New methodological approach to calculations for design of energy-saving device for heating water intended for livestock watering

Abstract

Relevance. The development and use of new tools and technologies aimed at energy saving in agriculture has been and remains an urgent task. The use of non-traditional and renewable energy sources has become very popular. An advanced role in this direction is acquired by the use of heat released by cattle.Methods. It is assumed that due to the free heat, which is directed to the disposal of the livestock premises, heating will occur, for which a new device for heating water has been developed. Based on the results of calculations and observations, it was decided that the device for water heating will be placed in the place where the air temperature in the livestock premises reaches maximum values. There are a number of issues that need to be solved. One of them is an important part of the design of a new heating device — this is the calculation of its constructive parameters.Results. It is necessary to take into account many factors that affect the heat generation of cows, their drinking conditions, possibility of the installation of the heat exchanger to affect the ventilation in premises, its heating capacity. The calculation of these parameters will make it possible to evaluate in real conditions of use of water heating device, working due to the release of heat from cattle. Its use will reduce the consumption of electric energy, which is used to heat water intended for cows.
