Abstract: A compressor includes an inlet and the inlet includes a flange and an impeller eye. The flange is connected to a suction line that transfers a refrigerant into the compressor via the impeller eye. The refrigerant flows into the compressor with an amount of swirl and a pressure loss. The suction line includes a geometry that includes a constantly decreasing cross-sectional area in a direction towards the compressor. The geometry of the suction line is configured to reduce the amount of swirl and the pressure loss.

Abstract: Embodiments of the present disclosure relate to a vapor compression system that includes a refrigerant loop, a compressor disposed along the refrigerant loop and configured to circulate refrigerant through the refrigerant loop, and a heat exchanger disposed along the refrigerant loop and configured to place the refrigerant in a heat exchange relationship with a cooling fluid. The heat exchanger includes a water box portion having a first length, a shell having a second length, a plurality of tubes disposed in the shell and configured to flow the cooling fluid, and a cooling fluid portion having a third length, where the water box portion and the cooling fluid portion are coupled to the shell, such that the first length, the second length, and the third length form a combined length of the heat exchanger that is substantially equal to a target length.

Abstract: An adaptive capacity constraint management system receives a measured value affected by HVAC equipment at actual operating conditions and uses the measured value to determine an operating value for a variable that affects a capacity of the HVAC equipment at the actual operating condition. The system uses the operating value to calculate a gain factor for the variable relative to design conditions and uses the calculated gain factor to determine a capacity gain for the HVAC equipment relative to the design conditions. The system applies the capacity gain to a design capacity limit for the HVAC equipment to determine a new capacity limit for the HVAC equipment at the actual operating conditions. The system may use the new capacity limit as a constraint in an optimization routine that that selects one or more devices of the HVAC equipment to satisfy a load setpoint.

Abstract: The present disclosure relates to a sensor disposed in a conduit on a suction side of a compressor, wherein the conduit is configured to convey a fluid and a controller communicatively coupled to the sensor. The controller includes a processor and a memory, the memory is configured to store instructions to be performed by the processor, and the controller is configured to receive one or more indications from the sensor of an amount of power consumed by an active sensor component, determine a presence of liquid in the fluid based at least on the one or more indications, and control a device based on the presence of liquid in the fluid.
