Computer controlled evaporator operation during fruit cool-down.

 

Evaporator coil refrigerant temperature, room RH, cool-down and mass loss rates were compared in commercial 1200-bin apple storage rooms. Rooms in which evaporator coil ammonia temperatures were dictated by cooling demand required significantly longer to achieve desired RH levels than rooms in which evaporator coil temperatures were controlled by a computer. The overall mass loss rate of apples stored in a room in which cooling load dictated refrigerant temperatures was higher than in a room in which refrigerant temperature was maintained at approximately 1 deg C during fruit cool-down.
