Double-layer curtain walls rose in European countries in the last century, but the cost of double-layer curtain walls is too high, and now the double-layer curtain walls put into practical projects The curtain wall is generally a single internal circulation or external circulation, lacking the structural measures of two-way circulation. The external circulation in summer is to let the outdoor air rise into the glass cavity through the chimney effect and take away the heat of the louvers in the glass cavity to reduce the indoor temperature. To achieve the good effect of external shading, the hot air in the cavity can be discharged from the holes in the external wall, or it can be discharged from the additional heat channel installed on the side by using the chimney effect. In winter, when the ventilation grid is closed, a greenhouse effect is formed in the cavity, which prevents the indoor heat from dissipating to the external environment. The glass cavity forms double-layer glass plus an internal air layer to increase the effect of thermal resistance. The internal circulation is to take away the heat in the louvers through the mechanical ventilation device and cool the outdoor hot air sent into the room through the heat mass exchanger to achieve the balance of the indoor temperature, but in general, the internal circulation requires mechanical ventilation and heat mass exchangers Participate in work, and take away the heat on the louvers from the indoor air, which will take away the original part of the indoor cold air, so the energy consumption is higher than the external circulation, and the cooling effect is limited.

Considering the comfortable range of human body temperature, it is assumed that the temperature of the three spaces, outdoor, cavity, and indoor, from low to high, is outdoor , indoor, inside the glass cavity. Although the cavity formed by the pure greenhouse effect can prevent heat dissipation from the room to the outside, due to the temperature difference between the three spaces, the heat loss from the cavity to the outside will be greater than the heat from the cavity to the room. After irradiating the louvers on the black surface, the air temperature is higher than the indoor effect. The upper and lower sides of the inner glass are dug, and the chimney effect is used to circulate and circulate with the indoor air to form a device similar to the principle of a solar thermal storage wall and indoor air circulation to provide indoor heat, reducing the original The temperature difference between the closed cavity and the indoor and outdoor keeps the temperature in the cavity within a range close to the indoor temperature. At the same time, the decrease in the temperature in the cavity reduces the temperature difference with the outdoor and reduces the heat lost to the outdoor. And the heat lost to the outside as a whole with the indoor. Make full use of the heat formed by the cavity to reduce the heat load of the air conditioner for indoor heating. According to the known indoor human body comfortable temperature in winter and the average outdoor temperature in winter in different regions, in order to ensure that the temperature in the cavity similar to the principle of the glass greenhouse is equal to or higher than the indoor temperature, the glass on the glass cavity configured by the utility model needs to be as large as possible. Thermal resistance; designed as a hidden frame glass curtain wall structure, and coated with a heat-absorbing material with excellent performance on the rotating louvers to store more heat in the cavity and minimize heat dissipation to the outside to achieve a high temperature inside the glass cavity Based on the effect of a certain temperature in the room, it achieves the function of supplying heat to the room through internal circulation. The utility model aims at the advantage of two-way circulation, through a series of mechanical transmission devices, through the simple operation steps of manpower pushing and pulling the handle to change the direction of air circulation and the rotation of the louvers to reflect and absorb heat, so as to achieve the effect of reducing the load of indoor air conditioning. Poor ventilation with the outdoor air caused by simple internal circulation in winter is also a problem that cannot be ignored. Through the original supporting mechanical fresh air replacement device, or the installation of connecting rods on the double-layer glass to form a double-body casement window (glass opening on one side of the room) It is also a way to solve the replacement of fresh air in winter.
