“…Note that the curves are nearly parallel, with highs of around 40 C (2 August), 35 C (11 July) and 30 C (13 June). A study conducted by Izquierdo et al [8] reported similar findings. The indoor dry bulb temperature, pur suant to the Spanish Regulations on Thermal Facilities in Buildings [9], was assumed to be 25 C.…”

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.

“…Consequently, the performance of the chiller gets worse. These results are similar to others [19,20], where the relation between COP, power, and outdoor temperature and the slope of the trend lines is the same.…”

This paper describes a solar absorption cooling installation located at the University of Zaragoza (Spain). The installation is based on the performance of an absorption chiller. The solar cooling system consists of 37,5 m 2 of flat plate collector, a 4.5 kW, singleeffect LiBr-H 2 O absorption chiller, and a dry cooling tower. The installation provides cooling to a gymnasium belonging to the sports center of the university. To carry out the installation analysis, the system was continuously monitored. In 2007, 2008 and 2009, several studies have been performed in order to analyze the full system operation. The measured data showed the strong influence of the cooling water temperature and the generator driving temperature on the COP. Due to the experimental evidence of the influence of the cooling water temperature, a new heat rejection system based on a geothermal heat sink has been installed and studied.

“…by converting the kinetic energy at the outer radius of the vessel into pressure. Further information on the Rotartica chiller has been reported in [10]. Simplified scheme of the installation [8] In the proposed air conditioning system, the electricity consumption is due to the Rotartica machine itself (400 W), the cooling tower (370 W) and the pumps on the heat rejection circuit and the generator circuit (200 W).…”
