The Chemours Co. announced it is investing in large-scale manufacturing to expand supply of its Opteon™ family of refrigerants. Chemours will invest $230 million over three years to construct a new facility at its Corpus Christi site in Ingleside, Texas, with start-up expected in the third quarter of 2018.
An undercharge of refrigerant will cause low head and suction pressures, but that is not the only thing that will cause both pressures to be low. An undercharge will have low condenser liquid subcooling readings on the high side, where a dirty air filter for the evaporator will not produce low condenser liquid subcooling readings.
The supermarket industry realized a long time ago that it is impossible to solve environmental problems related to refrigerant leaks using a repair-based approach (i.e., with policies that focus on leak repair and record-keeping). Yet, the U.S. Environmental Protection Agency’s (EPA’s) main regulatory program to address harmful refrigerant emissions reflects a repair-based policy.
