Full Description

Brazed plate heat exchangers (BPHEs) have been recently introduced in the air conditioning industry because they could provide higher heat transfer rate per unit volume and are more compact than conventional tube-and-shell exchangers. This report presents a new experimental methodology and results of waterside thermal performance of brazed-type condensers under fouling operating conditions. High and medium water fouling potentials were developed in laboratory to create conditions that cause severe and medium precipitation and particulate fouling during the experiments. Corrosion and biological fouling were intentionally prevented by chemical inhibitors. Among other advantages, the new methodology is independent from the geographical location of the laboratory and from the local water supply source. Using this technique a Langelier Saturation Index of the water of about 3 - 3.5 was achieved, which represents very severe fouling conditions.
