Embodiment 1

[0024] As shown in Figure 1, it consists of water source heat pump unit 3, water source circulating water pump 2, user circulating water pump 4, sewage heat exchange coil 1, fan coil 5, expansion water tank 6, pipeline control valves 7, 8 and corresponding pipelines , wherein, the sewage heat exchange coil 1 is set in the sewage pool 9, and is connected with the circulating water pump 2 on the water source side, the pipeline control valve 7, and the water source heat pump unit 3 through the pipeline, and then connected to the pipeline and the pipeline control valve 8. The sewage heat exchange coil 1 sent back to the sewage pool 9 forms a water source side circulation loop; the water source heat pump unit 3 is connected with the pipeline control valve 8, the user circulating water pump 4, and the fan coil unit 5 through pipelines, and the fan coil unit 5 passes through the pipe The road and pipeline control valve 7 and the water source heat pump unit 3 form a user-side circulati...

Embodiment 2

[0027] Referring to FIG. 2 , the heat exchange coil 1 in Embodiment 1 is arranged in a horizontal serpentine shape.

Embodiment 3

[0029] Referring to FIG. 3 , the heat exchange coils 1 in Embodiment 1 are vertically arranged.

Abstract

A recovery device of waste water heat energy from aluminium-plastic pipe indirect heat exchange is prepared for forming user side circulation loop by waste water heat exchange coil, water source side circulation water pump, pipeline control valve, etc; sending the working media back to waste water heat exchange coil for recirculation after heat is obtained through water source heat pump set, sending said working media to fan coil for absorbing heat through user side circulation loop and sending heat exchanged cold working media to water source heat pump set for recirculation through connection pipeline.

Description

technical field [0001] The invention discloses a sewage heat recovery and utilization method for indirect heat exchange of aluminum-plastic pipes, and also provides a corresponding device for energy-saving and environment-friendly heating and air-conditioning projects, belonging to the technical field of heating and air-conditioning devices. Background technique [0002] In recent years, with the gradual enhancement of people's awareness of environmental protection, the reduction of the total amount of natural fuels and the continuous rise of fuel prices have prompted people to continuously explore new clean energy and energy-saving and environmentally friendly heating and cooling technologies, and have achieved Certain results. As a renewable clean energy, sewage thermal energy has attracted more and more attention. Using heat pump system to recover the heat energy in urban sewage not only develops a clean energy, but also reduces the emission of urban waste heat and protec...
