Compound system of gas-fired combined cooling, heating and power with ground source heat pump

Abstract

The invention discloses a compound system of gas-fired combined cooling, heating and power with a ground source heat pump. The compound system comprises a gas internal combustion engine device. The gas internal combustion engine device is connected to a lithium bromide refrigeration unit that is connected to a flue gas heat exchanger by means of a flue gas duct; the flue gas heat exchanger is connected to a hot water tank that is connected to a ground source heat pump unit by means of a water duct; the lithium bromide refrigeration unit is further connected to a water segregator and a water collector, respectively, and the water segregator and the water collector are both connected to the ground source heat pump unit that is further connected to a heat exchange device. With a breakthrough in a traditional cooling mode using a cooling tower, the compound system of gas-fired combined cooling, heating and power with the ground source heat pump meets the electricity demand and the supply of domestic hot water, and also the requirements of a user on cooling and heating; not only is the water source saved, but also effective utilization of the waste heat is achieved; thus, environmental protection is realized, and the whole system is allowed to be more efficient in energy saving, better in appearance, and lower in operating cost.

Description

technical field [0001] The invention relates to a composite system of gas cooling, heating and electricity triple supply and a ground source heat pump, and belongs to the technical fields of gas distributed energy and ground source heat pumps. Background technique [0002] Energy supply and environmental protection issues have become the main bottleneck restricting China's economic development. To this end, the state will implement a sustainable energy development strategy of "guaranteeing supply, prioritizing energy conservation, optimizing structure, being environment-friendly, and being market-driven". Gas-fired combined cooling, heating and power supply belongs to distributed energy, which is an evolution and development of traditional combined heat and power generation. It is one of the most effective means to achieve energy saving, emission reduction and energy structure optimization, so it is applied in more and more projects. . However, its own technology also has ...

Problems solved by technology

However, its own technology also has certain limitations. For example, the waste heat generated by the unit itself when the generator is generating electricity and the waste heat generated when the waste heat is used for cooling in summer need to install a cooling tower to discharge to the outdoor atmosphere, which not only wastes heat but also increases The amount of water consumed to discharge waste heat increases operating and maintenance costs
