Match properties of heat exchange network in thermal-hygro environment building

Researches the heat exchange network of active air conditioning system, and analyses the influence of match properties in sensible heat transfer and heat and moisture transfer processes. Limited heat transfer capability and unmatched flow rate at both sides result in loss of sensible heat transfer capacity. The loss of heat and moisture transfer process arises from limited heat and mass transfer capability, unmatched flow rate and unmatched parameters. The condition for flow matching is equal thermal capacity of fluids in both sides and parameter matching can only be reached in air-water heat and moisture transfer process along the saturation line. Obtains the expressions of heat transfer resistance and moisture transfer resistance through analytic method. Analyses the influences of limited heat and mass transfer capability, unmatched flow rate and unmatched parameters on heat transfer resistance and moisture transfer resistance.
