Hitachi GLS Refrigeration and Freezing Unit Ceiling Integrated Inverter Standard
Hitachi Global Life Solutions
Ceiling-mounted integrated refrigeration and freezing unit that achieves high energy efficiency with the adoption of R410A inverter technology.
Adoption of refrigerant R410A with consideration for earth environmental protection (global warming mitigation, CO2 emission reduction) Ozone depletion potential: zero, global warming potential: 2,090, which is about half of R404A Reduction of annual power consumption Equipped with R410A DC inverter scroll compressor and high-efficiency control through the use of electronic expansion valve, achieving high energy-saving performance 15-23% increase in cooling capacity (for 50Hz) The increase in cooling capacity allows for accommodating temporary storage increases compared to fixed-speed units. The pull-down (cooling) performance has improved, shortening the time to reach the set temperature. Expansion of the lower limit of the outdoor temperature range to -5°C By adopting control of the rotation speed (capacity) of the compressor and condenser fan, the lower limit of the outdoor temperature has been expanded. Expansion of the upper limit of the indoor temperature range for refrigeration to 20°C Consolidation of two models for fixed-speed units for high temperature (5-20°C) and medium temperature (-5-15°C) refrigeration into one model.
