Air quality-inducing intelligent constant temperature ecological curtain wall system and temperature control method

Abstract

The invention relates to an air quality-inducing intelligent constant temperature ecological curtain wall system and a temperature control method, belongs to the field of curtain walls and solves the problem that an air conditioning system is high in energy consumption. The system is combined with a constant temperature curtain wall by virtue of a computer system, so that the system has multiple working modes; the working modes are intelligently selected and switched according to the indoor and outdoor temperatures, the temperature of a hollow interlayer and an outdoor air quality, and intelligent temperature control is realized, so that the energy consumption of the air conditioning system in heating and refrigerating processes is reduced, and the system has a good energy-saving effect and an ability of coping with environmental changes.

Description

technical field [0001] The invention relates to the field of curtain walls, in particular to an air quality sensing intelligent constant temperature ecological curtain wall system and a temperature control method. Background technique [0002] The curtain wall is the "outerwear" of the building. Most modern buildings are decorated with curtain walls. Among them, large shopping malls, office buildings and other buildings have high requirements for the comfort of their internal environment. Generally, they are equipped with air conditioning systems for cooling or heating to keep the interior Constant temperature, but this also brings a huge problem of air conditioning energy consumption. As the intermediate of indoor and outdoor heat exchange, the curtain wall plays an important role in maintaining the constant temperature environment in the building. [0003] Following the above trend, the constant temperature curtain wall has gradually entered people's field of vision. Figu...

[0004] However, the constant temperature and energy saving performance of this constant temperature curtain wall is not significant, mainly due to its passivity. Even if the above-mentioned air inlets and exhaust outlets of the constant temperature curtain wall are opened for ventilation, according to the chimney effect, although the airflow circulating in the middle compartment can take away part of the heat, the airflow is still a hot air flow with a relatively high temperature, and it is difficult to make the middle compartment The temperature in the layer is greatly reduced, so the temperature difference between the two sides of the inner glass is relatively large. According to the calculation formula of heat transfer rate: q=-λA(dt/dx), λ is the thermal conductivity, A is the heat transfer area, t is the temperature, x is the coordinate on the heat conduction surface, q is the heat flux density transferred along the x direction, dt/dx is the temperature change rate of the object along the x direction, - means that the heat transfer direction is opposite to the temperature change rate direction, it can be seen , the rate of heat transfer is proportional to the temperature difference. At this time, the amount of heat exchange between indoors and outdoors is large, and the problem of energy consumption of air conditioners is still significant. It is difficult to achieve better energy-saving effects by passively relying on natural thermal effects for heat exchange.

[0005] The invention patent with the publication number CN104453039A discloses a composite temperature-controlled curtain wall with a three-layer glass structure. The overall active heat exchange realizes the function of
