Abstract: Systems and methods are disclosed herein that include controlling operation of a heating, ventilation, and/or air conditioning (HVAC) system that utilizes information from a plurality of temperature sensors to monitor, verify, determine, and/or discover whether a temperature sensor is properly located in proximity to a dome of a compressor of the HVAC system. When the HVAC system determines that the temperature sensor associated with the dome of the compressor is not properly located, the HVAC system may initiate a shutdown of the compressor and/or other components of the HVAC system, generate a signal, present a message, and/or otherwise provide a notification of the improper temperature sensor placement, and/or reduce a runtime of the compressor, operate the compressor at a lower speed, reduce a power consumption of the compressor, and/or otherwise control the compressor and/or associated components to effectuate a reduced compressor dome temperature.

Abstract: Example embodiments of the present disclosure relate to a climate control system and methods for controlling the system. Some embodiments include a system that includes a refrigerant circuit with both a main circuit and a bypass circuit, where the main circuit directs the refrigerant fluid from a compressor to a first heat exchanger, a metering device, a second heat exchanger, and an accumulator, and the bypass circuit selectively directs a portion of the refrigerant fluid to a third heat exchanger. The bypass circuit includes a bypass control valve and a bypass metering device, the bypass control valve controlling the flow of the portion of the refrigerant fluid to be directed to the third heat exchanger, and the bypass metering device lowering the temperature of the portion of the refrigerant fluid before the portion of the refrigerant fluid enters the third heat exchanger. The third heat exchanger may be located proximate the accumulator.

Abstract: Embodiments relate generally to subcooling control of a heating, ventilation, and air conditioning (HVAC) system. An HVAC system may include a first electronic expansion valve (EEV) fluidly coupled to an indoor coil, wherein the first EEV is adjacent to the indoor coil. The HVAC system may also include a second EEV fluidly coupled to an outdoor coil, wherein the second EEV is adjacent to the outdoor coil. A system controller may be configured to control the first and second EEVs to control a flow of refrigerant to control subcooling (SC) produced by the HVAC system. The second EEV remains open during a cooling mode, and the first EEV modulates during the cooling mode. The second EEV modulates during a heating mode, and the first EEV remains open during the heating mode.

Abstract: A two temperature electronic expansion valve control for variable speed compressors that utilizes a correlation between airflow percentage and heat exchanger pressure drop to control the operation of an expansion valve. An indoor airflow percentage request may be communicated from an outdoor controller to an air handler controller. Using a correlation between airflow percentage and pressure drop across the heat exchanger, the airflow percentage may be used in predicting an outlet pressure of refrigerant exhausted from the heat exchanger. The predicted pressure drop may be used in determining a saturated temperature for the exhausted refrigerant. The determined saturated temperature may be compared to a sensed temperature of the refrigerant at the outlet of the heat exchanger to determine a superheat value, which is compared to a reference superheat value in determining the degree to open or close the expansion valve.

Abstract: Examples of the present disclosure relate to systems and methods for controlling the positioning of a modulating valve of a heat pump based on a discharge temperature setpoint of a compressor during periods of low ambient outdoor temperatures. A supervisory switching controller may determine that the climate control system should use a discharge temperature controller or a superheat controller to control the modulating valve. Upon detection of ambient outdoor temperatures below a minimum threshold and the detection of discharge temperatures of a compressor above a maximum threshold a discharge temperature controller may control the modulating valve. The discharge temperature controller may control the positioning of the modulating valve based on a discharge temperature setpoint and a map-based controller. The map-based controller may map a calculated discharge temperature error to a position of the modulating valve as a function of a calculated superheat value and a measured suction pressure.
