Disclosed are a heat pump system comprising a joint heat storage tank on a heat source side and a control method thereof. The heat pump system comprising a joint heat storage tank on a heat source side comprises: a plurality of heat pumps each comprising a compressor, a heat source-side heat exchanger, and a user-side heat exchanger, and individually providing cooling and heating for each user; and a plurality of geothermal heat exchange members to individually exchange heat with the heat source-side heat exchangers of the heat pumps. Heat exchange pipes buried in the ground of the geothermal heat exchange members are alternately arranged to allow the geothermal heat exchange members to exchange heat with each other via the ground. According to the heat pump system comprising a joint heat storage tank on a heat source side and the control method thereof, each heat pump and a joint heat storage tank on a heat source side can individually exchange heat to store waste heat discarded by any one heat pump among the heat pumps in the joint heat storage tank on the heat source side and then reuse the waste heat in another heat pump among the heat pumps for cooling and heating if the heat pumps are in different operation modes (e.g., one is in a cooling operation mode and another is in a heating operation mode). The dependence of the overall hat pump system on a heat source can be reduced. The joint heat storage tank on the heat source side can perform a function of a type of a buffer to easily satisfy an optimal temperature condition for operating the heat pumps at all times. |
