Specifications
Vertiv Liebert® DA series is a large cooling capacity, high efficiency and energy-saving room-level precision air conditioning products, single unit cooling capacity of up to 200kW, using a breakthrough innovation of a new generation of natural cooling energy-saving technology, based on the full inverter fluorine pump natural cooling technology, after a comprehensive logic and equipment structure upgrade was born. We deeply exploit the natural cooling potential of fluorine pump, and make full use of outdoor natural cooling resources through pre-cooling + supplemental cooling mode, increasing the utilization time of natural cooling by 40% throughout the year and minimizing the power consumption of the whole machine. With the hybrid dual-engine heat pipe technology, the energy efficiency of the unit can be improved by over 15% throughout the year.
Benefits
Larger cooling capacity per unit of surface width, single unit cooling capacity up to 200kW
Energy-efficient "hybrid twin engine", with a 15% increase in annual energy efficiency
Reduced number of air conditioners, fewer copper pipe connections, lower TCO
Easy installation and maintenance, full frontal maintenance of the unit
Features
New generation inverter scroll compressor, inverter compressor for high return air conditions, higher evaporation temperature (27 degrees) and higher energy efficiency.
Full inverter components: new generation EC fan, inverter fluorine pump, electronic expansion valve, reliability and energy saving significantly improved.
Heat exchanger with double coil laminated structure, FreeCooling pre-cooling, DX system flexible make-up cooling according to demand, more full use of natural cooling.
Full frontal maintenance, side-by-side installation without spacing, compatible with up and down ducting, up and down wiring, horizontal air supply without raising the floor.
The fan modules are installed separately, which increases the spacing between the fans, resulting in smoother internal airflow organization, less wind resistance and more energy saving.
Equipped with full-time natural cooling technology, fully automatic adjustment with the change of outdoor ambient temperature and indoor heat load to achieve the best matching energy saving.
Optimized control logic, during mode switching, the temperature control fluctuation deviation of the machine room is less than 2 degrees, and the normal operation temperature deviation is less than 1 degree.
compressor mode dehumidification, mixed mode dehumidification, dehumidification is more accurate and efficient, the evaporation temperature of the system is lower, dehumidification while taking into account refrigeration.
dual system design, intelligent distribution of cooling capacity, each system can work independently and as a backup to each other, more reliable.
Centralized condenser, modular installation, land-saving and low noise.
