The average commercial A/C size ranges from 2 tons for small buildings to as much as 30 tons for very large buildings. A 1-ton air conditioner can remove around 12,000 Btu, or British Thermal Units, of heat per hour. To know what size air conditioner your building requires, you'll need to calculate the building's cooling load in Btu. The ...

Bench Grinder Exhaust Ventilation • However there are losses thru the grinder hood entry SP 2 = - (VP 2 + h e) where h e is the energy loss of the hood entry • Static pressure (SP) must decrease due to acceleration of air up to the duct velocity • F h is defined as the energy loss factor (for that hood design) • Energy losses will be measured as a function of the velocity pressure in ...

Practice these calculations several times in the shop or office. Then do the calculations in the field several times over the next week to check airflow in rooms with uncommon ventilation requirements. Study the Air Changes per Hour Table to become familiar with the rooms that need more ventilation than the heating or cooling load requires.

Aug 09, 2007· I have been asked to do a load calculation for a 8,000 SQFT industrial building. The building is being used for plating. Since this is my first industrial load calc, i though i ask you guys who have more experience in industrial that may be able to help me.

This method takes in account the calculation for: thermal exchange for transmission and ventilation of the building zone when it is warmed or cooled at a constant set point tem-perature, the contribution of internal and solar thermal gain and, as a consequence, the annual energy need for heating and cooling of thermal zones.

Jul 03, 2018· So if we drop those values in for room 1 we get a volume flow rate of 0.2158m3/s that is how much air needs to enter the room to meet the cooling load. So just repeat that calculation for all the rooms. Building air volume flow rates – duct sizing. Now we're going to sketch out our ductwork route onto the floor plan so we can start to size it.
