3 Description
3.1 General description
The ALEZIO heat pump comprises:
4 A reversible outside module for energy production in hot or cold
mode.
4 An inside module with a control panel to handle the thermal
exchange between the R410A fluid and the hydraulic circuit.
The two units are connected by means of refrigeration and electrical
connections.
The inside module handles domestic hot water production.
The system offers the following advantages:
4 The heating circuit is housed in the insulated volume within the
home. There is no danger of the pipes freezing.
4 Thanks to the DC inverter system, the heat pump modulates its
output to adapt to the needs of the home.
4 The control panel uses the outside temperature sensor to adjust
the temperature of the heating circuit according to the outside
temperature.
4 The steel tank is lined with food quality standard enamel vitrified
at 850°C, which protects the tank from corrosion.
4 The coil-shaped heat exchanger welded into the tank is made of
smooth piping, its external surface, which comes into contact with
drinking water, being enamelled.
4 The appliance is insulated by CFC-free polyurethane foam, which
reduces heat losses to a minimum.
4 The outside casing is made of painted steel sheeting.
4 The tank is protected against corrosion by a magnesium anode.
