Assignee:

Trane International Inc. - Piscataway NJ

International Classification:

F04B 49/00
F25B 49/00

US Classification:

417 38, 417 442, 622283, 622281

Abstract:

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.

International Classification:

G06F 19/00

US Classification:

700276, 417 12

Abstract:

A system and a method are provided for powering up a heating, ventilation, and air conditioning (HVAC) system and operating a sump heater for a compressor for a first predetermined period of time in response to the HVAC system being powered up. A heating, ventilation, and air conditioning system and a method for controlling the system are provided. The HVAC system includes a compressor, a sump heater associated with the compressor, and a controller configured to control the compressor and the sump heater so that the sump heater is not operated while the compressor is operated.

International Classification:

F25B 13/00
F25D 21/06

US Classification:

623241, 62155

Abstract:

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.

Assignee:

TRANE INTERNATIONAL INC. - Piscataway NJ

International Classification:

F25D 17/06
F28F 1/36

US Classification:

62419, 165184

Abstract:

An air handling unit has a cabinet forming a duct, a mixed-flow blower assembly configured to provide airflow through the duct, and a refrigeration coil assembly disposed within the cabinet and downstream of the mixed-flow blower assembly. Another air handling unit has a cabinet forming a duct having a generally downstream direction and a blower assembly to provide airflow through the duct. The blower assembly may have an axis of rotation generally parallel to the downstream direction and the blower assembly may be configured to primarily expel air in a direction that has a directional component that extends radially away from the axis of rotation.

International Classification:

G05D 23/00
F25B 41/04

US Classification:

165287, 62225

Abstract:

A method of reducing a cyclical loss coefficient of an HVAC system efficiency rating of an HVAC system includes operating the HVAC system using a recorded electronic expansion valve position of an electronic expansion valve of the HVAC system, discontinuing operation of the HVAC system, and resuming operation of the HVAC system using an electronic expansion valve position that allows greater refrigerant mass flow through the expansion valve as compared to the recorded electronic expansion valve position.

Abstract:

In at least some embodiments, a hybrid heating system includes a heat pump and an auxiliary furnace. The system also includes a controller coupled to the heat pump and the auxiliary furnace. The controller, in response to receiving a heat request, selects either the heat pump or the auxiliary furnace based on an economic balance point algorithm.
