Refrigeration Systems Quiz

Ice Plant Components and Functions

• Ammonia or Freon is used as a refrigerant in the primary circuit of the ice plant.

Expansion Valve

• The expansion valve reduces the pressure of the refrigerant, causing its temperature to decrease, allowing it to absorb heat from the brine solution.

Chilling of Brine Solution

• The brine solution is chilled in the evaporator (also known as the cold box or freezing coil) of the ice plant.

Heat Transfer

• The evaporator transfers the absorbed heat from the brine solution to the primary refrigerant.

Ice Box Insulation

• Heavy insulation in the ice box of the ice plant prevents heat gain, allowing the ice to be stored at a low temperature.

Condenser Function

• The condenser condenses the refrigerant vapor, releasing its heat to the atmosphere, and converting it back into a liquid state.

Expansion Valve Purpose

• The expansion valve's purpose is to reduce the pressure and temperature of the refrigerant, allowing it to absorb heat from the brine solution.

Compressor Function

• The main function of the compressor is to compress the refrigerant vapor, increasing its temperature and pressure, and pumping it to the condenser.

Brine Solution Chilling

• The brine solution is chilled in the evaporator (cold box or freezing coil) of the ice plant.

Ice Box Insulation Purpose

• The purpose of heavy insulation in the ice box is to prevent heat gain, allowing the ice to be stored at a low temperature.
