Air-conditioning unit capable of refrigeration and heat-production simultaneously

The utility model provides an air condition set which can cool and heat simultaneously comprising an outdoor set, a coolant distributor and an indoor set, wherein the indoor set, the coolant distributor and the indoor set compose a complete circulatory system by connecting a pipeline, the coolant distributor consists of a high gas-liquid separator, an electronic expansion valve A, an electronic expansion valve B, a four-way valve which is corresponding to the indoor set. The air condition set can achieve the purpose of cooling and heating simultaneously by controlling the flow direction of the four-way valve, further can realize cooling and heating simultaneously by controlling the distribution of the flow accurately with the temperature scope of 5 DEG C below zero to 30 DEG C. The utility model can maximize the effect of saving energy when the air condition set is in cooling and heating simultaneously.
