As China's reform and opening up, China's economy and technology have undergone tremendous changes. In many areas have already had some international influence. For example, ground source heat pump, which uses less equipment in people's life, but with the development of industries such as China, the demand for such products is increasing. So how should users understand such products, businesses and how to introduce ground source heat pump and promote such products? Ground source heat pump details 1, heat pump industry development: Ground source heat pump is the use of shallow surface water (such as groundwater, rivers and lakes) and the soil source to absorb solar and geothermal energy, heat pump principle, both heat Cooling efficient energy-saving air-conditioning system. Prospect Industry Research Institute released "China Ground Source Heat Pump Industry Development Feasibility Study Report Prospects" study shows that China's ground source heat pump industry has developed rapidly in recent years, all over the ground source heat pump project continues to increase, not only benefited from China's rich heat Resources, related technologies continue to improve, but also benefit from the pressure of energy-saving emission reduction. This paper mainly analyzes the situation of energy-saving and emission reduction in our country, advantages and development status of ground-source heat pump, and future development prospects. 2, ground source heat pump working principle: In nature, the water always flows from the lower to the lower, the heat is always transferred from high temperature to low temperature. People can use water pumps to pump water from a low point to a high point to achieve the flow of water from low to high. The heat pump can also transfer heat from low to high temperatures. 3, the advantages of ground source heat pump Prospect Industry Research Institute through a comprehensive analysis, that the ground source heat pump mainly has the advantages of energy saving, environmental protection, applicability, economy and flexibility, the specific analysis is as follows: energy saving, environmental protection, applicable Sex. 4, the type of ground source heat pump: open system: is the direct use of water for heat transfer heat pump system. The system should be equipped with sand control, anti-fouling, water purification and other devices. Closed system: It is a closed system that injects antifreeze and exchanges energy with water or soil through a heat exchanger in a closed plastic tube buried in the ground. Closed system is not affected by groundwater level, water quality and other factors. 5, the existing problems: limitations and shortcomings The current lack of ground source heat pump technology is the "soil thermal imbalance" problem. In the south, cooling is the main part, and heat is injected into the ground all year round. In winter, there is a big demand for heating in the north, absorbing a large amount of heat from the soil. After long years of operation, soil temperature will be unbalanced and affect the surrounding ecology. Through the introduction of the above 5, we can already clearly understand the basic situation of ground source heat pump. But for users, the use of such products is not enough to know about these situations. The use of a class of products not only to pay attention to the characteristics of the product, but also pay attention to the actual production needs.
