Three major technology trends in the computer room air conditioning market
Guided by these demands, the computer room air conditioning market has shown the following technological trends in recent years:
High heat flux density – e.g. for inverter compressors in inter-row air conditioning. Emerson's inverter compressor and drive system solutions dramatically shorten system design cycles, reduce design costs, and accelerate time to market.
High energy efficiency and low PUE - inverter/parallel/digital, etc., increase part load, broaden the operating range of high evaporation temperature of products, and use energy-saving certified products such as high-efficiency vortex.
Refrigerant switching – the use of R410A environmentally friendly refrigerant is the next step in the development direction.
Combining "1+1" Emerson inverter solutions
