When I was a child I used to have a lot of curiosity while using a Thermos (or vacuum flask). It was always like magic that it used to keep hot things hot and cold things cold all the time. It neither had fire in it to keep things hot nor ice to keep things cool. Later in high school we learnt the basics of heat transfer, and that was when the theory behind the thermos became clear to me. After so many years, when I think of it, a lot of it can be applied to saving
We all like to live in the comfort of air conditioners or heaters, but most of us are also aware that these appliances significantly increase our electricity bills. Although there are multiple ways of reducing electricity bills due to air conditioning or heating but nothing can be better than having a good insulation in a room. A good insulation can even help you avoid using these appliances if the temperature in your room is comfortable
Extreme weather is uncomfortable to everyone and we all like to sit in a cold room during hot summer months and in a warm room during extreme winters. We use appliances like air conditioners and heaters to make rooms comfortable but it increases the electricity bills significantly. In addition to various other ways, there are simple techniques of thermal insulation that can make the environment much more comfortable and can reduce the electricity consumption. In case
We all love to have windows in our house. They infuse beauty and warmth of natural light and brighten every small and little space alike. They improve the ambience of the room and make us feel better. Unfortunately they also let a lot of heat exchange from outside the room. During summers, heat through the window can increase the temperature inside and in winters it can let the heat through the room escape impacting units consumed (of electricity) for air conditioner
Walls of your room which are directly facing the sun can bring in a lot of heat in the room and can significantly impact air conditioning load. Even a hot ceiling with a ceiling fan on can throw a lot of hot air in the room that is being air conditioned. This can increase air conditioning load by up to 20% and can thereby increase your monthly units consumed on your electricity bill. Heat naturally flows from warm areas to cold
Thermal insulation is a very important aspect which has to be thought about when putting an air conditioner or heater in a room. Significant amount of heat is exchanged with the outside environment through walls and windows and the best way to improve air conditioner or heater efficiency is by putting right thermal insulation in the room. Double glazed glass or Insulated glass is the best way to protect heat loss through windows.
