Abstract

The invention provides a combined type heat pump and heat source system and a method for heat exchanging through a power plant cooling system. The system comprises a power plant hyperbola reinforced concrete cooling tower, a heat exchanger buried in the side wall of the reinforced concrete cooling tower, a cooling tower colleting tank, a collecting tank heat exchanger, a ground heat exchanger, a pipe-diameter-enlarged cooling water pipeline, a cooling water pipe S-shaped pipeline heat exchanger, a heat pump unit, a system controller, a switch valve A1, a switch valve A2, a switch valve B1, a switch valve B2, a switch valve C1, a switch valve C2, a buried pipe manifold, a buried pipe water collector and a heat exchange system circulation pump. According to the method for heat exchanging through the power plant cooling system, waste heat of cooling water of a power plant is effectively utilized, and operation efficiency of the heat pump unit and the power plant cooling tower can be improved.

Description

technical field [0001] The invention relates to a compound heat pump heat source system and method using a cooling system of a power plant for heat exchange. Background technique [0002] A heat pump is a device that can obtain low-grade heat from natural air, water or soil, and output usable high-grade heat through electricity. At present, my country mainly uses three heat pump technologies, namely water source heat pump, ground source heat pump, and air source heat pump. [0003] Water source heat pump is an air-conditioning technology that uses solar energy stored in earth water as a cold and heat source to convert. Water sources include groundwater heat pumps, surface water (river, river, lake, sea) heat pumps, domestic sewage, industrial water, etc. Ground source heat pump is a new type of air-conditioning technology that uses shallow ground energy for heating and cooling, which is highly efficient, energy-saving and environmentally friendly. The ground source heat pu...
