摘要： A system and method is provided for monitoring a system pressure to infer whether a high pressure cut out (HPCO) switch has opened disabling a heating, ventilating, and air conditioning (HVAC) compressor. A system and method are also provided for determining whether to disable the HVAC compressor based on a status of a low pressure cut out (LPCO) switch, an ambient temperature, and system mode state. The systems and methods may be used interchangeably with the appropriate adjustments to decision limits, such as where the LPCO may be monitored to infer status and the HPCO status may be directly used with temperature and system mode state.

摘要： A system and a method are provided for returning oil in a heating, ventilation, and air conditioning (HVAC) system by determining when an ambient zone temperature is equal to or less than a temperature limit and reversing a direction of refrigerant flow of the HVAC system based on the length of time. Also, a system and a method are provided for monitoring the length of operation in a first and a second heating mode and for reversing a direction of refrigerant flow based on the length of time operation occurs in the first and second heating modes. A system and a method having a first compressor, a first heating mode, a second heating mode, a defrost mode, and a controller is disclosed. The controller selectively controls initiation of the defrost mode in response to an HVAC system operating in a heating mode of operation for a predetermined amount of time.

摘要： An air handling unit has a blower configured to selectively move air from an air inlet of the air handling unit to an air outlet of the air handling unit along an airflow direction extending from the blower to the air outlet, a heat exchanger disposed within the air handling unit between the inlet and the outlet, the heat exchanger has a thermal conductor, an evaporator tube thermally conductively joined to the thermal conductor, and a subcooler tube thermally conductively joined to the thermal conductor. An expansion device provides fluid communication between the evaporator tube and the subcooler tube and a drain pan disposed within the air handling unit upstream relative to the at least one subcooler tube and positioned in a geometrical footprint of at least a portion of the drain pan as the drain pan is viewed from an upstream position in the airflow direction.
