Answer to Question 1

Since most refrigeration systems operate at evaporating temperatures below 32F, frost will accumulate on an evaporator surface. This frost must be removed on a regular basis; otherwise it will begin to insulate the surface of the evaporator and prohibit the transmission of heat from the product to the refrigerant within the evaporator.

Answer to Question 2

Conventional thermostat, a suction pressure cut-out control, or an evaporator pressure regulator.
