Air-conditioner unit used for emergency four-constancy air-conditioning system of high-speed train

Abstract

The invention discloses an air-conditioner unit used for an emergency four-constancy air-conditioning system of a high-speed train. The air-conditioner unit used for the emergency four-constancy air-conditioning system of the high-speed train comprises an air conditioner unit body, a buffering device and an emergency case. Pin holes are formed in the buffering device. The buffering device is mounted on the back side face of the air-conditioner unit body through matching of fixing pins and the pin holes. The emergency case is arranged on the lower portion of the air-conditioner unit body. An emergency power supply and an emergency power supply judgment device are arranged inside the emergency case. One end of the emergency power supply is connected with a power grid of the air-conditioner unit body, and the other end of the emergency power supply is connected with the emergency power supply judgment device. By adoption of the air-conditioner unit used for the emergency four-constancy air-conditioning system of the high-speed train, the phenomena that after an outage happens to the high-speed train due to an emergency accident, the air-conditioning system stops operating, the oxygen concentration in a cabin is decreased, the temperature is increased, and the air is dry are avoided; and the air pressure in the cabin of the high-speed train is guaranteed, oxygen is sufficient, the air is clean, and the temperature and the humidity are moderate, and life safety of passengers on the train is guaranteed more effectively.

Description

technical field [0001] The invention relates to the related technical field of air-conditioning equipment, in particular to an air-conditioning host used in an emergency four-constant air-conditioning system for high-speed rail. Background technique [0002] Air conditioner refers to the process of adjusting and controlling the temperature, humidity, cleanliness, speed and other parameters of the ambient air in the building / structure by manual means, generally including cold source / heat source equipment, cold and hot medium transmission and distribution system , terminal devices and other major parts and other auxiliary equipment. If there is a sudden safety accident on the current high-speed rail, the power grid in the car will be cut off. Although many cars are equipped with emergency power supplies, the emergency power supply is not enough to load the normal operation of the air-conditioning system on the entire high-speed rail. Therefore, there is no air-conditioning sys...

AI Technical Summary

Problems solved by technology

If there is a sudden safety accident on the current high-speed rail, the power grid in the car will be cut off. Although many cars are equipped with emergency power supplies, the emergency power supply is not enough to load the normal operation of the air-conditioning system on the entire high-speed rail. Therefore, there is no air-conditioning system. With the support of the airtight cabin, the oxygen concentration in the airtight cabin will gradually drop, the temperature will rise, and the clean air for passengers to breathe normally will be insufficient, which will threaten the lives of passengers; at the same time, in a sudden accident on the high-speed rail, the There will inevitably be huge shocks in the cabin, which will cause damage to the air conditioner and cause it to fail to operate normally. After being hit, the cushioning effect will be poor, which will seriously affect its service life.
