description The invention discloses a vapor-injected multi-connected air conditioning system. The system comprises an indoor unit, an outdoor unit, a distribution pipe, and a throttle device, wherein the outdoor unit is provided with a first electronic expansion valve capable of changing the operating state of coolant, the indoor unit is connected with the outdoor unit through the distribution pipe and the throttle device disposed on the distribution pipe of the indoor unit is used for changing the operating state of the coolant. Under the refrigerating condition, the first electronic expansion valve is fully open, while the operating state of the coolant is unchanged. The operational reliability of the vapor-injected multi-connected air conditioning system can be improved.
