Oatmill Cinema

Mount Gambier

2020

Application

  • Commercial Building Heating & Cooling

Sector

  • HVAC

Technology

  • CO2 Only Cooling and Heating

Brief

Oatmill Cinema is a cinema complex based in a historic building in Mount Gambier.

The building’s ageing Heating Ventilation and Air Conditioning (HVAC) equipment (>20 years) operated on ozone depleting HCFC refrigerant R22.

R22 refrigerant has been phased out under the Montreal Protocol,with no virgin imports into Australia since 2016. This has seen the price of R22 increase to over $400/kg. The building owners are left with the predicament of when replacing this aging equipment of which refrigerant to change to.  The most common replacement on the markets contain HFC refrigerants which are also been phased out due to their high Global Warming Potential (GWP).

Oatmill Cinema’s owners worked with Glaciem Cooling to evaluate the energy demands of the cinema complex.  A detailed economic analysis of energy demands and modeling of the performance of a new system was performed by Glaciem.

Scope

Glaciem’s solution was to install the Southern Hemisphere’s first direct expansion CO2 only system cable of providing simultaneous heating & cooling.

Due to the unique nature of the design the buildings existing HVAC infrastructure could still be utilised with only the heating & cooling coils requiring replacement. The utilisation of the existing HVAC infrastructure resulted in a >45% saving on the installation cost.  The new system is also estimated to reduce heating and cooling electrical operating cost 56%

Rowland Flat

2019/20 – ARENA ARP

Advancing Renewables with PCM Energy Storage

This project received funding from ARENA as part of ARENA’s Advancing Renewables Program.

Application

  • Barrel Storage, Packing Areas

Sector

  • Process Cooling

Technology

  • Phase Change Material Thermal Energy Storage (PCM TES)

  • Advanced Control & Forecasting Algorithm (ACFA)

Brief

Pernod Ricard’s Roland Flat facility is located in the Barossa Valley, SA, and has winemaking, wine storage and packaging capability.  Significant refrigeration is used to process the harvest during summer months from January to April.  Refrigeration loads decrease by about 70% outside of this period.  The existing refrigeration plant, Frig 9, operates year round, providing process cooling, barrel storage and air conditioning and has been identified as optimal for thermal storage integration.

This project involves the integration of a Glaciem thermal storage unit operating on renewable energy with the existing Frig 9 ammonia refrigeration plant to optimise process cooling techniques in a primary production context and reduce exposure to peak electricity costs.

Scope

  • install a new Thermcold DYN 900 unit to provide 2.6MWh of thermal energy storage
  • Integrate PCM TES with sites existing ammonia refrigeration plant
  • integrate this system with virtual and on-site renewable assets;
  • use 0 degrees PCM and Dynalene HC as the heat transfer fluid;
  • integrate ACFA with the site’s Building Management System (BMS) to allow the system to dynamically control the usage and storage of the site’s renewable energy.

Reef HQ, Townsville

2019/20 – ARENA ARP

Advancing Renewables with PCM Energy Storage

This project received funding from ARENA as part of ARENA’s Advancing Renewables Program.

Application

  • Heating Ventilation Air Conditioning (HVAC)

Sector

  • Commercial Buildings

Technology

  • CO2 Heat Pump

  • Phase Change Material Thermal Energy Storage (PCM TES)

  • Advanced Control & Forecasting Algorithm (ACFA)

Brief

A large portion of Reef HQ energy consumption is used by the existing HFC refrigeration chillers. These chillers provide chilled water-based air conditioning for the building and also cool 4 million litres of chilled seawater in the two main Aquarium tanks which are maintained at 28°C for optimum marine life conditions. The site currently has 256kW of installed PV and a zero-export limit.

The installation of PCM TES, a CO2 Heat pump & ACFA will store any access renewable energy, thus drastically reducing operating costs, maximising the economic potential of renewable energy assets and reduce direct and indirect CO2 greenhouse gas emissions.

Scope

  • install a new Thermcold DYN 420 unit to provide 1MWh of thermal energy storage using 0 degrees PCM
  • integrate this system with on-site storage of up to 75% of the solar PV;
  • install a new CO2 heat pump to run in parallel with the existing HVAC-R systems;
  • use 0 degrees PCM and Dynalene HC as the heat transfer fluid;
  • integrate ACFA with the site’s Building Management System (BMS) to allow the system to dynamically control the usage and storage of the site’s renewable energy.
  • Heating Capacity 48 kWr
  • Total Volume 80°C water 1000litres/day
