Function
•
The heat pump circuit contains the refrigerant
•
The compressor compresses the gaseous refrigerant which is heated in the
process.
•
The condenser (7) releases heat into the process air which is then blown by the
process air wheel into the drum.
•
The heat dissipation causes the refrigerant to condense.
•
The connecting capillaries cause the refrigerant to expand abruptly. As a result,
the pressure and temperature are reduced, but the coolant remains liquid.
•
The evaporator now absorbs heat from the moist process air and the coolant
becomes gaseous. The cooling of the moist warm process air causes water to
condense on the fins and then to flow into the base group.
•
The compressor now draws the gaseous coolant in again and compresses it
again.
•
The fan cools the compressor to prevent the self-locking system (OLP) from
activating.
