Many office buildings in Chengdu, Sichuan are limited by high temperature. How can an office building without air conditioning work normally?

Many office buildings in Chengdu, Sichuan were cut off due to high temperature, and the central air conditioning of the buildings stopped cooling. The property service center closed all the backstage billing systems, and no air-conditioning transportation fee was charged during the closing of the energy station. The owner is also required to close the indoor air conditioning panel to avoid unnecessary losses caused by the recovery of refrigeration billing. The unusually strong subtropical high has brought severe convective weather and extreme high temperature to Sichuan Basin this year, with the average rainfall halved and the power demand sharply increased.

The largest hydropower province? It puts forward a great test for the company's power supply guarantee ability. In July, State Grid Sichuan Electric Power sold 29.087 billion kWh of electricity, up by 19.79% year-on-year, setting a record for monthly electricity sales. Recently, Sichuan province announced that the power supply guarantee has entered the most severe and extreme moment, and industrial power consumption enterprises have stopped working for six days. Put a few more pots of clean water in the room and blow it with a fan, which can reach the cooling range of 1-3 degrees. Sprinkle a proper amount of water on the floor of the room and blow it with a fan to achieve a refrigeration range of 2-5 degrees. Put the ice cubes in the room in a container to cool down, and at the same time turn on the fan to cool down, about 3 to 7 degrees; Using air-conditioning fan, the temperature is about 2 to 6 degrees, and if using ice crystal box, it can achieve refrigeration of about 3 to 8 degrees.

According to the common sense of physics, the evaporation of water will absorb a lot of heat, and turning on the fan can accelerate the evaporation of water; Melting ice into water can absorb a lot of heat. When using these methods to cool down, be sure to open doors and windows regularly for ventilation to avoid the increase of indoor air humidity. The working principle of environmental protection air conditioner is to use water curtain as cooling medium. Water flows evenly from the top of the water curtain along the corrugated surface of the water curtain, so that the water curtain is evenly moist from top to bottom. When the air flows over the surface of porous wet water curtain, a lot of damp heat in the air is converted into latent heat, which forces the air entering the room to drop from dry bulb temperature to wet bulb temperature, thus increasing the humidity of the air, turning dry hot air into clean and cool air, thus playing the role of cooling and humidifying. The core component of refrigeration is the water curtain evaporator.
