This paper presents current research of our team in sprinkled heat exchangers. This type of research has become rather topical in relation to sea water desalination. This process uses sprinkling of exchangers, which rapidly separates vapour phase from a liquid phase. Applications help better utilize low-potential heat which is commonly wasted in utility systems. Low-potential heat may increase utilization of primary materials. Sprinkled tube bundles are not a new technology; however, they have been researched and designed in experiments when commonly only one heated tube was scrutinized under laboratory conditions. Our ambition is to analyse and describe reactions of the whole sprinkled exchanger. We tested an exchanger comprising four tubes, and observed progress of boiling on the bundle for two various flow rates (ca. 0.07 and 0.11 kg/(s.m). Initial pressure was ca. 10 kPa (abs) at which no liquid was boiling at any part of the exchanger; the pressure was then lowered. Other input parameters were roughly similar for both flow rates. Temperature of heating water was ca. 50 °C at a constant flow rate of ca. 7.2 L per minute. Results of our experiments provide optimum parameters for the given conditions.
