Control system of CO2 refrigerant air conditioner for locomotive

Abstract

The invention provides a control system of a CO2 refrigerant air conditioner for a locomotive. The control system comprises a control box body, a first control module, an air conditioner execution module and a temperature acquisition module, wherein the first control module, the air conditioner execution module and the temperature acquisition module are arranged in the control box body; the outputend of the temperature acquisition module is connected with the input end of the first control module; the output end of the first control module is connected with the input end of the air conditioner execution module; the temperature acquisition module acquires a temperature signal in the locomotive and sends the temperature signal to the first control module; and the first control module receives the temperature signal sent by the temperature acquisition module, processes the temperature signal, sends an instruction to the air conditioner execution module and controls the air conditioner execution module to act to adjust the temperature. The control module, the air conditioner execution module and the temperature collection module are integrated in the control box, so that scattered devices are integrated together, the space of the CO2 refrigerant air conditioning system is reduced, and the space utilization rate of the control system of the air conditioning unit is increased.

Description

technical field [0001] The invention relates to the field of locomotive air conditioning control, in particular to a CO 2 Refrigerant air conditioning control system. Background technique [0002] With the rapid development of my country's rail transit industry, drivers and passengers have higher and higher requirements for temperature comfort and safety in the car; traditional refrigerant air conditioners have become more and more difficult to meet the latest international requirements for green environmental protection, environmental protection refrigeration Agent CO 2 Refrigerant air conditioners will become the main products to be promoted and used in the future. [0003] Air-conditioning units for locomotives are generally relatively compact in size, and most vehicle types in the prior art require that the air-conditioning control device be integrated in the air-conditioning unit, which directly leads to a reduction in the installation structure and space of the contro...

Problems solved by technology

[0003] Air-conditioning units for locomotives are generally relatively compact in size, and most vehicle types in the prior art require that the air-conditioning control device be integrated into the air-conditioning unit, which directly leads to a smaller installation structure and space for the control system in the air-conditioning unit

But CO 2 Refrigerant air-conditioning systems are more complex than traditional
