AUSTRIA: Daikin has provided two screw inverter chillers working on Very low GWP HFO refrigerant R1234ze to a key pharmaceutical company’s facility in Vienna, Austria.
The two EWAH-TZ chillers with a total cooling capacity of 580kW to replace a 15-yr-old R410A chiller with distant air-cooled condensers. The refrigerant demand in the aged chiller was really higher and the reciprocating compressor only experienced 4 ability techniques.
The finish user resolved to swap it with additional innovative technological know-how, trying to get better electricity performance and environmentally friendliness.
The venture essential an environmentally-pleasant HVAC principle and the marketing consultant was amazed with Daikin’s screw inverter methods employing its dependable and energy successful in-household designed HFO screw compressor.
The chiller will be made use of to develop chilled drinking water/glycol combination at -8°C, which will give cooling for microbiological procedures. The cooling need varies from somewhere around 70kW to 570kW.
One more critical aspect was the noise reduction. The venture expected a highest seem electrical power of 81dBA. That necessity was tackled many thanks an optimisation of the lessened sound configuration in the TZ Series.
