Abstract

This invention is a heat pump runner type heat transferring system of sewage or surface water source. It relates to a heat transferring system. This invention resolves the question of complex technological flow, difficult clean and maintenance, high initial cost, large floor space and poor running effect. The heat transferring medium export of this system is communicated to the entry of pressure relieving devices. The export of the pressure reliving device is communicated to the entry of the heat transferring medium pump. The export of the heat transferring medium pump is communicated to the entry of the heat pump unit. The export of the heat pump unit is communicated to the heat transferring medium entry of runner type heat transferring device. The sewage directly enters into the runner type heat transferring device for initial heat transfer. The sewage or surface water source entry terminal does not need to arrange filtering net or blocking device. Its blocking will not happen.

Description

technical field [0001] The invention relates to a heat exchange system. Background technique [0002] Urban sewage and surface water (rivers, lakes and seawater) are good low-level, renewable, and clean energy sources, and their development and utilization can be used as heat pump cold and heat sources to provide heating and air conditioning for buildings, that is, sewage or surface water source heat pump heating and air conditioning, are of great importance. energy saving, environmental protection and economic value. Since the sewage or surface water contains a large amount of suspended matter, it is easy to block the heat exchange equipment, and a large amount of impurities will cause serious fouling on the heat exchange wall surface. If water treatment measures are adopted, the initial investment and operation costs will be high, and the simple method Filtration measures and regular cleaning of the heat exchanger, the cleaning of debris on the filter and the cleaning cyc...
