根据《民规》第7.3.19第二条，空调区的新风量，应按不小于新风除湿所

According to Article 7.3.19, Article 2 of the Civil Code, the fresh air volume in the air-conditioning area should be not less than the fresh air volume required for dehumidification of the fresh air, the sum of the fresh air volume required to maintain the air pressure in the air-conditioning area and the compensation for the exhaust air and the new air volume required by the personnel The maximum value of the air volume is determined; the room's moisture dissipation is very small, and the dehumidification is borne by the fan coil, so the new air volume is the larger of the sum of the new air volume required to maintain the air pressure of the air-conditioning area and the compensation exhaust air, and the fresh air volume required by the personnel Select. <br>According to Article 3.0.6 of the Civil Code, it is determined that the fresh air volume of the office and lounge is 30m / h per person, and the lobby and the Four Seasons Hall are 10m / h per person. According to Article 8.3 on page 19 of the Design Manual, the number of ventilations is maintained at a positive indoor pressure of 10 Pa. The required number of ventilations is 1.2 times / h, and the required number of ventilations in the bathroom is 3 times / h.

According to Article 7.3.19 of the Civil Regulations, the new air volume of the air-conditioning area shall be determined according to the new air volume required to remove the new air and the new air volume required to maintain the air pressure of the air conditioning area and the maximum amount of the new air volume required for the personnel and the new air volume required by the personnel;<br>In accordance with article 3.0.6 of the Civil Code, the new wind volume in the office and lounge is determined to be 30 m/h per person, and the lobby and four-season hall will be 10 m/h per person. In accordance with the 8.3 ventilation frequency method on page 19 of the Design Manual, the indoor positive pressure of 10Pa is maintained, the number of ventilation required is 1.2 times/h, and the number of ventilation required in the toilet is 3 times/h.

According to Article 2 of article 7.3.19 of the civil code, the fresh air volume of the air conditioning area shall be determined according to the sum of the fresh air volume required by the fresh air dehumidification, the fresh air volume required to maintain the air pressure of the air conditioning area, the compensation exhaust air volume and the maximum fresh air volume required by the personnel; The room has a small amount of dehumidification, and the dehumidification is carried out by the fan coil. Therefore, the new air volume is selected according to the larger value of the sum of the fresh air volume required to maintain the air pressure in the air conditioning area, the compensation exhaust air volume and the fresh air volume required by the personnel.<br>According to Article - of 3.0.6 of the civil code, the fresh air volume of the office and the rest room is determined to be 30m / h for each person, and that of the lobby and the four seasons hall is determined to be 10m / h for each person. According to Article 8.3 of page 19 of the design manual, maintain the indoor positive pressure of 10Pa, the required air change times are 1.2 times / h, and the required air change times for the toilet are 3 times / h.
