Locomotive air conditioning controlling system

Abstract

The invention discloses a locomotive air conditioning controlling system. The locomotive air conditioning controlling system comprises a locomotive air conditioning main control board, a power supply,a condensing fan, a ventilator, a compressor, an electric heater, a fresh air valve, a communication network, a temperature detector, a temperature adjusting switch, a mode controlling switch and a pressure protecting switch connected to the locomotive air conditioning main control board, the power supply is connected with the locomotive air conditioning main control board through a power supplycontrolling port, the condensing fan is connected with the locomotive air conditioning main control board through the input and output controlling ports of the condensing fan, the ventilator is connected with the locomotive air conditioning main control board through the input and output controlling ports of the ventilator, and the compressor is connected with the locomotive air conditioning maincontrol board through the input and output controlling ports of the compressor. The locomotive air conditioning controlling system has the controlling functions such as ventilation, cooling, heating,over-current, temperature detection and fresh air volume adjustment, automatic controlling is achieved through an environment temperature and return air temperature sensor, the manual function is set,and the locomotive air conditioning controlling system can provide the comfortable indoor environment for a locomotive driver cab accordingly.

Description

technical field [0001] The invention relates to the technical field of air conditioning control systems, in particular to a locomotive air conditioning control system. Background technique [0002] An air conditioner, or room air conditioner, is a unit used to provide treated air to a room or closed space or area. Its function is to adjust the temperature, humidity, cleanliness and air velocity of the air in the room or closed space and the area, so as to meet the requirements of human comfort or technological process. [0003] At present, air conditioners can be classified into window type, split wall type, split cabinet type, ceiling type, embedded type, small central air conditioner, etc. according to their appearance, and most of them are used to monitor air temperature and humidity parameters in confined spaces in fixed places. However, the existing air conditioners have a single function and cannot simultaneously have control functions such as ventilation, cooling, he...

[0003] At present, air conditioners can be classified into window type, split wall type, split cabinet type, ceiling type, embedded type, small central air conditioner, etc. according to their appearance, and most of them are used to monitor air temperature and humidity parameters in confined spaces in fixed places. However, the existing air conditioners have a single function and cannot simultaneously have control functions such as ventilation, cooling, heating, overcurrent, temperature detection, and fresh air volume adjustment.
