Description

Ventilation windows with reflection switching

technical field

The utility model belongs to the technical field of building room ventilation, in particular to a ventilation window with a reflection switching function.

Background technique

With the improvement of people's material living standards, people have higher and higher requirements for the comfort of residential houses. Many high-end residential houses are equipped with fresh air systems to control the temperature and ventilation in the house. At the same time, according to the latest national standards for the design of heating, ventilation and air conditioning for civil buildings, it is clearly stipulated that all rooms in civil buildings need to consider the ventilation design requirements of a certain amount of fresh air, but at the same time, this action will bring untreated outdoor air into the room and The air stagnant in the room is exhausted to the outside, so that the air-conditioning equipment must additionally undertake the work of processing this part of the air, resulting in a considerable part of energy consumption.

In existing residential houses, air conditioners are generally installed for temperature control, but the air conditioners usually cannot meet the requirements of fresh air ventilation. In order to meet the requirements of fresh air ventilation in the building room, it is generally necessary to install fresh air fans. A fresh fan is an air conditioning device that can introduce fresh air into a room and purify it. Fresh air fans generally include two types of exhaust air fresh fans or air supply fresh air fans. When installing and using, it is generally used in the room to install the air conditioner and the air supply type fresh fan, or install the air conditioner and the exhaust type fresh fan in the room. When installing a ventilation-type new fan (referred to as a ventilation fan) in a room, the ventilation depends on the gap between the doors and windows of the room, while when installing an exhaust-type fresh fan (referred to as an exhaust fan), the ventilation depends on the gap between the doors and windows of the room. In order to avoid duplication of functions, it is generally not necessary to install both a supply fan and an exhaust fan in the room. In this way, relying on the air intake or exhaust from the gaps of the doors and windows of the room, the heat or cold energy in the exhaust air is often not fully utilized. At the same time, when the temperature difference between the inside and outside of the house is large, the window of the house becomes the concentrated location of heat exchange inside and outside the house, which will cause a large loss of heat or cold energy in the house from the position of the window, which is not conducive to the reduction of the overall temperature control energy load of the room.

In the prior art, some fresh air systems also have functions such as ventilation, temperature regulation, air filtration, and even humidity regulation. For example, the application number CN201410058724.1, a multifunctional fresh air blower disclosed in the patent document entitled "Multifunctional Fresh Air Fan and Its Application". Another example is a multifunctional fresh air blower disclosed in the patent document with the application number CN201611172058.X, entitled "a multifunctional fresh air blower". Another example is a multifunctional fresh air blower disclosed by CN209655509U for which the inventor has applied for a patent. However, the above-mentioned fresh fan systems have complex structures and high costs, and are generally used in large shopping malls and other places, but have not yet been popularized and applied in civilian residences. Moreover, these new fan systems still fail to solve the problem that the position of the window of the house will become the weak position of the room's thermal insulation, which will lead to the increase of the overall temperature control load of the room.

At present, some house windows are designed with double-glazed glass, which can have a certain thermal insulation effect. However, ordinary ventilation windows are mainly designed for sound insulation, and their heat transfer shielding effect is still relatively limited. The overall ventilation temperature control system produces more benefits. Chinese patent CN108193994A has disclosed a multi-functional double-glazed ventilation window, including double-glazed glass, energy recovery unit and automatic control unit, which can adjust the humidity, temperature and purification of outdoor fresh air or indoor return air, and also has shading and Noise reduction function to meet indoor air quality requirements. In this patent, it seems that various functions such as air purification, temperature adjustment, and humidity adjustment are arranged on the window, which improves the function of the window, but in fact, the glass window has its own functions of indoor lighting and perspective outside the house, as well as the installation location, Due to the limitation of size and other requirements, it is not suitable to directly integrate air purification, temperature adjustment, humidity adjustment and other functions on the window, and the corresponding indoor environment control effect is far less than the effect produced by the use of fresh fans and air conditioners. At the same time, after the interior of the double-layer glass is ventilated, it is only considered to rely on the electrostatic dust removal device to clean the glass cavity, and its cleaning effect is limited.

