Refrigeration

Refrigeration is the process of drawing heat from substances to lower their temperature generally, for the purpose of preservation.

Wherever fresh or frozen food is stored, processed, sold or transported refrigeration is a necessity.

Refrigeration equipment has been developed for static cold storage, and for mobile applications on ships, trains and aircraft.

Over time insulating materials have become thinner, lighter and more effective.

How Does Refrigeration Work?

In the conventional compression system, which is the system used in domestic and most other applications, there are four main components.

The compressor controlled by a thermostat exerts pressure on a vaporised refrigerant forcing it to pass through a condenser. This refrigerant loses heat and turns to a liquid. The liquid refrigerant then moves through the refrigeration compartment through a series of pipes known as the evaporator. Here the refrigerant vaporises drawing heat from whatever is in the refrigerated compartment. The refrigerant then passes back to the compressor as the cycle is repeated.
