For larger molecules, numerical "digits" exceeding 9 may occur; in this case, these numbers are separated by dashes. For a cyclic carbon skeleton, the prefixed capital letter "C" is used. For an oxygen-containing refrigerant (an ether), the prefixed capital letter "E" is used. [1]: §4
Refrigerated dryers employ two heat exchangers, one for air-to-air and one for air-to-refrigeration. However, there is also a single TRISAB heat exchanger that combines both functions. The compressors used in this type of dryer are usually of the hermetic type and the most common gas used is R-134a and R-410a for smaller air dryers up to 100 ...
R-410A was invented and patented by Allied Signal (now Honeywell) in 1991. [5] Other producers around the world have been licensed to manufacture and sell R-410A. [6] R-410A was successfully commercialized in the air conditioning segment by a combined effort of Carrier Corporation, Emerson Climate Technologies, Inc., Copeland Scroll Compressors (a division of Emerson Electric Company), and ...

R407C is employed in a variety of cooling and refrigeration contexts: Residential Air Conditioning: Ideal for cooling home environments efficiently. Commercial Air Conditioning: Suited for larger commercial spaces, including offices and retail locations. Industrial Refrigeration: Used in industrial processes requiring precise temperature control.
In the late 1920s, a research team was formed by Charles Franklin Kettering in General Motors to find a replacement for the dangerous refrigerants then in use, such as ammonia. [3] The team was headed by Thomas Midgley Jr. [ 4 ] In 1928, they improved the synthesis of CFCs and demonstrated their usefulness for such a purpose and their stability ...

The TXV power element will need to be changed to a 404A/507A element and critical seals (elastomers) may need to be replaced. R-422D is for use in low-temp applications, and is mineral oil compatible. R-424A is for use in air conditioning as well as medium-temp refrigeration temperature ranges of 20 to 50˚F.
