A chemical that produces a refrigerating effect while expanding and vaporizing. Most residential air conditioning systems contain R-22 refrigerant. R-22 is regulated under the Montreal Protocol and in the United States by the Environmental Protection Agency.

R-410A is a blend of hydroflourocarbons, substances that do not contribute to depletion of the ozone layer.

a substance capable of carrying heat which is picked up at a low temperature level and is compressed to a high temperature, whereupon the heat can be removed by the condensing medium, which is either cold water or cold air

the fluid in a refrigeration cycle that absorbs heat at low temperatures and rejects heat at higher temperatures

a cooling preparation taken orally or applied externally.

A chemical that condenses from a vapor to liquid in a practical temperature range for home heating and cooling. In the process of evaporating, the refrigerant absorbs heat, and when it turns to liquid, it releases heat.

A chemical compound used as the medium of heat transfer in a refrigeration system. It picks up heat by evaporating and gives up heat by condensing.

Ingredient that cools inflammation or eases muscle pain.

A naturally occurring or man made liquid which absorbs and releases heat energy in a refrigeration device by changing phase from a liquid to a gas and visa versa in response to the influence of a refrigeration compressor.

Allays thirst; cools

a substance circulated under pressure within a cooling system that produces the refrigerating effect.

This is a liquid with an extremely low boiling point of minus 21.7°F. This gives it unique cooling qualities. Because it responds well to low pressure conditions and condenses easily it is easy to change the temperature of the substance which means it is easy to cool. When it is cooled it absorbs heat quickly and effectively.

A substance capable of carrying heat, which it picks up at a low temperature level, and is then compressed to a higher pressure and temperature, where the heat can be removed by the condensing medium, air or water.

Substance used in refrigerating mechanism to absorb heat in evaporator coil by change of state from a liquid to a gas, and to release its heat in a condenser as the substance returns from the gaseous state back to a liquid state.

A substance which is cooling and can reduce fever.

A substance that remains a gas at low temperatures and pressure and can be used to transfer heat. Freon is an example.

Chemical used to transfer heat by taking advantage of the laws of physics.

A chemical that produces a refrigerating effect while expanding and vaporizing. Most residential air conditioning systems contain R-22 refrigerant. R-22 is regulated under the Montreal Protocol and in the United States by the Environmental Protection Agency. R-22 is scheduled to be in production until the year 2020. It's used in approximately 95 percent of air conditioning equipment manufactured in the U.S. today.

A substance used in a refrigeration system to absorb heat in the evaporator coil, by means of a change of state from liquid to a gas, and to release its heat in the condenser as the substance returns from the gaseous state back into a liquid. Also see Freon.(Added: 12-Sep-1999 Rating: 0 Votes: 0)

A chemical that produces a cooling effect while expanding or vaporizing. Most residential air conditioning units contain the standard R-22 refrigerant, or Freon.

The fluid in a refrigeration system that changes from a liquid to a vapor and back to a liquid at certain pressures.

A chemical that cools air as it evaporates. Air conditioning systems use Refrigerant in the Evaporator Coil to cool air as it passes by.
