
The first and foremost problem in any kind of air conditioning and evaporative cooling service is the humidity. As soon as water evaporates, the heat in the air is used as a fuel to transform water to vapor. This is when the heat gets absorbed and thereby lowers the temperature of the surrounding area. If the water evaporates faster, more heat will be used and the temperature will drop down as well. This is what happens in an evaporative cooler. The water is pumped up and placed on a cooling pad. This pad has warm air that is blown using a fan. The heat is then absorbed by water. Later the cool air is evaporated from the other side of the system. In principle, the rate of evaporation is inversely proportional to humidity.
Use ice:
Another technique adopted by air conditioning and evaporative cooling services is adding ice on to the water tank. This is meant to increase the cooling capacity. Most services use this technique these days to obtain best results. When the cooler is given for service, most people check first this aspect. And a few companies have started placing separate compartments for putting ice.
When you add ice to the evaporative cooler, the cold air that's blown out will be blown out. But if you are standing right in front, it will not improve the rate of evaporation either. It is not just ice that does the whole exercise, but it is a mix of temperature and humidity in the air that creates the cooling effect.
Also, if there are any problems with getting cold air out of the cooler, the best way is to replace the ice with room temperature water.
The window effect:
The windows can be a boon or a bane when it comes to air conditioning and evaporative cooling services. The foremost reason here is that the heat load from the window will increase the size of the cooler. Also, the sunlight coming through the window makes people inside the house feel hot. You can minimise the problems in various ways.
You should always try to use external shades. This means that verandahs, bamboo blinds, roller shutters can be made to get rid of such problem. Most of the air conditioning and evaporative cooling services suggest this alternate.
Another change that can be added is to use a reflective glass or a film. Though similar to external shade, it is not really used in all houses as it creates an unnecessary reflection.
When you give the cooler for repair, the first thing the air conditioning and evaporative cooling services ask is about the orientation of the windows. The best way to place the cooler is on the north and then maybe on the south.
Another option suggested by air conditioning and evaporative cooling services is to use curtains. This works like thermal glass. The cold winter air at the floor level is reduced using these thermal glasses. During these circumstances always use light colors or a solar backing on the curtain.
