The water source heat pump needs to draw underground water as a basic temperature medium for temperature exchange; because the temperature of the underground water foundation is constant, the heat of the underground water displaced in winter is led into the room for heating; in summer, the cold energy of the replaced underground water is led into the room for refrigeration.

The existing underground water source well generally utilizes a water taking well and a water returning well; after the water in the water taking well is extracted, the cold water or hot water generated after the exchange of the water source heat pump compressor is introduced into the backwater well for recharging or is introduced into a sewer. Because the water source heat pump unit integrally runs on the ground, the pipeline heat insulation measures in winter are improper to treat and are easy to freeze and block, and the whole system is paralyzed. For example, sudden power failure in winter often occurs catastrophically to a water source heat pump system, and the situations that a thawing system is broken down and a pipeline is frozen and cracked frequently occur. Therefore, aiming at the problems, a company designs a vacuum well combination with a built-in evaporator, and in the development and test process, the problem that the well water is turbid and goes up to the sand erosion evaporator is also encountered.

Due to unstable underground conditions of the water well, sometimes silt is pumped by a water pump and enters the evaporator along with water flow to impact the coil pipe, so that the coil pipe is corroded and thinned by the sand, the coil pipe is strained too early, and the service life of the evaporator is shortened. Therefore, overcoming uncertain silt in water becomes the key to solve the problem.
