Embodiment 1

[0023] Example 1: The first water source heat pump central air-conditioning hose type same well water outlet and return device, see figure 1 , at the wellhead of the same water source well, the well cover 1 can be sealed and installed, and a sealing layer can be set around the well cover 1, so that the well can withstand high pressure backwater pressure.

[0024] A water outlet pipe 2 and two (or more) return water branch pipes 31 and 32 are provided through the well cover 1 at the same time. The water outlet pipe 2 is a flexible pipe, and a hard water outlet pipe casing 4 is set on the outside of the flexible pipe to form a composite water outlet pipe. The upper end of the outlet pipe casing 4 is fixed on the lower surface of the well cover 1 . The outlet pipe 2 cooperates with the hard outlet pipe casing 4 in a gap to form an air-insulated interlayer to prevent heat exchange between the high-temperature return water and the low-temperature pumping pipe 2 . It can be seen t...

Embodiment 2

[0032] Example 2: Participation figure 1 and image 3 , the content is basically the same as that of Embodiment 1, and the similarities will not be repeated. The difference is that the isolation layer is fixed with n tapered pistons 72 from top to bottom on the outer wall of the hard outlet pipe casing 4 At the same time, n tapered holes 62 are fixed from top to bottom on the inner wall of the supporting section of the supporting permeable pipe 5; each tapered piston 72 is matched with the corresponding tapered hole 62 and sealed together to form n isolated layer, n is an integer greater than 1.

Embodiment 3

[0033] Example 3: Participation figure 1 and Figure 4 , the content is basically the same as that of Example 1, and the similarities will not be repeated. The difference is that the isolation layer is fixed with n sealing rings from top to bottom on the outer wall of the hard outlet pipe casing, and at the same time The inner wall of the support section supporting the permeable pipe is fixed with n concave column sections from top to bottom; each sealing ring is matched with the corresponding concave column sections, squeezed and sealed together to form n isolation layers.

Abstract

The invention discloses a hose type water outlet and return device in the same water source well for a water source heat pump central air conditioner. A wellhead of the same water source well is provided with a well cover in a sealing way, and is provided with a water outlet pipe and a water return pipe, wherein the water outlet pipe is a hose, and the outer side of the water outlet pipe is sleeved with a hard water outlet pipe sleeve. The groundwater is pumped out by a submersible pump through the water outlet pipe to the central air conditioner, and pressure is exerted into the water return pipe. A plurality of water return spaces arranged in the water source well seep outwards and downwards and exchange heat through an annular seepage layer and a soil layer. An equal amount of effluent water and returned water is realized in the same water source well, and fully exchanges heat with soil, the space and resources are saved, and the implementation is easy. The water resource circulates in a sealing way in the whole process, so the water is not polluted, and the groundwater is not wasted; the direct heat exchange between effluent water and returned water is thoroughly eliminated, so that the constancy of effluent water temperature is kept, and the efficiency of a water source heat pump unit is substantially improved. The situation that the groundwater level drops or even dries up due to movement is avoided, so that the stability of an underground structure and the security of surrounding buildings are ensured.

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, and the invention is a new type of hose-type well outlet and return water device for water source heat pump central air conditioners. 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. At presen...
