In its simplest terms, refrigeration is simply the removal of heat from one medium to another by use of inert gas. In the case of refrigerated containers, it is removal of heat from inside the box - the cargo and surrounding air - to outside the box. The inert gas most commonly used is named R-12.
producing a cold climate within a closed space or chilling a substance to some point below its starting temperature.
Storing cigars in an airtight bag in a fridge is not recommended for at the very least the cigars will have to be returned to room temperature for at least 30 minutes before you can smoke them. More importantly, the cold will impair the flavour and aroma of a fine cigar. It's best to keep fine cigars away from extremes of cold or heat in a proper humidor.
The protection of perishable freight against heat.
deliberately lowering the body's temperature for therapeutic purposes; "refrigeration by immersing the patient's body in a cold bath"
The process of removing heat from one place where it is not wanted and transferring that heat to a place where it makes little or no difference, ie outside.
Withdrawal of heat from a chamber (refrigeration load) to achieve temperatures lower than ambient temperatures; after heat is withdrawn from refrigeration load it is transferred to a condenser and dissipated to air or water coolant
The removal of heat by mechanical means.
The process of the absorption of heat from one location and its transfer to another for rejection or recuperation.
Refrigeration is the process of removing heat from an enclosed space, or from a substance, and rejecting it elsewhere for the primary purpose of lowering the temperature of the enclosed space or substance and then maintaining that lower temperature. To satisfy the Second Law of Thermodynamics, mechanical work must be performed to accomplish this.
