-          Commissioning and settings of a refrigerating installation

-          Standard operation procedure to recover and load the refrigerant (requires additional tools)

-          Setting of the control components (pressure control valve)

-          Maintenance operations on a refrigeration installation

Description

The bench HFF 290 is designed to train the learners in the handling of refrigerants R290. The installation is based on a refrigerating cycle operating with R290. It comprises the main components of a positive installation, a compressor, a condenser, a receiver, a solenoid control valve, an expansion valve, an evaporator and a suction line accumulator. Service valves and fittings Schrader type allow the learners to connect a manifold for the load operations, recovery operation and verification operation.

The cold chamber is simulated by a cabinet. The cabinet door is equipped with an enthalpy diagram R290 with erasable surface (format A3). A thermostatic control box will control the operation of the solenoid valve (pump down control). Two switches located on the box are used to stop the operation of the solenoid valve and of the condenser (this facilitates adjustment of the pressure switches).

 

The robust design of this equipment makes it perfectly suited for use in schools. Its anodized aluminum structure on wheels makes it extremely robust as well as a great flexibility of integration into your premises. In the lower part, the bench comprises a storage area equipped with two doors with key locking (storage of tooling).
