Question 5.
In a HVAC system design, if the outside temperature is 35°C and the desired indoor DPT is 20°C, what would be the considerations for cooling the air?
Show hintHide hint
Consider the interaction of cooling and dehumidification.
Question 6.
An industrial application requires a maximum DPT of 15°C to avoid mold growth. Given the air temperature is 25°C and RH is measured at 70%, should the system initiate dehumidification?
Show hintHide hint
Use the formula to confirm DPT is above the threshold.
