Abstract

The invention provides a rail vehicle air conditioner comprising a reheating coiled pipe. The reheating coiled pipe and an evaporator are arranged side by side, and the reheating coiled pipe is located on the side of an air outlet of the evaporator. An inlet of the heating coiled pipe communicates with an outlet of a condenser through a first connecting pipe, an outlet of the heating coiled pipe communicates with an inlet of the evaporator through a second connecting pipe, and a bypass valve capable of adjusting the flow of refrigerants is arranged on the first connecting pipe. The rail vehicle air conditioner has high using safety and reliability, and energy sources can be saved easily. The invention further provides a constant temperature dehumidifying method of the rail vehicle air conditioner. The constant temperature dehumidifying method comprises the step that when the temperature in a carriage is within the proper range and the humidity in the carriage exceeds the proper range, the bypass valve is opened, and a constant temperature dehumidifying mode is started. Safety is high, energy consumption is less, and the comfort in the carriage is improved.

Description

technical field [0001] The invention belongs to the technical field of rail vehicles, and in particular relates to a rail vehicle air conditioner and a constant temperature dehumidification method thereof. Background technique [0002] The compartments of rail vehicles are confined spaces, and the temperature and humidity in the compartments have an important impact on the comfort of passengers. Especially in the Yangtze River Basin, areas south of the Yangtze River and coastal areas, there is a period of time every year when the temperature is suitable but the humidity is much higher than the comfort of the human body. During the rainy season, after the rail vehicle has been running in the above-mentioned areas for a period of time, the heat load in the compartment will be reduced accordingly, but the humidity load will be greatly increased. [0003] The rail vehicle air conditioner uses a compressor for mechanical refrigeration, and the air in the compartment flows through...
