AHU PSYCHROMETRIC CALCULATOR is designed for engineers involved in air conditioning design. If the temperature on a cooling surface - tC - is above or equal to the dew point temperature - tDP - of the surrounding air, the air will be cooled without any change in specific humidity. As you can see, in the case of a hot water coil, where the air is heated and the water is cooled, the above equation will result in a negative Q. In this video we take a look at the cooling coil for HVAC systems typical in Air handling units and Fan coil units to help you learn HVAC online. The air cools along a constant specific humidity - x - line as indicated in the Mollier diagram below: The process is very similar (opposite direction) to the sensible heating process and the heating formulas can be adapted to calculate change in enthalpy and temperature. Unit  Conversions -  HVAC, Water Mix Wizard - Systems, Steam & desired mix temperature, Flash & Flash Reserved, Chilled Water Calculated Cooling Load: Find Matching Products * This calculator is meant to be used only as a general guide. 1 combines all the factors that determine the surface area of the heat transfer device.A = Q/UT. - Load, Flow & β = ((70 kJ/kg) - (38.5 kJ/kg)) / ((70 kJ/kg) - (8.5 kJ/kg)), q = (1 m3/s) (1.205 kg/m3) ((70 kJ/kg) - (38.5 kJ/kg)), The sensible heat flow can be calculated as, qs = (1 m3/s) (1.205 kg/m3) (1.01 kJ/kg.oC) (30oC - 15oC), According the Mollier diagram the specific humidity in (A) is 0.016 kg/kg and in (B) 0.0096 kg/kg and the latent heat flow can be calculated as, qs = (1 m3/s) (1.205 kg/m3) (2502 kJ/kg) ((0.016 kg/kg) - (0.0096 kg/kg)). When cooling air - part of the energy is used to separate the water (latent heat), and the rest is used to lower the air temperature (sensible heat). BTUH (t) = Total BTU per Hour Et (h) = Entering Total Heat (BTU/LB of Dry Air) The Specific heat capacity (Cp) … Estimation, Refrigeration If you use this equation then you will get the following: Qt = 4.5 * 15000 * (41.25 – 24.62) = 1,122,525 Btu/hr, or a perceived error of 8.3.
