ERQ PAIR AND VRV
AIR HANDLING APPLICATIONS
For small to large commercial spaces Daikin offers a range of R-410A inverter condensing units for use in conjunction with air
handling units. In situations where Daikin commercial range ventilation units cannot satisfy the ventilation requirement due
to building constraints (large atriums, banquet halls etc), air handling units represent the ideal solution.
Air handling units provide large fresh air volumes (> 1,000 m/h) and high ESPs enabling the use of extensive ductwork runs.
For more information on Daikin air handling units refer to the air handling unit catalogue.

BENEFITS OF ERQ AND VRV
AIR HANDLING APPLICATIONS
HIGH EFFICIENCY
Daikin heat pumps are renowned for their high energy efficiency with
COPs up to 4.56 in heating
1
. The VRV range offers both heat pump
and heat recovery units with part load efficiencies as high as 9.02.
Integrating the AHU with a heat recovery system is highly effective
since an office system can frequently be in cooling mode while the
outdoor air is too cold to be brought inside in an unconditioned state.
In this case heat from the offices is merely transferred to heat up the
cold incoming fresh air. In the absence of an AHU this ‘free heating’
the incoming fresh air would not be possible.

HIGH COMFORT LEVELS
Daikin ERQ and VRV units respond rapidly to fluctuations in supply air temperature, resulting in a steady indoor temperature
and resultant high comfort levels for the end user.
EASY DESIGN AND INSTALLATION
The system is easy to design and install since no additional water systems such as boilers, tanks and gas connections etc are
required. This also reduces the total system cost.
TOTAL SOLUTION CONCEPT
Integrating an air handling unit into the total building climate system enables both design and installation procedures to
based on a single common technology. This simplifies project follow-up, installation, commissioning and maintenance since
only one party is involved.

heated up for free by heat
recovery via A/C system
Indoor temperature 22°C,
needs cooling because of
solar radiation.
The excessive heat can
be transferred to the AHU
