How can pressure be used to control the temperature of a refrigerated space?
What will be an ideal response?
A partially filled liquid sensing bulb can be placed inside the refrigerated space. As the box temperature drops, the liquid contracts and the pressure in the bulb will decrease. This in turn will reduce the pressure on a diaphragm, causing the circuit to the compressor to open.
