Outdoor HVAC unit

Disclosed herein are air conditioning systems including a refrigerant line configured to transport a refrigerant; a compressor in fluid communication with the suction line; and a controller in communication with a sensor configured to measure a characteristic of the refrigerant line. The compressor can be configured to move the refrigerant through the refrigerant line, and the refrigerant can have a first temperature at the outlet of the compressor. The controller can be configured to receive sensor data from the sensor indicating a current value associated with the characteristic of the refrigerant line; determine, based at least partially on the sensor data, that the characteristic of the refrigerant line is above a predetermined threshold; and output instructions for the compressor to perform one or more corrective actions.

Systems and methods for humidity control in an air conditioning system

A liquid slug protector device for air conditioning and heat pump systems includes a housing having an inlet port, an outlet port, and a cavity. The device further includes a piston disposed in the cavity. The piston has an inflow channel. The device also includes a backing structure disposed in the cavity. The backing structure has an outflow channel, where a first refrigerant flow path from the inlet port to the outlet port includes the inflow channel and the outflow channel. The device further includes a peripheral channel that is at least partially bound by the piston. A second refrigerant flow path from the inlet port to the outlet port includes the peripheral channel and the outflow channel. The second refrigerant flow path is closed when the piston abuts against the backing structure.

Compressor protection against liquid slug

A pressure spike prevention assembly for use in a heat pump system includes a thermostatic expansion valve that includes a first port and a second port. The first port is designed to be fluidly coupled to an indoor coil, and the second port is designed to be coupled to an outdoor coil. The pressure spike prevention assembly further includes a multi-way valve that includes an inlet port, an output port, and a liquid line port. The inlet port is fluidly coupled to the first port. The output port is fluidly in communication with the second port. The liquid line port is configured to be fluidly coupled to a charge compensator of the heat pump system via a liquid line of the heat pump system.
