Design of power saving in water supply of deep wells

Central air conditioning of ground energy(CACGE) is a new type of air-conditioning system of energy saving and pollution-free,the energy of exchanging comes form groundwater in deep wells. The authors study on how the water level changes with the seasons, then provided the method of energy saving and developed a device to realize energy saving. According to the design of mechanism, using the sensor to detect water levels, and using the PLC to control roll shaft, so the depth of the submergeol pump can be adjusted automaticly according to the water lever of dry season or wet season. Also it is controlled by frequency converter, so geothermal central air-conditioning´s water stress is sure to be stable, and reaching a power-saving purposes.
