Abstract: A heat pump includes a refrigerant loop. The refrigerant loop includes a compressor, a first condenser, a vapor generator having a first region and a second region, a first expansion valve, a second expansion valve, and a first evaporator. A branching point is positioned between the first condenser and the vapor generator. The branching point diverts a portion of a first heat exchange fluid circulating through the refrigerant loop to the vapor generator. The first expansion valve is positioned between the branching point and the vapor generator. An outlet vapor generator is coupled to a mid-pressure inlet port of the compressor.

Abstract: A heat pump includes a refrigerant loop. The refrigerant loop includes an accumulator having an inlet and an outlet, a compressor, a first heat exchanger, and a first coupling point. The compressor includes a low-pressure inlet and an outlet. The low-pressure inlet is downstream of the outlet of the accumulator. The first heat exchanger includes an inlet and an outlet. The first coupling point is positioned immediately downstream of the outlet of the accumulator and immediately upstream of the low-pressure inlet of the compressor. The first coupling point is immediately downstream of the outlet of the first heat exchanger such that a first heat exchange fluid circulating through the refrigerant loop is directed to the low-pressure inlet of the compressor upon exiting the outlet of the first heat exchanger.

Abstract: A vehicle HVAC system includes a compressor, a first heat exchanger for exchanging heat between the refrigerant outside air, a first check valve set, a first expansion device for decompressing a first portion of the refrigerant, a second heat exchanger for exchanging heat between the first portion of the refrigerant and a second portion of the refrigerant, a second expansion device for decompressing the second portion of the refrigerant, a second check valve set, a third heat exchanger for exchanging heat between the refrigerant and inside air, and a selector valve for switching between a heating mode and a cooling mode. The first check valve set and the second check valve set together maintain a constant flow direction through the first expansion device, the second heat exchanger, and the second expansion device in the heating mode and the cooling mode.

Abstract: A refrigerant loop of a vapor injection heat pump includes a compressor, first and second expansion valves, and first and second separator valves. The separator valves allow an entire refrigerant flow to pass therethrough or operate to separate vapor and liquid components of expanded refrigerant and inject the vapor component into a suction port of the compressor. Vapor injection occurs in both heating and cooling modes of operation and may depend upon an ambient condition (e.g., high or low ambient temperatures). An accumulator receives an output refrigerant of the heat exchangers dependent upon the mode and directs a vapor component into another suction port of the compressor. A control module controls at least the first and second expansion valves and first and second separator valves dependent upon the mode of operation which include, among others, heating, cooling, and dehumidification and re-heating.

At least one of the main compressor and the auxiliary compressor is operated based on a thermal load of the chiller.

Abstract: A vehicle includes a vapor-injection heat pump having a refrigerant loop with an evaporator configured to cool cabin air, the evaporator coupled to an electronically controllable pressure regulating valve having a fully-open position with near-zero pressure drop, and a cabin conditioning coolant loop having a heater core configured to selectively heat the cabin air. A controller is configured to control the valve to maintain temperature and pressure of the refrigerant loop above a freezing threshold to inhibit or prevent evaporator icing. The valve may be controlled to throttle flow during a parallel dehumidification mode and to fully open to minimize pressure drop during other operational modes, such as a cooling mode, heating mode, de-icing mode, and series dehumidification mode.

Abstract: A vehicle includes an interior and a controller configured to control a climate system for the interior based at least in part on data related to a departure location of the vehicle, a destination location of the vehicle, or a proximate location within a certain proximity to the vehicle, while moving to the destination location between the departure location and the destination location, or any combination of said locations. The data related to the departure location can include a temperature profile of the departure location. The temperature profile of the departure location can assume that the departure location is colder than a comfortable ambient temperature, and the controller is configured to direct heated air into the interior upon activation of the vehicle at the departure location. The data related to the departure location can include an activity profile of the departure location.
