Dynamic optimization method of environmental control parameters in subway station based on RWI index

Abstract

The invention belongs to the field of air conditioning, and relates to a dynamic optimization method of environmental control parameters in a subway station based on an RWI index. The optimization method comprises the following steps of setting the RWI value of the maximum relative heat index in the station according to the environmental parameters outside the subway station collected in real time; preliminarily setting the environmental parameters of each area in the station; drawing an RWI value change curve of passengers during the whole subway ride; determining the step-up position of theRWI value in the station; adopting a local optimization measure to reduce the RWI value in the area; in the area of reducing the RWI value, raising setting values of temperature and humidity as a whole; according to the rules for determining the thermal comfort environment parameters of human body in the station, determining a plurality of the setting values of the environmental parameters; and selecting the setting value of the environmental parameters to minimize the load of an air conditioning in the station. By means of the dynamic optimization method, the influence of different environmental parameters outside the station on the thermal comfort of the passengers inside the station is fully considered, the setting values of the environmental parameters inside the station according to the changes of the environmental parameters outside the station in real time can be dynamically adjusted, and the local optimization measure is adopted for the larger thermal sensation inside the station, so that the thermal comfort needs of the human body in the station are met, and the energy consumption of the air conditioning is saved.

Description

technical field [0001] The invention belongs to the field of air conditioning and relates to a dynamic optimization method for environment control parameters in subway stations based on RWI index. Background technique [0002] With the continuous expansion of the scale of cities in our country, the urban rail transit represented by the subway has been vigorously developed, but the energy consumption of the operation of the subway remains high, and the energy consumption of the ventilation and air conditioning system of the subway accounts for a large part. According to reports, the energy consumption of ventilation and air conditioning systems in subway stations has accounted for more than 30%-40% of the total energy consumption of the station. Therefore, the energy-saving optimization control system and strategy of the central air-conditioning system in the subway station have a broad demand background and important application value. [0003] The subway station is a place...
