Airflow Configuration
Air Quality and Distribution
The IPAC range is fitted with EU4 filters to provide air quality control,
with the option of EU, EU7 (higher filtration levels are available, but will
be located in an external filter
section).
The
units
are
fitted
with
a
fan/motor
combination
capable
of
supplying
the
design
airflow
against the
external
resistance
of
a
typical air distribution system
as well as
providing a quantity of fresh air into
the
conditioned
space.
All Year Round Operation
IPAC units are designed to operate
24 hours a day, all year round, in any mode (i.e. cooling/heating/ dehumidification/humidificati
on) and come complete with condenser fan speed and pressure control to avoid problems associated with over condensing during winter cooling.
Cooling, Cooling with Heating or Full Air Conditioning
Different applications require different modes of control and the IPAC range is available in three basic configurations:
● Cooling only (cooling unit).
● Cooling with heating
(temperature unit).
● Cooling with heating and humidification/dehumidification
Air-Cooled Condensers
A matched range of air cooled condensers are available for operation in ambient temperatures up to 35 °C. However, for higher ambients, uprated air-cooled condenser(s) can be supplied.
Ease of Maintenance
In

environments
in
which
air conditioning
units
are
installed
it
is
essential
to
carry
out
regular
maintenance
for
optimum performance.
As well
as
using
top quality
components,
ease
of maintenance
has
been
designed
into
these systems.
The
controller
automatically indicates
when maintenance
is
required
on
individual components and all servicing
can
be
carried
out
through
the
front
door(s)
of
the
unit.
Selecting a System
The overall building services design will define the type of cooling system required. As standard, the
IPAC range is available in three basic systems:
● Direct expansion cooling with air-cooled condenser.
● Direct expansion cooling with water-cooled condenser.
● Chilled water coolingAir Quality and Distribution

All Year Round Operation
IPAC units are designed to operate 24 hours a day, all year round, in any mode (i.e. cooling/heating/ dehumidification/humidificati
on) and come complete with condenser fan speed and pressure control to avoid problems associated with over condensing during winter cooling.
Temperature Control
IPAC units are designed to operate at room temperatures from 18 °C to
30 °C as standard and with factory added options can operate outside this range. Temperature can be precisely controlled, with cooling provided by a chilled water system or a DX unit with an external air-cooled condenser (option of water-cooled condenser available). Where heating is required, the alternatives of electric or low pressure hot water heating are available.
Humidity Control
Where humidity control is required, the IPAC unit is factory fitted with the facility whereby the cooling coil is operated below the dew point of the conditioned air to provide dehumidification. To ensure optimum temperature control in conjunction
with dehumidification the options of hot gas or electric reheat are available.
The unit can also be fitted with a proportional output humidifier to provide clean sterile steam. The humidifier responds to a changing demand using the water level (WL) system of modulation. Output is varied by increasing or decreasing the level of water in the cylinder. A decrease in water volume causes less electrical energy (measured in amperes) to pass between the electrodes, transforming less water into steam. An increase in water volume, logically, has the opposite effect. WL can modulate down to 20 % of full output.
Controller
The Eaton-Williams controller is a purpose designed LonWorks™ microprocessor, which fully complies with EEC directives for electromagnetic compatibility (EMC).
The controller is powered from a
9 V and 24 V 50 Hz power supply, these are provided via a transformer mounted within the electrical chassis.
All outputs are protected by shrouded fuses.
The Controller Hardware
Consists of:
● Display and push-button assembly.
● Microprocessor controller assembly.
The Controller Includes the
Following Features as Standard:
● Temperature and humidity set point adjustment.
● Dead band adjustment.
● Proportional band adjustment.
● Alarm band adjustment (individually for temperature and humidity).
● Fault and service alarm volt-free contacts.
● Winter low pressure switch delay timer adjustment.
● Start delay timers.
● Historical alarm logging.
● Lon network communications.
● Stand-alone or Master/Slave.
●
Run/Standby
and
duty
rotations.
Duty
Range
The IPAC range has been developed to provide a flexible duty range of units.
● Stand alone units currently range from a nominal 15 kW to 80 kW.
● Master/Slave combinations extend the range for larger applications.
Precision Air Control Equipment
The IPAC floor standing units are in their most basic form available in chilled water or DX cooling only configuration. These systems can either be mounted inside the conditioned space or mounted remotely, with the fan developing external pressure to transport the air to the conditioned space. Units can be manufactured with an upflow or downflow air pattern to enable optimum comfort levels. Depending on the application, heating, dehumidification, humidification and air filtration can also be provided.
As well as the standard unit configurations, a variety of options can be factory or site-fitted to customise units to the system requirements. This provides the designer, installer and customer with a system that can precisely match the requirements.
The Invicta Precison Air Control (IPAC) range of floor standing units has been developed to satisfy the exacting standards
for full function air conditioned environments.
