Abstract

A container for a refrigerating machine has: a storeroom storing a stored objective; a housing chamber housing an evaporator and an evaporator fan and guiding an inside air in the storeroom to flowing back to the storeroom after passing through the evaporator; a first ventilation duct connected to the housing chamber and having a first blower fan and a first heat storage body; a second ventilation duct connected to the housing chamber and having a second blower fan and a second heat storage body; and a controller controlling the first blower fan and the second blower fan. The controller controls the first blower fan and the second blower fan and switches between (i) a mode in which an outside air inflows through the first ventilation duct, and the inside air outflows through the second ventilation duct and (ii) a mode in which an outside air inflows through the second ventilation duct, and the inside air outflows through the first ventilation duct, at a specified time interval.

First claim

The invention claimed is:

1. A container for a refrigerating machine comprising:
a storeroom storing a stored objective;
a housing chamber housing an evaporator and an evaporator fan and guiding an inside air in the storeroom to flowing back to the storeroom after passing through the evaporator;
a first ventilation duct having a first blower fan, a first heat storage body, and a first connecting port, the first ventilation duct being connected to the housing chamber through the first connecting port;
a second ventilation duct having a second blower fan, a second heat storage body, and a second connecting port, the second ventilation duct being connected to the housing chamber through the second connecting port; and
a controller controlling the first blower fan and the second blower fan, wherein
the controller controls the first blower fan and the second blower fan and switches between (i) a mode in which an outside air inflows through the first ventilation duct, and the inside air outflows through the second ventilation duct and (ii) a mode in which an outside air inflows through the second ventilation duct, and the inside air outflows through the first ventilation duct, at a specified time interval,
the first connecting port and the second connecting port are arranged to be parallel with each other in a flow direction of air flowing in the housing chamber, and
the first ventilation duct and the second ventilation duct are located on a same level in a vertical direction.

2. The container for a refrigerating machine according to claim 1 , further comprising
a gas concentration detector detecting a gas concentration of the inside air, wherein
the controller regulates the gas concentration to be kept at an optimum gas concentration that is optimum for the stored objective by controlling the first blower fan and the second blower fan.

3. The container for a refrigerating machine according to claim 1 , wherein
each of the first heat storage body and the second heat storage body has a length that is longer than or equal to 150 mm and shorter than or equal to 200 mm in a flow direction of the outside air or the inside air, and
each of the first heat storage body and the second heat storage body includes a latticed part having a hydraulic diameter that is longer than or equal to 1.5 mm and shorter than or equal to 2.0 mm and a thickness that is longer than or equal to 0.3 mm and shorter than or equal to 0.4 mm.

4. A container for a refrigerating machine comprising:
a storeroom storing a stored objective;
a housing chamber housing an evaporator and an evaporator fan and guiding an inside air in the storeroom to flowing back to the storeroom after passing through the evaporator;
a first ventilation duct connected to the housing chamber and having a first blower fan and a first heat storage body;
a second ventilation duct connected to the housing chamber and having a second blower fan and a second heat storage body; and
a controller controlling the first blower fan and the second blower fan, wherein
the controller controls the first blower fan and the second blower fan and switches between (i) a mode in which an outside air inflows through the first ventilation duct, and the inside air outflows through the second ventilation duct and (ii) a mode in which an outside air inflows through the second ventilation duct, and the inside air outflows through the first ventilation duct, at a specified time interval,
each of the first blower fan and the second blower fan is arranged to guide the outside air to inflowing when operated,
the first ventilation duct and the second ventilation duct are located on a same level in a vertical direction,
in the mode in which the outside air inflows through the first ventilation duct, and in which the inside air outflows through the second ventilation duct, only the first blower fan is operated, and the second blower fan is stopped, and
in the mode in which the outside air inflows through the second ventilation duct, and in which the inside air outflows through the first ventilation duct, only the second blower fan is operated, and the first blower fan is stopped.

5. The container for a refrigerating machine according to claim 1 , further comprising
a door closing the first ventilation duct and the second ventilation duct.

6. The container for a refrigerating machine according to claim 2 , wherein
the gas concentration detector detects a carbon dioxide concentration or an oxygen concentration of the inside air or detects both of the carbon dioxide concentration and the oxygen concentration of the inside air.

7. The container for a refrigerating machine according to claim 2 , wherein
the gas concentration detector detects a carbon dioxide concentration,
the first blower fan and the second blower fan are stopped when the carbon dioxide concentration detected by the gas concentration detector is lower than a specified first threshold value, and
the first blower fan and the second blower fan are operated when the carbon dioxide concentration detected by the gas concentration detector is higher than or equal to a specified second threshold value.

8. The container for a refrigerating machine according to claim 2 , further comprising
a door closing the first ventilation duct and the second ventilation duct, wherein
the gas concentration detector detects a carbon dioxide concentration,
