are frequent design average.
5. The indoor air is recirculated and reused in _______________, a smaller amount of air is required, 5
to 10 cu. ft. per person is sufficient.


Sagot :

Answer:

1. Air Conditioning
2. 30 to 35

3. A gentle motion of air produces a refreshing and stimulating effect

4. 76 ̊ to 80 ̊F

5. Air Conditioning

Explanation:

Circulation of Air Conditioning Standards

1. Heating and Humidifying-
A relative humidity of 30 to 35 percent is found most satisfactory in winter.

2. Cooling and Dehumidifying- For summer cooling, temperature of 76 ̊ to 80 ̊F (24.4 ̊C-26.6 ̊C) and 50 percent relative humidity are frequent design average.

3. Air Motion- A gentle motion of air produces a refreshing and stimulating effect. The velocity should average 15 to 25 ft. per minute measured 36 inches above the floor.

4. Air Supply- Many codes require about 30 cu. ft. per min. per person. Since the indoor air is recirculated and reused in air conditioning, a smaller amount of air is required, 5 to 10 cu. ft. per person is sufficient.
