Substance used in refrigerating mechanism. It absorbs heat by changing from a liquid to a gas, and releases its heat in a condenser as the substance returns from the gaseous state back to liquid state.
A liquid used to cool devices by absorbing heat from surrounding air or liquid as it evaporates. RING MAIN An industry term for a flow and return circuit transporting fluids or gases. SAFETY SHUT-OFF VALVE A device on a gas appliance which shuts off the gas supply to the appliance to prevent a hazardous situation. A flame failure safety shut-off (or safety pilot) operates when the actuating flame becomes extinguished. A "100%" shut-off valve cuts off all gas, including the main pilot burners. Other types may cut off only the gas supply to the main burner(s).
the fluid used for heat transfer in a refrigerating system. Within a closed system it is evaporated, condensed and evaporated again to transfer heat from the area of evaporation to the area of condensation.
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 but new equipment using R-22 will not be manufactured after 2010. Manufacturers have begun transitioning new air conditioning systems to alternative refrigerants such as R-410A. 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
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 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.
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 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 substance used to provide cooling. Refrigeration Cycle â€“ The cycle that describes the changes that take place to a refrigerant in absorbing heat and subsequently radiating it as it is circulated around a refrigerator
The working agent in an A/C system that absorbs, carries and releases heat. The two primary automotive refrigerants are R12 and R134a, but many other substances have similar properties (primarily a low boiling temperature) that allow them to be used as "a
The compound (working fluid) used in air conditioners, heat pumps, and refrigerators to transfer heat into or out of an interior space. This fluid boils at a very low temperature enabling it to evaporate and absorb heat.
Substance such as ammonia, fluorocarbons (e.g., Freon) and less frequently CO2 and SO2 capable of removing heat from their surroundings by boiling at the desired temperature under economical and safe operating conditions. Also see "Brine."
A refrigerant is a compound used in a heat cycle that undergoes a phase change from a gas to a liquid and back. The two main uses of refrigerants are refrigerators/freezers and air conditioners. Cf. coolant.
