A two year experiment demonstrated electrical energy savings
through evaporator fan cycling in part of a full-sized refrigerated
controlled atmosphere apple storage facility in Yakima, Washington.
Room cooling demand and evaporator fan operation was controlled by
the bulk fruit temperature. Refrigerant temperature was regulated
by a computer controlled ramping sequence...

Increased consumer demand for fresh fruit throughout
the year has created a need for long term storage. Long
term storage of fruit uses more energy than fresh market
products, thus increasing production cost. Pacific
Northwest energy costs and more competition for markets
has made energy conservation an important factor to...
The formation of frost on a forced convection refrigeration
coil, operating below the freezing temperature is known to have the
effect of imparing the efficiency of a refrigeration system, This
investigation was directed toward the study of the behavior of the
overall coefficient of heat transfer and the air static...
A computer model was created using compressor and
condenser performance data to simulate vapor-compression
ammonia refrigeration system performance under various
operating conditions and strategies. The model was used to
estimate energy, demand, and cost savings resulting from
reduced condensing pressures.
Two ammonia refrigeration systems were selected for the
investigation into...
