Abstract

PURPOSE:To reduce the energy consumption for air conditioning by a method wherein the operative temperature at a window in the interior of a room is controlled by utilizing the exhaustion of room air for ventilation in a building. CONSTITUTION:A spiral, cylindrical casing 13, on the peripheral surface of which a blowing-off port 12 is provided, and a cylindrical suction casing, on the peripheral surface of which a suction port is provided, of a centrifugal blower 9 are formed coaxially with respect to the driving shaft 15 of the centrifugal blower 9 and at the same time respectively and independently pivotally formed about the driving shaft 15 in the air space 7 of a double window formed between two pairs of double glasses 5 respectively arranged on the inside and outside of a room. By exhausting room air through the space formed between the inside and outside double glasses during cooling season and heating season, the operative temperature near the window is lowered or raised, resulting in reducing the energy consumption for air conditioning.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to air conditioning of buildings, and improves the thermal environment especially near windows by ventilating indoor air using windows.
This invention relates to a window exhaust system that reduces the indoor heating and cooling load. Note that the term "window" referred to in this text includes not only general windows but also windows that are part of a curtain fall.

Traditionally, buildings have been provided with windows for the purpose of lighting and views, and in office buildings, air conditioning maintains the indoor temperature at a constant temperature. However, when cooling, heat enters from outside, and when heating Because of the escape of heating heat from the windows, extra energy is consumed for air conditioning by passing this heat in and out through the windows.

Traditionally, blinds have been used to prevent heat from entering the room due to direct sunlight. By using double-glazed windows, an air layer was formed between the double panes of glass to reduce the amount of heat entering and exiting the window. is not sufficiently improved, and when radiant heat is considered in addition to the indoor air temperature, the temperature felt by the human body (hereinafter referred to as the working temperature), which is composed of the two indoor air temperatures and the average/average resistance temperature, during the cooling period. In other words, by using blinds inside windows or between double panes of glass during cooling, solar heat rays can be reduced indoors by using blinds during cooling. However, if the blind is heated indoors by the solar heat rays that shine directly on the blind and the heat rays of sky light that diffuses into the atmosphere and directly irradiates the blind, Due to the heat radiated from the blinds and the heat transferred from the indoor air through the blinds, or if the blinds are located between double panes of glass, the heat radiated from the blinds and the heating of the air between the double panes of glass by the blinds causes was heated, and heat entered the room due to radiant heat from the indoor glass and heat transfer to the indoor air. In addition, even if there is no direct solar radiation, if there are no blinds, the heat rays from the sky light and the outside temperature will pass through the outside glass heated by the outside temperature, and the temperature of the indoor glass will rise, even if blinds are used. Similarly, there was an intrusion of heat. In addition, especially during winter heating, there is generally a large temperature difference between indoors and outdoors, and even if the window is double-paned (°C), the indoor glass will be at a low temperature due to heat transfer and radiation through the air space between the outdoor glass and the double-glazed glass. Therefore, the radiant heat from objects and human bodies inside the heated room is absorbed by the cooled indoor glass and radiated away by °C. As a result, in the past, it was unavoidable that the operating temperature near the window would rise during the cooling period and fall during the heating period.

On the other hand, in buildings such as buildings where many people live, the amount of ventilation required per person is regulated, and traditionally indoor air conditioning was ventilated outdoors by some method. Ta.

The present 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 operating temperature inside the window during the cooling season, and reducing the temperature during the heating period. The purpose is to provide a window that can be raised to reduce energy consumption for air conditioning. In other words, by venting indoor air throughout the space formed between the inside and outside double windows and during the cooling and heating periods, the indoor glass is cooled by the conditioned indoor air during the cooling period, and by the indoor air during the heating period. This is an exhaust system used to reduce or increase the operating temperature near the window by heating it, thereby reducing the amount of energy consumed for air conditioning.

The present invention is an exhaust device for use in a window in which glass is disposed on the outside of a room and a space is formed between the two glasses, and the invention is an exhaust device for use in a window in which glass is arranged on the outside and the outside of the room to form a space between the two glasses. A cylindrical casing and a cylindrical suction casing having a suction port on the circumference are arranged in series parallel to the glass surface, and both casings are coaxial with the drive shaft of the centrifugal blower. The present invention also provides an exhaust device for use in a window that is formed to be rotatable with respect to the drive shaft and that reduces air conditioning energy consumption.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. As shown in Figures 1 to 3, an upper frame 1. Bottom frame 2. Upper horizontal beams 4 A and 4 are installed on the outside and inside of the rectangular window frame that forms the bottom of the tank with the vertical frame 3 and the vertical frame 3 , respectively. A glass 5 is placed between both horizontal bars 4A, 4B, vertical frame 3 and bottom frame 2.
A space 71 between the inner shoji 6A and 6B within the window frame mentioned above is fitted with the sliding shoji 6A and 6B, respectively.
The blind 8 is hung from 73. The blind may be a normal one for blocking light, or a blind that can collect solar heat as shown in Japanese Patent No. 1087042. In addition, although Venetian blinds are shown in the illustrated embodiment,
It can also be rolled blind.

A centrifugal blower unit is installed between the upper horizontal bars 4A and 4B and the upper frame 1 and vertical frame 3) Set up e. A centrifugal blower unit is a blower that rotates air at high speed and sends it out using the centrifugal force of the centrifugal force.The centrifugal blower unit has a cylindrical suction casing 11 with a suction port 10' on the circumference, and a vortex with an air outlet 12 on the circumference. In this embodiment, the cylindrical casings 13 are arranged in series parallel to the glass surface, and are coaxial with the drive shaft 15 which is rotationally driven by the motor 14 on both the casings 11 and 13'. Arranged so that it can freely rotate once per 15 seconds. The two casings 11 and 13 are supported by a radial bearing Y with respect to the shaft 15. When the drive shaft 15 rotates, the blades 16 within the spiral cylindrical casing 13 rotate in the direction of arrow 17.

As the blade 160 rotates, air enters the casing 11 through the suction port 10, and further flows into the center of the spiral casing 13 coaxial with this, and while passing through the rotating blade 16, it receives energy from the VC# blade and performs rotational movement at °C. This occurs and flows out of the casing 1 through the outlet 12. In this embodiment, tooth shapes 19a and 18a'i are formed on the outer periphery of the cylindrical casings 11 and 13.

The pinions 18 and 19 meshed with this are rotated rA by hand or electrically.
