This project is based on the design and construction of an industrial air conditioning system for the improvement of the working thermal comfort of workers that for various reasons there is the trend of the increase in body temperature are these by machines, equipment or the same work activities, which affects the productive performance and possible health risks. During development, the selection of mechanical equipment such as the fan, water pump, ventilation transport ducts is studied with high rates of energy efficiency. In the light of the above, the environmental economic partner alternative is chosen to implement the evaporative conditioning system, conducive to working in open places to lower the temperature by labor and technology installed in the production areas, as well as the extraction of fumes derived from production processes. The importance of the evaporative conditioning system is to derive the appropriate mechanisms to take advantage of the surface heat transfer of a panel and copper and aluminum coil using water, and thus take advantage of its temperature differential reaching 25oC, with an average humidity of 66% and energy consumption of 0.29 KW/h.
The high family consumption of chocolates and cocoa powders with a high content of sugars and saturated fats, and on the contrary a very low content of cocoa paste is a problem. The objective was to recover the ancestral knowledge in the elaboration and conservation of the traditional Manabi cocoa paste. The experimental method was used for the elaboration and conservation of cocoa paste in clay pots with dried guineo leaves, in glass jars, at room temperature, and in refrigeration. Through the technique of interviewing 10 peasant women from the rural area of Chone, the way of elaboration and conservation of the cocoa ball was known. The main results: increase of the useful life of the cocoa ball wrapped in dried guinean leaves and stored in clay pots at room temperature, due to the decrease in humidity up to 180 days. As conclusions: little use of ancestral knowledge in the elaboration and conservation of traditional Manabí cocoa paste, unlike the consumption of refined chocolates with low cocoa content.
The limited use of natural resources that are possessed, which implies endemic flora (shrubs, herbs, etc.) and production waste ( leaf litter, various plant fibers, cattle manure, poultry, etc.), which are stacked for later burning and consequently causing pollution to the environment, are some of the problems that are generated at the farm level. The objective of the research was to generate biofuel derived from the mixture of methanol, sodium hydroxide and fig oil in the Mis 2 Principitos del Comuna El Limón farm, Portoviejo canton. Within the methodology to produce biodiesel or biofuel through the transesterification process, castor oil obtained from the fig seed, methanol (methyl alcohol) and potassium hydroxide (KOH) (acid or catalyst) were used. By means of the transesterification in which 0.001 m3 of castor oil, 0.0001 m3 of methanol and 0.01 Kg of potassium hydroxide were used under conditions of an approximate temperature of 60 ° C and 40 rpm of agitation in the stirrer plate, it resulted in 0.001 m3 of biodiesel. Biodiesel can be generated from fig or castor oil, taking advantage of a biomass energy source, which can be used in pump engines for irrigation in farms.
The study aimed to characterize the therapeutic benefits of honey and other beehive products to determine the feasibility of rural beekeeping production; The research was carried out in 30 apiaries of peasant communities in 7 cantons of the province of Manabí, namely: Portoviejo, Rocafuerte, Bolívar, Santa Ana, Montecristi, Chone and Pichincha; an intentional sampling was applied, the qualitative-quantitative approach, a non-experimental descriptive design; For data collection, the survey technique was applied to beekeepers, the analytical method to perform the analysis of the results of the applied survey. As a result of the bibliographic review, multiple therapeutic benefits of honey, pollen, propolis, apitoxin, royal jelly were obtained, among which their immunomodulatory, antiviral, antimicrobial, antitumor, anti-inflammatory, healing properties, among others specific to each product, stand out. The feasibility of the rural beekeeping activity was determined through the cost-benefit analysis whose indicator of 1.95 showed that it is profitable. It was concluded that honey and other products from the hive contribute to preventing, strengthening, and improving the ability to respond to various diseases that afflict human beings, and as a productive activity, it is feasible to implement it to generate income for families.
The appropriate use of energy is vital for the sustainable development of society in the different productive areas such as the industrial, commercial and domestic sectors, in this sense the machines must use suitable materials tending to reduce the contamination of water sources and soil, emission of carbon dioxide into the atmosphere due to energy consumption. In this context, the objective of the study focused on designing an air conditioning system based on the carbon footprint; life cycle analysis (LCA) and eco-designs were applied as a methodology, allowing to identify the categorization of the contaminant and its level of environmental impact, from the extraction of resources, manufacturing, distribution, use and final disposal. It was possible to evaluate the environmental impact referring to the functional unit of a split-type air conditioning system of 12,000 BTU of cooling capacity, obtaining as a result the carbon footprint with an annual carbon dioxide quantification of 722.8 tons of carbon dioxide. carbon (CO2), significantly representing the intensive use of the system and, on the other hand, the energy required for the manufacturing process of the refrigerant gas hydrofluorocarbons (HFC) R410 A.
