The diffusion-absorption refrigeration (DAR) cycle has characteristics as the use of three working fluids and a low COP. In this work, an analytical and experimental investigation of a household refrigerator operating under a H20-NH3-H2DAR cycle is performed.

Although many safety measures adopted by governments around the world helps to reduce such accidents, the biggest risk factor still persists, which is precisely human driving.

The objective is to study the climatic variability of the elements, maximum temperature, minimum temperature, average temperature, thermal amplitude, relative humidity, wind intensity, evapotranspiration, evaporation as well as to evaluate the estimate of the climatological water balance for the municipality of Camalaú, Paraíba. Monthly and annual precipitation data, referring to the 52-year period of observed data (1962-2014), from which graphs of annual variations, monthly and seasonal averages of precipitation were obtained to satisfactorily represent the region's rainfall regime.
