Device for regulating building environment by using city pipe gallery air

Abstract

The invention discloses a device for regulating the building environment by using city pipe gallery air. The device comprises a building, an air extracting chamber formed under the ground surface, a comprehensive pipe gallery under the city ground surface, and a vertical air supplying main pipe arranged on the ground surface; and an air extracting machine is mounted in the air extracting chamber,and the air extracting chamber communicates with the comprehensive pipe gallery through an air extracting channel under the ground surface. Air is cooled or heated by utilizing the underground pipe gallery air, so that the temperature of the air in the pipe gallery is lower than the ground temperature in summer and higher than the ground temperature in winter; then the threes modes that the air extracting machine directly extracts the pipe gallery air, or the pipe gallery air is utilized to be subjected to heat exchanging, or the pipe gallery air serves as the air source heat pump low-grade heat source are adopted to conduct heat supplying, ventilating and air regulating on the building, and thus the energy saving purpose is achieved. The device is environmentally friendly, and directly utilizes the city built pipe gallery, so that the capital cost that a tunnel needs to be built specially for utilizing tunnel air in the past is saved, and the initial investment is saved.

Description

technical field [0001] The invention relates to the utilization of air in urban underground comprehensive pipe gallery in building HVAC, in particular to a device for regulating the building (heat) environment by using the air in urban pipe gallery. Background technique [0002] my country's use of tunnel wind to cool down began in the 1970s. It is based on the storage of natural cold and heat energy by the strata. The use of tunnels to cool or heat the air makes the air temperature in the tunnels lower than the surface temperature in summer and higher than the surface temperature in winter. temperature. An energy-saving technology that sends tunnel air to the ground through the ventilation system to adjust the indoor thermal environment. The theoretical research on the heat transfer law of tunnel wind, heat transfer calculation, and various factors affecting cooling has become mature and widely used in engineering practice. The effect of tunnel wind on the adjustment of th...
