A ton of refrigeration can be defined as the amount of heat removal to produce one ton of ice at 32° from one ton of water at 32°. But what else does it mean?

An excessive pressure drop across the suction line will reduce the operating capacity of a refrigeration system.

Techs may not see the importance of the service ticket, but they should, since it can be an accurate reflection of him and his work. 

High-pressure switches are designed to shut down a compressor if the system’s high pressure rises above an unsafe level, not allowing the compressor to restart until the pressure returns to a safe level. 

One field problem frequently encountered with this type of metering device is that it can become plugged with system debris, causing a restriction. When this happens, the cap tube will typically need to be replaced.

Joe Marchese explains the refrigerant flow control device, which prevents the refrigerant pressure in an evaporator from operating below a minimum value, and discusses how to select the right one for the job. 

Relief valves are used to release abnormally high pressure inside a vessel before that pressure causes the vessel to erupt. 

How you handle leaving a job site is as equally important as how you handle arriving and conducting the repair or installation. 

A popular electrical component used on many control circuits is the step-down transformer. It is the power source for a separate lower-voltage circuit which typically controls the operation of a system. 

Determining that a compressor has failed on a refrigeration system is normally a relatively simple procedure. But, discovering why the original compressor failed may not be as simple.
