Problems solved by technology

The heat exchange tubes of the above-mentioned structures all have certain disadvantages, that is, the heat exchange tube has a small diameter, the contact area with the surrounding soil or filling material is small, the heat exchange efficiency is low, and the flow resistance of the heat exchange medium in the tube is relatively large. Will affect the efficiency of the heat pump unit

Embodiment Construction

[0015] The preferred embodiments of the present invention will be described in detail below with reference to the drawings.

[0016] Such as figure 1 , 2 As shown, the double-pipe heat exchange tube includes an inner tube 4 and an outer tube 3. The inner tube 4 is located in the outer tube 3, and the upper end of the outer tube 3 is connected to the medium inlet 6 through a reducing tee 5. The outer tube The lower end of 3 is sealed by a sealing element 8, the upper end of the inner tube 4 is connected with the medium outlet 7, and the lower end of the inner tube 4 is open. The outer tube 3 can be formed by connecting a plurality of short tubes with connectors 9. The outer tube 3 has a diameter of 60mm-150mm, and the inner tube 4 has a diameter of 25mm-40mm. The outer tube and the inner tube are both HDPE tubes.

[0017] When the tube-in-tube heat exchange tube is used, firstly open a heat exchange hole 1 on the ground, then insert the tube-in-tube heat exchange tube into the heat...

Abstract

The invention discloses a casing type heat exchange tube, which comprises an inner tube and an outer tube, the inner tube is located in the outer tube, the upper end of the outer tube is connected with the medium inlet, the lower end of the outer tube is sealed, the upper end of the inner tube is connected with the medium The outlet is connected, and the lower end of the inner pipe is open. The sleeve-type heat exchange tube has the following advantages: 1) It increases the contact area with the surrounding filler or soil; 2) The flow velocity of the heat exchange medium in the outer tube is reduced, which increases the heat exchange time of the heat exchange medium; The heat exchange medium conducts heat exchange downwards by its own weight, and the flow distance of the heat exchange medium in the tube is shortened.

Description

Technical field [0001] The invention relates to a ground source heat pump air conditioner, in particular to a heat exchange tube used in a ground source heat pump air conditioner. Background technique [0002] The ground source heat pump air conditioner is a new type of energy-saving and environmentally friendly air conditioner, which can make full use of the huge energy stored in the soil and lakes, recycle it, and realize heating and cooling of buildings with low operating costs. The cold and heat source of this ground-source heat pump air conditioner adopts a buried-tube ground-source heat pump system that is flexible in installation and easy to control. The buried-tube ground-source heat pump system embeds the heat exchange tubes in the ground, and is buried in the soil through the heat exchange medium. The circulating flow between the heat exchange tube and the heat pump unit realizes the heat exchange between the heat pump unit and the ground soil. [0003] At present, high-...
