PUSCH Workshops at the Asia Pacific Solar Research Conference



Overview

Promoting the Use of Solar Cooling and Heating (PUSCH) in Australian buildings is an ongoing effort supported by the Australian Renewable Energy Agency (ARENA) to help improve the market uptake of these technologies. As a part of this project, an industry roadmap is under development. This roadmap has identified few potential barriers and opportunities for improving the market uptake of solar heating and cooling technologies. 

These seminars form part of the Asia Pacific Solar Research Conference, and provide an opportunity to look at some of the global initiatives that could be adapted to Australian market conditions. Activities coordinated through the International Energy Agency Solar Heating and Cooling Program (IEA SHC) will be discussed. 



Presenters 

Seminar I: 11am to 12.30 Price reduction of solar thermal systems (IEA SHC task 54)
Korbinian Kramer, Fraunhofer ISE, Germany
Although solar thermal is already very well developed and has a high market penetration, costs are always an issue when it comes to deciding which heating system to use. IEA SHC Task 54 aims at a cost reduction for end-users of installed solar thermal systems by evaluating and developing sustainable means to reduce production and/or installation costs on material, sub-component, system-component and system level. Special emphasis is placed on the identification and reduction of post-production cost drivers, e.g., channels of distribution. Extensive market research, including defining reference systems, cost analyses, and the study of socio-political boundary conditions for solar thermal prices in selected regions will provide the basis for the evaluation of cost-structures and the cost-reduction potential. The main activities and achievements will be presented.

Seminar II: 2pm to 3.30pm: Solar district heating (IEA SHC Task 55) 
Jan Erik Nielsen, SolarKey Int., Denmark
For quite some time now district heating has been widely used in many European and Asian countries. Traditionally these systems use fossil fuels, but in many places these have replaced by renewable energy: solar, biomass and heat pumps (on renewable electricity). Some rather large solar district heating systems have been installed in Northern Europe. The biggest to date is 157, 000 m² (110MW). A project with almost 500,000 m² (350MW) is being prepared. And because it is now possible to store the heat from summer in underground storages to use in winter, solar fractions of more than 50 per cent are now possible. The principles for these solar/renewable systems will be demonstrated and some examples shown – including a solar district cooling system. The ongoing activities in the international group IEA SHC Task 55 will be presented.

Overview

Heating and cooling systems account for over 40 per cent of commercial building energy usage in Australia with significant impact on building star rating. Solar energy can reduce building energy consumption, and solar resource availability has a natural fit with the cooling needs of a building. 

There are many ways to take advantage of solar. However, introducing solar creates additional design considerations and requires greater integration of building services and architectural design disciplines. A holistic approach during design stage will result in easy adaption of energy efficient technologies in buildings. 

In this seminar, participants will gain an understanding of available solar cooling and heating solutions for integration with commercial and residential buildings. The seminar will provide guidelines for incorporating sustainable heating and cooling solutions while designing a building envelope. Real world examples from CSIRO installations from Australia and global installations from International Energy Agency task 53 (IEA) will be discussed during the seminar. 

Participants of this seminar will be able to: 
  • Gain familiarity with market available solar cooling and heating solutions 
  • Recognise the design and installation requirements of sustainable heating and cooling technologies in buildings 
  • Include sustainable heating and cooling solution options in the conceptual design stage of a building.

AIRAH and Standards Australia presented a seminar series in February and March on the recently adopted and published refrigeration safety and environmental standards; AS/NZS/ISO 817:2016 Refrigerants – Designation and safety classification which replaces AS/NZS 1677.1:1998 and AS/NZS 5149 Refrigerating systems and heat pumps – Safety and environmental requirements: Parts 1 to 4, which replaces AS/NZS 1677.2:1998. 

Each of these new adoptions have had major modifications and revisions over the previous AS/NZS1677 series and are critical as we move to low global warming potential refrigerants.  AIRAH will be holding the update seminars throughout Australia in February and March 2017 to provide an introduction and overview to the main changes that will affect the HVAC&R industry.


Highlights of the seminar:

  • Changes to refrigerant safety classifications
  • Changes to safety and environmental standards

The AS/NZS 5149 standard is published in four parts comprising over 160 pages of technical safety and environmental requirements under the general title, Refrigerating systems and heat pumps – Safety and environmental requirements:
  • AS/NZS 5149.1:2016 Part 1 Definitions, classification and selection criteria
  • AS/NZS 5149.2:2016 Part 2: Design, construction, testing, marking and documentation
  •  AS/NZS 5149.3:2016 Part 3 Installation site
  • AS/NZS 5149.4:2016 Part 4 Operation, maintenance, repair and recovery. 

Standards Australia will also provide an outline on the following topics:
  • Standards Australia overview and how Standards are developed
  • Background to AS/NZS ISO 817 and AS/NZS 5149 projects
  • Engagement and participation with standards development.
