摘要： When the temperatures of outdoor heat exchangers 23a and 23b detected by outdoor heat exchanger temperature sensors 57a and 57b become equal to or higher than 5 degrees C. and the sucking superheating degrees of compressors 21a and 21b become equal to or lower than 0 degrees C. while an air conditioning apparatus 1 is performing the reverse defrosting operation, the reverse defrosting operation is stopped and the heating dominant operation is resumed. At this time, the total operating times of the compressors 21a and 21b are reset. The sucking superheating degrees of the compressors 21a and 21b are obtained by subtracting the low pressure saturation temperatures calculated from the sucking pressures of the compressors 21a and 21b, from the temperatures of the refrigerants sucked into the compressors 21a and 21b which temperatures are detected by the sucking temperature sensors 54a and 54b.

摘要： A system and method for dual compressor modulation by controlling a flow of refrigerant in a reversing valve. A method includes receiving, by a control board, a command for operating a reversing valve in different modes. The reversing valve includes a first tube, a second tube, a third tube, a fourth tube and a fifth tube. The method includes determining a position for operating the reversing valve in a first position or a second position in a first mode and in a third position or a fourth position in a second mode. The method includes controlling a flow of refrigerant based on the command and the position by connecting the fourth tube with a first compressor in the first/third position and connecting the fifth tube with a second compressor in the second/fourth position.

摘要： A vapor compression system (20; 120; 220; 320) has: first (22A; 122A; 222A) and second (22B; 122B; 222B) compressors; first (40) and second (46) heat exchangers; and one or more expansion devices (52; 52A, 52B). Means (32A, 32B; 32A, 32B, 126A, 126B; 32A, 32B, 232A, 232B) are provided for switching the system between operation in first and second modes using the respective first and second compressors. In the first mode: the first compressor compresses refrigerant; the compressed refrigerant is cooled in the first heat exchanger; the cooled refrigerant is expanded in at least one of the one or more expansion devices; and the expanded refrigerant absorbs heat in the second heat exchanger. In the second mode: the second compressor compresses refrigerant; the compressed refrigerant is cooled in the second heat exchanger; the cooled refrigerant is expanded in at least one of the one or more expansion devices; and the expanded refrigerant absorbs heat in the first heat exchanger.

摘要： A heat pump system includes a refrigerant circuit that has a compressor, a first heat exchanger, a second heat exchanger, a reheat heat exchanger, a modulating valve, and a reversing valve. The reversing valve is configured to transition between a first configuration to direct refrigerant from the compressor toward the modulating valve and a second configuration to direct the refrigerant from the compressor toward the first heat exchanger. The heat pump system also includes control circuitry configured to concurrently maintain the reversing valve in the first configuration and adjust a position of the modulating valve to direct a first portion of the refrigerant from the modulating valve to the second heat exchanger and a second portion of the refrigerant from the modulating valve to the reheat heat exchanger based on an operating mode of the heat pump system.

摘要： In certain embodiments, a controller turns a heat pump system on in heating mode or cooling mode and determines a position for the heat pump system's reversing valve based on an O/B setting. The O/B setting indicates to configure the reversing valve in a first position that causes refrigerant to flow in a first direction when in heating mode and in a second position that causes the refrigerant to flow in a second, opposite direction when in cooling mode. The controller determines whether to maintain or reverse the O/B setting. If the heat pump system heats while in the heating mode or cools while in the cooling mode, the O/B setting is maintained. If the heat pump system cools while in the heating mode or heats while in the cooling mode, the O/B setting is reversed.
