Abstract

The invention relates to a waste heat utilization system and method based on an electrically-driven water source heat pump unit. The system comprises a control center, a power plant circulating watersystem, the electrically-driven water source heat pump unit and a terminal heat exchange device. The power plant circulating water system and the electrically-driven water source heat pump unit are connected end to end through a pipeline to form a first circulating loop. The terminal heat exchange device and the electrically-driven water source heat pump unit are connected end to end through a pipeline to form a second circulating loop. The electrically-driven water source heat pump unit comprises a first heat exchange device and a second heat exchange device. A control switching device of thecontrol center selectively connects the first heat exchange device to the second circulating loop and connects the second heat exchange device to the first circulating loop, or connects the second heat exchange device to the second circulating loop and connects the first heat exchange device to the first circulating loop, and thus switching between a heating mode and a refrigerating mode of the electrically-driven water source heat pump unit is achieved. The problems that in the prior art, the heat pump technology is low in utilization rate in south areas, and recycled waste heat cannot be used for refrigeration are solved.

Description

technical field [0001] The invention relates to the technical field of waste heat utilization in thermal power plants, in particular to a waste heat utilization system and method based on an electric-driven water source heat pump unit. Background technique [0002] The waste heat utilization technology of thermal power plants has been widely used. By recycling the waste heat of thermal power plants, it can effectively reduce the production energy consumption of power enterprises and improve the comprehensive energy utilization level of power plants. [0003] Because of its high efficiency, energy saving and environmental protection, heat pump technology has attracted great attention from national and local governments. With the maturation and rapid development of heat pump technology, it is widely used in northern China. Thermal power plants discharge a large amount of steam, and steam drives water source heat pump units to recover waste heat from thermal power plants and us...
