Various types of heat pump energy saving and emission reduction.

Heat Pump Energy Saving The first air source heat pump air conditioner uses the atmospheric environment as a heat source, adopts the heat pump principle, and achieves the transfer of low thermal energy to high thermal energy through a small amount of electrical energy output. The air source heat pump air conditioner can realize the three functions of cooling, floor heating, and central hot water, and can save energy by 20%-30% compared to a conventional central air conditioner. At present, heat pump air conditioners have been widely used. The average level of the world is 70%, and Japan is nearly 99% higher. China's average level with the world is basically the same.

Ground source heat pump is a kind of low-grade heat source that uses shallow water sources (groundwater, seawater, river water, lake water, etc.) or underground soil heat sources on the surface of the earth. Through the heat pump and refrigeration cycle, the ground source heat pump can be used for summer air-conditioning and heat supply. Winter heating is used. Ground-source heat pump heating is more economical than conventional electric heating or fuel or gas-fired heating. It usually produces the same amount of heat. The power consumption of ground-source heat pumps is only 1/4 to 1/5 of that of electric heating.

Advantages of energy-saving and emission-reduction: Building energy consumption currently accounts for about 27% of the total energy consumption of the whole society, of which the energy consumption for building heating and cooling accounts for about 60% of the entire building energy consumption. Ground source heat pump as a new technology for building heating and cooling can achieve its purpose by consuming a small amount of electric energy or heat energy.

The state issued a series of policies and regulations to support ground source heat pumps. The National Ministry of Finance and the Ministry of Construction issued the "Implementation Opinions on Promoting the Application of Renewable Energy in Buildings" and the "Interim Measures for the Management of Special Funds for Renewable Energy Construction Applications". During the "11th Five-Year Plan" period, the area of ​​renewable energy applications The proportion of new construction area is more than 25%.

To examine the installation cost, the ground source heat pump system is only 10% more expensive than air cooling. The air-cooled heat pump system recovers the investment cost in less than 4 years, and the ordinary water-cooled unit can recover the investment cost in 5 years. Considering that the ground source heat pump generally has a service life of more than 20 years, it is very economical. With the introduction of new equipment and rising energy prices, the cost will be further reduced and the economic benefits will be more pronounced.
