LabVIEW is an innovative product of National Instruments Corporation which is a virtual instrument development environment marked by graphical software programming method and the integrated development environment. This paper focuses on the airconditioningsystem of venue and the audience area in a university gymnasium, and then draw the outline of the various parameters to measure branch of the monitoring and control, and the choice of components of the type of virtual air conditioning control system hardware, while uses LabVIEW software platform to develop the software of virtual air-conditioningcontrolsystem, Finally commissioning and raise the entire virtual air conditioning control system. A necessary information database can use computer establishing virtual air conditioning control system for airconditioning units. The temperature and humidity of air supply, temperature and humidity indoor airconditioning room, temperature and humidity outdoor air supply speed, return air and fresh air is can be measured, comprehensive and timely through the telemetry system measurement. In this way, we can keep pace with The Times of the airconditioningsystem, so as to guide the operating conditions of cold and heat sources plan more effectively run the efficiency.

This paper outlines the methodology of designing and developing a smart controlsystem for controlling light, airconditioning and ceiling fans in a room. This system considers the requirements of the users appropriately and makes a comfort zone for the users. An android application with a user friendly Graphical Interface, which is easy to communicate with the smart controlsystem, has been developed. The application is connected with the controlsystem through Wi-Fi across a cloud network and it can respond quickly. RGB LED panel light system that controls the color, color temperature and luminance was designed by considering the requirements of the instances and lighting conditions. Although there are RGB LED panel lights available, there are no systems defined for the activity based color modes. An IR Remote module controller system was built for controlling inverter type air conditioners by giving commands from a smart phone application. This system considers the mean value of the preferences of many users to control the airconditioningsystem. The running mode of the air conditioner is chosen from the data given through the application by many users in a same place. Although the inverter type air conditioners continuously regulate the temperatures, the fan does not do it. Because of this problem, a ceiling fan controlling system with two modes, automatic and manual, was designed. Automatic mode utilizes the users skin moisture related hybrid system to set the room temperature. Manual mode works according to the suggestions given by the crowd just as the airconditioningsystem. This airconditioning and ceiling fan controlsystem that works according to the suggestions of crowd is better than the individual preference system using a conventional remote controller.

This paper outlines the methodology of designing and implementation of a solar powered system which can be used to make a human comfort zone during day time without using battery backup but with the use of Supercapacitors. Basically, major converter losses are reduced in this system. In acquiring a highly efficient power supply, the charge controller plays an important role. When a DC microgrid powers DC loads based on a renewable source such as a PV system;energy storage becomes mandatory due to fluctuating nature of the source. Localized DC-energy storage within DC-DC converters could address this requirement. A variation of supercapacitor assisted regulators could provide localized energy storage with low-noise and fast transient response [1]. 12 V LED lights will be powered from this system. LEDs can be powered directly via a supercapacitor bank from the regulated Photovoltaic energy. In the case of Inverter type air Conditioner, in order to overcome converter losses, the DC Bus inside it should be accessed. Typically, DC Bus voltage inside the Variable Frequency Drive (VFD) is 1.414 times the supply voltage. Hence DC-DC Converters are used to power up the inside circuitry of the Inverter air Conditioner from the solar panel. In order to optimize the energy usage and reduce electricity consumption, light dimming and air conditioning control systems were added to control the light intensity and switching of the air conditioner.
