Description

Ventilation window with reflection switching function

Technical Field

The utility model belongs to the technical field of building room ventilation, concretely relates to ventilation window with function is switched in reflection.

Background

With the improvement of the living standard of people, the comfort requirement of people on residential houses is higher and higher. A fresh air system is installed in many high-grade residential houses, and the temperature and ventilation in the houses are regulated and controlled. Meanwhile, according to the clear regulations of the heating ventilation and air conditioning design specifications of the civil buildings in the latest national standard, the ventilation design requirements of a certain fresh air volume are required to be considered for all the rooms of the civil buildings, but the air which is not processed outdoors is sent into the rooms and the air which is retained indoors is discharged outdoors, so that the air conditioning equipment needs to additionally bear the work of processing the air, and a considerable part of energy consumption is generated.

The existing residential houses are generally provided with air conditioners for temperature control, but the air conditioners can not meet the requirements of fresh air ventilation. The building room needs to meet the requirements of fresh air ventilation, and a fresh air machine is generally required to be installed. The fresh air machine is an air conditioning device which can introduce fresh air into a room and perform purification treatment. The new blower generally includes an exhaust type new blower or an air supply type new blower. When the air conditioner is installed and used, the air conditioner and the air supply type fresh air fan are generally installed in a room and used together, or the air conditioner and the air exhaust type fresh air fan are installed in the room and used together. When installing the air supply type fresh air blower (for short, blower) in the room, the air is discharged through the gap between the door and the window of the room, and when installing the exhaust type fresh air blower (for short, exhaust blower), the air is supplied through the gap between the door and the window of the room. In order to avoid the function repetition, a blower and an exhaust fan are not installed in a room at the same time. Therefore, heat energy or cold energy in the discharged air cannot be fully utilized by air intake or air exhaust through the gaps of the doors and the windows of the room. Meanwhile, when the temperature difference between the inside and the outside of the house is large, the window of the house becomes the heat exchange concentrated position inside and outside the house, so that the heat energy or the cold energy in the house can generate large loss from the window position, and the reduction of the whole temperature control energy consumption load of the room is not facilitated.

In the prior art, some fresh air systems have the functions of ventilation, temperature regulation, air filtration, even humidity regulation and the like at the same time. Such as the one disclosed in patent document No. CN201410058724.1 entitled "multifunctional fresh air machine and its applications". Also disclosed in the patent document entitled "a multifunctional fresh air machine" having application number cn201611172058. x. For another example, the inventor has applied for patent CN209655509U to disclose a multifunctional fresh air machine. However, the new fan systems have complex structures and high cost, are generally adopted in places such as large markets and are not popularized and applied in civil houses. And these new fan systems still fail to solve the room window position and can become the weak position of room heat preservation, and then lead to the problem that the whole control by temperature change load in room improves.

At present, some house windows have adopted the double glazing design, can have certain cold-proof effect, but more leading for the design that gives sound insulation of ordinary ventilation window, and its heat transfer shielding effect is still comparatively limited, does not possess ventilation effect simultaneously yet, is difficult to produce more profitability in the whole ventilation temperature control system in room. Chinese patent CN108193994A has disclosed a multi-functional double glazing ventilation window, including double glazing, energy recuperation unit and automatic control unit, can carry out humidifying, temperature regulation and purification to outdoor new trend or indoor return air, still has sunshade and falls the function of making an uproar simultaneously, satisfies the indoor air quality requirement. Look like all setting up multiple functions such as air purification, temperature regulation, humidity control on the window in this patent, improved window functionality, actually glass window has daylighting and the outdoor function of perspective and mounted position, requirement restriction such as size in its own room to be not fit for directly integrating functions such as air purification, temperature regulation, humidity control on the window, its indoor environmental control effect that corresponds is also far less than the effect that adopts new fan and air conditioning equipment to produce. Meanwhile, after the interior of the double-layer glass is ventilated, only the cleaning of the inner cavity of the glass is realized by the electrostatic dust removal device, the cleaning effect is limited, and the problems of poor perspective and lighting effect caused by difficult cleaning of the inner cavity of the glass after long-term use exist.

