Problems solved by technology
[0003] The invention couples the distributed energy source with the seawater source heat pump system, solves the problem of energy waste caused by the direct discharge of flue gas and waste gas that still has heat after waste heat recovery, and at the same time makes full use of seawater energy, and solves the problem of using seawater source as a low-temperature heat source The problem of low temperature improves the efficiency of energy utilization
[0005] Generally, in the seawater source heat pump system in northern my country, the intermediary water temperature is too low due to the low seawater temperature in winter, which leads to the failure of the seawater source heat pump to start up normally.

Embodiment Construction
[0010] In the figure, the gas engine 1 burns natural gas to drive the generator 2, and the generator 2 generates electricity as the power source for driving the seawater source heat pump 7; at the same time, the flue gas generated by the gas engine 1 enters the absorption heat pump 4, and the absorption heat pump 4 prepares The heat directly supplies heat to the building through the heating pipe 11; the flue gas tail gas discharged from the absorption heat pump 4 enters the condensing heat exchanger 3; the flue gas discharged from the condensing heat exchanger 3 enters the steam-water heat exchanger 5. The exhaust gas after heat exchange is discharged through the exhaust gas discharge pipe 8; the seawater inlet pipe 10 introduces seawater into the water-water heat exchanger 6, and the water-water heat exchanger 6 sends the intermediary water after heat exchange into the steam-water heat exchanger 5, The waste seawater after heat exchange is discharged through the seawater disch...

The invention discloses a distributed energy resource and seawater source heat pump coupling system. A gas engine combusts natural gas to drive a power generator, the power generator generates power to drive a heat pump to generate one part of heat, and smoke gas generated by the gas engine enters an absorption heat pump so as to provide the other part of heat; and in a waste heat recovery process, the waste heat of the smoke gas exhausted by the condensation heat exchanger accounts for 10 percent of the heat generated by combusting all natural gas. According to the invention, the heat is replaced to medium water of a seawater source heat pump system through a steam-water heat exchanger, at least 9 percent of waste heat can be recovered, the defect of overlow temperature of the medium water after the heat in seawater is exchanged by a water-water heat exchanger can be made up, and the temperature of the medium water can be increased by 2 DEG C; and meanwhile, by increasing the water temperature of the medium water, the efficiency of a heat pump can be increased by about 6 percent.
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 seawater source heat pump coupling system. Background technique [0002] With the increase of electricity demand and the aggravation of world energy crisis, adjusting energy structure, improving energy utilization rate, improving energy security, and solving environmental pollution have become the focus of my country's energy strategy. The distributed energy system is a multi-connected total energy supply system based on the concept of energy cascade utilization. According to the different needs of users for energy on the demand side, the energy supply mode of "corresponding temperature and cascade utilization" is realized. The loss of links is minimized, so as to maximize energy efficiency and environmental benefits. Natural gas distributed energy uses natural gas as fuel. After the gas turbine burns natural gas to gener...
