Abstract
In recent years, energy savings in air-conditioning (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 air-conditioning 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.
Highlights
Energy savings and efficient utilization of the cooling systems require innovative design of the thermal units that meets the demand with reasonable comfort levels
One HVAC system operates by an ON/OFF cycle and the other HVAC system operates by using a variable speed driver (VFD)
The simulation results are produced for ON/OFF and Variable Frequency Drive (VFD) air conditioning units
Summary
Energy savings and efficient utilization of the cooling systems require innovative design of the thermal units that meets the demand with reasonable comfort levels. To evaluate the energy consumptions used by the space-conditioning, thermal modeling and simulation of the house must be developed and two types of HVAC system operations will be presented. A simple-physically-based model is used to simulate heating and electric energy consumption throughout the year for domestic HVAC systems They reported that the best energy saving strategy for the HVAC system could be developed through energy modeling to evaluate the effects of envelope design on energy consumption of air conditioners [14]. The experimental set-up with Lab-View based data acquisition monitoring and measurement system is developed while the thermal model and simulation of the house is carried out incorporating different types of A/C system controller (ON/OFF, VFD) units. The superimposed graph displayed in Figure 6.a shows the instantaneous values of four temperatures and pressure with time and Figure 6.b displays the instantaneous values (peak to peak) of line voltage with corresponding RMS values
