Abstract

The invention discloses a control method, device and system for a rail vehicle air conditioning system, wherein the control method for the rail vehicle air conditioning system comprises the following steps of obtaining PMV parameters of a rail vehicle in different PMV index areas and establishing a PMV evaluation formula; obtaining a temperature control curve by fitting according to the PMV evaluation formula; and controlling the air conditioning system to adjust the temperature according to the temperature control curve. According to the control method, device and system for the rail vehicle air conditioning system, the influences of the PMV parameters on body comfort levels of passengers in the process of controlling the rail vehicle air conditioning system are considered in a comprehensive manner so that the taking comfort levels of the passengers during taking the rail vehicle are improved.

Description

technical field [0001] The invention relates to the field of air conditioning system control, in particular to a control method, device and system for a rail vehicle air conditioning system. Background technique [0002] Today, with the rapid development of my country's economy, the air conditioning system of rail vehicles plays a very important role in meeting the requirements of ride comfort and improving the quality of vehicle operation. For rail vehicles, due to their own operating characteristics and conditions, passengers have special requirements for comfort in temperature and humidity conditions. However, in the control process of the traditional rail vehicle air-conditioning system, the influence of PMV parameters such as air temperature, relative humidity, air velocity, average radiant temperature, metabolic rate and clothing thermal resistance on the passenger comfort is not considered comprehensively. [0003] For the above problems, no effective solution has be...
