Energy Transfer Media
Many air conditioning and heat pump systems use
secondary medias such as air or water to transfer energy from and to
the space being conditioned. However, the transfer of energy from
one media to another can result in significant efficiency losses.
Daikin’s ‘DX’ air conditioning and heat pump
systems avoid secondary media transfer losses.
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. A c.80% heat recovery efficiency includes
both latent and sensible heat energy.
Daikin Inverter Control
There are two ways to control the operation of
the compressor in a direct expansion system
-
By stopping and starting (all ON or all OFF)
from a signal from the room thermostat
-
By changing the frequency of the electrical
supply via inverter to the compressor, hence the speed to achieve
the exact cooling/heating requirement. Benefits
include:
- Low start currents - Increased COP at low load
- Input matched to load - Maximum energy
utilisation
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.
Air to Water Heat Pumps
The Daikin Altherma air-to-water system is based
on micro-generation heat pump technology and represents a flexible
and cost effective alternative to relatively inefficient, carbon
intensive fossil fuel boilers. The energy efficient characteristics
of Altherma, makes it an ideal solution to substantially reduce
energy consumption and CO2 emissions in any residential and certain
commercial developments. See www.spacealtherma.com
Chilled Water Systems
Daikin’s recently extended range of over 300 air
and water-cooled liquid chiller models (nom. capacities 5kW to 2
MW), 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, Daikin’s screw compressors only require service
inspection at 40,000 hr intervals. All Daikin chillers benefit from
a 3 year warranty as standard.
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 computerised 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.
