Description

Active heat rejection device for flat roof

This creation belongs to the field of building roof heat rejection technology, especially the design of flat roof heat rejection.

The top floor of high-rise or apartment-style buildings usually adopts a concrete flat roof design. Because sunlight directly shines on the flat roof, the roof absorbs solar heat and transmits it to the room through the roof structure, causing the indoor temperature to rise. In summer, the interior is in a state of extreme heat. In order to reduce the indoor temperature from extreme heat to comfort, the cooling capacity of air-conditioning must be increased by at least 20%. Although inverter air conditioners are available today to save electricity and electricity bills, if they rely too much on air conditioners, they will not only consume energy but also cause environmental concerns.

To improve the heat problem of flat roofs, the conventional technology adopts water-cooling heat insulation technology (such as CN106760264 patent document). Or use air flow ventilation and heat insulation technology (such as CN103080441A patent document). Or use insulation pads (such as the TW170971 patent document), or use insulation materials such as laying hollow bricks and green plants.

The above technical methods are used to reduce the indoor temperature by blocking solar thermal energy through the roof, but the actual effect is not ideal.

In order to solve the above problems, this creation proposes a device that uses thermodynamic airflow to actively remove heat, ventilate, and cool down. This device is installed on a flat roof in block modules.

The technical feature of this creation is an active heat removal device for a flat roof, which includes: an inner slat, an outer slat, a spacer between the inner slat and the outer slat; several peripheral slats The inner shelf board, the outer shelf board and the spacer board are surrounded and fixed to form a modular assembly. In the modular assembly, an air inlet channel and an air inlet are formed between the inner shelf and the partition plate; an exhaust channel and an air outlet are formed between the outer shelf and the partition plate; The exhaust channel and the air inlet channel are connected by a connecting channel; the modular assembly is installed on a flat roof of a building, the outer slab faces the outside to receive sunlight, and the inner slab faces the flat roof; The roof is provided with a heat exhaust port corresponding to the central position of the modular assembly.

The modular assembly is connected to a drainage groove.

The purpose of this creation:

In terms of static conditions, when sunlight directly shines on the outer panel, the temperature of the outer panel and the exhaust channel will be higher than that of the inlet channel and the inner panel. The air barrier effect of the exhaust channel and the air inlet channel creates insulation. The function of heat and insulation reduces the direct transmission of heat to the flat roof.

In terms of dynamics, sunlight directly shines on the outer panel, and the airflow in the exhaust channel and the air inlet channel is caused by the principle of thermal expansion and upward flow of the air. The indoor hot air close to the roof is sucked into the modular assembly and discharged The tuyere released. The indoor hot air is discharged through the modular assembly to achieve the effect of indoor cooling.

The power source of the roof heat rejection device of the present invention is the radiant heat of the sun, and as long as there is sunlight, the above-mentioned effects of natural convection, active heat rejection and indoor temperature reduction can be produced.

The modular assembly can be respectively provided with a drainage groove at the lower end, and rainwater flows into the drainage groove through the inclined outer shelf board and is discharged. The modular assembly shields the flat roof, and in addition to the heat removal function, it can also solve the problem of rain and water leakage on the flat roof.
