Conventionally, a night purge is known in which indoor air is replaced with outside air at night to remove odors and hot air trapped in the room to reduce the cooling start load in summer.
[0003]
In addition, it is known that a double window is provided in a building to increase heat insulation by an air circulation window that allows indoor air to circulate between the windows, thereby reducing the load during the peak cooling period and the load during winter heating.
[0004]
[Problems to be solved by the invention]
However, in the intermediate period between summer and winter, the heat distribution of the air flow window is high, and if the temperature of the outside air is lower than the temperature of the ceiling space, heat dissipation at night is hindered. There is a problem that the cooling load of the air conditioner used inside increases. The air circulation window with a night purge function according to the present invention is proposed in order to solve such a problem.
[0005]
[Means for Solving the Problems]
The gist for solving the above-mentioned problem of the air flow window with night purge function according to the present invention is a double window provided in a window opening of a building, and an exterior and a ceiling provided in an upper wall part of the double window. together with at least and a night purge opening for communicating the back space,

[0007]
According to the air circulation window with a night purge function according to the present invention, outside air having a temperature lower than the ceiling temperature is introduced into the ceiling space at night even in an intermediate period between summer and winter in a building having the air circulation window. Thus, it becomes possible to reduce the cooling load during the day. As a result, an energy saving effect can be obtained from summer to winter.
[0008]
In addition, by using the exhaust fan for the air distribution window and forcing outside air into the ceiling space from the night purge opening, the amount of outside air can be reliably expected. Furthermore, the night purge can be performed most efficiently and automatically by measuring the outside air temperature or outside air temperature humidity and the temperature or temperature and humidity of the ceiling space with the control device and controlling the opening and closing of the damper.

The control device 16 performs night purge according to the difference between the outside air enthalpy detected by the temperature / humidity sensor 18 and calculated by the control device 16 and the enthalpy in the ceiling.
[0015]
The control device 16 activates the opening / closing device 9a to open the opening / closing lid 9. At the same time, the night purge damper 19 is opened, the air conditioning damper 20 is closed, the exhaust fan inverter 21 is driven, and the exhaust fan 22 is activated. To do.
[0016]
As a result, as shown in FIG. 4, outside air having a low temperature enters from the opening 8 and reaches the ceiling space 7 through the space 8a. The hot air in the ceiling space 7 is exhausted from the exhaust pipe 15 to the outside through the exhaust duct 14 and the exhaust fan 22. In this way, the ceiling space 7 is replaced with hot air and filled with outside air having a low temperature.
[0017]
As the temperature of the ceiling space 7 decreases, the temperature of the room 23 also decreases through the ceiling 7a or the floor slab 13. Thus, the cooling load is reduced when the air conditioner is operated during the daytime.
