SPECIFICATION
COOL-PHASE® low energy cooling and ventilation system
COOL-PHASE® is a low energy cooling and ventilation system that reduces the running costs of
buildings and creates a fresh and healthy indoor environment. The system uses a thermal energy
store comprising of a phase change material (PCM) in combination with intelligently controlled
mechanical ventilation to actively cool and ventilate the building. The COOL-PHASE system has been
developed for use in the commercial, education and healthcare environments.
The COOL-PHASE system can maintain temperatures within the comfort zone, while radically
reducing energy consumption by up to 90%, compared to a conventional Air Conditioning system.
The reduction in energy usage combined with low servicing and maintenance costs and a long life
result in a strong financial case over traditional cooling approaches. Since no compressors or
hazardous coolants are used, the system also has a number of environmental benefits, while the lack
of external units means the COOL-PHASE system can be used where outside space or planning
permission is an issue.

7. Maintenance Instructions:
7.1. Maintenance Schedule:
After one year from installation a service agreement is required. If regular maintenance is not
carried out the warranty of the product will be invalidated. A typical maintenance schedule is shown
below. For any maintenance queries please contact: [e-mail]

7.2. Recirculation Air Intake Filter:
The Recirculation filter will be located within the Recirculation module at the point where the air
enters the building before being ducted to the COOL-PHASE unit –see project layout drawings for
individual locations. The filter is required to ensure both the quality of the ventilation air supplied to
the room and to protect the ducting and COOL-PHASE unit from the build up of dirt. If the filter is
dirty, a replacement should be fitted as it will inhibit the performance of the system. Changing filters
regularly will extend the life of the product. G4 grade filters are fitted as standard and replacements
can be purchased directly from Monodraught. Recirculation filter will need replacing at a minimum
of every 1 year, but will depend on the buildings location & the quality of external air. The COOL-
PHASE unit should be switched off prior to filter maintenance.
7.3. Thermal Battery Maintenance:
The Phase Change Material (PCM) is fully encapsulated to create a “Thermal Battery” and needs no
specific maintenance; it has a design life of 20 years and is guaranteed for 5 years subject to service
agreement.

9. COOL-PHASE Control Strategy
The COOL-PHASE® system is a mechanical cooling and ventilation system, utilising a seasonally adjusted
control strategy with thefollowing inputs;
Time
Date
Internal Temperatures
ExternalTemperatures
Internal CO2 levels
The system comes supplied with a wall controller for local user inputs and eachunitcan be run in either
Slaveor Master mode.
9.1. Zonal Control Strategy:
The COOL-PHASE system can be run as a standalone system supplied with 1N° wall mounted control
system serving a single room or area.
Multiple COOL-PHASE systems can be run alongside each other independently with their own wall
mounted control system, or a maximum of four COOL-PHASE units can operate in a master / slave
arrangement with a single wall controller providing user inputs. This allows multiple COOL-PHASE
units to operate in a single room or zone of a building.
9.2. Inputs:
The system uses the following inputs. Details of user controls are contained in Section 4.
9.2.1. Fire Alarm Input (Optional):
When the fire alarm is activated the COOL-PHASE system will automatically close down until the
fire alarm is deactivated the COOL-PHASE system will then return to automatic mode.
9.2.2. User Overrides:
The user can increase or decrease the fan speed when the system is active by pressing the
‘HIGH’ or ‘LOW’ button on the wall controller. Similarly, the system can be turned off for one
hour by pressing the ‘OFF’ button.
9.2.3. CO2Input:
If the CO2Level in the zone exceeds 1000ppm concentration level the system will increase the
flow of external air into the room until the CO2level is reduced to 900ppm levels
8.2.4 Temperature Input:
In the cooling season the system will monitor internal temperatures to provide cooling when the
temperature exceeds 23°C. The amount of cooling is determined by the temperature difference,
and the system will continue to cool to maintain comfortable indoor environment.

In the heating season the system will monitor temperatures to ensure they remain above the
heating set point (See system config setting).
8.2.5 Input Priority:
9.3. Control Inlet Dampers:
There are three positions for the inlet volume control dampers:
1. External Air –Air is brought in from outside the building only. No recirculation occurs.

2. Recirculation –Air is re-circulated within the room or space only. No air is brought in from
outside.
3. Mixed Air –Re-circulated air is
mixed with outside air. The volume controller dampers control the proportion of re-
circulated air to external air.

9.4. Outlet Air Paths:
There are two positions for the outlet control dampers:
1. Direct Ventilation –Air is passed directly into the room. No air is passed through the PCM
heat exchanger.
2. PCM Heat Exchanger –Air is passed over the PCM Heat Exchanger to charge or discharge the
thermal energy store before entering the space.

9.5. Operating Modes:
9.5.1. PCM Re-Charge Mode:
During the warmer months of the year and when the room is unoccupied at night the system
will automatically pull in external air and pass it over the PCM heat exchanger to re-charge the
COOL-PHASE thermal batteries.
9.5.2. Summer Pre-Cooling Mode:
During summer, Cool-Phase brings in cool air to pre-cool the fabric of the building, increasing the
cooling effect for the following day.
8.5.3 Cooling Mode:
Should the temperature in the room exceed the seasonal pre-set level, the system will provide
cooling proportionally to meet the requirements of the space by varying the damper positions
and fan speed.
Cooling is provided through the effects of free cooling (when the temperature outside is cooler
than inside) and by intelligently using the energy stored in the PCM heat exchanger to cool the
space.
8.5.4. Ventilation Mode:
Should the CO2levels within the space rise above the seasonal pre-set level then the system will
provide ventilation proportionally to meet the requirements of the space, by opening the
external air damper and varying the fan speed until the desired CO2 levels are reached.
If cooling is required then the system will provide the required ventilation whilst maximising the
cooling effect. If it is cooler inside than outside then the system will mix the air to minimise the
amount of air taken from outside whilst meeting the ventilation requirements. If it is cooler
outside than inside then the system will provide air from outside only.
If cooling is not required then the system will prevent the temperature from falling below a pre-
set level. In winter the PCM heat exchanger can be used to temper the air before it enters the
room. The system can also mix internal air with external air before it enters the building to
prevent any cold draughts.
8.5.5. Heat Recovery Mode:
During the cold months of the year when either the room is unoccupied or the temperature
exceed preset levels the system will recirculate internal air over the PCM heat exchanger to
charge the thermal energy store and capture this waste / excess heat.
