The idea is that by sealing a quantity of gas in an enclosed vessel the variables V, N, and k are held constant resulting in the pressure of the gas being directly proportional to its temperature.įreezer thermostats use a long hollow tube as the enclosed vessel that is stuffed inside the freezer wall, with a short portion extending into the compressor compartment where one end is connected to a pressure sensor. Some units have them on the side, but I have yet to find one without a coarse adjustment screw.Įlectromechanical thermostats operate on the principle of the ideal gas law, PV=NkT, where P=Pressure, V=Volume, N=Number of gas particles, k=Boltzmanns constant, and T=Temperature in Kelvin. They are usually recessed within the unit and may be covered with tape.
