Executive Summary 5-12 Applications and monitoring 5 Applications and monitoring The Task 4 Report focused on operating experiences and energy effects of representa- tive industrial heat pump implementations, in particular field tests and case studies. Industrial heat pumps are a class of active heat-recovery equipment that allows the temperature of a waste-heat stream to be increased to a higher, more useful tempera- ture. Consequently, heat pumps can facilitate energy savings when conventional pas- sive-heat recovery is not possible The economics of an installation depends on how the heat pump is applied in the pro- cess. Identification of feasible installation alternatives for the heat pump is therefore of crucial importance. Consideration of fundamental criteria taking into account both heat pump and process characteristics, are useful. The initial procedure should identify a few possible installation alternatives, so the detailed project calculations can concentrate on a limited number of options. The commercially available heat pump types each have different operating characteris- tics and different possible operating temperature ranges. These ranges overlap for some types. Thus, for a particular application, several possible heat pump types often exist. Technical, economic, ecological and practical process criteria determine the best suited type. For all types, the payback period is directly proportional to installation costs, so it is important to investigate possibilities for decreasing these costs for any heat pump installation. The survey with a total of 150 projects and case studies has tried to present good exam- ples of heat-pump technology and its application in industrial processes, field tests and commercial applications along with an analysis of operating data, when available, in accordance with the annex definition of industrial heat pumps, used for heating, ventila- tion, air-conditioning, hot water supply, heating, drying, dehumidification and other purposes.
