．． 31 reaches the limit of its adsorption capacity for carbon dioxide CQ2, and the carbon dioxide C02 in the combustion gas can no longer be adsorbed and is exhausted into the storage 1 through the exhaust pipe 4o, and the carbon dioxide CO2 concentration in the storage 1 decreases. It starts to increase gradually. 7577/
This is the state about 2 hours after the start of operation in a storage warehouse 1 with a size of . During this time, the oxygen 02 concentration in storage 1 was initially 21
% continues to decrease. The gas concentration in storage 1 is changed to oxygen (
Q2) = 5%, carbon dioxide (CO2) = 5%, nitrogen (N2)
) = 90% as a predetermined value, the gas monitor 45 indicates that the carbon dioxide gas in the storage 1 has increased and reached 5%.
When it is detected by sampling the gas in the chamber 46, the sequencer 5o input to N4 from the internal contact 55 operates the blower 32 for desorption of the carbon dioxide adsorption device 9, and the regeneration of the adsorbent in the adsorber starts. be done.

At the same time when it is detected that the concentration of 5% has been reached, the air passage switching valve 41.42 switches between the 10° inlet pipe and the connecting pipe 43.
Switching is performed so that the connecting pipe 11 is communicated. Thereafter, by operating the blower 14 at regular intervals and detecting the gas in the chamber 46 with the gas monitor 45, the amount of carbon dioxide C○2 generated by the respiration of the perishables stored in the storage 1 is controlled at a predetermined level. When the concentration exceeds 6%, the carbon dioxide gas adsorption device 9 operates and adsorbs carbon dioxide gas CO2 until a predetermined concentration is reached. To explain this operation, when the gas monitor 45 detects that a predetermined concentration has been exceeded, the blower 14 is operated by the sequencer 5o to which N4 is input from the internal contact 56, and the gas in the storage 1 is transferred to the inlet pipe 10. Switching valve 41. Connecting pipe 43. Switching valve 42. Blower14. Connecting pipe 11.
Excess carbon dioxide Co2 is introduced into the adsorber 22 through the switching valve 28 and the inlet pipe 24, and is adsorbed by the adsorbent 30, and then passed through the discharge pipe 26. Switching valve 29. It passes through the exhaust pipe 4o and circulates to the storage 1. On the other hand, the adsorber 23 is supplied with outside air by the blower 32 through the switching valve 33. Introductory tube 36.
The carbon dioxide gas Co2 is desorbed and regenerated by passing through the exhaust pipe 27 and being blown onto the adsorbent 31. Since this is done alternately at regular intervals, the carbon dioxide C in the storage 1
The O2 concentration returns to the predetermined concentration. Further, when the gas monitor 45 detects that the oxygen 02 concentration in the storage 1 becomes 61% or more during storage, the internal contact 61 operates and a signal is input to N2 of the sequencer 50.

態で貯蔵する事ができる。As described above, according to this embodiment, there is a combustion furnace 12 that burns fuel containing carbon, a blower 14 that circulates air for combustion, and an adsorber that contains an adsorbent to adsorb excess carbon dioxide gas. 22, 23, and air path switching valves 28°29.33, 38, 41.42. installed on these pipes.
49, a sequencer 50 that detects the gas atmosphere in the storage chamber 1 and operates each part, a concentration setting function that can be set arbitrarily, a contact 48 that operates at the set concentration, and a concentration higher than the set value set in the concentration setting function by an arbitrary concentration. Since it is equipped with a gas monitor 45 having contacts 51 and 52 that operate at high and low concentration values, perishables can be stored in clean gas, and furthermore, during storage, oxygen and carbon dioxide in the storage 1 are kept at 0°. Even if the gas Co2 concentration deviates from the set concentration, the concentration can be easily returned to the set concentration. Also, the gas monitor 46 displays oxygen o2. Since the control range of oxygen concentration is automatically determined by simply setting the carbon dioxide gas Co21 degrees, there is no malfunction of oxygen concentration control due to input errors, so perishables can be stored in a stable state.

を安定した状態で保存することができる。Effects of the Invention As described above, the present invention provides a storage for storing perishables by burning fuel containing carbon, a combustion furnace for burning fuel containing carbon to introduce carbon dioxide into the storage,
A blower that circulates air from the storage to be used for combustion of the fuel in the combustion furnace, an absorber containing an adsorbent to adsorb excess carbon dioxide gas generated from the combustion furnace, and piping that connects these. a plurality of style switching valves provided in the storage chamber, a means for detecting the gas atmosphere in the storage chamber and operating each part, a concentration setting function that can be set arbitrarily, a contact point that operates at the set concentration, and a setting set for the concentration setting function. Since the gas monitor is equipped with a contact that operates at a concentration value higher than the value by an arbitrary concentration, and a contact that operates at a concentration value lower by an arbitrary concentration than the set value set in the concentration setting function, Since carbon-containing fuel is combusted and oxygen 02 in the storage gas is converted to carbon dioxide CO2, no gas harmful to fresh food is generated and fresh food can be stored in clean gas. Furthermore, by simply setting the oxygen 02 concentration on the gas monitor, the oxygen 02 concentration control width is automatically determined, reducing input errors and making it easy to return to the set concentration even if the storage gas falls outside the set concentration. This allows perishables to be stored in a stable state.
