    YVAA chillers at Budapest One

    Budapest One is a groundbreaking office complex consisting of 66,500 square feet of office park with a unique facade and structural design located at Őrmező, Budapest's “western gate”. The area contains Hungary's largest multimodal transport intersection.  In collaboration with developer Futureal, we delivered an innovative and efficient HVAC solution to ensure the building is comfortably cooled.  With the installation of 10 best-in-class YVAA chillers and the central OpenBlue management system, we continue to optimize energy consumption while reducing costs.

    Quick Start

    After power is interrupted, it can take a standard chiller up to 10 minutes to restart. But with the Quick Start feature, YVAA chillers can restart within seconds after power is restored. YVAA chillers feature an industry-leading compressor restart (upon power being restored) of 34 seconds.

    Because YVAA chillers contain a variable-speed drive, there is no inrush of current. As a result, all compressors can be started together. This allows a faster ramp-up to full capacity than possible with a typical chiller.

    Variable-speed Drive

    VSDs help reduce energy consumption – particularly at off-design conditions – and can help lower annual energy costs as much as 50%. Our patented, liquid-cooled VSDs also require less maintenance, with glycol replacement required only every five years. And the variable-speed design dramatically reduces sound levels at off-design conditions – up to 16 dBA. Designed and manufactured by Johnson Controls, a 100% liquid-cooled VSD is standard on the YVAA.

    Proven Compressor Technology

    The YVAA incorporates advanced, patented variable volume index (VI) technology in a proven design. Our VI design optimizes the compression ratio of the compressor to match the conditions between the evaporator and condenser. This optimized compression ratio prevents over-compression to minimize energy consumption. Every compressor is run-tested at the end of the production line to ensure reliable operation.
