Method for utilizing shallowly-buried artificial recycled water system for controlling urban thermal environment

Abstract

The invention discloses a method for utilizing a shallowly-buried artificial recycled water system for controlling an urban thermal environment. The artificial drainage is used for storing water to make various water inlet systems and various water outlet system form the drainage in an annular closed connection manner, and shallow soil is used as a water catchment heat retainer to provide a stableheat source heat sink for a heat pump according to the characteristic that the shallow soil is constant in temperature field. The method specifically comprises the following steps that the annular artificial recycled water system is built 30 centimeters deep under the ground surface of an urban area, and then is buried underground shallowly, a water inlet is arranged on one side of the artificialrecycled water system, the water inlet is connected to a municipal sewage pipe network passing sewage recycling system through a water inlet pipeline, a water outlet is arranged on the other side ofthe artificial recycled water system, and the water outlet is connected to a water-consuming system through a water outlet pipeline. According to the method for utilizing the shallowly-buried artificial recycled water system for controlling the urban thermal environment, the shallowly-buried recyclable artificial water regeneration system, a heat pump system and an urban ground surface landscape water system are combined to control the indoor-and-outdoor cold-and-hot environment of the urban area, urban recycled water which is a renewable energy source is integrated and developed in a large-scale manner, and is combined with underground soil to serve as the cold and hot source of the urban area.

Description

Technical field: [0001] The invention relates to a method and composition for regulating and controlling the thermal environment of urban areas, and mainly relates to a method for regulating and controlling the thermal environment of urban areas by utilizing a shallow-buried artificial regeneration water system. Background technique: [0002] The traditional air source heat pump is affected by the change of solar radiation and meteorological conditions, and its coefficient of performance is unstable. The traditional commonly used surface water source heat pump system uses surface water as a cold and heat source. The long-term operation of the heat pump will continuously discharge heat to the surface water system, which will destroy the surface water temperature and other water quality conditions, thereby causing a certain degree of thermal pollution, which will not only affect the original heat pump system. It also causes damage to the ecological environment of the water sys...
