SENSIBLE HEAT FACTOR or RATIO (SHR)

SENSIBLE HEAT FACTOR or RATIO (SHR)

SHR = Hs / Ht = Hs / (Hs + HL ) 

Where

• SHR = Sensible heat ratio

• HS = Sensible heat gain

• HL = Latent heat gain

• Ht = Total heat gain

Notes:

1. SHR from 0.95 - 1.00 for Precision air conditioning (computers and data centres)

2. SHR from 0.65 - 0.75 for Comfort cooling (people)

3. SHR from 0.50 - 0.60 for Dehumidification (pools and outside air)

Lower SHR value indicates that the dehumidification requirement will be high and the supply air leaving the cooling coil shall be at lower temperature to meet the dehumidification needs. The supply airflow rate will be less. (See below for further justification)
