The controller 900 compares the concentration of the gas inside the reservoir measured by the gas sensor 830 with a preset value (S1104). When the noxious gas concentration inside the reservoir 100 reaches a preset value, when the noxious gas concentration is applied to the highest priority, the operation of the drying unit 550 is stopped and the exhaust mode V is performed (S1116). When the temperature and the noxious gas concentration are simultaneously applied, the exhaust mode may be performed together with the operation of the drying unit 550.

The controller 900 determines whether or not the internal humidity of the storage measured by the humidity sensor 820 is within a preset value (S1108). If the humidity inside the storage room is within the preset value, the humidity control mode is performed (S1110).

In the above-described drying mode (H), if the humidity measured by the sensor unit 800 is not higher than the preset value, the cooling unit 200 may be maintained inoperable. In addition, the air supply fan 570 and the circulation fans 572 and 574 may continue to operate unless the harmful gas concentration in the reservoir 100 measured by the sensor unit 800 reaches a preset value.

In the humidity control mode, when the internal humidity of the reservoir is higher than the upper limit set value, the controller 900 may operate the cooling unit 200. Therefore, the dehumidification mode by the cooling unit 200 can be performed.

In one embodiment of the present invention, when the dehumidification by the cooling unit 200 is in progress, the reheat heater 260 is operated to prevent the temperature decrease and the dehumidification efficiency decrease by the cooling unit 200.

When the humidity inside the reservoir reaches the lower limit set value according to the dehumidification, the operation of the cooling unit 200 is stopped and the drying mode is performed again (S1112).

In the humidity control mode, in order to cure the high humidity, when the internal humidity of the reservoir is lower than the preset value, the controller 900 may operate the humidifying unit 700. Therefore, as the water supply solenoid valve (not shown) and the air supply solenoid valve (not shown) of the humidifying unit 700 are opened, the humidifying unit 700 sprays water into the reservoir 100 and supplies it. Such moisture may be diffused and evaporated inside the reservoir 100 by the circulation fans. Meanwhile, when the humidity measured by the humidity sensor 820 reaches a preset value, the controller 900 controls the humidity inside the storage 100 by blocking the water supply solenoid valve and the air supply solenoid valve.

In the exhaust mode (V), the exhaust unit 650 is operated to discharge the harmful gas inside the reservoir 100 to the outside. In this case, the cooler exhaust fan unit 360 can be operated together with the exhaust unit 650 for rapid ventilation.

The exhaust mode V after curing and drying may be performed for an exhaust fan operation set time V.1, for example 60 minutes.

When the exhaust mode (V) is completed, the control unit 900 checks whether the automatic switch to the cold storage mode (A) (Aut) (S114), when the automatic switch to the cold storage mode (C) is set (V.3vc ) It is automatically switched to the cold storage mode (C) and performed (S120).

In one embodiment of the present invention, if the exhaust fan operation set time (V.1) has elapsed, the cold storage mode (C) is performed after the compressor operation delay time (C.dt), for example, 60 seconds have elapsed. Can be.

In the cold storage mode (C), the compressor and the condenser fan, that is, the condensing unit (not shown) is operated and the cooler fan 220 of the cooling unit 200 is operated (S1206). In addition, the circulation fans 572, 574 can be operated together with the cooling unit 200.

During the cold storage mode C, defrosting of the cooling unit 200 is removed using the defrost heater 250 to remove the frost formed in the cooling unit 200 (S1208).

Specifically, when the defrost cycle dec, for example, 300 minutes elapses during the execution of the cold storage mode C, the cooler fan 220 and the circulation fans 572 and 574 stop and the defrost heater 250 operates. do. On the other hand, the compressor and the condenser fan is powered off and the operation is stopped.

When power is applied to the defrost heater 250 installed in the cooling unit 200, the defrost heater 250 is operated for a defrost time (det), for example, 20 minutes to increase the internal temperature of the cooling unit 200. do. Therefore, the defrost heater 250 removes the frost formed in the cooling unit 200.

