Conventionally, a planned ventilation system has been adopted which performs efficient forced ventilation by discharging polluted air and humidity in each room to the outside through a predetermined route. The planned ventilation system was developed for a house in a cold district where the air temperature in the interior space of the house (hereinafter referred to as the inside air temperature) is higher than the outside air temperature (hereinafter referred to as the outside air temperature) due to heating. . In a conventional planned ventilation system, when the inside air temperature is higher than the outside air temperature, the air outlet from the outside air (hereinafter simply referred to as “air supply”) is taken into consideration, taking into consideration that the chimney effect causes levitation force in the inside air. Is fixed to the lower part of the living space or the underfloor space, or in consideration of the downward force acting on the air supply when the air supply temperature is lower than the inside air temperature, the air supply outlet should be located above the living space. It was fixed to the part.

する強制給気装置を提供することを目的とする。In recent years, high heat insulation airtightness has been required even in houses in warm regions, and as a result, planned ventilation systems have also been adopted in houses in warm regions. It was However, if the planned ventilation system in which the air supply outlet is fixed to the lower part of the living space is applied to a house in a warm region, the inside air temperature becomes lower than the outside air temperature due to cooling, and in the summer when the downward force acts on the inside air, There is a problem in that the air supply cannot be raised due to being pushed by the descending air flow, and eventually the living space cannot be sufficiently supplied. In addition, if the planned ventilation system with the air supply outlet fixed to the underfloor space is applied to a house in a warm region, hot and humid air supply is released into the underfloor space at a relatively low temperature in summer, and the wooden parts and Condensation forms on the surface of the iron member, which causes a problem of causing deterioration of the wooden member and the iron member. On the other hand, if the planned ventilation system with the air supply outlet fixed to the upper part of the living space is applied to a house in a warm region, the temperature difference between the inside air and the outside air is much smaller in winter than in a cold region. However, there is a problem in that the supply air cannot be lowered by being pushed by the upward airflow of the inside air generated by the chimney effect, so that the living space cannot be sufficiently supplied. The present invention, when the inside air temperature is higher than the outside air temperature, an ascending airflow of the inside air occurs, and when the inside air temperature is lower than the outside air temperature, focusing on the occurrence of a descending airflow of the inside air, the winter By changing the location of the supply of air in the summer, the efficiency of forced air supply is improved both in the winter and in the summer, and the condensation caused by air supply in the summer is prevented, so that not only the houses in cold regions but also in warm regions It is an object of the present invention to provide a forced air supply device that constitutes a planned ventilation system that can be applied to other houses without any problems.
