Container with device preventing dew condensation
First Claim
1. A container for goods comprising:
- a container body having a generally rectangular parallelepiped shape with outer walls defining a space therein for storing goods;
said outer walls also defining an intake opening for an introduction of atmospheric air into the space of the container and an exhaust opening for a removal of the air from the space of the container to the atmosphere;
the intake and the outlet openings being provided at different locations inside the container;
a fan for generating a forced flow of the air from the intake opening to the exhaust opening via the space of the container;
a sensor for detecting a temperature inside the container and issuing electric signals indicating the detected temperature;
determining means for determining if a change in the detected temperature over a unit of a time is larger than a predetermined value, and;
control means for operating the fan when the determining means determines a condition of the detected temperature over a unit of a time being larger than a predetermined value.

Abstract
A ventilation apparatus for a container for transporting goods by truck or ship. The walls of the container are provided with an inlet opening and an outlet opening, and an inlet unit is connected to the inlet opening and an outlet unit is connected to the outlet opening. The outlet unit is provided with a battery-operated fan for a forced ventilation of the container, temperature sensors are provided for detecting the inner wall temperature and inner air temperature, and a degree of change in the wall temperature per unit of time is calculated for operating the fan when the degree of change in the wall temperature is larger than a predetermined value. Furthermore, the difference between the inner air temperature and the wall temperature is calculated, and the fan is operated when that difference is larger than a predetermined value.

14. A container for goods comprising:
-
a container body having a generally rectangular parallelepiped shape with outer walls defining a space therein for storing goods; said outer walls also defining an intake opening for an introduction of atmospheric air into the space inside the container, and an exhaust opening for a removal of the air from the inside space of the container to the atmosphere; the intake and the outlet openings being provided at different locations on the walls; a fan for generating a forced flow of an air from the intake opening to the exhaust opening via said inside space of the container; a first temperature sensor for detecting a temperature at the walls of the container; a second temperature sensor for detecting a temperature of the air inside the container; first determining means for determining a condition if the wall temperature detected by the first sensor is lower than a predetermined value with respect to the air temperature detected by the second sensor; second determining means for determining a condition if a change in the wall temperature detected by the first sensor means for a unit of a time is larger than a predetermined value, and; control means for operating the fan when one of the first determining means and the second determining means determines the condition.
