[0039] In summary, the utility model is a variable frequency integrated heat pump unit that improves temperature regulation efficiency through the cooperation between the outdoor unit 10, the fresh air unit 20, the hydraulic module 30 and the heating and cooling radiation system 40. The outdoor unit 10 uses a variable frequency heat pump system to cooperate with the fresh air unit 20 to cool or heat the air flow, and uses another variable frequency heat pump system to cooperate with the hydraulic module 30 to cool or heat the water flow. The hydraulic module 30 uses a third pipe system 53 to transport cold water or hot water to the heating and cooling radiation system 40, so that the operation of the fresh air unit 20 and the heating and cooling radiation system 40 can efficiently regulate the temperature.
