The windows of the rented Grade A commercial building are closed and cannot be opened; After washing carpets in summer and autumn, you need to apply for opening fresh air conditioning (ventilation mode) and exhaust air during the holiday season, and set the temperature to the highest; In some poorly ventilated areas, it is suggested to turn on the industrial fan to improve ventilation, so that the wet moisture in the carpet can be quickly discharged outside.
The windows of the rented Grade A commercial building are closed and cannot be opened; After washing the carpet in cold season, you need to apply for opening fresh air conditioning (heating mode) to exhaust air during holidays. The temperature is set to the highest, and some areas are poorly ventilated. It is suggested to turn on the industrial fan, improve ventilation, and let the wet moisture of the carpet be discharged to the outside quickly.
Windows of rented Grade A commercial buildings or self-built offices can be opened; After washing the carpet, open the window and turn on the ventilation mode of fresh air conditioning, which can quickly evaporate the wet water on the carpet and improve the working environment of the office. Why is it a serious mistake to turn on the air conditioner for dehumidification in summer? Please refer to the psychrometric chart of HVAC engineering (I use free Daikin psychrometric chart software). I am not a HVAC major, please correct me. It is a serious mistake to turn on the air conditioner to dehumidify after washing the carpet;
Taking the summer environment of 28 degrees and 75RH%% in Shanghai as an example, the actual water content in the air is17.9g; If the air conditioning temperature is set to 22 degrees for cooling and dehumidification, the humidity in the environment will increase when the office temperature drops to 22 degrees. Suppose the humidity in the office is 96%, the absolute water content in the air is only16g at 22 degrees, and the wet water on the carpet evaporates slowly. At low temperature, condensed water is discharged per unit of air 1. 9 grams, the dehydration effect is not obvious.
Even in the hot and humid summer season, window ventilation can quickly evaporate the moisture in the carpet to the outside; Examples are as follows: The actual water content is17.8g under the environment of 35 degrees and 50RH%% humidity in Shanghai in summer; When the water content is 25 grams at 35 degrees, the humidity is 69.7 RH %；; In this case, when the window is opened, the moisture content of the air in summer is still quite low, from 17.8 g to 25 g, and each unit of air sublimates and evaporates from the wet carpet to 7.2 g of outdoor water, and the humidity only increases by 20Rh%%, which means that the moisture evaporates quickly in summer. Secondly, it strengthens the air flow on the carpet surface and also promotes the moisture sublimation and evaporation of the carpet.
Cooling and dehumidification can be cooled and dehumidified per unit of air1.9g of water; In summer, when windows are opened for ventilation, 7.2 grams of water can be sublimated and evaporated per unit of air, and discharged to the outside.
Therefore, it is a serious mistake to turn on the refrigeration and air conditioning for dehumidification in summer. I have 1. 13MB software of Daikin Air Conditioning, and I want to share it with you!
Even if it doesn't rain in rainy days, the ventilation effect of window opening is good; Anyway, the effect of cooling and dehumidification in summer is not as fast as that of water evaporation and sublimation; The simplest verification method is to put clothes on the balcony to evaporate water quickly, which is much better than turning on the air conditioner in the room to 16 degrees for refrigeration and dehumidification. Many administrative leaders are still insisting on the wrong decision, so consult an air-conditioning professional (I am an amateur) and make progress together!
