The embodiment of the invention discloses an air-conditioning system for controlling the air supply humidity of a refrigeration area and/or a luggage area, which comprises a box body, an air inlet, an air outlet, an air inlet and an air outlet, a filter, a central refrigerant water coil pipe, a low-temperature saline water coil pipe, a central heating medium water coil pipe and an air feeder are sequentially arranged in the box body in the direction from the air return opening to the air outlet, a streaming medium in the low-temperature saline water coil pipe is saline water return water of the refrigeration system, and a saline water frequency conversion circulating pump is arranged on a water inlet pipe of the low-temperature saline water coil pipe. A first variable-frequency electric control two-way valve and an electric control three-way valve are sequentially arranged on a water outlet pipe of the low-temperature saline water coil pipe, and a bypass port of the electric control three-way valve is communicated with a water inlet of the saline water variable-frequency circulating pump through a bypass pipe; the brine frequency conversion circulating pump simultaneously sucks part of brine discharged by the water outlet pipe and part of brine return water passing through the refrigeration system, the temperature of the brine return water is not greater than zero DEG C, and the temperature of the brine at the water outlet of the brine frequency conversion circulating pump is not less than zero DEG C.

    本发明实施例公开了一种控制冷藏区和/或行李区送风湿度的空调系统,包括:箱体,其一端设有回风口,另一端设有出风口;在箱体内沿回风口至出风口方向,依次设置有滤器、中央冷媒水盘管、低温盐水盘管、中央热媒水盘管和送风机,其中,低温盐水盘管中的流媒体为冷藏系统的盐水回水,低温盐水盘管的进水管上设有盐水变频循环泵,低温盐水盘管的出水管上依次设有第一变频电控两通阀和电控三通阀,且电控三通阀的一旁通口通过旁通管与盐水变频循环泵的入水口连通,以使的盐水变频循环泵同时吸入部分经由出水管排出的盐水和部分经由冷藏系统的盐水回水,盐水回水的温度不大于零摄氏度,盐水变频循环泵的出水口的盐水温度不小于零摄氏度。
