Section vacuum well

Abstract

The invention provides a section vacuum well, and relates to the technical field of well building engineering, and particularly relates to a special well for an underground water source heat pump. Thespecial well is composed of a well body, built-in pipes, a conical screw, a conical nut and a well lid. The special well is characterized in that the conical nut is arranged in the middle of the wellbody, wherein the built-in pipes comprise the upper built-in pipe and the lower built-in pipe; the conical screw is fixed to the middle of the lower built-in pipe and meshed with the conical nut, andthe upper built-in pipe is positioned above the conical nut and the conical screw; the well lid is assembled at the upper end of the well body in a sealed mode, the upper built-in pipe and the lowerbuilt-in pipe are led out of the well lid, and the upper built-in pipe, the lower built-in pipe and the well lid are sealed. According to the section vacuum well, the well body can be isolated into different sections through sealed meshing of the conical screw and the conical nut, water can be taken and returned, and the purpose that one well has multiple purposes is achieved.

Description

technical field [0001] The invention relates to the technical field of well-building engineering, in particular to a special well for ground water source heat pumps. Background technique [0002] Nowadays, due to its high efficiency and energy saving, the water source heat pump system can gradually replace the air conditioning system with its function of heating in winter and cooling in summer. In particular, the energy saving effect of water source heat pump is more obvious, and it has gradually become a popular choice for high-density buildings such as homes, schools, hospitals, and office buildings. The standard configuration of the group. The water source heat pump needs to draw groundwater as the basic temperature medium for temperature exchange; because the base temperature of groundwater is constant, the heat displaced by groundwater is introduced into the room for heating in winter; the cold energy of groundwater is introduced into the room for cooling in summer. ...

Problems solved by technology

This will cause loss of water source, or loss of return water temperature, resulting in waste

For example, the groundwater extracted in winter becomes cold water and flows back to the backwater well or sewer after heat extraction, resulting in loss of cooling capacity; the groundwater extracted in summer is turned into hot water after cooling extraction and returns to the backwater well or sewer, resulting in heat loss ; Furthermore, the cost of digging two wells increases
