Study On The Natural Cool Resource Air Conditioning Control System Based On Ⅵ

In north China, the cold winter, which is pretty long, and the hot summer form bright contrast, besides,Each summer, air conditioning environmental regulation, fresh agricultural and sideline products fresh-keeping aspects need to use a lot of energy. Facing the increasingly of shortage of the energy crisis, people began trying to seek more clean new renewable energy to replace the existing dwindling subject non-renewable resources. In the northeast of China the long and cold winter, rich in natural cold resources. This design is based on making use of the natural cooling air conditioning system to adjust temp meter resources environment.This paper mainly studies the main content as follows:1)This paper studies through inter-external natural resources and environment regulation of cold theory and experience, combining the northern climatic characteristics, designed a set of utilization of natural resources of cold cool humidifying device is designed for LabVIEW software development platform for the air conditioning automatic control system environment.2) Analyzed the virtual instrument compared with traditional instruments of advantages, use acquisition card with a remote output module, sensor technology, computer technology and virtual instrument technology and database technology organically, and air conditioning system of measurement and control system management software design. Using acquisition module implements air-conditioning in environmental parameters in the real-time data acquisition, display, storage, inquires the functions, and with the help of computer of serial technology and distal analog output module, realize the air conditioning in the switch quantity of actuators control. Using the LabVIEW Web publishing tools, realize the air conditioning control system of networked remote interface control, the air conditioning control system interface issued in IE page, and makes the distance client can be realized through IE browser of site monitoring and control.3) The entire air conditioning system carries on the comprehensive analysis and routes of reasonable layout and design the bus control circuit, actuators circuit and control circuit. 4) Analyses of temperature, humidity, air conditioning CO₂ concentration environmental factors such as range change and coupling relationship, establish the air conditioning control model of the whole system, and based on this, choose corresponding sensors and actuators as system hardware components of air-condition, internal environment parameters are collected and regulation, for the whole control system and equipment debugging, and debugging results are analyzed, by test and data show that the control operation system stability, each function is normal, software graphical interface abundantly. Realize the air conditioning1.5℃ 25℃between temperature, humidity 30%¹00%, CO₂concentration 200ppm⁴000ppm adjustable scope.
