RIPri

Refers generally to any natural or artificial process by which heat is dissipated. The process of artificially producing extreme cold temperatures is referred to as cryogenics.

• Cooling

• Cold

• Refrigeration

• Thermodynamics

It is the absence of heat, hence in order to decrease a temperature, one "removes heat", rather than "adding cold."

• Cold

• Heat

• Add heat

• Add cold

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.

• Refrigeration
• Heating
• Ventilation
• Cooling

the process of treating air to control its temperature, humidity, cleanliness, and distribution to meet the comfort requirements of the occupants of the space.

• Air Conditioning
• Lighting Control
• Water Filtration
• Heating System
