FEATURES AND TECHNICAL DATA
The Gitié ARAY package consists of a heat pump GAHP-AR and a
condensing boiler AY00-120.
1.1
FEATURES
1.1.1
GAHP-AR Unit features
Operation
Based on the thermodynamic water-ammonia absorption cycle
(H
2
0–NH
3
), the appliance alternatively produces hot water or
chilled water with (seasonal) switching of the hot/cold cycle, us-
ing outdoor air as a renewable energy source and natural gas (or
LPG) as primary energy.
The thermodynamic cycle takes place within a hermetically
sealed circuit, in welded construction, perfectly tight, facto-
ry-tested, which does not require any maintenance or coolant
top-ups.
The GAHP-AR unit, for heating and/or cooling systems, is able to
alternatively (not simultaneously) provide:
▶
Hot water up to 60 °C.
▶
Chilled water up to +3 °C.
Mechanical and thermo-hydraulic components
▶
Steel sealed circuit, externally treated with epoxy paint.
▶
Multigas pre-mixing burner equipped with ignition and
flame detection managed by an electronic control unit.
▶
Titanium stainless steel shell-and-tube water heat exchang-
er, externally insulated.
▶
Air exchanger with finned coil, with steel pipe and alumin-
ium fins.
▶
Inversion valve on the cooling circuit, for use of the appli-
ance in heating or cooling mode.
▶
Automatic microprocessor-controlled finned coil defrosting
valve.
▶
Variable-flow (for summer operation) microprocessor-con-
trolled helicoidal motor-fan.
▶
Standard or S silenced fan (reduction of electrical consump-
tion and reduction of sound emission).
Control and safety devices
▶
S61 electronic board with microprocessor, LCD display and
knob.
▶
Auxiliary AR11 electronic board.
▶
Circuit water flow switch.
▶
Generator limit thermostat, with manual reset.
▶
PT1000 flue gas temperature probe.
▶
Differential flue gas pressure switch on the combustion cir-
cuit.
▶
Sealed circuit safety relief valve.
▶
Bypass valve, between high and low-pressure circuits.
▶
Ionization flame control box.
▶
Double shutter electric gas valve.
▶
Antifreeze functions for hydraulic circuit.
1.1.2
AY00-120 Unit features
Operation
The AY00-120 unit is a high efficiency condensing boiler suitable
for supply hot water up to 80 °C. The appliance is provided with
an internal heat exchanger to separate internal hydraulic circuit
from system hydraulic circuit.
Mechanical and thermo-hydraulic components
▶
Premixed multigas burner with low NOx and CO emissions.
▶
Stainless steel plate heat exchanger, which also acts as a hy-
draulic separator.
▶
Automatic and manual air vent devices on the appliance in-
ternal circuit.
▶
Flue gas exhaust duct with relevant terminal, for type B53P
configuration.
▶
Condensate discharge siphon (with antifreeze protection).
Control and safety devices
▶
Electronic board with microprocessor.
▶
Automatically resettable water temperature limit thermo-
stat.
▶
Flue gas limit thermostat, for single use (thermal switch).
▶
System circuit water differential pressure switch (PD1).
▶
Appliance internal circuit water differential pressure switch
(PD2) with anti-welding function.
▶
Overpressure valve for the appliance internal circuit, set to
trip at 3 bar.
▶
Appliance internal circuit expansion tank.
▶
Ionization flame control box.
▶
Double shutter electric gas valve.
▶
Antifreeze functions for hydraulic circuit.
▶
Antifreezing thermostat for the heating element on the con-
densate siphon.
