Energy conservation through evaporator fan cycling in a refrigerated controlled atmosphere apple storage facility

Creator:: Koca, Robert W.
Abstract:: 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...

Simulation of energy use by Controlled Atmosphere generation equipment in fruit cold storage

Creator:: Boonprasom, Pichaya
Abstract:: A computer simulation program, Controlled Atmosphere Simulation (CAS), was written in Microsoft Visual Basic 3.0, Professional Edition to evaluate energy use by three type of atmosphere generators used in fruit storage warehouses. The program consists of pulldown time and energy use models for a membrane air separator, an ammonia fractionating...

Extending market potential of blueberries with controlled atmosphere storage

Creator:: Boonprasom, Pichaya
Abstract:: The goal of this research was to determine if controlled atmosphere (CA) storage could be used to extend the market period of fresh Pacific Northwest blueberries and to evaluate the effects different storage atmospheres have on fruit quality. Furthermore, this research also investigated heat and mass transfer characteristics during cooling...

Microprocessor control and numerical model for broiler house summer ventilation utilizing a rockbed heat sink

Creator:: Chen, Chaur-Fong
Abstract:: Summer brooding often requires some form of air modification in addition to maximizing ventilation rate to prevent animal heat stress and possible death due to hyperthermia. A rockbed thermal storage module was designed and constructed to provide sensibly cooled air for a broiler space under summer brooding conditions. A mathematical...

Cooling and mass transfer rates in fresh fruits

Creator:: Chadwick, Jonathan Michael
Abstract:: Moisture loss from fresh fruits results in lost revenue to producers, storage/packing companies, distributors, and increased prices for the consumer. Improved methods of storage and handling are necessary to help prevent moisture loss and retard spoilage. A literature review was conducted to improve knowledge on past and current studies involving...

Computer simulation of transient refrigeration load in a cold storage for apples and pears

Creator:: Adre, Norberto
Abstract:: 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...

A slatted floor portable shelter for lambing in winter rainfall pastures

Creator:: Nicholson, Martin Theodore
Abstract:: A survey of Oregon sheep producers conducted as part of this research, indicated that lambing losses by sheepgrowers in winter rainfall areas of Oregon currently average 16 percent. The majority of the lambs born in these areas are born in pastures without the benefit of shelter. The utilization of portable...

Direct conversion of solar radiation to mechanical power using thermostatic bimetals and linear Fresnel lenses

Creator:: Pritchard, Vernon Ross
Abstract:: Conversion of solar energy to mechanical power through the use of thermostatic bimetals and linear Fresnel lenses was found to be both theoretically and experimentally feasible. Using linear Fresnel lenses to concentrate sunlight on bimetallic coils caused a simple sun powered motor to produce rotational shaft power. However, continuous rotational...

Development of a water-to-water heat pump for tempering water in milking parlors

Creator:: Griswold, Bruce Walter
Abstract:: A water-to-water heat pump was specifically designed and operated to temper process water for cleansing and sanitizing milking parlor equipment using recovered energy from the milk refrigeration system as its heat source. Operation of the water-to-water heat pump in series with the energy recovery system was found to be both...
