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.

Those small-diameter coils — with names like MicroGroove, microchannel, and micro-multichannel — have gained a beachhead in residential heating and air conditioning, and are advancing in commercial HVAC, with refrigeration on the horizon.

International Institute of Ammonia Refrigeration (IIAR) is experiencing a double transition in 2013 as it elects a new chairman and bids fairwell to its retiring Chief Operating Officer.

Designed specifically for refrigeration applications where reliable cooling is required under varying loads and operating conditions, the Generation III outdoor air-cooled condensing units contain one of the manufacturer’s compressors built to handle the rigors of commercial refrigeration. 

When a refrigeration system has lost most of its refrigerant charge in a short period of time, the leak is probably significant and should be easy to find.

Now that the battle regarding ozone depleting potential (ODP) refrigerants has ended with the phaseout of CFCs and HCFCs, the fighting has shifted to issues related to the global warming potential (GWP) of the remaining and newly developing refrigerants.

A-Gas’s acquisitions in the U.S. will set it up for a significant expansion into North America, including the international rollout of its refrigerant reclamation technology
