Two of the Australian chain’s 39 transcritical stores are retrofits, as it tackles refrigerant emissions.
Frascold parallel compressors, heat reclaim, hot-gas defrost and solar panels cut electrical costs of cold-storage facility.
The company made over 20 transcritical CO2 systems in 2020.
The new fittings have a special looped plate wall, and a 180° return bend, which does away with potentially hazardous ‘dead legs’ in heating and potable water.
Hussmann Oceania follows Panasonic’s introduction of the unit in Europe two months ago.
Michael’s SUPA IGA store’s transcritical CO2 HVAC&R system is seen as more efficient than R404A systems.
Patton also cites lack of training on digital systems.
The installation, with ejectors and parallel compression, is for Australian retailer Tong Li Supermarket.
FTE system is expected to offer 7-10% energy savings compared to standard transcritical system
