A vehicle heating, ventilating, and air conditioning (HVAC) system can reduce a load applied to a vehicle powertrain during certain conditions. The system can include a compressor operable based on a first target evaporator outlet (TEO) temperature map. Systems and methods can determine if an HVAC system is activated, and whether an engine water temperature meets a forced HVAC recirculation intake threshold. Responsive to determining that the engine water temperature meets the forced HVAC recirculation intake threshold, it can be determined if the engine water temperature meets a first threshold. Responsive to the recirculation mode air source being selected, determining if at least one measured vehicle condition meets predetermined criteria. Responsive to determining that the engine water temperature meets the first threshold, the compressor can be operated based on a second TEO temperature map, the second TEO temperature map including higher TEO temperatures than the first TEO temperature map.

An air temperature sensing apparatus and a system for an aircraft includes an ejector with a first air duct for receiving a first air flow from an aircraft air distribution duct, the first air duct defining a first cross-sectional area, a second air duct for receiving a second air flow from a passenger compartment of the aircraft, the second air flow merging with the first air flow downstream of the second air duct, and a restrictor connected to the first air duct defining a minimal cross-sectional area. The apparatus and system also include a temperature sensor in fluid communication with the second air flow. The minimal cross-sectional area of the restrictor is smaller than the first cross-sectional area of the first air duct to create a region of low pressure within the ejector, causing the second air flow to be suctioned over the temperature sensor.

A method for operating an electric motor-driven refrigerant compressor of a motor vehicle is provided.
