Embodiment 1

[0046] Example 1: The structure of energy-saving windows

[0047] see figure 1 and figure 2 The energy-saving window described in this embodiment includes a rotating window frame 1, a casement window frame 2, a fixed window frame 3, a hinge 4 and a rotating shaft 5, and one side of the casement window frame 2 is installed on the Inside the fixed window frame 3, the casement window frame 2 rotates 90° around the two hinges 4, the central axis of the rotating window frame 1 coincides with the central axis of the casement window frame 2, and the rotating window frame 1 and the casement window frame 2. Connected by two rotating shafts 5 placed on the central axis, the rotating window frame 1 can rotate 360° in the casement window frame 2 with the rotating shaft 5 as the center line, wherein:

[0048] The rotating window frame 1 includes an air vent 101, a lock slot 102, a turning page 103, heat-absorbing glass 104 and ordinary glass 105, and the heat-absorbing glass 104 and ord...

Embodiment 2

[0079] Example 2: Optimizing and screening the thickness of the air interlayer, the thickness of the heat-absorbing glass, and the size of the vent

[0080] The dry-bulb temperature and solar radiation at 12:00 noon on January 31 in a typical meteorological year in Lhasa are selected as the outdoor meteorological parameters for steady-state simulation, and the rest are the same as the above conditions.

[0081] (1) Air interlayer thickness

[0082] Choose 6mm ordinary colorless glass, 6mm heat-absorbing glass, and vents with length×width dimensions of 300mm×150mm, and simulate the working conditions with air interlayer thicknesses of 6mm, 12mm and 16mm respectively, and the results are shown in Table 3:

[0083] Table 3 Heat supply of vents under different air layer thicknesses

[0084]

[0085] It can be seen from the above table that the heat supply of the ventilation opening is the largest when the thickness of the air space is 12mm, and the heat supply is 291W, so the ...

Embodiment 3

[0098] Example 3: Taking Lhasa City as an example, the window with the optimal size structure in Example 2 was compared with the ordinary window to simulate the energy saving in winter

[0099]Using the optimized energy-saving window model in Example 2 to simulate the heat transfer throughout the day in winter conditions, compare the heat transfer of a single window frame with the same specification of 1800mm in height and 900mm in width, using ordinary 6mm transparent glass.

[0100] like Image 6 , Figure 8 As shown, the vents are opened from 7:00 to 17:00. Due to the action of solar radiation, the air layer is heated to form thermal convection. The vents on the upper part of the heat-absorbing glass supply heat to the room, and the wind speed of the vents follows the heat supply to the sun. As the radiation increases, the wind speed and heat supply both reach the maximum around 13:00, which are 0.54m / s and 349W respectively. At this time, the total heat transfer also reac...

Abstract

The invention relates to an energy-saving window. The energy-saving window comprises a rotary window frame, a casement window frame and a fixed window frame, wherein the casement window frame is installed in the fixed window frame, the rotary window frame is installed in the casement window frame, ordinary glass and heat absorption glass are installed in the rotary window frame, an air interlayer is formed by the ordinary glass, the heat absorption glass and the rotary window frame, ventilation holes are formed in the upper portion and the lower portion of the heat absorption glass respectively, and air in the air interlayer and indoor or outdoor air are exchanged through the ventilation holes. When solar radiation is strong in summer, the rectangular ventilation holes in the upper end and lower end of the heat absorption glass are opened, the heat absorption glass is made to face outdoors, and the interior of a room is isolated from heat and cooled; when the light condition is good in winter, the rectangular ventilation holes in the upper end and lower end of the heat absorption glass are opened, the heat absorption glass is made to face indoors, and the interior of the room is heated and the temperature of the interior of the room is increased through the heat absorption effect of the heat absorption glass and the thermal pressure ventilation effect of the air interlayer.

Description

technical field [0001] The invention belongs to the technical field of energy-saving of building envelope structures, relates to energy-saving optimization of building exterior windows, and particularly relates to an energy-saving window. Background technique [0002] Building energy consumption is an important part of social energy consumption, accounting for more than 30% of total social energy consumption. With the improvement of people's living standards, the proportion of building energy consumption will increase further. Building energy conservation has become one of the important links in my country's construction of a low-carbon economy, fulfilling energy conservation and emission reduction goals, and maintaining sustainable economic development. In the building envelope, windows, as one of the important means of lighting and ventilation, are the major contributors to the heat loss of the envelope. Therefore, windows play an extremely important role in building ener...
