The XPERT refrigerator thermostat weighs 0.2kg and is designed specifically for refrigerators.
What Is a Thermostat?
A thermostat, or temperature relay, is an automatic temperature controller. Its primary role is to maintain a consistent internal temperature within a device. For instance, refrigerators allow users to set a specific temperature. Once set, the cooling system ensures the temperature remains steady. When warm air enters the refrigerator and the internal temperature rises above the set limit, the thermostat signals the compressor to start working. As the temperature drops back to the desired level, the thermostat shuts the compressor off.
How Does a Thermostat Work?
Thermostats act as temperature-sensitive switches. They include a temperature sensor that opens or closes a circuit based on temperature changes. This process completes or cuts off an electrical current, which controls heating or cooling equipment. Thermostats operate either mechanically or electronically. Mechanical thermostats, like the XPERT AWTB-135, are relatively straightforward. They often include a bimetallic strip or a two-piece carbon structure. As the temperature changes, the metal or carbon moves, directing mercury inside the thermostat to shift. This movement activates or deactivates the cooling or heating circuit.
Components of a Thermostat
As a critical part of temperature control systems, thermostats consist of the following components:
- Connection Contacts
- Gas-Filled Bellows
- Metal Body
- Levers and Springs
- Bulb Tube
- Capillary Tube
- Adjustment Screw
The XPERT AWTB-135 Double Door Refrigerator Thermostat incorporates all these components to deliver reliable and efficient temperature control for metal water coolers.
