Hydraulic pressure type grade well

Abstract

The invention discloses a hydraulic pressure type grade well and relates to the technical field of well making engineering, in particular to a well special for an underground water source heat pump. The hydraulic pressure type grade well comprises a well body, a built-in pipe, a sealing bag, a water replenishing tank and a hydraulic pressure pipe and is characterized in that the built-in pipe is arranged in the well body and is divided into an upper built-in pipe and a lower built-in pipe; the sealing bag is fixed to the middle of the lower built-in pipe; the upper built-in pipe is located above the sealing bag; and the water replenishing tank is arranged on the upper portion of the well body and is connected with the sealing bag through a hydraulic pressure pipe. Through separation of thesealing bag, the well body form different grades, water can be taken and can also return, and the purpose of multiple purposes of one well 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
