Design and calculation of outdoor air dehumidification in radiant air conditioning system

According to the radiant air conditioning system of a residential building in Beijing, calculates the humidity ratio of outdoor supply air in this system, and draws the enthalpy-humidity chart. Determines the dehumidification state points of internal cooling double cold source heat recovery outdoor air handling unit by the enthalpy-humidity chart, summarizes the matters needing attention in design and calculation, and proposes a method to improve the energy efficiency ratio further.
