The original intention of the scheme is to provide a ventilation and cooling type equipment room, which is particularly suitable for being applied to high-temperature and rainy environments, as is well known, certain field scientific research stations, meteorological observation stations or industrial agriculture monitoring stations are needed in tropical unmanned islands, tropical and subtropical mountains or deep forests or gobi deserts, and the stations are easily accumulated with high temperature due to the influence of air temperature and internal work heating, so that the work or the service life of the stations is influenced. In a high-temperature environment, an air-conditioning cooling mode is adopted, so that the refrigeration efficiency is very low, and the energy consumption is high; in the environment of power shortage, the active temperature control is difficult to implement, so a ventilation cooling type equipment room is designed.

the ventilation and cooling system can guide air with lower outdoor temperature to the indoor space mainly by utilizing the principle of hot-pressing ventilation and by building air guide measures, and the cold air effectively flows through the surface of an indoor main heat source through the dislocation and opening design of an internal wall body, so that the density of the heated air is lower, a chimney effect is formed, the air naturally rises to the top of an equipment room, and the air is discharged outwards through a top air opening; because the effect of hot-pressing ventilation is mainly determined by the temperature difference between the indoor and the outdoor and the height difference of the air inlet and the air outlet, passive ventilation cooling can be formed even under the windless condition;
hot pressing formula: Δ P ═ gh (ρ O- ρ I)
In the formula: g is a gravity coefficient; h is the height difference of the air inlet and the air outlet; rho O and rho I are density differences of indoor air and outdoor air; Δ P is the pressure difference;
the relation formula of wind speed and wind pressure is as follows:
in the formula, w is wind pressure; v is the wind speed; gamma is the gravity per unit volume of air; g is the acceleration of gravity; under the conditions of the air pressure of 101.325kPa, the normal temperature of 15 ℃ and absolute drying, the air pressure formula under the conditions is as follows:
