FAQ

A sensible heat exchanger transfers temperature only, using hydrophilic aluminium foil of 0.1–0.2 mm thickness. A total heat exchanger also transfers moisture, using heat exchange paper made of specialty fibres with gaps so small that only small-diameter water vapour molecules can pass through — larger harmful gases and odour molecules cannot. Total heat exchangers cost more per square metre but reduce the latent load that the air-conditioning system has to remove.
