Do you know how an air conditioning system operates automatically? You may think this issue is not significant, but in places where air conditioning is essential, this automatic operation becomes crucial as it effectively regulates the temperature.
An air conditioning system (thermostat) controls the temperature in a room or the necessary temperature for a specific industry. For instance, temperature control is essential for devices like irons, frying pans, clothes dryers, and water heaters. In a temperature-controlled room, the thermostat will “command” the cooling unit to activate or deactivate when the temperature rises or falls.
How does the temperature control unit work? Similar to a thermometer, the thermostat senses temperature changes. A thermometer indicates temperature variations on a scale marked in “degrees.” The thermostat operates through a mechanism that maintains the set temperature. For example, a heater in colder regions keeps your home at a certain temperature. If the room temperature drops—meaning it gets cold—the temperature sensor notifies the heater to “increase” or restart its operation.
Once the room reaches the predetermined temperature, the sensor automatically instructs the heater to reduce or cease operation. Instead of using mercury as the temperature sensing element—like in traditional thermometers—thermostats commonly use a specially designed piece of metal. This metal piece bends based on specific temperature levels. The bending acts as a connection for electrical circuits—either activating or deactivating the flow of electricity, allowing the device to operate according to the set temperature.
