Percolation water intaking device of surface water source heat pump central air conditioning system and method thereof

Abstract

The invention discloses a percolation water intaking device of a surface water source heat pump central air conditioning system. The device comprises an outdoor water intaking part and an indoor water intaking part. The device is characterized in that the outdoor water intaking part comprises at least one water intaking well, wherein a spiral steel pipe is arranged in the water intaking well as a well wall of the water intaking well; gravels are filled at the periphery and bottom of the water intaking well; a percolation pipe for percolating the water source is arranged at the middle part of the spiral steel pipe; the lower part of the percolation pipe is connected with a precipitation pipe for precipitating micro sediment of the water source; a submerged pump for extracting the water source is arranged in the water intaking well; the submerged pump is arranged at the percolation pipe in the water intaking well. The invention further discloses a percolation water intaking method. By adopting the technical scheme, the water volume is improved; the water temperature can satisfy the requirement for heating load or cooling load for a user; the water quality does not generate decadent damage to the set equipment.

Description

technical field [0001] The invention belongs to the technical field of renewable energy, and in particular relates to a percolation water intake device and a method thereof for a central air-conditioning system of a surface water source heat pump. Background technique [0002] The surface water water source heat pump central air conditioning system is a heating and air conditioning system composed of a water source heat pump unit, a geothermal energy exchange system, and a building system, which uses rock and soil, groundwater or surface water as a low-temperature heat source. Its working principle is: in winter, the heat pump unit absorbs heat from the ground source (shallow water body or rock formation) to heat the building; in summer, the heat pump unit absorbs heat from the room and transfers it to the ground source to realize air conditioning and cooling of the building. According to the different forms of geothermal exchange system, ground source heat pump system is di...

AI Technical Summary

Problems solved by technology

[0003] The existing percolation water intake system directly takes river water as a cooling water source for the central air-conditioning system. Because the water temperature of the river is often affected by the harsh environment, the water temperature is relatively high, which is not suitable for the central air-conditioning system, and the water quality of the river is relatively poor. , the water quality is easy to cause corrosion damage to the unit equipment
