Meanwhile, the low temperature and low humidity operation is performed in the night time zone (S1605). Here, the low humidity can be 50 to 70% of the humidity, for example.

The first compressor and the second compressor are operated so as to be in a low temperature state (e.g., 7 DEG C) (S1606), and the first expansion valve for room temperature, the first expansion valve for low temperature, and the second expansion valve are operated (S1607 , S1608).

Then, the first compressor or the second compressor can be controlled while the set temperature range is checked, or the expansion valve can be controlled.

Fig. 17 shows a control method of controlling the humidity.

It is determined whether the current humidity belongs to the reference humidity range (e.g., 70 to 80%) (S1701).

As a result of the determination, if it is determined that the humidity is excessive and dehumidification is necessary, first, the temperature of the air discharged from the thermo-hygrostat is checked and it is determined whether or not it is lower than the reference temperature (for example, 0C) (S1702).

If the temperature is too low, dehumidification will not occur.

Accordingly, when the air discharge temperature is equal to or lower than the reference temperature, the control valve in the branch pipe is operated so that the refrigerant flows into the reheat condenser (S1703).

If the temperature is above the reference temperature, the operation of the reheat condenser is not required.

Then, the first compressor is operated and the room temperature first expansion valve is operated to perform the defrosting operation in the first evaporator (S1704, S1705). Optionally, however, the second expansion valve may be operated in addition to the low-temperature expansion valve, and further the second compressor and the second expansion valve may be operated so as to be dehumidified in the second evaporator.

On the other hand, if it is determined that humidification is necessary due to the lack of humidity, the humidifier is replenished with water (S1706), and the RPM of the blower fan is dropped to reduce the flow rate of air passing through the filter of the humidifier, (S1707).

On the other hand, when the humidifying operation is selectively performed, the operation of the compressor can be temporarily stopped. This is to prevent dehumidification by the evaporator from occurring when the temperature condition falls within the reference range.

It is determined whether or not the carbon dioxide in the container exceeds a predetermined reference range (e.g., 1000 to 2500 ppm) as shown in Fig. 18 (S1801). S1802). In this case, ambient air flows into the thermo-hygrostat.

At the same time, the container exhaust is discharged to the outside through the total heat exchanger

At this time, the heat exchange module performs heat exchange between the inside air and the outside air, thereby minimizing heat loss.

As the outside air is introduced, the concentration of carbon dioxide inside the container gradually decreases. In this case, it is determined whether the carbon dioxide concentration is below the reference range (S1803). In such a case, the total enthalpy heat exchanger is turned off to shut off the inflow of the outside air, and the air is circulated between the thermo-hygrostat and the container (S1804).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be appreciated that one embodiment is possible.

Accordingly, the true scope of the present invention should be determined by the technical idea of the claims.
