CLIMAVENETA i-ACCURATE i-AX Installation Manual - User And Maintenance page 5

ELECTRICAL PANEL
Built and wired in compliance with the IEC 204-1/EN60204-1
standards, complete with contactor and overload protection for
the compressors and fans, disconnecting switch with door inter-
lock safety device.
CONTROL
The microprocessor, by managing the compressor activation
times, controls the cooling capacity and the operating alarms, with
the possibility of connection to supervisor systems.
AIR FLOW SENSOR
Activates an alarm in the event of insufficient air flow.
ELECTRIC POST -HEATING (versions R or T)
Finned aluminium heaters complete with safety thermostat to cut
off power and activate an alarm in the event of overheating.
The electric heaters are used to:
- Heat the air so as to reach the set point
- Reheat the air during dehumidification operation, bringing the
air temperature back to the set point
HEATING WITH HOT WATER COIL
The coil, complete with water circuit air vent valve, is located
downstream of the evaporator coil.
The option is supplied complete with modulating 3-way valve with
servomotor, managed by the EVOLUTION controller.
Finned coil heat exchanger made from copper tubes expanded
mechanically onto aluminium fins with high heat exchange area.
The hot water coil can either be an alternative to or in combina-
tion with the electric heaters, and is used to:
- Heat the air so as to reach the set point.
- Reheat the air during dehumidification operation, bringing the
air temperature back to the set point.
REHEATING WITH HOT GAS COIL
Available as an alternative to the hot water coil, this is placed
downstream of the evaporator coil, and is used during dehumidifi-
cation operation to reheat the air using some of the heat
exchanged at the condenser, bringing the temperature back to the
set point with CONSIDERABLE energy savings.
The option includes a finned coil heat exchanger made from cop-
per tubes expanded mechanically onto aluminium fins with high
heat exchange area, and an on/off valve managed by the EVOLU-
TION controller, which activates the reheating circuit.
The hot gas coil can be used in combination with the electric
heaters.
IMMERSED ELECTRODE HUMIDIFIER (versions H or T)
Modulating steam production and automatic control of the salt
concentration in the boiler to allow the use of untreated water.
MICROPROCESSOR CONTROL SYSTEM
For the control of the ambient parameters and the management
of the unit monitoring and control functions (compliant with EEC
directive 89/336).
DIRECT EXPANSION MODELS
HERMETIC SCROLL COMPRESSOR with high energy efficiency
and low noise level, and inbuilt thermal overload protection.
REFRIGERANT CIRCUIT including:
- liquid receiver;
- dewatering filter and flow indicator;
- electronic expansion valve;
- oil separator (in the circuit with inverter-driven compressor)
- external connections with cocks;
- low and high pressure switches (with manual reset).
WATER CONDENSER (water-cooled models) with braze welded
stainless steel plates.
