Abstract A cooling and dehumidification coil is an essential component of both conventional and no conventional air-condition systems Therefore the objective of this thesis is to present a comprehensive heat and mass transfer performance analysis or a cooling and dehumidification coil at different operating conditions. for this purpose, a set of coupled differential equations describing the heat and mass transfer from a water-cooled coil are solved numerically. Several controlling parameters are identified to analyze the part-load performance of a coil that is my be operated under dry, partially wet, and completely wet modes, Air side enthalpy and humidity effectiveness are defined and used to report the part load performance. finally, the pairt-load performance as predicted by the numerical model is compared with an easy-to-use procedure and with the catalog data for commercially available cooling coils. |
