Hi guys i have one question why when i make a increasing on coil temp. for example from ( 80/67F dbt/wbt) to 89/69 dbt/wbt
capacity it will increased?

I hope somebody will help me as soon as possible

Carrier performance tables suggest about 900btu/1000 cfm/(T-80). So at 89 deg entering water temperature, the sensible capacity would increase 8100 btuh for each 1000 cfm of evaporator air flow. Latent capacity is not affected.

Best bet is to contact the manufacturer's rep if you want a more exact answer.

This manufacturer does a free software for coil selection / engineering queries etc. I haven't used the current version but the older versions used to be quite good for working out performance for new or existing coils.

thanks guys


I means when i make increase on on coil Temp capacity will increase also
