Star Refrigeration NH3 system wins ‘Refrigeration Project of the Year’

Star Refrigeration has won ‘Refrigeration Project of the Year’ at the UK’s National ACR & Heat Pump Awards 2019 for a low-charge NH3 installation at a winter sports centre.

Glasgow-based Star Refrigeration has won the ‘Refrigeration Project of the Year’ award at the National ACR & Heat Pump Awards 2019 for its Azanechiller 2.0 low-charge ammonia installation at the Snozone winter sports centre in Milton Keynes.

Snozone Milton Keynes is an indoor skiing and snowboarding venue that ranks among the UK’s top indoor leisure attractions. In 2017, two ammonia-based Star AA415MTE-1 Azanechiller 2.0 units replaced the original chillers based on R404A, an HFC blend being phased down under the EU’s F-Gas Regulation.

“it’s an honour to accept this award on behalf of all of the Star team who worked incredibly hard on this project,” said Alan Walkinshaw, special projects sales manager, Star Refrigeration.

The awards, organised by Britain’s ACR Journal, are considered the UK’s most prestigious in the HVAC&R sector. Star Refrigeration was in the running for three awards. The awards ceremony was held in Manchester on 24 January.

“Snozone was a great project with a heavy cooling demand and we were always confident that the Azanechiller 2.0 was the best solution,” said Walkinshaw, who was responsible for the installation.

Ice and leisure is just one growing sector which can utilise the power of the Star Azanechiller 2.0.

Strong growth in ice and leisure market

The Azanechiller 2.0 boasts a capacity of 360 kW and chills ethylene glycol from -10°C to -13°C. Vahterus plate and shell heat exchangers help to minimise the ammonia charge to only 85 kg per chiller. Acoustic enclosures around the compressor/motor assembly combined with EC condenser fans present the lowest noise outlay possible for the retrofit installation.

“Ice and leisure is just one growing sector which can utilise the power of the Star Azanechiller 2.0,” Walkinshaw said.

In only four months, Snozone saved 56% on electricity bills thanks to the efficiency of the Azanechiller 2.0. It has also reduced CO2e emissions by 700 tonnes.

The Azanechiller 2.0 exceeds Europe’s Eco-Design Minimum Energy Performance Standards (MEPS) requirements by 74-146% depending on the application and operating temperature.

The Snozone facility contains 1,500 tons of snow and ice, which has to be maintained at -4°C air temperature for optimal operation. (For more on the prize-winning installation, see ‘Low-charge NH3 chillers deliver energy savings at Snozone’, 3 December 2018.)