In order to solve the above problems, the inventor has also designed a double-glazed window and applied for a patent. The patent application number is 2020201702178. Its structure includes a rectangular window frame. The interior of the window frame is vertically fixed with double-glazed windows at front and rear intervals. , a ventilation inner cavity is formed between the double-layer glass, which is characterized in that the upper end of the window frame is also provided with an upper outer air duct that communicates outward to the outside and an upper inner air duct that communicates inward to the inner side. The upper outer air duct and the upper The inner air duct and the upper end of the ventilation cavity are communicated with each other, and an upper air duct switching device for controlling the on-off switching of the three is also arranged between the three; Inwardly connected to the lower inner air duct on the inner side, the lower outer air duct, the lower inner air duct and the lower end of the ventilation cavity are arranged in communication, and a lower air duct switching device for controlling the on-off switching of the three is also arranged between them.

In this way, the window can control the on-off and switching of the air duct through the upper air duct switching device and the lower air duct switching device, so as to be suitable for air intake and exhaust requirements in different situations. It can be used in conjunction with a supply-type fresh fan or an exhaust-type fresh fan to meet the requirements of indoor fresh air volume and reduce the energy consumption of indoor air conditioning. However, the double-glazed window simply uses the double-glazed glass as a ventilation channel, and its effect on indoor heat preservation and energy consumption reduction is still relatively limited, which needs to be further optimized and improved.

Therefore, the inventor considered to design a technology that can use windows for ventilation switching control, so that it can better reduce the heat transfer effect of the windows, improve the indoor thermal insulation performance, and reduce the overall energy consumption of the house temperature control system.

The indoor pressure is higher than the outdoor pressure, and the indoor air temperature is lower than the outdoor temperature. Adjust the louver device so that the reflection side of the glass louver faces the outside, and control the wind of the glass window. The duct switching realizes the exhaust, and the air duct is controlled so that the indoor air flows from the lower inner air duct through the outer ventilation cavity of the glass interlayer and then flows out from the upper outer air duct (see Figure 10). In this process, the indoor low-temperature air is discharged through the glass interlayer to cool the outer glass, reduce the rate of outdoor heat transfer inward through the glass window, and achieve the purpose of reducing the indoor cooling load; control the low-temperature air in the outer ventilation cavity between the glasses Flowing from the bottom to the top can better rely on the low-temperature air to take away the heat collected by the reflection of the glass louvers in the outer ventilation channel, and make better use of the cold air discharged from the outside to cool the window glass. That is to make full use of the cooling capacity of the outside air to reduce the temperature of the glass, and combined with the solar radiation reflection effect of the glass louvers, it can better reduce the heat transferred from the external sunlight to the room through the glass window.

More specifically, this method uses ventilation windows instead of traditional windows and doors for air exhaust, which can have the following advantages: 1) We use the useless cold air that should be exhausted to cool the glass, not will increase other energy consumption. 2) We retain the cooling capacity of this part of the air by strengthening the heat exchange between the air to be discharged indoors and the glass, and reduce the indoor load by reducing the temperature of the glass. achieve the purpose of energy saving. 3) By organizing the air to pass through the glass interlayer ventilation cavity, the air in the glass cavity channel is lower than the outdoor temperature, which can prevent the outdoor high temperature from being directly transmitted to the room, which is equivalent to an air curtain, reducing the indoor load and realizing energy saving. 4) The opening area of the ventilation window is fixed, and there is no problem that the size of the window opening area is not easy to grasp compared to opening the window for ventilation. 5) The flow of low-temperature air from the outer ventilation cavity can better take away the heat reflected by the glass louvers and concentrated in the outer ventilation cavity. Therefore, the combined effect of the cooling of the external cold air combined with the reflection of the glass louvers can make the window better. It has the effect of blocking indoor and outdoor heat transfer and reducing indoor heat insulation.

