HVAC كورس تصميم نظام التكييف

o HVAC

- Read and understand architectural Drawing

- Project data collection ( orientation – elevation – walls exposure – floor area – no. of people – lighting load – electrical equipment's load – widows )

- Load Estimation by ( Quick sizing (ASHRAE) - HAP software – Revit )

- Make a report Include ( total coil load – sensible coil load – cfm – entering db/wb temp – outdoor ventilation )

- Use HAP report to make unit selection{ DX system (Decorative , Concealed , Packaged) – Chilled water system ( air cold chiller – water cold chiller) }

- selection for (FCU – AHU) Depending on Cooling Capacity , CFM , gpm

- selection for Cooling tower

- selection for PUMP Depending on gpm , Pressure Drop

- selection for HOOKUP of all systems .

- Air outlet selection ( square – round – linear bar – linear slot – jet diffuser ) Depending on

- ( total air flow rate – no. of supply – no. of return – position – NC – air throw – pressure drop )

- Duct systems design (rectangular – round) By Mcquay Duct Sizer Depending on (air flow rat – duct fitting – accessories )

- External Static presser calculation

- Design Drawings ( Autocad – Revit)

- BOQ & Specifications
