Abstract

The invention provides a seawater source heat pump system, relates to a system for extracting cold and heat energy from seawater by heat pump technology, and belongs to the technical field of energy. The invention aims to effectively solve the problems of corrosion prevention, algae prevention, organism prevention, scale prevention, control of conveying energy consumption of a water pump and the like of a seawater source. The system mainly comprises a heat pump machine set, a medium circulation water pump, a medium water supply pipeline, a medium water-returning pipeline and a long straight plastic pipe heat exchange device, wherein the long straight plastic pipe heat exchange device is formed by laying engineering thermally conductive plastic pipes in and fro in a long and straight way along the direction of deep sea, and is sunk to the bottom of the sea; the medium absorbs the cold and heat energy of the seawater at a long distance in the process of flowing in the pipes in and fro; and the heat pump machine set extracts the cold and heat energy from the medium. The seawater source heat pump system of the invention can extract the cold and heat energy of the seawater at the long distance from the deep sea.

Description

technical field [0001] The invention relates to a system for extracting cold and heat in seawater by using heat pump technology, which belongs to the field of energy technology. Background technique [0002] Using heat pump technology to extract cold heat from low-grade, renewable clean energy for heating and air conditioning of buildings is one of the effective ways to save energy and reduce emissions in buildings. These cold and heat sources include: seawater, groundwater, soil, urban sewage, etc. Their temperature is between 0 and 20°C in winter. When they are used as cold and heat sources of heat pumps, the primary energy of the heat pump system (coal, The utilization efficiency of oil and natural gas can reach 133% or even higher, and the energy saving range can be more than 45%. But when using these cold and hot energy sources, in addition to using them according to local conditions, some key problems need to be solved due to their own characteristics. [0003] The k...
