Based on dynamic thermal simulations with the EnergyPlus software, an experimental module of a rural dwelling is proposed for the village of Imata, Peru, at 4519 meters above sea level, with severe climatic conditions of very low temperatures. Simulations were carried out for five module configurations, successively adding bioclimatic components, such as improvements in the insulation of the enclosure, skylight and attached greenhouse. For the month with the lowest temperatures, the average temperature in the best configuration module is 11 °C higher than the average temperature in the module corresponding to typical Imata houses. The minimum average night temperature is 18.4 °C higher than the corresponding outside temperature (- 4 °C). To maintain a temperature of 16.3 °C inside the module (adaptive model), on annual average, a daily energy of 12 kWh is required for the typical module, and 1 kWh for the best design.

The design and evaluation of several configurations of evaporative cooling systems for air conditioning of a dwelling for low-income sectors in Mexicali, Mexico using simulation with TRNSYS 16.A is presented in this paper. The configurations studied include direct as well as indirect evaporative cooling with heat exchange and also systems with solid desiccant. The main rating parameters to classify the different configurations are the internal comfort conditions, the efficiency and the number of required equipments. The results show that the best configuration is one that includes a heat exchanger that pre-cools the air inlet stream with a cooling stream delivered by air coming from the dwell, but there is a small fraction of the time during the day that comfort is not met. If thermal comfort is to be met during the whole day, solid desiccant systems are the best choice. [ABSTRACT FROM AUTHOR]