In order to solve the above problems, the inventor has also designed a double-glazing window and applied for a patent, the patent application number is 2020201702178, the structure of the double-glazing window comprises a rectangular window frame, double-glazing is vertically and fixedly arranged in the window frame at intervals from front to back, and a ventilation cavity is formed between the double-glazing, the double-glazing window is characterized in that the upper end of the window frame is also respectively provided with an upper outer air duct communicated to the outside outwards and an upper inner air duct communicated to the inside inwards, the upper outer air duct, the upper inner air duct and the upper end of the ventilation cavity are communicated, and an upper air duct switching device for controlling the on-off switching of the three is further arranged; the lower end of the window frame is also respectively provided with a lower outer air duct communicated to the outer side and a lower inner air duct communicated to the inner side, the lower outer air duct, the lower inner air duct and the lower end of the ventilation inner cavity are communicated, and a lower air duct switching device for controlling the on-off switching of the lower outer air duct, the lower inner air duct and the ventilation inner cavity is arranged among the lower outer air duct, the lower inner air duct and the.

Therefore, the window can control the on-off and switching of the air channels through the upper air channel switching device and the lower air channel switching device so as to meet the air intake and exhaust requirements under different conditions. The air conditioner can be used together with an air supply type fresh air fan or an exhaust type fresh air fan, and the energy consumption of the indoor air conditioner is reduced while the requirement of indoor fresh air volume is met. However, the double-layer glass window simply utilizes the double-layer glass as an air duct, and the effects of indoor heat preservation and energy consumption reduction are still limited, so that further optimization and improvement are needed.

Therefore, the inventor considers to design a technology capable of utilizing the window to perform ventilation switching control, so that the heat transfer effect of the window can be better reduced, the indoor heat insulation performance is improved, and the overall energy consumption of a house temperature control system is reduced.

Is better beneficial to indoor warm keeping so as to reduce indoor heat load.

More specifically, this kind of mode adopts ventilation window to replace traditional door and window to leave the seam and air exhaust, can have following several advantages: 1) the useless hot air which is discharged originally is utilized to heat the glass, and other energy consumption is not increased. 2) The heat of the hot air is retained by enhancing the heat exchange between the air to be exhausted in the room and the glass, and the load in the room is reduced by heating the glass. The purpose of energy conservation is achieved. 3) Through organizing the air through glass intermediate layer passageway, the air is higher than outdoor temperature in the passageway this moment, can block outdoor low temperature and directly transmit to indoor, is equivalent to an air curtain, reduces indoor load, realizes energy-conservation. In this case, the thermal conductivity of our ventilation window is superior to that of the conventional double-layer window. 4) The opening area of the ventilation window is fixed, and compared with window opening ventilation, the problem that the size of the window opening area is not easy to control is solved. 5) Indoor air is discharged outside through the outside ventilation chamber, can be better in the transmission of the solar illumination heat that glass tripe absorbed to indoor and not taken away by the wind current.

In the second application mode, the window, an exhaust fan (namely an exhaust type fresh air fan) and air conditioning equipment are used together in the same building room. Several operation control modes can be realized.

In the summer indoor refrigeration and ventilation mode, (see fig. 12) at the moment, the air conditioning equipment refrigerates, the indoor air temperature is lower than the temperature of the glass window and lower than the outdoor temperature, the exhaust fan is started to exhaust air, and the indoor pressure is lower than the outdoor pressure; at the moment, the louver device is adjusted to enable the glass louver reflection side to face outdoors, meanwhile, the air channel switching of the glass window is controlled to realize air inlet, the air channel is controlled to enable outdoor air to enter the window from the lower outer air channel, one part of air upwards flows out from the upper outer air channel through the outer ventilation cavity, and the other part of air directly enters a room from the lower inner air channel. Therefore, in summer, when solar radiation is strong, the temperature of the window glass is higher than that of outdoor air due to heat accumulation after being irradiated, so that part of inlet air directly enters the room from the lower end of the window, and the condition that the inlet air flows through a ventilation inner cavity and is heated by the glass to improve indoor load is avoided; and another part of the inlet air flows upwards after being heated by the glass in the outer ventilation cavity and is discharged from the upper outer air channel, so that the air flow which flows outwards circularly in the outer ventilation cavity can take away the heat of a part of the glass, and meanwhile, the heat gathered due to the reflection of glass shutters in the outer ventilation cavity can be further taken away by the ascending air flow in the outer ventilation cavity, thereby better achieving the effect of reducing the cold load of the indoor air conditioner.

