President’s Message by Dave Rule

This issue of the Condenser is all about operations. As you can see from our cover, one of the most important factors in that equation is geographical location. The regional and local operating environments define the business and regulatory landscape across the country. And that definition, in turn, determines how we uphold our high standards for safety and efficiency. The role that the regulatory framework plays in our industry, and even more importantly, how we respond to and inform it, is a central focus for IIAR.

THE LOCATION LANDSCAPE

The cost of real estate, an available workforce and proximity to transportation dictate where businesses build industrial refrigeration facilities, and those factors are more important than ever in recent years. As rising demand spurs cold chain growth, clear winner (and loser) locations are emerging from the patchwork of regional U.S. regulatory and business environments. Increasingly, those environments are taking center stage in decisions to build a facility or what refrigerant to use.

Energy and Function Analysis of Hot Gas Defrost in Ammonia Refrigeration Systems

Traditionally one of two methods for controlling drainage of the evaporator during hot gas defrost is used: pressure control, which keeps the pressure in the evaporator constant during defrost, or liquid drain control, which uses a float valve to drain condensed liquid from the evaporator. Each method’s energy consumption is quite different, as the pressure-control method bypasses a certain amount of hot gas during the defrost period.
