AI Technical Summary

Technical Problem

The cooling towers of the air-conditioning system of traditional subway stations occupy a large area, are difficult to arrange, and have high energy consumption. The traditional shallow soil source heat pump occupies a lot of land resources. The medium and deep soil source heat pump can only take heat but not cold, which cannot meet the cooling needs of subway stations.

Method used

The capillary energy wall soil source heat pump air conditioning system is adopted, and the capillary grid buried pipe layer is laid on the inner side of the structural wall. The station waste heat is transferred to the soil through cooling water circulation, and combined with the heat pump unit and the air conditioning terminal equipment, the cooling and heating supply integration is achieved.

Benefits of technology

It solves the problem of cooling towers occupying a high land and energy consumption, saves land resources, realizes integration of cooling and heating, reduces construction costs and energy consumption, and improves energy efficiency.

Abstract

The utility model relates to a capillary tube energy wall ground source heat pump air-conditioning system for a subway station. A traditional underground station air-conditioning system water chilling unit usually adopts a ground cooling tower to eliminate unit condensation heat, and the problems that the cooling tower is difficult to expropriate land and arrange, influences urban landscapes and the like exist. The system comprises a capillary energy wall close to the soil side and used for eliminating condensation heat, and the capillary energy wall sequentially comprises a structural wall, a capillary mesh buried pipe layer, a heat preservation layer, an aluminum tin film, an air interlayer, an aluminum tin film and a wall separation wall from the soil side to the station side; the capillary mesh buried pipe layer comprises a capillary mesh laid on the inner side of the structural wall. According to the utility model, station waste heat is transferred to surrounding soil through the capillary tube mesh grid laid on the inner surface of the structural wall, underground renewable energy sources are extracted for cooling, and a traditional cooling tower is reduced or replaced. The underground heat exchanger is combined with an underground station supporting structure, cold energy in soil can be extracted, heat can also be extracted, and the occupied space of the underground heat exchanger is effectively reduced.
