Split & Multi-Split Heat Pump Systems
Air source heat pumps are now classified as LZC (low to zero carbon)
renewable technologies, as such they can help in meeting the
requirements of the latest building regulations whilst qualifying for
Enhanced Capital Allowances and reduced rate VAT.
Ideal for small to medium sized properties of all types, split and
multi-split systems can operate up to 5 indoor units from a single
outdoor unit providing heating and cooling for year round comfort.
Operating with the safe, stable and efficient refrigerant HFC R410A and
incorporating inverter technology, these systems offer industry-leading
performance and efficiencies. A comprehensive range of stylish compact
and extremely quiet indoor fan coil units, including the new round flow
cassette is available.
The Daikin Altherma split air-to-water system is based on
micro-generation heat pump technology and represents a flexible and cost
effective alternative to a fossil fuel boiler. The energy efficiency
characteristics of Altherma, makes it an ideal solution to dramatically
reduce energy consumption and CO2 emissions. See

VRV (Variable Refrigerant Volume) Systems
Daikin VRV heat pump and heat recovery systems provide the ultimate
in space saving, energy efficient climate control systems, from the
average size residence to the largest of buildings. VRV systems use
inverter controlled scroll compressors resulting in the industry’s
highest COPs (coefficient of performance) ratings.
The VRV range includes a water-cooled version (VRV-WII), which uses
water as its heat source and VRVIII. The third generation VRV offers
even more design flexibility through a number of technological
advancements including increased capacity, longer pipe length
capability, greater fan coil connectivity (up to 64) and enhanced energy
efficiency. The system features automatic refrigerant charging with
built-in leak detection and the refrigerant content has also been
further reduced, all of which aids compliance with the F-Gas Regulation.
The mini VRV (VRVIII-S), bridges the gap between the multi-split and
larger capacity VRV systems. Up to 9 fan coil units can be connected to
the mini VRV system.
Daikin Inverter Control
The frequency Inverter Control in Daikin systems reduces energy
consumption by at least 30% compared to non-inverter types. The inverter
improves performance relative to power input, ensures a more even room
temperature and eliminates power surges and stop/start cycles. Inverter
technology maximises operating efficiency so important in these times of
environmental consciousness and the need to reduce carbon emissions.

Heat Reclaim Ventilation (HRV)
Efficient ventilation is a key element of the new Part F and Part L
Building Regulations and Daikin’s heat recovery ventilation modules can
be applied as stand alone units or incorporated within the air
conditioning system.
Temperature and humidity are exchanged between the supply and exhaust
air, recovering potential energy losses and considerably reducing the
air conditioning loads. The HRV modules feature a high efficiency VAM
heat exchanger and are available in 4 models with airflow rates from 350
to 2000 m3/h and with optional DX Coil and humidity control.
Chilled Water Systems
Daikin’s recently extended range of over 300 air and water-cooled
liquid chiller models (nom. capacities 5kW to 1.9MW), now include
inverter scroll and/or inverter stepless screw compressor technology for
improved capacity control and therefore greater part load efficiency.
Renowned for high reliability and low maintenance costs, Daikin’s screw
compressors only require service inspection at 40,000 hr intervals.
Daikin’s Integrated Chiller Network (DICN) allows the simultaneous
operation of up to 4 chillers as if they were a single unit. This
results in precise and efficient capacity control and is useful for
back-up purposes, ensuring that only the necessary amount of cooling is
supplied and guaranteeing the optimum operation of the chiller plant.

Daikin Control Systems

A comprehensive range of advanced controls complements Daikin air
conditioning systems. The I-Manager is a computerized control system for
Daikin’s VRV systems, operating up to 1024 indoor units and allowing
precise control, simple settings and operating functions. The
Intelligent Touch Controller is a stand alone, plug and play system
operating up to 64 indoor units at the touch of the screen. The Daikin
DS-net intelligent monitoring control system can give the Facilities
Manager access and control to 50 sites.
The Carbon Trust & ECA (Enhanced Capital Allowance)

Managed by The Carbon Trust, the Energy Technology List includes
various technologies that meet predetermined efficiency requirements.
Many Daikin VRV, split, multi-split heat pump systems and chillers
qualify for Enhanced Capital Allowances. See www.eca.gov.uk/etl.
