“…When the cooler is ON, it absorbs hot air at a temperature (for example 10 degrees Celsius = 50 degrees Fahrenheit by default) at a constant flow rate (for example 1kg/sec = 3600kg/hr by default). The cool airflow is expressed by the equation (15).…”

In recent years, energy savings in airconditioning (A/C) systems has become one of the hot topics of applied energy towards innovative management and efficient utilization of the operating systems. Achieving thermal comfort with minimum energy consumption is the main concern for innovative designing of an air conditioning system. The A/C system is one of the chief contributors to energy consumption in warm and hot environments. An innovative design of an A/C operating system is essential to satisfy a high thermal performance and maintain the desired thermal comfort level. The aim of this work is to introduce innovative design of an operating system to simulate and experiment the thermal performance of A/C units for two identical houses located in Dhahran area of Saudi Arabia. In this case, the thermal model for both houses has been developed incorporating two different airconditioning operating systems. In the analysis, several physical properties and parameters, such as climate conditions and heat gain/loss, have been taken into account inside the house. Matlab/Simulink software is used to simulate the ON/OFF and the VFD air conditioning controller systems. LabView platform with the data acquisition is utilized for the experimental work to monitor the real time climate and electrical power data.

“…They controlled the HVAC system using a PID controller as a variable speed compressor and a conventional ON/OFF controller. The energy consumption for both controllers was investigated, and the result shows that an excellent energy saving and temperature control can be achieved by using a variable speed compressor [15].…”

“…Other than that, a state feedback control system proposed by Lachhab et al, [5] in regulating the indoor temperature of building services has been able to save more than 30% of energy consumption compared to proportional-integral-derivative (PID) and On-Off control strategies. But, the indoor temperature control via variable speed drive control proposed by Nasution et al, [6] in maximizing the energy-saving and performance of air conditioning system had achieved 45.72% of energy saving.…”

The topic of maintaining thermal comfort efficiency in the heating, ventilation and air conditioning (HVAC) sector has always been tricky due to numerous challenges. The study focused on the challenge of under-actuated zones in non – residential and commercial buildings. The active iris damper with the integration of thermal controller is proposed to control the indoor temperature. Besides, integration of PID control strategy will be a tempting control system in enhancing the thermal performance of the building. Again, the PID controller has proven good compatibility as a primary closed-loop mechanism to maintain a comfortable room temperature. The development of the control system is done through the Arduino platform with LabVIEW as the front panel and data logging platform. The Heuristic tuning method was employed to obtain optimal gains for P, PI and PID controllers. The performance of each controller was tested by observing their ability to maintain steadily at the desired temperature set point. These tests conveyed that the best controller for this application is the PID controller. It reached the desired temperature set point and maintained it even with a temperature disruption. This study indicates that an active iris damper can effectively maintain the thermal comfort performance of indoor environment with the implementation of PID strategy, thus remedying some of the problems faced by centralized air-conditioning systems.
