Variable air volume air supply system for subway equipment management rooms and controlling method thereof

Abstract

The invention discloses a variable air volume air supply system for subway equipment management rooms and a control method thereof and relates to the field of building energy saving and air conditioner ventilation control. The variable air volume air supply system comprise a fan, an air supply dry pipe electric air valve, electric air volume adjusting valves, a main control cabinet, a tail end control cabinet, temperature sensors and a static pressure sensor. The fan is arranged at a port of an air supply dry pipe. The air supply dry pipe electric air valve is arranged on the air supply dry pipe. The electric air volume adjusting valves are arranged on air supply branch pipes. Each temperature sensor is arranged in the corresponding subway equipment management room. The static pressure sensor is arranged at the tail end of a pipeline of the air supply dry pipe. The main control cabinet is electrically connected with the fan, the air supply dry pipe electric air valve and the static pressure sensor simultaneously. The tail end control cabinet is electrically connected with the electric air volume adjusting valves and the temperature sensors simultaneously. The invention further provides the control method of the variable air volume air supply system. The thermal comfort of the subway equipment management rooms is improved, and meanwhile efficient and energy saving operation of a whole transmission and distribution system is achieved.

Description

technical field [0001] The invention belongs to the field of building energy saving and air conditioning and ventilation control, and in particular relates to a variable air volume air supply system and a control method for a subway equipment management room. Background technique [0002] With the continuous development of cities in our country, the population of central cities is increasing, which also promotes the development of subway construction. The subway air-conditioning system is very complex and huge, and its proportion in the energy consumption of the entire building is also increasing. Usually, the subway equipment management room adopts a constant air volume air supply system, which is easy to control and easy to use. At the same time, the constant air volume air supply system also has many disadvantages because it cannot adjust the air supply volume of each equipment management room. The constant air volume air supply system has poor adjustable performance an...
