Expansion valve assembly, two-way throttle system and air conditioner

The invention provides an expansion valve assembly, a two-way throttle system and an air conditioner. The expansion valve assembly comprises a first one-way valve, a second one-way valve, a heating expansion valve, a fourth one-way valve, a third one-way valve and a cooling expansion valve, which are connected in series. Through the adoption of the scheme, the independent selection and the independent operation of the heating expansion valve and the cooling expansion valve are realized, and when the difference between required cooling capacity and required heating capacity is big, more matchedcooling expansion valves and heating expansion valves are selected for heating and cooling operation modes, so that more accurate adjustment of cooling and heating is realized. 本发明提供了一种膨胀阀组件、双向节流系统及空调器，所述膨胀阀组件包括：串联的第一单向阀、第二单向阀、制热膨胀阀、第四单向阀、第三单向阀和制冷膨胀阀，通过本方案实现制热膨胀阀、制冷膨胀阀独立选型、独立运行，当所需制冷量和制热量差别较大时，可针对制冷和制热运行模式选择更加匹配的制冷膨胀阀和制热膨胀阀，从而实现制冷制热的更精准调节。
