R407C Applications
R407C is a zeotropic blend composed of difluoromethane (R32), pentafluoroethane (R125), and 1,1,1,2-tetrafluoroethane (R134a). Each component serves a specific function:
R32 provides heat capacity.
R125 reduces flammability.
R134a lowers operating pressure.
R407C is recognized as a long-term replacement for R22, sharing similar performance characteristics. It is widely used in air conditioning systems and non-centrifugal refrigeration systems for medium and high temperature applications, making it an ideal solution in a variety of HVAC setups.
A cylinder refers to a cylindrical metal component that guides the piston in a straight reciprocating motion within the cylinder. Air in the engine cylinder converts thermal energy into mechanical energy through expansion; The gas is compressed by the piston in the compressor cylinder to increase pressure.
Overview:
R-123 was specifically developed as a replacement for R-11 in low-pressure centrifugal chillers. It is widely used in modern systems engineered with the correct materials and sizes to meet specific cooling needs. However, retrofitting existing R-11 chillers to R-123 may require replacing certain components like seals, gaskets, and other system parts to ensure proper operation and avoid leaks.
Key Features:
ASHRAE Safety Rating: R-123 has an ASHRAE rating of B1, meaning it has low toxicity but requires more stringent safety measures. Lower personal exposure levels are allowed during normal daily operation, but machinery rooms must follow specific requirements as per ASHRAE Standard 15 (Safety Code for Mechanical Refrigeration).
Retrofitting Considerations: When converting from R-11 to R-123, modifications may be necessary, including the replacement of gaskets and seals to achieve optimal operational conditions and leak prevention.
Low-Pressure Performance: R-123 is optimized for low-pressure centrifugal chiller systems, providing efficient cooling and performance in large industrial and commercial applications.
Safety Requirements:
Personal Exposure: Extra precautions must be taken due to the B1 rating, which permits lower exposure levels during service and daily operation.
EPA Certification: An EPA certification card is required to purchase R-123 or any other CFC and HCFC refrigerants, in compliance with environmental safety regulations.
Applications:
Low-Pressure Centrifugal Chillers: R-123 is primarily used in large industrial and commercial systems, providing efficient cooling in these specialized environments.
Retrofitting R-11 Chillers: It serves as an effective replacement for R-11, though retrofitting may require careful modification of existing systems.
