A new inverter screw water-cooled chiller range has been put on the market, achieving a high energy efficiency, especially at part load, typically 97% of the operating time.
Anticipating future regulatory requirements, it has been designed for use with HFC-134a or the lower GWP drop-in R-513A (GWP 631).
The new chiller is up to 15% more efficiently than other existing systems, and can achieve an EER (Energy Efficiency Ratio) of 5.7 at full load, with an ESEER (European seasonal energy efficiency ratio) of up to 8.3 at part load.
The chiller design incorporates inverter technology and a high efficiency flooded-type heat exchanger, and optimizes unit performances by adjusting the discharge pressure of the compressor to the condensing pressure.
Besides cooling, the chiller can also produce hot water up to 65ºC.
