Description

Man’s long and persistent building of the “green. house effect” and our recent CFC poisoning of the global “ozone layer” have launched permanent weather changes. Rising world temperatures, falling humidities, increasing ultraviolet radiation, and radically affected food supplies will plague us, beginning last summer.

Considering population growth and weather trends, the demand for cooling will increase in the face of highly priced but diminishing refrigerant supplies and continuously rising power and fuel costs.

Further, conventional air-conditioning efficiencies and capacities will be cut by higher ambient temperatures and by refrigerant substitutions made almost mandatory by the Senate’s ratification last March of the 31-nation CFC control program.

Direct and especially indirect evaporative cooling can help meet the coming emergency in several ways: they use no CFCs, save much power and maintenance, and greatly boost refrigerative cooling outputs and economies by cheaply precooling makeup, return, and condenser cooling air.

New installations in some areas may employ unprecedented amounts of evaporative cooling, but mass replacement of existing conventional cooling seems unlikely, Everywhere else the industry must prepare for boom times unbelievably soon, boosting, not supplanting, refrigerafive cooling.