In one embodiment of the present invention, according to the priority selection application order in the cold storage mode (C), the humidity in the storage 100 can be measured by the humidity sensor 820 (S1210).

The controller 900 determines whether or not the internal humidity of the storage measured by the humidity sensor 820 is within a preset value (S1108). If the humidity inside the storage room is outside the preset value range, the humidity control mode is performed (S1110).

In the humidity control mode, when the reservoir internal humidity is higher than the upper limit set value, the controller 900 may operate the cooling unit 200. Therefore, the dehumidification mode by the cooling unit 200 can be performed.

In one embodiment of the present invention, when the dehumidification by the cooling unit 200 is in progress, the reheat heater 260 is operated to prevent the temperature decrease and the dehumidification efficiency decrease by the cooling unit 200.

When the humidity inside the reservoir reaches a set value of the dehumidification according to the dehumidification, the operation of the cooling unit 200 is stopped.

In the humidity control mode, when the internal humidity of the reservoir is lower than the preset value, the controller 900 may operate the humidifying unit 700. Therefore, as the water supply solenoid valve (not shown) and the air supply solenoid valve (not shown) of the humidifying unit 700 are opened, the humidifying unit 700 sprays water into the reservoir 100 and supplies it. Such moisture may be diffused and evaporated inside the reservoir 100 by the circulation fans. On the other hand, when the humidity measured by the humidity sensor 820 reaches a humidification set value, the controller 900 controls the humidity in the storage 100 by blocking the water supply solenoid valve and the air supply solenoid valve.

In one embodiment of the present invention, the temperature inside and outside the reservoir 100 may be measured by the temperature sensor 810 according to the priority application order in the cold storage mode C (S1202).

The controller 900 determines whether the temperature difference between the inside and the outside of the storage measured by the temperature sensor 810 is within a preset value (S1204). In the cold storage mode (C) of the winter season, when the set temperature inside the reservoir is higher than the preset value (for example, 15 ° C. or more) than the temperature of the outside air, the cooling unit 200 is not operated and the air supply unit ( 600) and the exhaust unit 650 is operated (S1216).

The air supply unit 600 supplies air of a relatively low temperature outside the reservoir 100 to the inside, and the exhaust unit 650 discharges air of a relatively high temperature inside the reservoir 100 to store the reservoir 100. The internal temperature can be lowered. Therefore, the air supply unit 600 may perform the cold storage mode C by using the cold air outside the reservoir 100 together with the exhaust unit 650. In this case, the cooler fan 220 can be operated together with the exhaust unit 650.

By operation of the air supply unit 600 and the exhaust unit 650, when the temperature inside the reservoir 100 reaches the set temperature, the cooler fan 220 to prevent the temperature inside the reservoir from lowering below the set value. ) Is activated and the air supply and exhaust units 600 and 650 are stopped.

In one embodiment of the present invention, when the heat capacity of the storage is large, the cooling capacity may be insufficient due to insufficient cooling ability only with cold outside air. The temperature sensor 810 detects a temperature change in the storage 100, and the controller 900 determines whether the temperature change inside is within a preset value range (S1218).

When the temperature change in the reservoir 100 does not reach the preset temperature range for a predetermined time, that is, when the cooling efficiency is lowered, it is switched to the low temperature storage mode C by the cooling unit 200.

During the low temperature storage mode (C), defrost may be carried out to remove frost formed on the evaporator, whereby if the temperature of the cooling unit 200 is above the preset value, defrost heat and steam inside the cooling unit An exhaust mode V for discharging the gas to the outside may be performed.

During the defrosting process, the temperature inside the reservoir 100 as well as the cooling unit 200 may increase rapidly by the defrost heater 250. In this case, the cooler exhaust unit 300 detects hot air inside the cooling unit 200 by the defrost heater 240 with the sensor 230 and through the collector 420 of the collector unit 400. By performing the exhaust mode (V) to be discharged to the outside, the defrost heater 250 to prevent the temperature of the storage 100 rises rapidly, and also the gas such as ethylene, carbon dioxide, methane, hydrogen sulfide generated from the storage Can be automatically exhausted at the same time to maximize the shelf life of agricultural products.

