Heat pump

摘要

The head pump comprises a two-stage condenser (28), where the primary stage (28a) and the secondary stage (28b) are formed on a plate heat exchanger (18) through which water flows in counter flow. The plate heat exchanger of the secondary stage is lockable for direct heat transition on brine of water at a solar collector (10). A connection between the solar collector and the plate heat exchanger of the secondary stage is controlled by a manifold valve.
