Self-adaptive multi-area series-connected multifunctional independent cycling air disposal system for multiple units

Abstract

The invention provides a self-adaptive multi-area series-connected multifunctional independent cycling air disposal system for multiple units. The self-adaptive multi-area series-connected multifunctional independent cycling air disposal system is characterized in that a compartment is divided into a plurality of independent space physical areas; an independent modularized air-disposal air box isarranged in each of the areas; the all air-disposal air boxes are connected in series through a heat insulation air pipe; each of the air-disposal air boxes comprises an air-disposal air box body, a new top air box, a filtration and sterilization module, a temperature sensor and a variable-frequency air feeder; a new air inlet and a new air outlet are formed in the corresponding top new air box; each top new air box communicates with each air-disposal air box body through each new air outlet; the each filtration and sterilization module is arranged in the each air-disposal air box body so as to divide the each air-disposal air box body into a mixed chamber and an air volume adjusting chamber; a passenger compartment air return hole is formed in the mixed chamber; the variable-frequency airfeeder and the temperature sensor are arranged in the air volume adjusting chamber; and an air feeding hole is formed in the air volume adjusting chamber. According to the air-disposal air boxes disclosed by the invention, the design of modularization is adopted, mounting and maintenance are convenient.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle air conditioning, and in particular relates to an adaptive multi-area serial connection multifunctional independent circulating air treatment system. Background technique [0002] The air in the compartment of the EMU is uniformly processed by the air-conditioning unit, and a single set of air supply fans are sent in and recovered through the centralized air duct to form a single-cycle in-car air system along the longitudinal passenger compartment area to meet the consistent temperature and humidity of the entire internal passenger compartment. and other comfort requirements. The air conditioner unit centralizes the circulating air, which can easily cause pollution at any location and the virus will quickly spread to the entire cabin. At the same time, the energy required to adjust the temperature of the compartment is determined by the enthalpy of the incoming airflow, which can only be use...

Problems solved by technology

The air conditioning unit centralizes the circulating air, which can easily cause pollution at any location and the virus will quickly spread to the entire compartment

At the same time, the energy required to adjust the cabin temperature is determined by the enthalpy value of the incoming airflow. It can only air-condition the cabin as a whole and does not have the ability to adjust regionally. The temperature adjustment accuracy is insufficient regardless of the length, level, and vertical section of the cabin.

Especially under the normalization of the epidemic situation, when there are fewer passengers and the distribution of their seats is more concentrated, the energy consumption of air conditioning is wasted
