Energy-saving control device of ground source heat pump

The utility model provides an energy-saving control device of a ground source heat pump, which comprises a ground buried pipe water supply pipe, a ground buried pipe water return pipe, heat pump equipment, a tap water inlet pipe, a tap water outlet pipe and a buffer water tank. A water return pipe of a grounding buried pipe connected with the heat pump equipment at the farthest end is connected with a buffer water tank through a water replenishing pipe, so that liquid flow supply in the buffer water tank is further supplemented, heat in a water return pipeline is also subjected to heat exchange with water inlet liquid flow in the buffer water tank, and the heat supply pressure is increased; and therefore, the water supply capacity of the tail end ground source heat pump equipment is improved, and energy-saving control over the ground source heat pump is achieved. 本实用新型提出一种地源热泵的节能控制装置，接地埋管供水管、接地埋管回水管、热泵设备、自来水进管、自来水出管、缓冲水箱，通过增设的缓冲水箱自来水进行引入并输出并经由接地埋管供水管输送至最远端的热泵设备中，以补充对最远端的热泵设备的供水液流和供水压力，最远端的热泵设备的连接的接地埋管回水管通过补水管
