Problems solved by technology

For some railway passenger cars, especially those that do not need to operate in cold regions, there is no external temperature sensor installed on the bottom of the passenger car. If the cooling and heating inside the passenger car still use the existing passenger car air-conditioning unit, it will undo

Abstract

The invention provides an air conditioning unit of a passenger car. The air conditioning unit comprises a ventilator (1), an evaporator (2), condenser fans (3), a casing (8), a condenser (9), a gas-liquid separator (10) and a compressor (12). The high voltage terminal of the compressor (12), the condenser (9), the evaporator (2), the gas-liquid separator (10) and the low voltage terminal of the compressor (12) are connected by a pipeline to form a refrigeration circulation loop, and a fresh air duct inlet (4) and an air return duct outlet (7) which are communicated with the ventilator (1) are formed in the casing (8). Compared with the traditional air conditioning unit, the air conditioning unit of the passenger car can still meet the refrigeration requirement of common passenger cars under the condition of not changing the duct of the passenger car and the structure of the ventilator, the purchase cost of the air conditioning unit is effectively reduced, the level of energy preservation and consumption reduction during operation of the air conditioning unit is improved, and the modification and operation costs of the air conditioning unit are lowered.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning unit for passenger cars. Background technique [0002] The passenger car air conditioning unit is usually installed on the top of the passenger car, and the integrated control cabinet matching the air conditioning unit is installed in the power distribution room of the passenger car. The air conditioning unit and the integrated control cabinet are connected through electrical connectors (plugs, sockets). The air outlet of the air-conditioning unit is connected with the main air duct in the car through a soft air duct, and the air treated by the air-conditioning unit is sent into the room through the main air duct in the car through the air supply port. Each unit has two independent refrigeration cycle systems, which can be controlled according to the load in the vehicle to achieve flow regulation. The air conditioning unit is controlled by a comprehen...
