Điều hòa chính xác Liebert P2070DA
– Exceptional efficiency at partial load, almost 25% more efficient than other
– Regulation of the inverter driven compressor between 30 and 100% of the rated
– Microchannel based evaporator coil with multiple electronic expansion valves maximize heat transfer and minimizes power
EC Fan
– The unit is equipped with a direct, high efficiency, single inlet, backward curved, centrifugal plug type innovative EC fan(s).
– The EC fan technology regulates airflow and reduces the fan input In- floor configuration further reduces energy consumption in downflow units.
– Liebert EC 2.0 fan modulates the fan speed according to load density; saving nearly 30% of energy
Enhanced efficiency achieved with a new evaporator coil design Introducing an Aluminium Microchannel Coil, first ever used in PEX design
– Microchannel coils are 40% smaller, 40% more efficient, and use 50% less refrigerant than standard tube and fin
– Multiple micro channels improve heat
– Flat tube results in lesser air side pressure drop, less power
– Compact design & less also resulting in reduced unit
– Each cooling module consists of a “V” shaped microchannel coil & is configured with two EEVs with common More than 60kW capacity PEX4 unit does have two cooling modules with dual electronic expansion valves in each module with same driver arraignment for two EEVs.
Inverter Compressor
– Optimized variable speed design through efficient BPM motor, wide speed range 1000 ~ 7200 RPM for part load efficiency.
– Expanded operating envelope for a wide range of cooling applications also contributes to premium efficiency. Special care is taken for EMF with filter.
– Intelligent oil circulation logic during low speed performance &
– Coupled with environment friendly refrigerant (R410A) & EEV, premium efficiency is achieved as compared to legacy solution; part load COP as high as > 5.
