The tri-generation supply and ground source heat pump coupling energy supply system comprises a gas-driven generator, an absorption type cold and hot water unit, a ground source heat pump unit, a buried pipe system and a heat exchanger; a discharge flue of the gas-driven generator is connected with a flue inlet of the absorption type cold and hot water unit, a high-temperature cylinder sleeve water discharge pipe of the gas-driven generator is connected with a water inlet of the absorption type cold and hot water unit, and a high-temperature cylinder sleeve water return pipe is connected with a water outlet of the absorption type cold and hot water unit. The tri-generation supply and ground source heat pump coupling energy supply system can provide electricity, cold load and hot load for a user to meet the electricity use, heating in winter and refrigerating in summer needs of the user. In winter, the tri-generation supply system composed of the gas-driven generator and the absorption type cold and hot water unit and the ground source heat pump system jointly provide heat load for the user, and the ground source heat pump system serves as the main energy supply system; in summer, the tri-generation supply system serves as the main energy supply system, the ground source heat pump system serves as pitch peak to provide cold load for the user, and at the moment, the buried pipe system serves as a heat dissipation unit of the tri-generation supply system to keep the heat balance of an underground system.

Description

technical field [0001] The invention relates to a novel air-conditioning energy supply system, in particular to an air-conditioning system coupled with a combined energy supply of gas cooling, heating, and electricity and a ground source heat pump. Background technique [0002] Due to its unique advantages and high energy efficiency, the natural gas combined cooling, heating and power system has begun to be gradually valued in today's deteriorating environment. The combined cooling, heating and power supply system mainly uses natural gas to drive the generator to generate electricity, and the absorption hot and cold water unit uses the high-temperature flue gas discharged from the generator and the waste heat of the high-temperature jacket water for cooling or heating. And absorption cold and hot water units generate a lot of heat, which requires cooling measures. [0003] The conventional heat dissipation method of the triple supply system is to configure the corresponding...

Problems solved by technology

[0003] The conventional heat dissipation method of the triple supply system is to configure the corresponding heat dissipation equipment for the generator and the absorption chiller and hot water unit respectively, and the heat of the system is lost to the atmosphere through the circulation of air, which causes a waste of resources to a certain extent, and at the same time Heat dissipation equipment increases the investment of the system to a certain extent

[0005] The triple power supply system and the ground source heat pump system, as the supply methods of clean energy and renewable energy respectively, have not been effectively combined for coupled energy supply.
