Background

The ground source heat pump system is a high-efficiency energy-saving air conditioning system which can supply heat and refrigerate by using underground shallow geothermal energy resources. The system realizes the transfer of low-temperature heat energy to high-temperature heat energy by inputting a small amount of electric energy, the geothermal energy is respectively used as a heat source for heat pump heating and a cold source for a summer air conditioner in winter, the unit consumes 1kW of energy to obtain cold or heat above 4-5 kW, the energy is derived from underground energy, the system does not discharge any waste gas, waste water and waste residue to the outside, and the system is an ideal 'green air conditioner' and can be widely applied to the fields of office buildings, hotels, schools, dormitories, hospitals, restaurants, markets, villas, houses and the like.

The open-cycle ground-source heat pump system absorbs or emits heat from underground water to achieve the purpose of heating or cooling in buildings.

Open cycle systems are commonly used in water-rich areas to recharge water to aquifers in the soil through a recharge well.

Water pollution, also known as water body pollution, is a phenomenon that various pollutants enter a water body and the quantity of the pollutants exceeds the self-purification capacity of the water body. The water pollution mainly comes from domestic sewage and industrial wastewater, and the common water body pollution substances are as follows: inorganic substances, inorganic toxic substances, organic toxic substances, aerobic pollutants, plant nutrients, radioactive substances, oils and cooling water, pathogenic microorganisms and the like. Groundwater pollution is mainly a phenomenon of quality degradation caused by changes in chemical components, physical properties and biological characteristics of groundwater due to human activities. Subsurface formations are complex and groundwater flows extremely slowly, so once contaminated, water quality can only be restored for at least several decades. Along with the development of the industry in China, more and more industrial manufacturers are established, in order to save cost, a plurality of black manufacturers steal polluted water to the underground, underground water is an important component of fresh water resources, and the underground water plays an important role in the aspects of guaranteeing the lives of urban and rural residents in China, supporting the development of the economic society, maintaining the ecological environment balance and the like, so that the problem of preventing and treating the pollution of the underground water becomes a severe environmental problem.

The whole process only absorbs heat or cold from the underground water, the underground water is not subjected to environment-friendly harmless treatment, and the extraction process of the underground water is not fully utilized.

Therefore, it is necessary to develop a novel multifunctional ground source heat pump unit in view of the above disadvantages.
