What are the factors that affect the change of indoor temperature and humidity?

(1) In China's hot summer and cold winter areas, due to its unique geographical location, the summer temperature is high, the number of days above 35℃ is 15-25, and the temperature on the hottest day can reach 4 1℃, giving people a sultry feeling. Annual humidity is a remarkable feature of the climate in this area, with an average annual relative humidity of about 70%-80% and sometimes as high as 95%- 100%.

(2) People's access frequency, number of doors and windows, indoor temperature, airflow speed, indoor water source, house orientation, and moisture absorption capacity of indoor articles (classification; For example, hardwood furniture and Chinese fir furniture, painted furniture and unpainted furniture have different water absorption capacity); (3) Indoor space size, clean space, effective space = clean space/indoor space, wall structure (brick wall and putty are different when painting latex paint), floor structure, air conditioning equipment, and so on;

(4) In recent years, the health problems caused by indoor environmental pollution have become increasingly prominent. People spend more than 80% of their time indoors, and the carbon dioxide exhaled by people is also one of the reasons;

(5) The transpiration of plants releases water into the air, and leaves can absorb water, so how can there be more water in general?

(6) After air conditioning refrigeration, the indoor temperature gradually decreased, but the relative humidity of indoor air also decreased obviously. The higher the temperature, the stronger the capacity of saturated water vapor that can be contained in the air. When the temperature drops during refrigeration, the relative humidity should increase. Only in this case is it right: when cooling, the indoor air is relatively closed, and once the moisture in the air is fixed, the relative humidity in the room will increase. However, during refrigeration, the indoor unit sucks hot air like a cold heat exchanger, and the moisture in the air will be suspected to form water and be discharged outside. In fact, it is also the process of air dehumidification, and the moisture in the air will be lost (air conditioning needs tap water, and this water is the moisture in your room air). When the natural temperature is low and the air is dry, the relative humidity will decrease.
