When you feel hot you will also like to cool down a bit. If you feel cold it is obvious that you will like to be warm and cozy. Our body is amazingly built to cope with various temperature changes and keep it at the ideal temperature of 37°C (98.6°F). But what if your home, commercial establishment or industry need heating or cooling or keeping the temperature at the levels that is required for the occasion and operation? You simply cannot keep switching off and on heaters or coolers on your own and waste time and energy. Cooling thermostat steps in here and solves the problem for you as it will do the job admirably and efficiently.
We have clever gadgets known as thermostats that have the capability to accomplish the task with fantastic smartness and importantly save energy and bother for you.
What is a thermostat?
You probably might have a control for regulating the heating or cooling system on your wall and must be marked with degrees. They in fact are not thermometers but known as thermostat which will translate into something like “keep the same heat”. When your home gets very cold, the mechanism will switch on the heating so it could get warm and in real quick time. The mechanism also will switch off the heating when it reaches more than the tolerable temperature. Here we can differentiate thermometer as an apparatus which simply measures and tells you the current temperature. Thermostat on the other hand will try and maintain the temperature roughly on the same level.
How do thermostats work?
So how the cooling thermostats work for you? Most elements when heated up will expand and become big and will get small when it gets cold. Water is an exception because it expands on both counts. This concept is used by thermostats and they switch of an electric circuit connected to the heating system on and off. We have two general types of thermostats and they are gas filled bellows and bimetallic strips.
A typical thermostat has 2 pieces made with different metals joined together by bolt and it is formed as a bimetallic strip. In a heating system this strip acts as a bridge to an electrical circuit. When the bridge is down electricity is carried by the strip and it switches on the heat. When the heat reaches higher levels the strip gets hot and the one of the two metals is expanded. The whole strip bends with the expansion and it breaks the electric circuit to cut off electricity to the heating system. Once the heat is cut off, the room becomes cool. When the strip cools down it attains it original shape and the electric circuit is switched on.
Gas filled bellows
These are better option to the bimetal stripes because they act more quickly. Here a pair of metal discs fitted with gas filled bellows in between is used to regulate temperature. Since the discs used here are bigger they react quickly when temperature rises to higher levels. Heated gas forces the discs apart and triggers the on-off mechanism with greater efficiency.
