Ventilation and air conditioning system applied to subway environment control system

Abstract

The invention discloses a ventilation air-conditioning system for a subway environmental control system. The ventilation air-conditioning system comprises a ventilation air-conditioning unit and an evaporation condensation cold water unit, the ventilation air-conditioning unit is connected with the subway environment, the ventilation air-conditioning unit is connected with the evaporation condensation cold water unit respectively through an air pipe network and a water pipe network, and the subway environment is externally connected with an air return pipe. The ventilation air-conditioning system for the subway environmental control system solves the problems of high energy consumption of an existing subway environmental control system and difficult setting of a cooling tower, the ventilation air-conditioning system and the evaporation condensation cold water unit are combined, the ventilation air-conditioning unit performs pre-cooling for fresh air by the aid of return air, so that different working conditions can be realized, the ventilation air-conditioning system is high in efficiency, the cooling tower is omitted, and energy is saved.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning and refrigeration equipment, and in particular relates to a ventilation and air-conditioning system applied to a subway environment control system. Background technique [0002] With the acceleration of urban rhythm, the subway has become a common means of transportation for people's daily travel. However, the subway is a relatively closed place, and the connection with the outside world is through a small number of ventilation shafts, or connected with the entrance and exit. In addition, there are a large number of people and vehicles in the subway, forming a large number of internal heat sources. If the heat cannot be discharged in time, not only the passengers cannot bear it, but it will also affect the operation of the train equipment. Because of this, the subway environmental control system plays a very important role in the operation of the subway. [0003] The existing subway envi...
