Zusammenfassung:The utility model discloses a pre-adjusting type direct-heating heat pump system, which belongs to the technical field of water temperature adjustment of heat pump water heaters, aims to solve the technical problem of water temperature adjustment in the prior art, and comprises a heat exchanger and a compressor, the heat exchanger is provided with a water inlet pipeline and a water outlet pipeline, and the heat exchanger is communicated with the compressor. A temperature detection head is arranged at the water inlet, a constant-temperature adjusting valve is arranged on a water outlet pipeline of the heat exchanger, the constant-temperature adjusting valve is communicated with a water inlet pipeline through a connecting pipeline, and the constant-temperature adjusting valve is used for controlling the mixing proportion of cold water and hot water of the water inlet pipeline. The temperature detection head is arranged on the water inlet pipeline, temperature adjustment is obviously predictable, the cold and ho
