Automatic heat exchange system for well water

Abstract

The invention relates to an automatic heat exchange system for well water. Generally, water air conditioners, ground-source energy air conditioners, and chemical, textile and plastic industries use well water at a temperature of about 15 DEG C to prevent sunstroke and reduce temperature, and water pumps which are easy to damage and waste the electricity are used for pumping water. An investigation concludes that underground water is stored on layers because of different geological structures; moisture over 35 meters to underground has fast penetration, short update time and abundant reservesbecause of short distance to the ground surface; and lower layer well water over 100 meters is naturally penetrated for hundreds of years, generally stays in a scarce and exhausted state and even leads to ground sedimentation because of long-term excessive drawing. Therefore, Chinese government makes explicit orders to seal wells and prohibit exploitation, and carries out recharge water supplementto increase groundwater reserves. The automatic heat exchange system for the well water makes well water automatically rise and circulate to carry out heat exchange by building underground water stream channels and skillfully using siphon water stream energy of upper layer water to lower layer water, achieves double utilization of geothermy and water energy, saves electric power and also increases the groundwater reserves.

Description

Technical field [0001] The invention relates to an automatic heat exchange system for well water. Background technique [0002] As we all know, the temperature of groundwater is maintained at around 15-18℃ all year round, and the maximum temperature difference between winter and summer is more than 20℃. Usually, water air conditioners, ground source energy air conditioners, chemical, textile, and plastic industries often use well water to prevent heatstroke and cool down. Use easily damaged and power-consuming water pumps to pump water. According to investigations and studies, groundwater is stored in layers due to different geological formations. Well water with a depth of 20-35 meters in the plain area is close to the ground and has fast water penetration, short renewal time and sufficient water volume. It is more than 100 meters underground. Because the deep well water is far from the surface, there are multiple layers of clay layers that are difficult to seep. The surface wa...

Problems solved by technology

[0003] According to the law of conservation of energy in physics, when the underground well water (the carrier of heat energy) rises from the ground to the ground and then flows into the heat exchanger, the heat energy, potential energy, and kinetic energy are all changing in this physical process, and the change of water temperature is caused by geothermal energy. Carry out natural compensation supply, a certain weight of groundwater, lift a certain height and overcome the resistance generated by heat exchangers and pipelines, the mechanical energy consumed must have energy supply to be conserved. In the past, the pumping process was carried out by electric-driven water pumps, and the current electric pumps do not , in order to let the well water flow out of the ground automatically for heat exchange, the power energy problem of the water flow must be solved
