Ventilation drying system for tower range of underground garage of high-rise residential building

Abstract

The invention provides a ventilation drying system for a tower range of an underground garage of a high-rise residential building. On one hand, an original exhaust channel of kitchens at a bottom layer of a tower are extended to the inside of the underground garage to form a vertical air channel, on the other hand, heat absorbed for cooling an elevator machine room of the tower in high-temperature seasons is transferred into underground heat radiating pipes laid below the ground in the tower range of the underground garage through a water circulating pump and pipelines, the heated ground radiates heat towards the space so as to gradually raise the temperature of the tower range, thermal pressure ventilation is realized through the vertical exhaust channel, and therefore, the ventilation drying problem on the tower range of the underground garage is solved while the elevator machine room is cooled in the high-temperature seasons.

Description

technical field [0001] The invention relates to the climate control of the top floor and the underground part of the same building, and belongs to the two majors of construction and heating, ventilation and air conditioning; in particular, it relates to a ventilation and dehumidification system within the range of underground garage towers of high-rise residences. Background technique [0002] High-rise residences are equipped with a kitchen exhaust duct and an elevator machine room. The kitchen exhaust duct is designed to go straight from the ground floor to the roof, and is not connected to the underground garage. It does not contribute to the vertical ventilation of the underground garage tower; the elevator machine room The working environment temperature of the motor is required to be below 40 degrees Celsius, and many elevator machine rooms in high temperature seasons exceed this temperature (especially in the vast areas south of the Huaihe River). , the measured dry b...

Problems solved by technology

The main reasons for dampness are: firstly, the temperature in the underground garage is low, and secondly, the natural ventilation conditions in the tower area are poor, and the humid air is prone to condensation; the existing solutions are generally to install mechanical ventilation or dehumidifiers, which consumes a lot of power. It does not meet the requirements of energy saving, and in order to save electricity, most underground garages are rarely turned on for mechanical ventilation or dehumidifiers, which results in severe condensation on the ground around the towers of underground garages, and incidents of people falling and injuring people frequently occur
