The total ventilation air that should be supplied to the dining space in order to achieve acceptable indoor air quantity is________

To answer this question, we need more specific information such as the size of the dining space, the number of people it accommodates, and the specific ventilation standards or guidelines you are following.

However, as a general guideline, the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) recommends a ventilation rate of 7.5 cfm (cubic feet per minute) per person plus 0.06 cfm per square foot for dining spaces.

Here are the steps to calculate the total ventilation air:

1. Determine the number of people the dining space can accommodate.
2. Multiply this number by 7.5 to get the total cfm required for the people.
3. Calculate the area of the dining space in square feet.
4. Multiply the area by 0.06 to get the total cfm required for the space.
5. Add the cfm required for the people and the space to get the total ventilation air required.

Please note that these are general guidelines and the specific requirements can vary based on local regulations and specific conditions of the space.
