A Long Tunnel Air Source Cooling Equipment

Abstract

Long-tunnel air-source cooling equipment is mainly composed of the two parts of a water way system and a control system. The water way system is mainly composed of the three parts of a cold water supply subsystem arranged on the ground, an air source heat pump installed in a long tunnel and a hot water utilization subsystem arranged on the ground, and the cold water supply subsystem, the air source heat pump and the hot water utilization subsystem are sequentially connected to form a circulating water way through two water supply pipelines; and a controller, a water suction pump, a flow control valve, a temperature sensor, a check valve and a pressure gage are mainly connected through an electrifying circuit to form the control system, wherein the controller is arranged on the ground, and the water suction pump, the flow control valve, the temperature sensor, the check valve and the pressure gage are installed on water supply pipelines. According to the long-tunnel air-source cooling equipment, construction is simple, energy consumption is low, safety and high efficiency are achieved, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of long tunnel cooling, in particular to long tunnel air source cooling equipment. Background technique [0002] In recent years, with the development of the economy, the available ground area has gradually decreased. In order to alleviate the inconvenience caused by ground production and traffic congestion, more and more underground projects have emerged. Underground tunnel traffic has become very common. Considering the land utilization rate and the convenience of traffic, the trend of increasing the length and depth of tunnels is becoming more and more obvious, and the problem of heat damage in tunnels is becoming more and more serious. For tunnels with short length, shallow buried depth and small traffic flow, the problem of heat damage can be basically solved by adopting non-artificial cooling methods such as increasing tunnel ventilation, but for more and more tunnels with shorter lengths For long tun...

AI Technical Summary

Problems solved by technology

[0006] 1) For long tunnels, long cold water pipes need to be laid, resulting in high cooling consumption and high power consumption;

[0007] 2) While the cold water pipe lowers the air temperature, the hot water pipe will absorb the cold energy in the air, and the efficiency is not high
