دانلود کتاب High Temperature Heat Pumps for the Australian food industry

The purpose of this report was to define the likely feasibility, and range of applications for heat
pumps in the food industry, with a focus on high temperature (HT) heat pumps delivering useful
heat at 66oC-150oC.
This work is a continuation of the 2xEP project investigating the opportunities for innovation in
technology/business models that could transform energy productivity in the food value chain
(http://www.2xep.org.au/innovation-next-wave.html). The first overview report defined one key
transformative change as being the electrification of food processing, displacing fossil-fuel fired
boilers and steam systems. One central technology required for this transition is the application of
heat pumps to recover heat from waste streams to boost temperatures, displace steam, and in some
cases simultaneously provide process cooling.
This work is particularly important at a time when East Coast Australian companies have seen a
significant rise in gas prices in the last two years, with prices often more than doubling. As heat
pumps effectively use electricity to harness heat from waste heat streams or the environment at
efficiencies of over 300%, they can cost effectively displace gas when gas prices are high (and when
the cost of renewable electricity is falling rapidly – as solar PV can be used to power heat pumps).
The project team consulted extensively with stakeholders and conducted research to define
international best practices in heat pumps technology and application globally and to understand
the experience and capacity in Australia. We then evaluated the likely economic return from using
heat pumps in a range of applications locally. This evaluation is at pre-feasibility level. Based on a
successful outcome of this project, we could potentially pilot heat pumps in the most promising
applications with strong replication potential.
