Abstract: An air conditioning system includes an indoor electronic expansion valve, and at least one liquid phase branch pipe. Each liquid phase branch pipe includes a first flow pipe and a second flow pipe. An end of the second flow pipe is communicated to an end of the first flow pipe, and another end of the second flow pipe is communicated to the indoor electronic expansion valve. The liquid phase branch pipe is configured to branch or converge a refrigerant flowing through the liquid phase branch pipe. The first flow pipe includes at least one mixing member, each mixing member has a plurality of first through holes, and the plurality of first through holes are used to communicate two ends of the first flow pipe.

Abstract: An air conditioner includes an indoor unit, an outdoor unit, and a controller. The outdoor unit is connected to the indoor unit, and the outdoor unit includes a housing, a compressor, a four-way valve, an outdoor fan, a separating device, and a plurality of outdoor heat exchangers arranged in parallel.

Abstract: An air source heat pump system includes at least one heat pump sub-system and at least one water tank. Each heat pump sub-system includes a refrigerant circulation path and a water supply circulation path. The refrigeration circulation path includes a compressor, a first heat exchanger, a first throttling device, and an evaporator that are sequentially connected to one another. The water supply circulation path includes a first supply pipe, a second supply pipe, a return pipe, and a waterway control valve. The first supply pipe and the second supply pipe are each communicated with an end of the first heat exchanger through the waterway control valve, and the return pipe is communicated with another end of the first heat exchanger. The return pipe is communicated with a water inlet of a corresponding water tank, and the second supply pipe is communicated with a water outlet of the corresponding water tank.

Abstract: An air conditioner includes an outdoor unit, a plurality of indoor units, and a controller. The outdoor unit includes a first throttling device. The indoor unit includes a second throttling device. The controller is configured to: regulate an opening degree of the first throttling device, so that a first supercooling temperature is within a first supercooling temperature range in a case where the air conditioner is in a cooling mode; regulate opening degrees of a plurality of second throttling devices in a case where the air conditioner is in a heating mode, so that a plurality of second supercooling temperatures are each within a second supercooling temperature range, and an absolute value of a difference between each of the plurality of second supercooling temperatures and an average value of the plurality of second supercooling temperatures is less than or equal to a first threshold.
