WORKING LOGIC    REFRIGERANT CIRCUIT
Components for each refrigerant circuit:
 
TRIPACK
The TRIPACK is a water cooled, heat pump liquid chiller for the production of chilled water, hot water and hot domestic hot water (multifunction). In working condition 2, the production of chilled water and domestic hot water is simultaneous. In working condition n.4, the unit gives priority to the domestic hot water production. Only when this priority is satisfied the system starts automatically to produce hot water for heating.
 
Reversing valve for refrigeration cycle inversion.
Electronic expansion valve. The valve allows high performance and system efficiency thanks to a timely and accurate response to changes in temperature and pressure.
The expansion valve is equipped with energy reserve to allow the closure of the valve in the event of lack of power supply.
Sight glass.
Filter dryer on liquid line.
Liquid receiver with service valve and safety valve.
Service valves on liquid line and gas discharge.
Safety valve on low pressure side.
Pressure transducers with indication, control and protection functions, on low and high refrigerant pressure.
High pressure safety switch with manual reset.
Oil drainage and oil recovery systems.
Refrigerant circuit with copper tubing with anticondensate insulation of the suction line.
Plastic capillary hoses for pressure sensors connection.
R410A refrigerant charge.
