Method for controlling hot water circulation system associated with heat pump

摘要

Disclosed is a method for controlling a hot water circulation system associated with a heat pump. The present invention gives a freezing burst prevention operation function to a water-refrigerant heat-exchanger which performs heat exchange between a refrigerant and water, making it possible to remove a phenomenon that the water-refrigerant heat-exchanger installed out of the space where a user lives is frozen to be damaged.
