Abstract
Methods and systems are provided for operating a dual loop heat pump system in a de-icing mode which enables the heat pump system to maintain a target rate of heat delivery to a cabin while de-icing an outside heat exchanger by leveraging waste-heat available at one or more waste-heat sources. In one example, responsive to an outside heat exchanger de-icing request and a cabin heating request, selecting a first waste-heat heat exchanger based on a temperature of the first waste-heat heat exchanger exceeding a first temperature threshold, flowing coolant to the first waste-heat heat exchanger, flowing a first portion of the coolant exiting the first waste-heat heat exchanger to a cabin heat exchanger, and flowing a second portion of the coolant exiting the first waste-heat heat exchanger to an outside heat exchanger.
