The paper presents research on heat transfer coefficient at the surface of sprinkled tube bundle with boil simulation. A tube bundle comprises of thirteen copper tubes divided into two rows and it is located in a low-pressure chamber where vacuum is generated using an exhauster via ejector. The liquid tested was water at absolute pressure in a chamber in between 96.8 kPa up until 12.3 kPa and a thermal gradient 55 to 30 degC between the cooled liquid flowing inside the exchanger upwards and the falling film heated liquid. The flow of the falling film liquid ranged from zero to 17 litres per minute. Two types of tubes have been tested, a smooth one and a sandblasted one. The correlation of average heat transfer coefficient at the surface of both tube types has been created.
