Embodiment 1

[0023] Embodiment 1: The first kind of water source heat pump central air-conditioning hard tube 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 return water branch pipes 31 and 32 are simultaneously arranged on the well cover 1 . The water outlet pipe 2 goes deep into the underground water space A at the bottom of the well to communicate with the groundwater, and the water inlet at the lower end of the water outlet pipe 2 is connected with the submersible pump 10 to form a high-pressure water outlet passage. The return pipe 3 communicates with two return branch pipes 31 and 32 at the same time, and applies pressure to the return pipe to form a high pressure return passage.

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 outlet pipe casing 4, and at the same time n tapered holes 62 are fixed on the inner wall of the supporting section supporting the permeable pipe 5 from top to bottom; each tapered piston 72 is matched with the corresponding tapered hole 62 and sealed together to form n isolation layers.

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 outlet pipe casing, and at the same time, it is fixed on the support The inner wall of the support section of 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, extruded and sealed together to form n isolation layers.

Abstract

The invention discloses a hard-pipe type water outlet and return device in the same 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 outer side of the water outlet pipe is sleeved with a water outlet pipe sleeve to form a composite water outlet pipe, and the water outlet pipe and the water outlet pipe sleeve are formed by butting steel pipes and are antiseptically treated. 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, so that the efficiency of a water source heat pump unit can be substantially improved. 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. Therefore, the water resource is not avoided, and 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 conditioning, in particular to a water source well hard pipe type same well outlet and return water device for water source heat pump central air conditioning. 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...
