Selecting the right industrial heat pump needs both, realistic operating scenarios and detailed performance data.
Industrial heat pumps are in high demand in all industries to meet decarbonization targets or simply to increase overall process efficiency by upgrading ambient or waste heat. Compared to the traditional way of burning fuel in a stand-alone heater, heat pumps can produce the same output with a fraction of the primary energy input by tapping into ambient or waste heat sources that are available for free. Depending on the temperature difference between the heat source and the required supply, heat pumps can multiply the energy input from the electrical driver by a factor of five and above.
Understanding the operating behaviour outside the design point is key to evaluating industrial heat pumps. In the ENEXSA Heat Pump Library for EBSILON®
Professional, industrial
heat pumps are modelled through multi-dimensional interpolation of the manufacturer’s performance curves. For a specific application (heating,
cooling or combined heating & cooling) and specific combination of media (water, brine, air), the parameters of the
heat pump model include: ● Cold side inlet temperature, ● cold side temperature drop, ● hot side outlet temperature, ● hot side temperature lift, and ● part load fraction.
The results comprise of the heating/ cooling capacity, the compressor and other auxiliary power consumption, and the key figures Coefficient of Performance (COP) and Energy Efficiency Ratio (EER), respectively. In addition, the technical constraints in terms of inlet and outlet temperature limits as well as applicable flow limits are part of the data sets.
How to find the right heat pump system?
Finding the optimal solution is a quite complex task, as both, supply and demand side must be diligently analysed. Since both typically fluctuate with seasonal changes, time of the day, or
production cycles, it is recommended to assess not only a few selected operating points but to evaluate realistic scenarios with a resolution that captures significant changes in all parameters. You may also want to include sensitivity analysis to ensure that the results also contain data representing conditions deviating from the current or expected situation.
Careful consideration is good, but comprehensive simulations are better. The ENEXSA Heat Pump Library gives you far more than just name plate performance.
Together with the
EBSILON heat balance software which provides powerful interfaces to MS Excel and Python, you can run extensive automated scenario calculations and produce accurate and comprehensive information that you need to make the right decision when selecting industrial heat pumps and designing related energy systems.
