China will become a major source of ground source heat pump within five years

According to new statistics in 2012, the total amount of water and ground source heat pump units nationwide has reached 3.38 billion, currently ranking second in the world, second only to the United States, and continuing to grow by more than 20% for 5 years. This is the past year. One of the fast-growing air-conditioner products has already been developed at a rate that China will become a major source of ground-source heat pumps within five years.

Ground-source heat pump is a highly efficient and energy-saving air-conditioning system that can provide homes with both winter heating and summer cooling by using shallow geothermal resources (including groundwater, ground temperature, surface water, and soil). The ground source heat pump system transfers a small amount of electrical energy to transfer energy from low temperature level energy to high temperature level. Since the shallow ground temperature is constant all year round, the winter temperature is higher than the outdoor temperature, and the summer temperature is lower than the outdoor temperature, which can be used for both winter heating and summer Refrigeration, taking winter heating as an example, a ground-source heat pump system can obtain 4-5 KW of heat for each 1 KW of output energy, and the main energy source is underground thermal energy. The heat pump unit will not produce waste gas, waste water, and waste residue. It is a "green air conditioner" that is both energy-saving and environmentally friendly. Can be used in business buildings, factories, hotels and residential.

As air pollution becomes more serious, the energy consumption of residential buildings, which are large energy consumers, accounts for 12.6% of the country’s total energy consumption. The annual energy consumption of only one heating unit accounts for 11.5% of the country’s total energy consumption. It accounts for more than 20% of the total energy consumption in the heating area. In some severely cold areas, the energy consumption of residential buildings even reaches 50% of the social energy consumption. Energy saving and emission reduction of building energy consumption has become an important issue for the entire society. Energy-saving and environmentally friendly ground source heat pumps The air-conditioning system has become an excellent choice to solve this problem. In this form, many cities have vigorously promoted the implementation of ground-source heat pump air-conditioning systems according to their own conditions.

In the United States, ground-source heat pump air-conditioning systems account for 40% of the total air-conditioning system and are the energy-saving and environmental-friendly technologies that the U.S. government has promoted. In 1998, the U.S. Department of Energy promulgated laws and regulations that required the use of ground-source ground heat pump ground-source heat pump air-conditioning systems in buildings throughout the federal government. In order to show support for this technology, U.S. President Bush also installed the ground source heat pump air conditioning system in his villa in Texas. Nowadays, in Switzerland, Sweden, Austria, and Denmark in Central and North Europe, the use of ground-source heat pump (soil heat exchanger) technology is in an excellent position, and ground-tube soil heat exchanger heat pumps have been widely used.

In the past 10 years, ground source heat pump air conditioning systems have been widely promoted throughout the country. Governments across the country have subsidized this kind of energy-saving technology in varying degrees. According to the policy, any building that adopts water (ground) source heat pump technology can obtain government policy support by reporting to the local government and reduce the cost of building support. 140-200 yuan/m2m2. It is understood that during the "12th Five-Year Plan" period, the domestic plan to complete the ground source heat pump heating and cooling 350 million square meters, development and utilization of at least 70 billion yuan. In response to this background environment, local governments and various manufacturers responded positively and started policy formulation and project development for water source heat pump projects in line with local conditions.
