Summary

RESEARCH WAS DONE USING A POTATO STORE WITH A 3,000-TONNE CAPACITY AND ACTIVE VENTILATION. THE AUTHORS FIRST GIVE A COMPLEX EQUATION FOR CALCULATING TOTAL HEAT GAINS. THE EQUATION BRINGS IN 22 FACTORS, INCLUDING: FAN CAPACITY, RUNNING TIME OF THE FAN, AREA OF THE AIR DUCTS, AVERAGE AIR SPEED IN THE AIR DUCTS, AVERAGE TEMPERATURE OF THE WALLS OF THE AIR DUCTS, AVER-AGE TEMPERATURE OF THE VENTILATED AIR, DIAMETER OF THE AIR DUCTS, HEAT CONDUCTION THROUGH THE EXTERIOR WALLS, AREA OF THE WALLS, AVERAGE DAYTIME AIR TEMPERATURE, SPECIFIC HEAT CAPACITY OF THE PRODUCT, PRODUCT TEMPERATURE AT THE START AND FINISH, RESPIRATORY HEAT OF THE PRODUCT, AND SHELF LIFE. THE AUTHORS USE AS EXAMPLES 9 SITES IN 3 DIFFERENT CLIMATIC REGIONS OF THE SOVIET UNION. THEY THEN GIVE SOME WAYS TO REDUCE HEAT GAINS: PUTTING MAIN AIR DUCTS OUTSIDE (IN WARMER REGIONS), IMPROVING OUTSIDE-AIR REFRIGERATION (IN COLDER REGIONS), SUITABLE USE OF FLAP VALVES AND DAMPERS. M. C.
