Embodiment 1

[0017] Embodiment 1: A flat-plate sealing structure of the same well outlet and return water device, see figure 1 and figure 2 , the water outlet pipe 2 and the water return pipe (or the water return branch pipe) are simultaneously arranged in the supporting permeable pipe 5 . The outside of the water outlet pipe 2 is also sleeved with an outlet pipe sleeve 4, and the outlet pipe 3 and the outlet pipe sleeve 4 are in clearance fit. The outlet pipe 3 is used for connecting with the submersible pump, and the return pipe is used for connecting with the high-pressure water return device.

[0018] In order to achieve a better return water effect, multiple sealed return water spaces can be set up to perform return water and heat exchange through multiple channels.

[0019] The supporting permeable pipe 5 is composed of alternately distributed permeable sections 8 and supporting sections; recessed column sections 6 are respectively fixed on the inner walls of one or more supportin...

Embodiment 2

[0024] Embodiment 2: The drawings are not drawn, and the content is basically the same as that of Embodiment 1, except that the number of return water pipes is one, and the return water pipes are provided with water outlets in each return water space.

Embodiment 3

[0025] Embodiment 3: The drawings are not drawn, and the content is basically the same as that of Embodiment 1, except that the sealing ring is directly fixed on the outside of the outlet pipe, and the outlet pipe is subjected to heat insulation treatment, such as wrapping a layer of heat-insulating cotton on the outside of the outlet pipe Etc. heat insulation.

Abstract

The invention discloses a cylinder type seal structure of a water outlet and return device in the same well for a water source heat pump central air conditioner. A plurality of sunken column sections and sealing rings are respectively arranged between a supporting permeable pipe and a water outlet pipe sleeve of a water outlet pipe; a plurality of isolation layers and water return spaces are formed after butting, and a water outlet of each water return pipe is respectively positioned in each water return space. The sealing rings on the water outlet pipe sleeve and the sunken column sections on the supporting permeable pipe are utilized to form a plurality of groups of isolation layers and independent closed water return spaces, so that the water return pipes are respectively pressed into different water return spaces to achieve the purpose of multiple water return paths. Therefore, an equal amount of effluent water and returned water is realized in the same well, and fully exchanges heat with soil. The returned water does not generate new heat exchange with the effluent water reaching the initial water outlet temperature in the process that the returned water is in contact with the wall of the water outlet pipe, so that the efficiency of a water source heat pump unit can be substantially improved.

Description

technical field [0001] The invention relates to the problem of water source well recharge in the technical field of water source heat pump central air conditioners, in particular to a cylindrical sealing structure of a water source heat pump central air conditioner with well outlet and return water devices. Background technique [0002] The water source heat pump central air conditioner is a central air conditioner that uses groundwater with a constant temperature for many years as the medium. Through the heat pump unit, the water temperature is raised or lowered to achieve the purpose of cooling and heating, and to provide cold and heat sources for buildings. Because of its high energy efficiency ratio, it saves 40-60% energy compared with other traditional forms of central air conditioners, and has a remarkable effect of energy saving and consumption reduction. It is gradually favored by governments, agencies, and business units, and has also been recognized by most users. ...
