    摘要： The present invention relates to a multi-split central air conditioning system for simultaneous cooling and heating, comprising a condensation module, a plurality of indoor fan coil units, a high-pressure circulation tube, a medium-pressure circulation tube, a low-pressure circulation tube, and an evaporation module. The indoor fan coil units are connected to the high-pressure circulation tube by means of a first branch tube, to the low-pressure circulation tube by means of a second branch tube, and to the medium-pressure circulation tube by means of a third branch tube, and a solenoid valve is provided on each of the first branch tube and the second branch tube. The beneficial effects are: when heating a local area in the summer and cooling a local room in the winter, refrigerant is circulated by means of solenoid valve switching and a medium-pressure circulation tube such that the multi-split central air conditioning system has multiple working modes (independent cooling/independent heating/simultaneous partial cooling and partial heating), thereby improving the diversity of the overall operation conditions of the air conditioning system without adding a complex refrigerant switching piping. The condensation module and the evaporation module can also be used as a balancer of the system to ensure efficient and stable operation of the system.

    摘要： A method is provided for the controlled routing of hydronic flow within a climate control system. The method includes determining a condition type request for a plurality of area zones corresponding to a particular thermal zone. The method further includes determining a supply temperature type associated with at least a supply line of a primary supply loop and a supply line of a secondary supply loop. The supply temperature type is indicative of a thermal transport fluid temperature within the respective supply line. The method further includes providing an actuation signal set to a valve assembly. The actuation signal set is configured to describe a position for each value of the valve assembly and the position for each valve is based on the conditioning type request and the determined supply temperature types.

    摘要： When cooling operation or heating operation starts in a state where a flow rate control mechanism is closed after cooling operation or heating operation stops, it takes time until the flow rate control mechanism has an appropriate opening degree and operation efficiency deteriorates. An air conditioner includes an indoor unit, an outdoor unit, an outdoor expansion valve, an indoor expansion valve, and a control unit. The control unit executes first control and second control. The first control includes stopping cooling operation or heating operation if a first condition is satisfied during cooling operation or heating operation, and then starting cooling operation or heating operation if a second condition is satisfied. The first condition indicates that a heat load in a target space is low. The second condition relates to the heat load in the target space. The second control includes setting opening degrees of the outdoor expansion valve and the indoor expansion valve upon a start of cooling operation or heating operation according to the first control to be larger than opening degrees upon satisfaction of the first condition.

    摘要： Disclosed are a method and device for controlling an air conditioner. The air conditioner comprises an outdoor heat exchanger, an indoor heat exchanger, a heat storage heat exchanger, a compressor, a four-way valve assembly, and a throttling assembly, wherein the outdoor heat exchanger is connected to the indoor heat exchanger by means of a first pipeline and a bypass, the outdoor heat exchanger is connected to the compressor by means of a second pipeline, the indoor heat exchanger is connected to the compressor by means of a third pipeline, the heat storage heat exchanger is arranged on the bypass, the throttling assembly is arranged on the bypass, the four-way valve assembly comprises a first four-way valve and a second four-way valve, the first four-way valve is arranged on the second pipeline, and the second four-way valve is arranged on the third pipeline. The method comprises: identifying an operation mode of the air conditioner; if the operation mode is a heating mode, controlling the first four-way valve and the second four-way valve to be powered on; and if the operation mode is a defrosting mode, controlling the first four-way valve to be powered off and the second four-way valve to be powered on. Heat is absorbed from the heat storage heat exchanger for defrosting of the outdoor heat exchanger, thereby improving the comfort level of the air conditioner and user experience.
