Reclamation, as it refers to refrigerants, is one of three components in a refrigerant management process. The EPA defines refrigerant reclamation as "Reclaim refrigerant means to reprocess refrigerant to at least the purity specified in appendix A to 40 CFR part 82, subpart F (based on AHRI Standard 700–1993, Specifications for Fluorocarbon ...
A refrigerant is a working fluid used in the cooling, heating, or reverse cooling/heating cycles of air conditioning systems and heat pumps, where they undergo a repeated phase transition from a liquid to a gas and back again.
Air Conditioning, Heating and Refrigeration Institute - In particular, standard 700 helps define levels of refrigerant reclamation, and standard 740 defines standards for recovery equipment; ASHRAE - In particular, standard 15 helps define refrigerant safety groups; HVAC Technical Standards Organizations; Occupational licensure; Ozone depletion
Diagramatic operation of a thermal wheel Ljungström air preheater by Swedish engineer Fredrik Ljungström (1875–1964). A thermal wheel, also known as a rotary heat exchanger, or rotary air-to-air enthalpy wheel, energy recovery wheel, or heat recovery wheel, is a type of energy recovery heat exchanger positioned within the supply and exhaust air streams of air-handling units or rooftop ...
A regenerative thermal oxidizer (RTO) is an example of a waste heat recovery unit that utilizes a regenerative process.. A waste heat recovery unit (WHRU) is an energy recovery heat exchanger that transfers heat from process outputs at high temperature to another part of the process for some purpose, usually increased efficiency.

A representative pressure–volume diagram for a refrigeration cycle. Vapour-compression refrigeration or vapor-compression refrigeration system (VCRS), [1] in which the refrigerant undergoes phase changes, is one of the many refrigeration cycles and is the most widely used method for air conditioning of buildings and automobiles.
The civil emergency service estimates that 10,000 bodies remain under the rubble, calling for heavy machinery and earth-moving vehicles to help in the extraction process, which officials expect to ...
