Heating, ventilation and air conditioning (HVAC) calculations

Performing calculations in the development of heating, ventilation and air conditioning systems

List of calculations performed in the development of heating, ventilation and air conditioning systems:

• Calculation of heat transfer resistance, heat absorption , vapor permeability, thermal resistance of building structures
• Calculation of heat losses
• Calculation of the dew point
• Calculation of heat gains
• Calculation of losses during transportation of an energy carrier
