Cooling and dehumidification capacity chart of surface air cooler for air conditioning units

According to the problem of indoor air condition characterized by the traditional psychrometric chart and independent of the abilities of the air conditioning unit in traditional air conditioning design method, gives out the cooling and dehumidification ability chart for different surface air coolers. This chart shares several parameters such as dry-bulb temperature, moisture, relative humidity and specific enthalpy of air, as well as sensible and latent heat load handling capacity. On the capacity chart of surface air cooler we can illustrate the sensible and latent heat loads, trace the transient air conditioning processes, and find the equilibrium state of indoor air condition given by a surface cooler in different indoor sensible and latent heat loads.
