Eco-Desing and Seasonal Efficiency
TCGB0136 rev.1 - 05/2021

Seasonal Energy Efficiency Ratio (SEER)
in cooling and the
Seasonal Coefficient of Performance (SCOP)
in
heating give a more accurate estimation of the real performance of the equipment during the whole period of usage, all
while considering:
• Several points of measure (In cooling mode: an outside temperature of 20ºC, 25ºC, 30ºC and 35ºC; in heating mode:
an outside temperature of +12ºC, +7ºC, +2ºC, and -7ºC.
• Different compressor speeds (full load and partial load), auxiliary consumption (crankcase heaters, thermostat off
mode, OFF mode…).
• Conditions of temperature (number of hours per outdoor temperature) for an identified climate (average climate for
ErP compliance)
• Building heat load (called Pdesign)
Hitachi, in compliance with the Eco Design Directive, has developed the new outdoor units: new UTOPIA series, whose
high efficiency level (including SEER and SCOP values) is properly informed to our customers to allow for an easy
selection.
New UTOPIA series offer high seasonal efficiencies, as well as complete flexibility, with all outdoor units from both ranges
being fully compatible with the System Free range of indoor units. Hitachi’s UTOPIA technology has all the benefits of
VRF, including individual control of each indoor unit with an increased number of indoor unit combinations in addition to
delivering excellent part-load efficiency.
With cooling capacities and heating capacities from 2HP to 12HP, a maximum of 4 indoor units are connectable
to a single outdoor unit, with individual control and efficiencies achieved as high as A++/A+ (depending on model/
combinations).

The
Energy label
is the regulation compliant way of displaying product efficiency and sound level to any point of sales.
This label displays 3 European climates: average climate (green), cold climate (blue), hot climate (orange). Regulation
requirement is to display any information related to performances on average climate.
