CAT NO: DIDACTICNLE-Export-104006
Heat Pump With Pump Down Control- Engineering Lab Training Systems.
Technical Description
This benchtop unit comprises
components that are used in industrial heat pumps. All relevant measured
values are displayed. The energy supplied to the compressor motor can
be read on a kWh meter. A "pumpdown" circuit is included in the system.
After the evaporator outlet temperature is reached a solenoid valve
closes the inlet side to the expansion valve. The compressor continues
to run and fill the collector with refrigerant until the high pressure
cut-out activates. An environmentally friendly refrigerant is used.
A supply of cooling water is required.