2. Indoor heating and ventilation mode in winter (see Figure 11) At this time, the air conditioning equipment is heating and heating, the blower is entering the air, the indoor pressure is higher than the outdoor pressure, and the indoor air temperature is higher than the temperature of the glass window and higher than the outdoor temperature. At this time, adjust the louver device to make The reflective side of the glass louver faces indoors, and the other side faces outdoors to absorb sunlight and heat. At the same time, it controls the switching of the glass window air duct to realize exhaust air, so that the indoor air flows from the lower inner air duct through the outer ventilation cavity of the glass interlayer, and then winds from the upper outer side. outflow. In this process, the indoor high-temperature air is discharged through the glass interlayer, heating the outer glass, reducing the rate of indoor heat transfer outward through the glass window, and achieving the purpose of reducing the indoor heat load. Flowing from bottom to top can better prevent the sunlight heat absorbed by the glass shutters from being taken away by the wind flow, which is more conducive to the transfer of the absorbed sunlight heat to the interior through the closed inner ventilation cavity, and makes better use of the heat discharged from the outside. The residual heat of the air heats the window glass to avoid the temperature of the window glass being too low and taking away the indoor heat. Better to keep indoors warm to reduce indoor heat load.

More specifically, this method uses ventilated windows instead of traditional windows and doors for air exhaust, which can have the following advantages: 1) We use the part of the useless hot air that would have been exhausted to heat the glass, and No other energy consumption will be added. 2) We retain the heat of this part of the hot air by strengthening the heat exchange between the air to be discharged indoors and the glass, and reduce the indoor load by heating the glass. achieve the purpose of energy saving. 3) By organizing the air to pass through the glass interlayer channel, the air in the channel is higher than the outdoor temperature, which can prevent the outdoor low temperature from being directly transmitted to the room, which is equivalent to an air curtain, reducing the indoor load and realizing energy saving. In this case, the thermal conductivity of our ventilation windows is better than that of ordinary double-layer windows. 4) The opening area of the ventilation window is fixed, and there is no problem that the size of the window opening area is not easy to grasp compared to opening the window for ventilation. 5) The indoor air is discharged through the outer ventilation cavity, which can better facilitate the transfer of the sunlight heat absorbed by the glass louvers to the room without being carried away by the wind.

In the second application mode, the window and the exhaust fan (that is, the exhaust fresh air fan) and the air-conditioning equipment are used in the same building room. The following operation control modes can be realized.

1. Indoor cooling and ventilation mode in summer (see Figure 12) At this time, the air conditioner is cooling, the indoor air temperature is lower than the glass window temperature and lower than the outdoor temperature, and the exhaust fan is turned on to exhaust air, and the indoor pressure is lower than the outdoor pressure; at this time, adjust the louver device to make The reflection side of the glass louver faces the outside, and at the same time, the air duct of the glass window is controlled to switch to realize the air intake, and the air duct is controlled so that the outdoor air enters the window from the lower outer air duct, and part of the air flows upward from the upper outer air duct through the outer ventilation cavity, and the other part of the air flows out from the upper outer air duct. Enter the room directly from the lower inner air duct. In this way, when the window glass is irradiated with strong solar radiation in summer, the heat will accumulate and the temperature will be higher than the outdoor air temperature. Therefore, part of the intake air enters the room directly from the lower end of the window to avoid passing through the ventilation cavity and being heated by the glass, which will increase the indoor load; A part of the incoming air is heated by the glass in the outer ventilation cavity and flows upwards and is discharged from the upper outer air duct. In this way, a wind flow that circulates outwards in the outer ventilation cavity can take away part of the heat of the glass. At the same time, the rising air in the outer ventilation cavity The airflow can further take away the heat gathered by the reflection of the glass louvers in the outer ventilation duct, so as to better achieve the effect of reducing the cooling load of the indoor air conditioner.

