Thermostat often called temperature control, cooling control, and cool control. Thermostat controls the compressor work automatically based on a Thermostat temperature limit switch automatically based on temperature settings. If the evaporator temperature according to the temperature setting the thermostat will automatically disconnect and reconnect power to the compressor. For some time, the compressor and the rest will work again when temperatures evaporate exceeds a predetermined temperature. Thermoste put on the wall as part of the evaporator is a source of anti-heat (cold), so that the thermostat can respond to a change in temperature of the evaporator
There is a thermostat which is equipped with a liquid-filled tube. This liquid is volatile. The tube is placed in the engine room cooling (evaporator space and distributed by capillary gas into space. If the space in the engine coolant reaches the freezing point (in evaporato achieving extremely low temperatures), then the liquid freezes role in the thermostat tube. Liquid which freezes the roots shrink. this means that the gas from the gas space will flow into the capillary tube is empty. become loose gas space Consequently, the spring will press it so the contact switch is open. Accordingly, the electrical circuit will be disconnected from the voltage source. this means dynamo stops and the compressor stops until If the temperature in the engine room evapotator up cooling (evaporator) temperature rises again (not at freezing point), the gas in the tubes melt will change. this means that the gas space pressure, switch contacts will be in contact. dynamo and compressor working again. this occurs continuously automatically.
In addition to using the press system as above, there is a kind of thermostat which uses leverage system. How it works pretty much the same, but a different outlet. At the thermostat has a leverage system components such as bellows (a kind of rubber that contains gas), pear or spring, spacer bolts, switch or outlet, and a capillary tube. Bellows in the form of gas space (same as above thermostat tap system), while the bellows pears to suppress. If the bellows expands the pear by itself will be pressing. If the temperature of the evaporator is at the freezing point, then there is gas in the bellows will flow into a capillary tube because there is a vacuum in the tube. Thus bellows will contract. As a result, pears pressed down. When pears pressed down, spring will be pressured downwards. Thus the other side of the opening, so that the electrical connection is disconnected. This means that the dynamo and the compressor stops working. If the dynamo and compressor die slowly, then the evaporator temperature at start up (freeze began to thaw). Thus the tube had to press the gas expansion bellows through the capillary. Bellows expands upward and pressing the spring. This means the other side of the spring is moving upwards. This movement caused the electrical circuit contact. Thus, the motor and compressor working again.
