Abstract
A vapor compression heat pump (VCHP) system for an electrified vehicle and a method for de-icing the VCHP system is provided. The electrified vehicle may include a vehicle cabin, the VCHP system, and a controller. The VCHP system may be in thermal communication with the cabin and include an outside heat exchanger and a compressor. The controller may be configured to, in response to detection of a predefined ice condition associated with the outside heat exchanger, output commands to adjust a speed of the compressor to influence a temperature of refrigerant flowing through the compressor such that the refrigerant carries an amount of heat sufficient to eliminate the predefined ice condition within a preselected time period. The predefined ice condition may be a condition in which the heat exchanger has accumulated ice or is likely to accumulate ice.
