Subway station ground source heat pump air conditioning system

Abstract

The invention provides a subway station ground source heat pump air conditioning system which comprises a ground source heat pump set, a ground heat exchanger, water storage tanks, a plurality of subway station air conditioning terminals and a plurality of surrounding building air conditioning terminals. The ground source heat pump set comprises a ground source side heat exchanger and a load side heat exchanger. The ground heat exchanger is connected with the ground source side heat exchanger. The water storage tanks and the subway station air conditioning terminals are all connected with the load side heat exchanger through pipelines, and the water storage tanks are connected with the subway station air conditioning terminals in parallel. The surrounding building air conditioning terminals are connected with the water storage tanks through pipelines. The subway station ground source heat pump air conditioning system can satisfy the requirement for an air conditioning load of a subway station, and has the advantages of being low in noise, good in economy, wide in range of use, efficient and energy saving, and stable in running.

Description

technical field [0001] The invention relates to the technical field of building energy saving and noise reduction, in particular to a ground source heat pump air conditioning system for a subway station. Background technique [0002] Ground traffic congestion has become a common prominent problem in many cities in our country. With its advantages of large capacity, fast speed, accurate time, less pollution, safety and comfort, the subway has increasingly become an inevitable choice for improving urban traffic conditions. [0003] Most of the subway stations are built in the bustling areas of the city, and the cooling towers used in the current subway environmental control design have the disadvantages of large footprint, high noise, high heat generation, and great impact on the environment, and are not suitable for use in many prosperous areas. . On the basis of meeting the comfort requirements, the ground source heat pump air-conditioning system also has the characteristi...

AI Technical Summary

Problems solved by technology

[0004] The utility model patent with the Chinese patent application number CN201020046907.9 discloses a new type of ground source heat pump air conditioning system, which uses a cooling tower to assist the ground source heat pump, thereby solving the problem of soil thermal imbalance around the buried pipe heat exchanger

However, the cooling tower is still selected for this system, which is noisy and not suitable for the application of the subway station in the central area of ​​the city. In addition, the air conditioning system has a low utilization rate in winter and poor economic efficiency