More specifically, this method has the following advantages over traditional doors and windows for air exhaust: 1) The opening area of the ventilation window is fixed, and the size of the window opening area is not difficult to grasp compared to opening the window for ventilation. question. 2) While meeting the demand for air supply, the external circulation of air in the outer ventilation cavity is formed, which cools the glass and cavity, reduces the load of indoor air conditioning, and achieves the goal of energy saving. 3) By organizing the air to pass through the vertical channel (that is, the ventilation cavity), the air temperature in the cavity is lower than the glass temperature, which can prevent the outdoor high temperature from being directly transmitted to the room, which is equivalent to an air curtain, reducing the indoor load and realizing energy saving. In this case, the comprehensive heat transfer coefficient of the ventilation window will not be worse than that of the ordinary sealed double-glazed window. 4) Part of the air circulating outward from the outer ventilation cavity can better take away the heat reflected by the glass louvers and concentrated in the outer ventilation cavity, so the windows can better block the heat transfer between indoor and outdoor. The effect of thermal derating.

2. Indoor heating and ventilation mode in winter (see Figure 13), at this time, the air conditioner is heating, the indoor air temperature is higher than the outdoor air temperature, the exhaust fan is turned on to exhaust air, and the indoor pressure is lower than the outdoor pressure; at this time, adjust the louver device to make the glass louver reflect One side faces indoors, and the other side faces outdoors to absorb sunlight and heat, and at the same time control the switching of glass window air ducts to achieve air intake, so that outdoor air enters from the lower outer air duct, flows upward through the inner ventilation cavity, and then flows into the room from the upper inner air duct . In this process, the outdoor low-temperature air enters the room through the glass interlayer, is preheated in the glass interlayer channel, and then enters the room after increasing the intake air temperature, and uses the window glass temperature to preheat the intake air to reduce the indoor heating load. The air flows from bottom to top between the glass through the inner ventilation cavity, and when there is sunlight, the solar heat absorbed by the glass louvers can be better brought into the room with the wind flow. Better reduction of indoor heating loads.

More specifically, this method has the following advantages compared with the traditional method of opening windows and doors for air intake: 1) The opening area of the ventilation window is fixed. The problem of opening the window for ventilation is easy to waste energy due to the inaccurate opening area of the window and cannot form an effective airflow organization. 2) The slightly heated air entering the room can reduce the discomfort of people compared with entering through the window seam: the wind directly infiltrating through the window seam will bring a strong sense of cold wind, which is very uncomfortable in winter. 3) Fresh cold air enters the room from above, and the air temperature above the room is relatively high. The heat transfer effect is better when the fresh air enters the room, and for this reason, the thermal comfort is also better. 4) The air flow entering the glass window flows into the room from the inner ventilation cavity, which can better transmit the sunlight energy irradiated on the glass into the room as much as possible, and better reduce the indoor air conditioning load.

The third application method is that the room is not installed with a fresh air fan. When the window is directly connected to the air conditioner in the same building room, directly open the upper, lower, inner and outer air ducts of the window to allow natural ventilation, see Figure 14-15. Compared with traditional doors and windows for ventilation, it has the following advantages: 1) The opening area of the ventilation window is fixed. 2) In summer, the outside ventilation duct can be opened again to realize the circulating flow of part of the air flow, which can better cool the glass windows and reduce the load of indoor air conditioning; achieve the goal of energy saving. 3) While meeting the demand for air supply, the method of setting the height of the two air vents, one in and one out, has a good power effect of hot pressing. It is conducive to the circulation of indoor and outdoor air. 4) It is rare for residents to open the windows when the air conditioner is turned on in their daily use. Because of this, there is a slight positive pressure in the room, and heat runs out of the room, causing waste, which is reflected in the increase in electricity consumption. But not opening the window does not meet the relevant fresh air volume specifications; if the window is opened, the ventilation efficiency is low, because the single-sided window is used as both an air inlet and an air outlet, and the effect is not good. This patent can effectively improve this problem.
