is the same as Example1-1.

(2) Air condition difference factor
Characteristics for heating written in specification sheet are based on air conditions of outdoor air: 7°CDB, 6°CWB and
return air: 20°CDB, 15°CWB.

(G) Heating capacity under specification condition
- Lossnay recovery
- Heating capacity of Dx-coil unit

II: Calculate Dx-coil inlet air (Lossnay outlet air) condition

The conditions of Lossnay outlet air are already calculated in STEP1-III

as shown below.
