Concerning window exhaust equipment. Note that the term "window" as used in this text includes not only general windows but also windows that are part of a curtain wall.

が消費される。 BACKGROUND OF THE INVENTION Buildings have traditionally been provided with windows for the purpose of providing sunlight and views, and in office buildings and the like, air conditioning maintains the indoor temperature at a constant temperature. However, during cooling, heat enters from outside, and during heating, heating heat escapes from inside the room, so excess energy is consumed for air conditioning due to this heat entering and exiting through windows.

を少なくする工夫がなされていた。 Blinds have traditionally been used to prevent heat from entering a room due to direct sunlight. In addition, by using double-glazed windows, an air layer is formed between the double panes of glass to reduce the amount of heat entering and exiting the windows.

用量の増大は避けられなかつた。 However, these methods do not sufficiently improve the thermal environment inside the room, especially near the windows, and when considering radiant heat in addition to the indoor air temperature, the temperature felt by the human body (hereinafter referred to as effect), which is composed of the indoor air temperature and the average radiant temperature. This has resulted in an increase in the cooling period (referred to as temperature) and a decrease in the heating period, leading to an unavoidable increase in the amount of energy used for air conditioning.

た。 In other words, by using blinds inside the window or between double panes of glass during cooling, direct sunlight can be prevented from entering the room, but solar heat rays that are irradiated directly to the blinds and diffused into the atmosphere can be used to irradiate the room indirectly. The blinds are heated by the heat rays of the sky light,
If the blinds are inside the room, the heat radiated from the blinds and the heat transferred from the blinds to the indoor air, and if the blinds are located between double panes of glass, the heat is radiated from the blinds and the air between the double panes of glass is generated by the blinds. The indoor glass was heated by the heating, and heat entered the room due to radiant heat from the indoor glass and heat transfer to the indoor air. Also, even when there is no direct sunlight,
If there were no blinds, the temperature of the indoor glass would rise through the outdoor glass heated by the heat rays of the sky light and the outside temperature, so even if blinds were used, heat would still infiltrate as described above. In addition, especially during winter heating, there is generally a large temperature difference between indoors and outdoors, and even if the window is double-glazed, the indoor glass becomes cold due to heat transfer and radiation through the air layer between the outdoor glass and the double-paned glass. Therefore, the radiant heat from objects and human bodies inside the heated room is absorbed by the cooled indoor glass and radiated away. As a result, in the past, it was unavoidable that the working temperature near the window would rise during the cooling period and fall during the heating period.

である。 This invention effectively utilizes the exhaust of indoor air to the outdoors for ventilation, which was also required for air conditioning in conventional buildings, thereby lowering the working temperature inside the window during the cooling period and heating the room. The purpose is to provide a window that can be raised to reduce energy consumption for air conditioning. That is, by exhausting indoor air during the cooling period and heating period through the space formed between the inner and outer double glass, the indoor glass is cooled by the conditioned indoor air during the cooling period,
During the heating period, indoor air is heated to lower or increase the operating temperature near the window, thereby reducing the amount of energy consumed for air conditioning.
