Title: “Sustainability and the Compressor Industry”
Rather belatedly, the whole world has woken up to the ‘climate crisis’ that was first brought to our attention 30 years ago. This keynote address follows up on the inspiring speech by Baroness Brown, at the Gala Dinner at the 11th Conference, in highlighting the crucial importance of doing everything possible to mitigate global Climate Change. Since the 12th Conference takes place just a few weeks before the delayed COP-26 international summit in Glasgow, it is imperative that ‘sustainability’ in the compressor industry becomes a dominant feature of this Conference.
As a businessman who is both a Chartered Engineer and a Chartered Environmentalist, Ian Arbon draws on his decades of international experience in the compressor industry and in sustainable development, renewable energy and climate change mitigation/adaptation to define what is really meant by ‘sustainability’ (significantly more than so-called ‘decarbonisation’) and propose a strategy for the future development of the industry, which includes:
- Energy conservation / demand reduction
- Energy efficiency
- Sustainability of materials of construction
- Sustainability of energy supplies
- Sustainability of operating fluids
- Sustainability of manufacturing processes.

Title: Challenges for Compressors in Heat Pump Applications
The drive to decarbonise energy use has prompted an increase in the use of heat pumps of all types and sizes. The benefit of a heat pump in this case is twofold.
The “heat advantage” of the heat pump means that more energy is supplied as heat than is used in operating the system, so there is a beneficial ratio compared with burning gas, not only in emissions but also in operating cost compared to other alternatives to gas.
If the heat pump is electrically driven then the carbon emission caused by the heat supply is related to the generation of the electrical power and so can be much cleaner than burning fossil fuel for direct heating.
For compressor designers and manufacturers the drive towards higher condensing temperatures in vapour compression heat pump systems presents some challenges.
These include higher operating pressures, higher internal temperatures and a greater emphasis on operating efficiency and reliability. These challenges stem in part from the technical circumstances of heat pump operation but are also due to commercial and regulatory requirements.
This keynote address explores the ways in which these challenges have been tackled in the recent past and presents some notable successes in this application. It then addresses the topics that are not yet mastered and considers what development effort is still required in order to make further progress.

Title: Heat Pump and its Role on Carbon Neutral Target
The world is facing carbon neutral in the middle of this century, carbon neutral does not mean zero carbon emission, it means carbon emission could be absorbed by carbon sink. It is clear that the world will be more powered by renewable energy (50% or more in 2050), electrification would be affordable and accessible and could be extended its applications.
Fossil fuel should be treated for less CO2 emission by increasing energy conversion efficiency, and wide uses of heat recovery devices to use low grade heat both from waste heat or solar heat or even from the ambient becomes vital. Heating and cooling are the most demanded energy for end users, such as buildings, industries and also transportations, heat pump is truly the most effective equipment for decarbonization.
This report will present:
- Heat pumps based on electric vapor compression systems: air source heat pump water heater, air source heat pump heating and cooling for residential and commercial buildings, other various low grade heat source heat pump (such as ground source, water source and etc..), waste heat recovery heat pump for industry heating;
- Heat pump based on thermal driven systems: LiBr-water and water-ammonia absorption heat pumps for efficient waste heat recovery for industry application, and solar cooling;
- Chemical heat pumps based on thermal energy for heating, cooling, thermal energy upgrading, and thermal storage;
- Next generation heat pumps for air conditioning with coupled sensible and latent thermal load handling, its doubled efficiency for heating and cooling could be applied in residential/commercial/transportation heating and cooling;
- Air source heat pump or waste heat recovery heat pump for steam generation, which may bring a new feasible way to use electrified heat pump to replace small to medium scale fossil fuel based or electric heated boilers.
Heating/cooling decarbonization is a major challenge for China to meet its 2060 carbon neutral commitment, heat pump represents a promising solution for heat/cold supply in various building and industry applications.
Our results reveal that the decarbonization potential from heat pump in a carbon neutral China future could reach around 1400Mton and 600Mton for residential and industrial heating respectively, which add to 20% current carbon emission in China.
It is also shown that achieving such deep decarbonization of heat pump requires ad-hoc interventions that balance technology advancement, techno economics, policy incentive, and integrated short-term and long-term decision making. This research has shown that heat pump could play a key role in carbon neutral target.

Dr. Colin Brown, Institution of Mechanical Engineers
Title: ‘The Engineer in Society’
It is often said that many societies undervalue the contribution that engineers make to wealth and wellbeing. In 2018 the Institution of Civil Engineers ran a campaign called ‘Invisible Superheroes’ which centred on the behind the scenes status that many engineers feel they have.
And yet in contrast there are cultures where engineering is seen as an aspirational vocation by both parents and children. It has high status and indeed engineers have a significant role in Government.
This talk reflects on the multiple perceptions that engineering can generate including its ability to do harm as well as good. The aim is to draw out some themes that enable engineers and engineering to ensure they are always as good as they can be.
