2. Methods of product selection
Enthalpy difference correction
Make corrections based m-the ratio between the enthalpy difference during actual operation
and that at standard condition, and calculate the actual cooling capacity of the fan coil, then
select the correct fan coil based on actual cooling capacity.

Airflow based type selection
Select a fan coil based on the air conditioning flow calculated by the cooling load of air
conditioning and the actual air treatment enthalpy difference of the fan coil.

Besides, when the water supply temperature, temperature difference of supply and return
water, water supply and inlet air temperature are different than those of the standard
condition, further correction is required based on the information.
