Refrigeration compressors and air conditioning compressors also carry power-source specifications defined by voltage / frequency / phase. Refrigeration is the process of
cooling a space or substance below environmental temperature. Refrigeration is a process in which work is done to move heat from one location to another. Refrigeration
in the home lagged behind industrial applications. Refrigeration is one of the great modern conveniences that we almost take for granted in our homes—until a refrigerator
breaks down and we end up with spoiled food. Since you don’t want to wait for your refrigerator to break down completely before scheduling repairs, pay close attention to
some of the warning signs that the unit is not working right.
The work of heat transport is traditionally driven by mechanical work , but can also be driven by heat, magnetism , electricity , laser , or other means. Refrigeration
has many applications, including, but not limited to: household refrigerators , industrial freezers , cryogenics , and air conditioning . Heat pumps may use the heat
output of the refrigeration process, and also may be designed to be reversible, but are otherwise similar to refrigeration units.
