Analysis of promising directions for the development of technical means for providing a microclimate at livestock farms shows that the most promising are aerial adsorption and catalytic apparatuses. To assess the effectiveness of the application of the developed technological solutions, the modeling of the operation of the recuperative ventilation system of the barn with air-flow adsorption devices was carried out. The results obtained show that the required microclimate in the barn is provided. The required number of heat transfer units for the air fountain heater and heat exchanger, as well as the rational value of the specific capacity of the gasholder, have been determined.
The article is presenting the schematics and design solutions of biofuel engine for mobile woodchipper on the basis of the Stirling engine, working with chip fuel. For the purpose of improvement of the effectiveness of this engine, having variable demand, accumulation of fuel, mechanical and electric energy, and also utilization of thermal emissions are provided.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
