Objective The aim of the project is to demonstrate that a heat pump, driven by a gas engine can be successfully used, from both a technical and economic viewpoint, to raise low pressure steam for process use.The plant was installed at IRD. After commissioning in January 1983 2000 hours of trials were carried out to prove the reliability and long term performance at operating conditions similar to those in the industrial process. The plant reached a maximum output of 325 kW and with a fuel input of 216 kW. The primary energy ratio is 1,51. A payback period of 3.6 to 4.9 years was estimated.NET-IRD is interested in joint ventures in the heat pump area.The heat pump is designed to produce low pressure saturated steam (about 600 kg/h at 110 deg C) in the condenser using an engine and exhaust heat recovery system. Originally the system should be installed in a chemical plant where exhaust gases from a chemical reaction could be used as heat source. The system is designed for an evaporator inlet temperature of the waste water of 80 deg.C. The used working fluid R 114 is evaporating at 60 deg.C. and condensing at 120 deg.C. The gas engine with a continuous power output of 75 kw uses ebullient cooling (two phase, liquid vapour flash).The system is based on a R & D project subsidised by DG XII. The demonstration plant is essentially a modification of the prototype.
