Selection procedureDetermining the totalcapacityUse the cooling and heatingcapacity tables and the air flowdata to choose the unitcorresponding to your needs.Apply the following capacitycorrection factors, according to:- the temperature difference incooling mode, if it is not 5°C,- the air flow, if it is not thenominal air flow,- the % of ethylene-glycolcontained in the water circuit.Calculate the water flowaccording to the correctedcapacity data:Q =Corr. Capacity x 0.239temp. diff• The water pressure losses in theexchange coils and control valvesmust be determined using thegraphs on page 8.• The available static pressurevalues for the duct network at theFWD unit discharge are given bythe table on page 10.• The air pressure losses indicatedfor the different accessories are tobe taken into account todetermine the system's aerauliccharacteristics.Determining the sensiblecapacity• Use the TRANE pyschometricgraph on page 43 directly todetermine:1. The enthalpy of the air enteringthe HE coil (in kJ/kg of dry air) forthe relevant DB temperature anddegree of moisture.2. The specific volume V (in m 3 /kg ofdry air).3. The moisture content MC (in kg/kgof dry air).• Calculate the air mass M (in kg/s)entering the coilM = Q x (1 + MC)Vwhere Q = air flow in m 3 /s• Calculate the enthalpy of the airleaving HLHL = HE - PFMwhere PF = total cooling capacity.• On the graph, plot the enthalphyline HL, and then from the pointcorresponding to the DB/WBentering temperature on the coil,plot the line parallel to thestandard coil curves. Itsintersection with the enthalpy linedefines the DB/WB leavingtemperatures.• Calculate the difference betweenthe DB entering and leavingtemperatures: +ta (in °C)• Calculate the sensible capacity PsPs = +ta x 1.214 x QUNT-PRC002-GB5
