Embodiment 1

[0025] like figure 1 and 2 As shown, the present invention discloses a phase-change energy storage air duct, including: a phase-change energy storage unit 2 arranged in the air duct 1, and the phase-change energy storage unit 2 is used The heat is exchanged to keep the temperature of the gas flowing out of the duct 1 stable. Select a suitable phase-change energy storage unit 2 so that the phase-change temperature of the phase-change energy storage unit 2 is close to the set temperature of the air conditioner. When the temperature of the airflow entering the air duct 1 is high, the phase-change energy storage unit 2 absorbs heat Liquefaction reduces the temperature of the gas in the air duct 1, reduces the difference between the gas temperature and the set temperature, makes the temperature of the gas entering the room or the compartment closer to the set temperature, and avoids the sudden increase in temperature that affects the user experience; when entering the air duct Wh...

Embodiment 2

[0034] The present invention also discloses a vehicle-mounted air-conditioning system for rail vehicles or automobiles, which has the phase-change energy storage air duct as described in Embodiment 1. That is to say, the phase-change energy storage air duct can be used for the vehicle-mounted air conditioner of ordinary cars, and can also be used for the vehicle-mounted air conditioner of rail vehicles such as high-speed trains and bullet trains. It is only necessary to add a phase-change energy storage unit 2 to the existing air duct 1 to Realize the purpose of adjusting the temperature of the airflow entering the compartment, so that the temperature of the gas entering the compartment is stable and the temperature fluctuation is small; When it becomes liquid, the exothermic temperature of the gas in the air duct 1 decreases, and the temperature of the gas entering the compartment drops to a state closer to the set temperature, so as to avoid the hot air flow directly blowing ...

Abstract

The invention belongs to the technical field of air conditioning air flues, and discloses a phase change energy storage air flue and a vehicle-mounted air conditioning system for a railway vehicle or an automobile. A phase change energy storage unit is arranged in an air flue of the air conditioning system, residual heat in a gas is absorbed through phase change heat absorption and release, the heat is released to a lower-temperature gas, the energy is recovered, and energy saving is realized; the temperature of the gas entering a room or a carriage keeps stable, and the user experience is improved; when the air conditioning system fails, the phase change energy storage unit still uses stored cold energy or heat energy to cool or heat the gas entering the air flue, the stable air supply is provided for a certain period of time, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of air-conditioning air ducts, in particular to a phase-change energy-storage air duct used for a vehicle-mounted air-conditioning system for rail vehicles or automobiles. Background technique [0002] The air duct is the air circulation channel in the air conditioning system, and the cooled or heated gas finally enters the room or the compartment through the air duct, and participates in the room or car room temperature adjustment; when the cooling or heating effect of the air conditioning system is unstable, it enters The air temperature in the air duct will deviate from the set temperature, resulting in a high or low temperature of the gas entering the compartment or room, and sudden changes in the inlet air temperature will affect the user experience. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present invention is: to solve...
