1._____ is defined as the simultaneous control of air temperature, humidity, motion and
purity of air in a confined space.
2. A relative humidity of percent is found most satisfactory in winter.
3. A gentle motion of produces a refreshing and stimulating effect.
4. For summer cooling, temperature of _ (24.4 ̊C-26.6 ̊C) and percent relative humidity
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.

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.
