Description

Installation method of energy-saving window combined with vacuum layer and troposphere

technical field

The invention belongs to the field of building energy conservation, and in particular relates to an energy-saving window combined with a vacuum layer and a troposphere layer of a triple-glazed window and an installation and use method thereof. the

Background technique

Building energy consumption accounts for about a quarter of the total energy consumption of the whole society, and air conditioning energy consumption in summer and heating energy consumption in winter are the main components. In air conditioning and heating loads, windows have a relatively strong heat transfer effect. For example, in summer, the outdoor solar radiation shines into the room through the window, increasing the cooling load of the air conditioner, and at the same time, the outdoor convective hot air is conducted to the room through the glass, further increasing the load, thereby increasing power consumption; in winter, the outdoor air temperature is lower than the indoor air, and the heat Conducted to the outside through the glass, resulting in the loss of indoor heat. Therefore, the reasonable design of windows directly affects the effect of building heat insulation in summer and winter heat preservation, which in turn affects building energy consumption. the

The previous energy-saving windows can be roughly divided into three types: radiation-reducing type, which reduces the amount of solar radiation entering the room in summer, and the disadvantage is that it blocks solar radiation in winter and reduces the supplementary effect of solar radiation on indoor heating; The convective heat exchange type is generally double-glazed, and the middle is either filled with air or vacuum. The disadvantage is that summer radiation can not solve the problem of increasing indoor air conditioning load in summer; the ventilation (breathing) window type is also double-glazed, and the upper and lower parts are equipped with Ventilation holes use convection to exchange air to dissipate heat. The disadvantage is that it cannot solve the problem that the air convection heat transfer in the interlayer increases the indoor heat load in summer and the indoor cooling load in winter, that is, the effect of heat insulation in summer and heat preservation in winter is not good. good. the

Based on the above reasons, there is an urgent need to invent a new type of window that integrates the advantages of the above various types of windows and overcomes its shortcomings, so as to meet the needs of building energy conservation. the

Contents of the invention

The first purpose of the present invention is to solve the above-mentioned defects in the prior art, to provide a vacuum layer and vacuum layer based on the three heat transfer modes of radiation, convection and heat conduction, which combine the three functions of radiation, convection and vacuum heat insulation. Troposphere combined energy-saving windows. the

The first object of the present invention is achieved through the following technical scheme: the combined vacuum layer and troposphere energy-saving window, which includes vacuum laminated outer glass, intermediate glass, convective laminated outer glass, and vacuum interlayer The outer glass and the middle glass form a closed vacuum interlayer, and the middle glass and the convection interlayer outer glass form a ventilated convective layer; there is a ventilation hole slot on the upper part of the vacuum interlayer between the upper window frame and the upper part of the vacuum interlayer, and the upper window outside the slot The upper part of the vacuum interlayer ventilation slot switch plate is arranged on the frame; an upper ventilation hole slot of the convection interlayer is arranged between the upper window frame and the upper part of the outer glass of the convection interlayer, and the upper window frame outside the slot is provided with an upper ventilation hole of the convection interlayer Slot switch plate; a ventilation hole slot for the lower part of the convection interlayer is provided between the lower window frame and the lower part of the outer glass of the convection interlayer, and a lower window frame outside the slot is provided with a switch plate for the lower ventilation hole of the convection interlayer. the

The second object of the present invention is to provide the method for installing and using the combined energy-saving window of the above-mentioned vacuum layer and troposphere, which includes the following contents:

(1) In the hot summer, install the outer glass of the vacuum interlayer facing indoors and the outer glass of the convection interlayer facing outdoors; close the upper ventilation slot switch board of the vacuum interlayer, open the upper ventilation slot switch board of the convection interlayer and the lower part of the convection interlayer for ventilation Slot switch plate;

(2) During the spring and autumn transitional season, install the outer glass of the vacuum interlayer facing indoors and the outer glass of the convection interlayer facing outdoors; close the upper ventilation hole switch panel of the convection interlayer, open the lower ventilation hole switch panel of the convection interlayer and the upper part of the vacuum interlayer Vent slot switch panels; alternatively, open all vent slot switch panels;

(3) In the cold winter, install the outer glass of the convection interlayer facing indoors and the outer glass of the vacuum interlayer facing outdoors; close the upper ventilation slot switch board of the vacuum interlayer, open the upper ventilation slot switch board of the convection interlayer and the lower part of the convection interlayer for ventilation Slot switch plate;

Alternatively, install the outer glass of the vacuum interlayer toward the interior and the outer glass of the convection interlayer toward the outside; then close the upper ventilation hole slot switch board of the convection interlayer, the lower ventilation hole slot switch board of the convection interlayer and the upper ventilation hole slot switch board of the vacuum interlayer.

The present invention has the following beneficial effects:

(1) In the hot summer, the radiation load caused by solar radiation entering the room can be reduced by convection, and the direct convection and heat conduction of the outdoor hot air can be eliminated through the vacuum interlayer, that is, radiation is weakened and convection is isolated.

(2) During the transitional season, the air in the air convection interlayer is heated by solar radiation, the upper and lower ventilation slots are opened, and the thermal lift of the air is used for natural ventilation, so as to improve the indoor air quality. the

(3) In the cold winter, it not only maintains airtightness and heat preservation, but also uses solar radiation to heat the indoor air. When winter comes, turn the window 180 degrees horizontally relative to the installation state in summer, and then install it on the window frame. After such installation, the convection of the cold outdoor air and the heat conduction of the glass are all isolated by the vacuum layer, while the solar radiation can pass through the vacuum layer, and the heat in it is attracted by the indoor air to achieve the function of heating the indoor air. the

(4) In the cold season, if the reverse installation is difficult or labor-intensive, you can directly close all the ventilation slots to achieve the effect of heat preservation. Its function is similar to that of three layers of insulating glass, but it cannot use solar radiation to heat the indoor air. the

(5) Through the combination of vacuum interlayer and air convection interlayer, as well as front and back installation in different seasons, the purpose of rational use of solar radiation is achieved. the

Air vent slot switch plate 9 in the lower part of the interlayer. When the sun shines on the window, firstly, the radiant energy is divided into three parts, which are reflected, absorbed and transmitted by the outer glass of the convection interlayer respectively; secondly, the transmitted radiant energy is reflected, absorbed and transmitted by the middle glass. During this process, the energy reflected and absorbed by the middle glass, and the heat absorbed by the outer glass of the convection interlayer jointly heat the air in the ventilated troposphere, thereby generating thermal pressure.
