Answers & Comments
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.