In the exhaust mode V, when electricity is applied to the damper driver 432, the blocking sheet 412 of the damper 410 rotates to block the opening 402 and open the connection duct 430. When electricity is applied to the exhaust driving unit 350 and the cooler exhaust fan 362, the cooler exhaust assembly 310 is opened, and the first air inside the cooling unit 200 is exhausted to the outside through the cooler exhaust unit 300. The pressure difference between the inside and outside of the reservoir caused by the air is introduced into the reservoir through the air supply unit 600 to balance the pressure.

After the exhaust mode V is performed, when the temperature of the exhausted air decreases by 15.degree. C., for example, the cooler exhaust unit operating deviation temperature V.4t2, for example, the exhaust mode V is stopped. Power is supplied only to the defrost heater 250.

Thereafter, when the temperature of the cooling unit 200 is raised by the defrost heater 250 and again reaches the cooler exhaust unit operating temperature V.4t1, for example, 20 ° C, the exhaust mode V is performed again. do.

On the other hand, when the temperature of the defrost heater 250 is set to the defrost heater overheat prevention set temperature (OH 2-a), for example, 30 ℃, the power supplied to the defrost heater 250 is cut off. Then, when the temperature of the defrost heater 250 is reduced by the defrost heater overheating set deviation temperature (OH 2-b), for example, 5 ° C to 25 ° C, power is applied to the defrost heater 250 again to defrost The heater 250 is activated.

When the defrosting time det elapses, the defrosting heater 250 may perform the low temperature storage mode C again after the compressor operation delay time C.dt, for example, 60 seconds has elapsed.

During the execution of the cold storage mode C, when the temperature inside the storage 100 becomes the storage set temperature C.st, for example, 0 ° C. or less in the cold storage mode, the condensing unit is stopped.

On the other hand, if the temperature inside the reservoir 100 rises to the deviation temperature (C.dF) in the low temperature storage mode, for example, 2 ° C, the low temperature storage mode (C) after the compressor operation delay time (C.dt) has elapsed. ) Can be performed again.

In one embodiment of the present invention, during the drying mode (H) or cold storage mode (C), it is possible to measure the concentration or humidity of the gas in the storage (100) (S130). Subsequently, it may be determined whether the concentration or humidity of the gas measured by the sensor unit 800 reaches a preset value (S132). When the concentration or humidity of the measured gas is equal to or greater than the preset value, the exhaust mode V or the humidity control mode of the dehumidification / humidification may be performed in the drying mode H (S134). In such a drying mode (H) and a cold storage mode (C), the detailed operation mode may be determined according to the order of priority application and simultaneous application.

As described above, according to the curing and cold storage system and the curing and cold storage method using the same according to an embodiment of the present invention,

Cold storage allows for the curing and drying of produce and cold storage. When curing and drying reaches a predetermined operating condition by the digital controller and various sensors, heat, moisture, gas, etc. inside the reservoir are automatically exhausted, and low temperature storage is automatically possible after the exhaust.

Therefore, it can be installed at low cost as well as new low-temperature storage, freezer, drying room, etc., so that it can be cured, dried, and automatically exhausted without having to build a separate drying room by enormous facility cost. Low temperature storage can be performed immediately, and low temperature storage prevents rapid temperature rise during defrosting to maintain the storage temperature uniformly, increasing the storage period and freshness of the storage, and producing agricultural products by rapid removal of ethylene gas and carbon dioxide. It can maximize the freshness and the storage period of agricultural products, and can lower the temperature inside the storehouse by using relatively low temperature outside air for a considerable period of winter season. Saving, unmanned in curing and drying Furnace, through the reduction of energy and manpower, money can greatly ease the burden of maintaining.

Moreover, the gas generated during low temperature storage and defrosting or curing and drying can be automatically discharged to the outside of the reservoir to improve the storage and quality maintenance of the stored matter, and the maintenance cost and labor cost can be improved by the automation of maintenance and maintenance.
