MCQ PSYCHROMETRIC CHART

MCQ increases the depth of understanding

and clarity. It clarifies the heating and

humidification, cooling and

dehumidification processes. All other

psychrometric processes on chart is made

understood. All this information is helpful

in the designing of air conditioning

equipment.
