The invention belongs to the technical field of heating ventilation air conditioners and relates to a coordinated-control synchronous-multi-cycle heat-pump heating-cooling air conditioner composite system. The system has the beneficial effects that a cooling and heating scope of a traditional air conditioning unit is broadened through design of a multi-cycle access, and cooling and heating capacities of a heat-pump heating-cooling air conditioner are enhanced comprehensively, so that an efficient ultralow-temperature heating cycle and an efficient ultrahigh-temperature cooling cycle are realized; prominent problems that an existing heat-pump heating-cooling air conditioner is high in energy consumption, small in environment-adapted temperature scope and small in application scope are solved effectively; and unification of efficient energy saving and reliable running of the system is realized. 本发明属于暖通空调技术领域，涉及一种协同控制、同步多循环热泵型冷暖空调复合系统，该系统通过设计多循环通路拓宽了传统空调机组制冷、制热的范围，全面提升热泵冷暖空调系统制冷、制热能力，从而实现高效的超低温制热循环和超高温制冷循环，有效解决了
