The invention discloses an energy storage type heat pump device which comprises a pipe and a heat pump assembly conducting heat exchange with the pipe. A liquid medium circulates in the pipe, and an energy storage part is communicated to an outlet of the pipe and is communicated with an indoor heat exchange part; the heat pump assembly comprises a first part and a second part which are arranged in a spaced manner; and the temperature of the liquid medium is increased or decreased at the first time through the first part, and the temperature of the liquid medium is increased or decreased at the second time through the second part. By means of the energy storage type heat pump device, it is expected that in the long-term using process, only a small amount of electric energy is needed for driving the device to run, the electricity using amount is small, economical burdens of users are effectively reduced, environment pollution is avoided, two-time temperature decrease or increase is carried out on the liquid media, the refrigeration or heating efficiency is effectively improved, and the using requirement of users is further met.
