摘要： Methods of controlling a cooling unit and embodiments of a cooling unit are disclosed. A method of improving efficiency of the cooling unit includes detecting a degree of opening of a hot gas bypass valve configured to divert a portion of coolant from a compressor to a heat exchanger of the cooling unit, and adjusting a condenser discharge pressure based on the detected degree of opening. Aspects may increase cooling efficiency at partial cooling requirements. Fluctuations in refrigerant pressure at low cooling capacities and condenser medium inlet temperature may be avoided. Minimum condenser water inlet temperature for a water-cooled cooling unit may also be reduced.

摘要： 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.
