Distribution type energy and underground water source thermal pump coupling system

Abstract

The invention discloses a distribution type energy and underground water source thermal pump coupling system. Natural gas is burnt by a gas engine to drive an electric generator, and the electric generator is used for generating electricity to drive an underground water source thermal pump to produce a part of heat; meanwhile smoke exhausted by the gas engine enters into an absorption type thermal pump, the absorption type thermal pump is used for absorbing the heat of smoke exhausted by the gas engine, a heat supply pipeline is used for directly supplying heat for a building, the tail gas of the smoke exhausted by the absorption type thermal pump after supplying heat enters into a condensation heat exchanger, and thus the other part of heat is recycled; and during the recycling process of waste heat, the waste heat of the smoke exhausted by the condensation heat exchanger takes up 10 percent of the amount of heat produced by combustion of total natural gas, through a steam-water heat exchanger, the waste heat exhausted by the condensation heat exchanger is substituted into underground water of the underground water source thermal pump system, so that at least 9 percent of waste heat can be recycled, the temperature of the underground water rises 2 DEG C, and meanwhile the efficiency of the thermal pump is improved by around 6 percent a second time due to the temperature rise of underground water.

Description

technical field [0001] The invention relates to a distributed energy and water source heat pump coupling system, in particular to a distributed energy and ground water source heat pump coupling system. Background technique [0002] In recent years, in order to alleviate the impact of global climate change on human survival, countries around the world have raised energy efficiency and the promotion of clean energy development as national strategies. As the best way to scientifically use energy in the 21st century, distributed energy is booming and has been widely valued and applied by countries all over the world. There are now more than 6,000 regional energy stations in the United States. The total installed capacity of regional energy stations in Japan reaches 9.2 million kilowatts, 50% of which use natural gas as fuel. Natural gas cooling, heating and power trigeneration system, Denmark's distributed energy accounts for half of its total energy. Natural gas occupies an i...
