Refrigerants

During the off cycle, or especially during a long shutdown, refrigerant will want to travel, or migrate, to a place where the pressure is the lowest. 

The road to wider use of HC refrigerants remains a rocky one — although it is still being navigated. The latest developments involve more revisions to the regulatory landscape, the tweaking of a refrigerant mix to make it more energy efficient in certain applications, and, as always, warnings about flammability.

HRAI released a statement revealing that fire services could be at an additional risk when responding if the building has a highly flammable hydrocarbon refrigerant in its air conditioning system.

A widespread ban of HFCs has been recommended to the European Parliament by the F-Gas Regulation review’s rapporteur, Bas Eickhout, Dutch Green MEP, who has also called for a series of significant amendments to the European Commission’s proposal, published late last year.

As familiar as condensing units are in refrigeration systems, these components are undergoing major changes. Several of those changes are being demonstrated in a number of practical applications nationwide. 

There are several designs for airflow through the evaporator coil, and for draining the condensate water from the coil, depending on the installation. The different designs are known as the A coil, the slant coil, and the H coil.
