In this paper, based on the Siemens S7-200 programmable controller in the central air conditioning control system, hardware and software of the central air-conditioning control system is designed. In hardware design PLC controller is used as controlling core to control temperature and humidity of the entire process. In the software design, control programming and multi-loop control of temperature, humidity PID algorithm are completed by using PLC programming software STEP7 because of its characteristics that it is easy to read and easy to achieve complete control. Lastly, Related parameter is set and the information is displayed by touching screen.

Abstract Traditional fuel vehicles consume a lot of fuel and cause serious environmental pollution. At present, when environmental protection is being paid more and more attention, Electric vehicles have received extensive attention from countries all over the world for their advantages in energy safety, environmental protection and long-term development. Electric vehicles have received extensive attention from countries all over the world for their advantages in energy safety, environmental protection and long-term development. With the rapid development of electric vehicles, as the main energy consumer, following the electrical system, the air-conditioning system has become an important factor restricting the power, economy and durability of electric buses. At the same time, compared with the current electric heating PTC method commonly used in electric vehicles, heat pump air conditioners can increase the working range of electric vehicles. Therefore, the application of large-scale energy-saving systems, high-efficiency energy-saving systems, and electric vehicle air-conditioning systems is developed, it is of great significance to the promotion of electric vehicles. This article aims to intelligently study the control system of the electric vehicle air-conditioning heat pump.

In this paper, a kind of efficient air-conditioning control system is proposed. PIC18F458 is adopted as main control unit of the system , which collects all kinds of analog singles such as temperature, humidity and so on, then convert them to digital by the A/D itself. After disposing and calculating each analog signal the system drives corresponding actuator to work to adjust temperature, humidity and cleanness of the air in bus, making passengers satisfied with air quality in bus.

When the ordinary heat pump air conditioning system of a pure electric vehicle runs at ultra-low temperature, the discharge temperature of compressor will be too high and the heating capacity of the system will decay seriously, it will lead to inactivity of the heating system. In order to solve this problem, a modification is put forward, and an experiment is also designed. The experimental results show that in the same conditions, this new heating system increases more than 20% of the heating capacity; when the outside environment temperature is negative 20 degrees, the discharge temperature of compressor is below 60 degrees.
