“…Moreover, according to Shuangquan Shao et al [19], it is one of the best options of regulation. A number of authors have conducted experimental studies on variable flow compressor efficiency, such us Tassou and Qureshi with reciprocating compressors in refrigeration facilities [20], or Aprea et al with scroll compressors [21]. For the purpose of this study, it is supposed that the AC units have variable speed regulation, being the efficiency due to part load operation defined by Eq, (25).…”

a b s t r a c tAn understanding of electricity consumption due to residential air conditioning (AC) may improve production and environmental impact strategy design. This article reports on a study of peak and seasonal electricity consumption for residential air conditioning in the region of Madrid, Spain. Consumption was assessed by simulating the operation of AC units at the outdoor summer temperature characteristics of central Spain. AC unit performance when operating under part load conditions in keeping with weather conditions was also studied to find cooling demand and energy efficiency. Like wise final electricity consumption was computed and used to calculate energy costs and greenhouse gas emissions (GHGs). Cooling demand, when family holidays outside the region were factored into the calculations, came to 1.46 Â 10 9 kWh. Associated seasonal electricity demand was 617 Â 10 6 kWh and seasonal performance of AC units around 2.4. Electricity consumption in the whole region was observed to peak on 30 June 2008 at 5.44 Â 10 6 kW, being the load attributable to residential AC 1.79 Â 10 6 kW, resulting about 33% of the total peak consumption. The seasonal cost per household was about V156 and the total equivalent warming impact was 572 Â 10 3 t CO 2 . The method proposed can be adapted for use in other regions.

“…They concluded that significant saving in energy consumption could be achieved but they gave no results concerning dynamic tracking of the variables of interest and superheat was controlled conventionally. In later work [11] they investigated a similar fuzzy control algorithm applied to the capacity control of a reverse cycle heat pump (operating as an air-source heat pump in winter and an air-sink chiller in summer). Again coupled control over superheat is not considered.…”

“…The rotational speed control of the scroll compressor used in a cooling loop has been tested experimentally by Aprea et al (2006Aprea et al ( , 2008. It was noticed that by varying the rotational speed of the compressor to match the cooling load required, the consumption of electricity was decreased compared to the energy consumption of the oneoff controlled compressor.…”
