“…On the other hand, it is well established from experimental study in [9], that the compressor ON/OFF cycle causes significant amount of efficiency and capacity loss. In addition, it is experimentally found that efficiency loss of the system is 9% and the capacity loss is 11% due to compressor motor ON/OFF cycling.…”

“…The energy demand in correspondence has grown at a much higher pace of approximately 5-8% per year [8]. Moreover, A/C systems are considered to be the major energy consumptions in the residential area in KSA and it is accounted for approximately 60% [9][10]. The significant focus in evaluating the performance of HVAC systems is ensuring the thermal comfort and reducing the energy consumption.…”

“…Since the main door opening influences the energy consumption, duration of the house main door opening becomes critical for air-conditioning (A/C) unit operation. Although the effect of the door air flow on A/C energy consumption was studies previously [9][10][11][12][13][14][15], the temporal effects of the cooling load demand on energy consumption were not included in the studies. The temporal demands for the domestic cooling load can occur when the house door is frequently kept open in buildings.…”

Varying cooling load requirements in HVAC system become a major concern to many consumers because of the additional cost of electricity. The cooling load variation of HVAC system usually occurs when the domestic house door is frequently kept open for prolonged durations, which is particularly important in hot seasons. The present study, addresses a comparison of energy consumption due to the thermal disturbance during domestic house door keep opened for various duration when the Variable Frequency Driver (VFD) and ON/OFF controllers are installed in HVAC system. The experiments are carried out in two identical houses during six warm days in a hot season where the outdoor temperatures have similar patterns throughout the days. The energy response of HVAC system is analysed incorporating the thermal and the electricity consumption data because of the change of the indoor temperature during opening of the house main door. The cost analysis is carried out and it is extended to include several repeats of door opening durations. It is the first time demonstrated that the energy consumption for HVAC system increases dramatically when the house main door is kept opened for several times in a day. The energy consumption and additional cost increase significantly for the case when the period of the main door opening is extended. In this case, VFD A/C controller unit achieves more energy savings than that of ON/OFF A/C controller unit.

“…On the other hand, many residential areas around the world are characterized by hot and humid atmosphere, such as in the Arabian Gulf, Africa, S America, S. Asia, and part of USA. For example, the primary energy consumption in Saudi Arabia is the HVAC system which accounts for about 60% of the energy used in the houses [7]. Space-conditioning has gone on the rise throughout the Kingdom of Saudi Arabia (KSA) and also consumption of more energy has increased due to the severe hot temperature, high humidity, and dust storms.…”

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.

This paper presents an investigation into the viability of 'fabric first' intelligent architectural design measures, in combination with a hybrid cooling system (HCS). The specific aim is to displace AC and reduce CO2, while maintaining thermal comfort, in a typical housing block in KSA. The results of thermal modelling and prototype field trials suggest that passive design measures (PDMs) combined with night radiant cooling and supply ventilation via ground pipes, can negate the requirement for a standard AC system. Such a strategy may also have a remarkably short payback period when energy savings, in use, are set against the additional capital costs associated with improved building fabric performance. Practical application This study suggests that a significant proportion of AC cooling energy can be displaced by improving building fabric performance in combination with supply ventilation via ground pipes. As radiometer readings fell as low as 2.8°C when the night sky is clear, roof mounted high emissivity hydronic radiant panels can also provide a significant opportunity for additional heat flushing. In hybrid combination, these strategies have the potential to lower the carbon footprint of a typical housing block in KSA by over 80% and these measures and strategies will be equally applicable and costeffective in all geographic regions of the world where cooling loads represent the predominant domestic energy use.
