### Define the 1 ton of air-conditioning??

• A.

The amount of heat required to uniform melting of 1 ton of ice within the 24 hours without change in state

• B.

The amount of heat required to uniform melting of 1 ton of ice within the 24 hours without change in pressure

• C.

The amount of heat required to uniform melting of 1 ton of ice within the 24 hours without change in temperature

• D.

The amount of heat required to melting of 1 ton of ice within the 24 hours without change in temperature

• E.

The amount of heat required to uniform melting of 1 ton of ice within the 24 hours without change in volume

C. The amount of heat required to uniform melting of 1 ton of ice within the 24 hours without change in temperature
Explanation
The correct answer is the amount of heat required to uniform melting of 1 ton of ice within the 24 hours without change in temperature. This means that 1 ton of air-conditioning refers to the amount of heat needed to melt 1 ton of ice while keeping the temperature constant. It does not involve any changes in pressure, volume, or state of the ice.

### 1 ton of how much cfm?

• A.

4000

• B.

4500

• C.

### How we calculate 1 air change for room?

• A.

Internal volume/60cfm

• B.

Internal volume/60minute

• C.

Internal volume/120

• D.

60/internal volume

B. Internal volume/60minute
Explanation
The correct answer is "internal volume/60minute." This formula calculates the number of air changes per minute in a room. By dividing the internal volume of the room by 60 minutes, we can determine the rate at which the air in the room needs to be completely replaced. This measurement is commonly used in HVAC systems to ensure proper ventilation and air quality in enclosed spaces.
