Abstract: A valve system is disclosed for use with a compressor, an indoor heat exchange coil, and an outdoor heat exchange coil. The valve system may include a first reversible valve and a second reversible valve. The first reversible valve may be configured to receive heated refrigerant from the compressor. The second reversible valve may be configured to provide cooled refrigerant to the compressor. In a heating mode, the first reversible valve may be configured to provide the heated refrigerant to the indoor heat exchange coil. In the heating mode, the second reversible valve may be configured to receive the cooled refrigerant from the outdoor heat exchange coil.

Abstract: A split heating, ventilation, and air conditional system may include an outdoor unit including a compressor and an outdoor metering device. An indoor unit may be fluidically coupled to the outdoor unit. A controller may be configured to control the outdoor unit and the indoor unit based on an indoor metering status of the indoor unit. The indoor metering status may include at least one of: (i) indoor metering device on, (ii) indoor metering device off, and (iii) indoor metering device absent. In embodiments, an outdoor assembly couplable to an indoor unit of a split system may include the outdoor unit and the controller. A method for controlling a split system including an indoor unit fluidically coupled to an outdoor unit may include controlling, by a controller, based on the indoor metering status of the indoor unit, the outdoor unit and the indoor unit.

Abstract: 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.
