What size of supplementary air conditioning system do I need for my specific fit-out project? 

To ascertain the accurate size of a supplementary air conditioning unit for your fit-out project, a meticulous examination of various parameters is essential. Here's an orderly procedure to aid you in defining the right size utilising the Supplementary AC calculator, designed by our seasoned professionals:

Step 1 - Enter the number of occupants for the designated space

Step 2 - Enter the total area of the space in square meters

Steps 3 & 4 - Insert the Base Building (B/B) occupancy rate and B/B outdoor air allowance - for most buildings, the figure 10 may be applied to both fields

Step 5 - Here you have the option to overwrite the count of occupants beyond the B/B allowance if this data is available

Step 6 - Input the geographical location of the project - This information assists in defining the outdoor parameters necessary for load assessment

Step 7 - Enter the targeted indoor temperature

Step 8 - Insert a safety margin - it is advisable to maintain this field at zero if detailed project specifications are known, to prevent unnecessary enlargement of the needed air conditioning equipment

Step 9 - Record the intensity of human activity - This variable influences the quantities of both sensible and latent heat per individual

Steps 10 & 11 - Here you can register the electrical consumption per person or any supplementary electrical usage as sensible heat load, measured in Watts

Step 12 - Here the quantity of AC units can be determined. Note: if the computed thermal demand exceeds the maximum capacity of the largest available AC unit, multiple AC units may be utilised to satisfy the thermal load

True Partners' Supplementary AC calculator will suggest the most compact water-cooled packaged units capable of countering the additional thermal requirement. Within the filtration requirement segment, the needed efficiency grade for the supplementary air conditioning unit's filter to meet the allowable reduced outside air rate in accordance with AS1668.2 is displayed. Reduced outside air rates, will result in requirement for smaller supplementary air conditioning units. 

Incorporating extra outdoor air for a fit-out project can present obstacles in certain structures if no preliminary arrangements have been instituted.
