Abstract: PURPOSE:To prevent a toxic gas from being generated and to safely supply fuel by providing a fresh foodstuff storage compartment, a furnace that burns solid fuel containing carbon, a fan to circulate air, an excess carbon dioxide gas adsorber and a sealed container containing fuel and a fuel supply device. CONSTITUTION:A shutter 50 supplies solid fuel 19 deposited in a sealed container 48 to a furnace at right timing. The air in the storage compartment 1 is supplied to the furnace 12 through a duct 10 by a fan 14 to burn the solid fuel 19. The waste gas enters into an adsorber 22 through cooling unit 13. switch valve 28 and duct 24. Carbon dioxide is adsorbed by adsorbing material 30 therein, and only nitrogen is circulated to the storage compartment 1 through discharge pipe 26 and switch valve 29. After a certain elapsed time, the switch vales 28, 29 are switched to cause the carbon dioxide entering the adsorber 23 is adsorbed by the adsorbing material and only nitrogen N2 is circulated to the storage compartment 1. If the adsorbing materials 30, 31 reach their limits of adsorption capacity during such a process, a fan 32 is operated to supply air to the adsorbing materials to desorb the carbon dioxide and perform regeneration.

Abstract: PURPOSE:To prevent toxic gases from emitting in a storage house, by changing the capacity of gaseous carbon dioxide adsorbers with capacity variable changeover valves. CONSTITUTION:A carbon-containing fuel is burned in a combustion furnace 12 to convert oxygen of a gas in a storage house 1 into gaseous carbon dioxide. Air required for combustion is circulated with a blower 14. The capacities of adsorbers 22 and 23 are changed with capacity variable changeover valves 51 and 52 according to the size of the storage house 1. Unnecessary gaseous carbon dioxide is adsorbed and the oxygen concentration in the storage house due to oxygen desorption of the adsorbers is simultaneously prevented from increasing. A gas monitor 45 for sensing a gas atmosphere in the storage house is connected to a means 50 for operating respective parts.

Abstract: PURPOSE:To increase the accuracy of gas concentration control by providing a blower-controlling means which stops the blower after the gas concentration reaches a prescribed level in the chamber and driving the blower for a certain time every a certain interval and a monitor to detect the gas in the chamber, after start of operation. CONSTITUTION:When the gas atmosphere reaches the setting values in the storehouse and the gas monitor detects the start of storage, the blower controller 44 stops the blower 14. Then, the inner timer and counter are reset, and the timer drives the blower on the passage of 1hr. Further, after 1hr and 1min, the timer allows the gas monitor 45 to work and input the data of gas concentration 3 times, when the blower 14 to stop.

Abstract: PURPOSE:To eliminate harmful gas in a combustion furnace in a perishable material preservation apparatus circulating exhaust gas of a combustion furnace to a perishable material storage chamber to increase the carbon dioxide gas concentration in the storage chamber, by providing a means for releasing the gas in the combustion furnace to be outside of the apparatus. CONSTITUTION:Carbon dioxide gas generated from a combustion furnace 12 is supplied through a blower 14 and adsorption devices 22, 23 to a storage chamber 1 for the preservation of perishable material and the air in the storage chamber 1 is circulated to the combustion furnace 12. The perishable material preservation apparatus having the above structure is provided with a means to release the gas in the combustion furnace 12 from the apparatus when a prescribed time is lapsed after the start of combustion or the temperature near the combustion furnace reaches a prescribed level. When the atmosphere in the storage chamber reaches a prescribed state, the harmful incomplete combustion gas filled in the combustion furnace 12 is released to prevent the intrusion of the harmful gas into the storage chamber 1.

Abstract: PURPOSE:To permit the storage of transporting articles in a cold storage chamber even during cold heat accumulating operation by a method wherein at least one set of a ventilating fan is operated in conjunction with a cold storage chamber temperature detector during the cold heat accumulating operation to control the amount of cold air invading into the cold storage chamber. CONSTITUTION:Cold heat accumulating operation is effected by operating a compressor 40. When cold heat accumulating agent 28 is cooled and solidified perfectly by a cooler 29 and the temperature of a cold heat accumulating temperature detector 44 gives a predetermined temperature, lower than a freezing temperature, a cold heat accumulating temperature detector 43 is operated and the operation of the compressor 40 is stopped. In this case, the inside of a cold storage chamber 36 is not cooled to a cold storage temperature and, therefore, the b-contact of a cold storage chamber temperature detector 39 is in a conducted condition and both of ventilating fans 30, 31 are operated to ventilate air. When the inside of the cold storage chamber 36 is cooled to the cold storage temperature, the b-contact of the cold storage chamber temperature detector 30 is released from the conducted condition thereof and, therefore, only the ventilating fan 31 is operated. The temperature in the cold storage chamber 36 is controlled at a set temperature by repeating above-described operation during cold heat accumulating operation whereby the temperature of transporting articles 48, carried into the cold storage chamber 36, may be controlled at a temperature within the range of set temperatures.