More specifically, this kind of mode leaves the seam to air exhaust compared with traditional door and window has following advantage: 1) the opening area of the ventilation window is fixed, and compared with window opening ventilation, the problem that the size of the window opening area is not easy to control is solved. 2) The air supply requirement is met, and meanwhile, the external circulation of air in the external ventilation cavity is formed, so that the temperature of the glass and the cavity is reduced, and the load of an indoor air conditioner is reduced; the aim of energy saving is achieved. 3) Through organizing the air and passing through vertical passageway (the ventilation inner chamber promptly), the air temperature is less than glass temperature in the cavity this moment, can block outdoor high temperature and directly transmit to indoor, is equivalent to an air curtain, reduces indoor load, realizes energy-conservation. In this case, the overall heat transfer coefficient of the louver is no worse than that of the conventional sealed double-glazed window. 4) Part of air circulates from outside ventilation chamber and outwards flows and can better take away the heat that gathers in this outside ventilation chamber by the reflection of glass tripe, so can let the window play the indoor outer heat transfer of separation better, to the indoor thermal-insulated effect that falls the load.

2. An indoor heating and ventilation mode in winter (see fig. 13), wherein the air conditioner heats, the indoor air temperature is higher than the outdoor air temperature, the exhaust fan is started to exhaust air, and the indoor pressure is lower than the outdoor pressure; at the moment, the louver device is adjusted to enable the glass louver reflection side to face indoors, the other side of the louver device faces outdoors to absorb solar illumination heat, and meanwhile, the air duct switching of the glass window is controlled to realize air inlet, so that outdoor air enters from the lower outer air duct and flows upwards through the inner ventilation cavity and then enters indoors from the upper inner air duct. Outdoor low temperature air of this in-process passes through the glass intermediate layer and gets into indoorly, preheats in the glass intermediate layer passageway, gets into indoorly again after improving the inlet air temperature, utilizes window glass temperature to preheat admitting air, reaches the purpose that reduces indoor heating load, gets into the air simultaneously and flows from down up through inboard ventilation inner chamber between the glass, can bring into the room along with the wind flow with the absorptive solar illumination heat of glass tripe better when solar illumination. The indoor heating load is better reduced.

More specifically, compared with the traditional door and window seam air inlet mode, the mode has the following advantages: 1) the opening area of ventilation window is fixed, and the problem that the size of windowing area is not good to be held can not exist in the ventilation of windowing, and the ventilation of windowing is because of the area of windowing is not accurate bring the energy waste and can't form effectual air current tissue easily. 2) The entry of slightly heated air into the room may reduce discomfort to the person compared to entry from the window seam: the wind directly seeped from the window seams brings strong cold wind feeling, and is very difficult to feel in winter. 3) Fresh cold air enters the room from above, and the temperature of the air above the room is relatively high. The heat exchange effect after the fresh air enters the room is better, because for this reason, the thermal comfort is also better. 4) The wind flow entering the glass window flows into the room from the inner side ventilation cavity, so that the solar illumination energy irradiated on the glass can be better transmitted into the room as much as possible, and the indoor air conditioning load is better reduced.

In the third application mode, the new fan is not installed in a room, and when the window is directly combined with air conditioning equipment to be used in the same building room, the upper air duct, the lower air duct, the inner air duct and the outer air duct of the window are directly opened to enable the window to naturally ventilate, and the air conditioner is shown in fig. 14-15. Compared with the traditional door and window, the ventilation method has the following advantages that: 1) the opening area of the ventilation window is fixed, and compared with window opening ventilation, the problem that the size of the window opening area is not easy to control is solved. 2) In summer, the outer air duct can be opened again to realize the circulation flow of partial air flow, so that the glass window can be cooled better, and the load of an indoor air conditioner is reduced; the aim of energy conservation is achieved. 3) When the air supply requirement is met, the two air vents are arranged in a high-low mode, so that the air enters and exits at the same time, and the power effect of hot pressing is good. Is beneficial to the circulation of indoor and outdoor air. 4) The condition that still open the window when the resident opens the air conditioner appears seldom when daily use because indoor slight positive pressure like this, the heat runs out the room and causes the waste, reflects in the power consumption increase. But the window is not opened, so that the relevant fresh air volume specification is not met; if open the window, the ventilation efficiency is low because the single face window will regard as the air intake again as the air exit, and the effect is not good, and this problem can effectively be improved to this patent.
