Ground water through the heat pump unit, only the exchange of heat, almost no change in water quality, after recirculation to the formation or re-discharge into surface water, will not cause pollution of the original water source "should be cautious. The climate conditions in Guangdong, Guangzhou and Shenzhen are that the cooling time in summer is very long and the cooling load is relatively large, while the heating demand in winter is very little. The cooling load is much larger than the heating load, and the cooling load is very unbalanced. If there is not enough Of the heating needs to offset the summer cooling load, to achieve hot and cold balance, is not advocating the use of ground source heat pump units to do cold and heat source. Ground source heat pump air conditioning system in China is still an initial stage, the need for local conditions, overall planning, use Energy characteristics and the combination of hydrogeological conditions, and gradually and reasonably promote ground source heat pump air conditioning technology, so as to be conducive to optimizing the energy structure, in the premise of environmental protection, improve energy efficiency. Groundwater treatment Different regions of groundwater quality is different, in fact In the project, the local groundwater quality should be tested, and the groundwater that does not conform to the standard should be tested accordingly When the local sand content is high, it should be treated with filter or sand removal equipment.At present, the common use of small size, high sand removal efficiency, can remove the cyclone sand In accordance with the processing flow matching desander models and the number of some water turbidity greater recharging pipe easily cause the filter and aquifer clogging affect the stability and service life of the water system on the turbidity Large water source, you can install a water purifier to filter.When the iron content in the water is greater than 0.3mg / L, should be installed in the water system, iron removal equipment.In our groundwater iron content generally exceed the allowable value, so before use To carry out iron removal ion bar anti-scale device is a new type of advanced water treatment equipment.It has anti-scaling, descaling, rust, corrosion and other functions, low power consumption, long service life. This equipment is installed horizontally Heat pump unit at the entrance of the pipeline, the installation is simple, without additional set of valves and bypass pipe.Some sources of high salinity, corrosive metal stronger, direct access to the unit will reduce Group of life, if through the water treatment approach to reduce the degree of salinity, the cost is very large.Usually use plate heat exchangers installed in the middle of the heat exchanger, the water source and the unit isolated, so that the unit completely avoid water may The corrosive effect of different degrees of salinity of groundwater should adopt different heat exchange methods and equipment.
