Description
Technical Field
The invention relates to a large and tall bungalow house and a forced circulation roof ventilation method.
Background
In high-temperature seasons, the heat transfer quantity of the roof of the grain flat warehouse is more than 10 times of that of the wall, and the heat transfer quantity is the main reason for accumulating heat of grains in the warehouse. The heat insulation of the warehouse roof part is enhanced, and the heat insulation plays a vital role in reducing the temperature and energy consumption of the stored grains in the flat warehouse. Because of the requirements of grain warehouse such as water resistance, insect prevention, sealing, bearing and the like, energy-saving measures such as public building water storage roofs, roof greening and the like are difficult to popularize and apply in the heat insulation reconstruction of the active single-storey house enclosure structure, and the existing warehouse roof heat insulation measures comprise reinforcing heat preservation, setting natural ventilation of roofs, adopting reflective coating, adopting overhead layer heat insulation and the like. Taking into account the life of the material and the heat transfer characteristics of the warehouse roof, it is a more advantageous way to insulate the overhead layer.
With respect to the overhead layer heat insulation technology, civil buildings, particularly single residential buildings, commonly adopt an overhead layer with the height of 15-20 cm, air in the overhead layer flows from cornice to ridge direction along the roof gradient under the action of hot pressing, so that the heat of solar radiation is prevented from being absorbed and stored by roof entities, and the aim of preventing indoor temperature from rising is achieved. In the old warehouse reconstruction engineering, the method is used for the heat insulation reconstruction of an overhead layer, but because the grain warehouse and civil buildings have different purposes, the grain warehouse and the civil buildings have obvious differences in the geometric proportion of building structures, scales and different functional parts (including depth, span, roof, beam column and the like). For example, the grain warehouse roof span is larger, but the thickness of the overhead layer in civil buildings is usually not more than 20cm, when the thickness is directly applied to the high and large grain warehouse buildings, the overhead layer actually presents long and narrow and/or flat geometric characteristics, so that effective air flow is difficult to form, the heat insulation effect is poor, the natural cooling speed in the grain warehouse is small, the grain storage quality is influenced, and the energy consumption of the manual cooling device is additionally increased.

EXAMPLE 3 Ventilation method
The forced circulation roof ventilation method of the tall bungalow is described in detail below. Specifically, based on the tall flat warehouse of example 1 or example 2, all fans 23 are controlled to operate normally when the outdoor wind speed is <5 m/s. The fan 23 can generate induced air flow at the air outlet 202 of the overhead floor 203, and the induced air flow flows through the overhead floor 203 in a forced circulation convection mode to cool and insulate the roof 11. When the outdoor wind speed is more than or equal to 5m/s, all fans 23 are controlled to stop running.
