The objective of the present invention is to provide a hybrid heat pump boiler system capable of suppressing dew condensation of an outdoor unit by preventing a temperature decrease of a coolant collected to a compressor, and at the same time capable of improving performance of a heat pump by stimulating vaporization of the coolant. To realize this, the hybrid heat pump boiler system of the present invention comprises: the outdoor unit (100) and an indoor unit (200) constituting the heat pump; a heat accumulation part (300) to collect and accumulate heat of condensation of the coolant circulating in the heat pump; and a boiler (400) to heat heating water and hot water using heat accumulated in the heat accumulation part (300) and combustion heat of a burner. The outdoor unit (100) includes a compressor (110), a four-way valve (120), a receive tank (140), an expansion valve (150), an outdoor heat exchanger (170), and an accumulator (180). The indoor unit (200) includes an indoor heat exchanger (210) and an expansion valve (220). The heat accumulation part (300) includes a heat accumulation heat exchanger (310) and a tank (320). The boiler (400) includes a first heat exchanger (410) to heat the heating water absorbing heat via the water tank (320) by combustion of the burner, and a second heat exchanger (420) to exchange heat of the heating water and the hot water passing through the first heat exchanger (410). The outdoor unit (100) comprises a coolant heat delivery part (130) which delivers heat of the coolant discharged from the compressor (110) to the coolant collected to the compressor (110). |
