Special joint for ground-source heat pump system and ground-source heat pump system

Abstract

The invention relates to the technical field of ground-source heat pumps, in particular to a special joint for a ground-source heat pump system and the ground-source heat pump system. The special joint for the ground-source heat pump system comprises joint body; the joint body is arranged vertically, is hollow inside and comprises a main joint body; the main joint body comprises a first connectingport, a second connecting port and a third connecting port; the first connecting port is arranged at the upper end of the main joint body; the second connecting port is arranged on one side surface of the main joint body; the third connecting port is arranged at the lower end of the main joint body; a tip detachably connected with the first connecting port is arranged at the first connecting portand is provided with a wire hole communicating with an inner cavity of the joint body; a cable of a measuring device penetrates through the wire hole; the second connecting port is connected with a buried pipe horizontal header; and the third connecting port is connected with a buried hole heat exchanger. By the aid of the special joint, characteristic data of a fluid inside a buried pipe can bemeasured conveniently and accurately, design of the buried hole heat exchanger and stable operation of the ground-source heat pump system are effectively guaranteed, and the joint is simple in structure and simple and convenient to mount.

Description

technical field [0001] The invention relates to the technical field of ground source heat pumps, in particular to a special joint for ground source heat pump systems and the ground source heat pump system. Background technique [0002] In recent years, due to the characteristics of environmental protection, high efficiency and energy saving of the ground source heat pump system, with the encouragement and support of the government and relevant departments, the ground source heat pump system has entered a development boom. The core technology of the ground source heat pump air-conditioning system is the design and construction of the buried tube heat exchanger. Since the buried tube heat exchanger is installed underground, it is affected by the difference in soil structure and characteristics at different depths, and it is often difficult to simply calculate it according to the simplified model. If the error is too large, complete and accurate physical parameter data can only...
