Propane… Possible Commercial Refrigerant?

Source Article: https://www.contractingbusiness.com/refrigeration/propane-makes-comeback In a time when refrigerants are being closely evaluated for their environmental impacts, propane (R-290) is emerging as an increasingly viable alternative. With a global warming potential (GWP) of 3 and an ozone depletion potential (ODP) of 0, R-290 poses virtually no threat to the environment. In fact, the Environmental Protection Agency (EPA) …

THE EFFECT OF CONDENSER SCALE ON SYSTEM PERFORMANCE

How many of you have “scale” on your evaporative condenser? [I am guessing your hand might be in the air]. How many of you feel that this is “normal” and something that should be treated as a “side effect” from running an evaporative condenser? [I am guessing your hand is still up]. Although scale buildup …

CLEAN & EFFICIENT CONDENSERS

This article will target refrigeration systems that utilize air cooled condensers, but the efficiencies to be gained apply to the users of evaporative condensers as well. First, let us remember a couple of important principles of refrigeration; 1) heat (energy) always flows from higher to lower temperatures, and 2) the function of the condenser is …
