ACPH stands for Air Changes Per Hour.
ACPH is a measurement used to determine the rate at which the air in a space is replaced with fresh air.
It is commonly used in HVAC systems to ensure proper ventilation and air quality.
ACPH is calculated by dividing the volume of air in a space by the flow rate of fresh air into that space.
For example, if a room has a volume of 1000 cubic feet and fresh air is supplied at a rate of ...
- Q3. How much ACPH should be maintained in Kitchen?
- Ans.
The recommended ACPH for a kitchen depends on the size and type of kitchen.

Water consumption in cooling tower is calculated based on the cooling load
The thumb rule is 3 GPM per every 100 tons of cooling
Factors like temperature, humidity, and air flow rate affect water consumption
Water treatment and maintenance can also impact water consumption
- Q7. What are the parameters considered while calculating the heat load in a room?
- Ans.
Parameters considered while calculating heat load in a room
Size of the room
Number of occupants
Type and number of electrical appliances
Number and size of windows
Insulation of walls and ceiling
Orientation of the room
Climate of the region
- Q8. Why do we consider the directions while calculating a heat load?
- Ans.
Directions affect the amount of heat transferred and the efficiency of the system.
Heat transfer is affected by the direction of the flow of fluids or gases.
The orientation of the surface being heated or cooled affects the amount of heat transferred.
The direction of the sun's rays can affect the heat load on a building.
The direction of wind flow affects the heat load on a building.
Considering directions helps in designi
