NAME : MOHD SYAMSYURI BIN ZAKARIA
ID NUMBER : 2012837694
COMPANY NAME : SAI COND SALES AND
ENGINEERING SDN. BHD

2. COMPANY’S PRODUCT
 Air Handling Unit (AHU) – used to regulate and circulate air as part
of a heating, ventilating, and air-conditioning system.
 Polyurethane Panel – as an insulation to control cold-room function
 Fan-coil units – to control the temperature
 Insulated door
Future
 Truck Refrigerator Unit

3. CONDENSATION RISK
ANALYSIS
Problem Statement
At the various temperature and thickness of the panel can
occur condensation or not?
Objective
To determine the effect of the thickness of the wall and
temperature inner and outer of polyurethane panel on the
condensation at the outer wall of panel.

4. Sample Calculation

6. Result

8. Conclusion
In conclusion, the condensation is not occur at the outer wall
panel in various thickness and various of inner and outer
temperature of panel

12. Analysis
Yield strength of steel = 2.75x10^8 Pa
Max VMS = 2.77x10^4 Pa
VMS < Yield stress
So that, the design is safe
