A CASE STUDY COMPUTATIONAL ANALYSIS OF LITHIUM BROMIDE SOLUTION FOR HOUSEHOLD ABSORPTION HEAT TRANSFORMER

Abstract

Steam compression installations operating from electric energy are widely used in the world for air conditioning. This type of installation has a number of disadvantages, and therefore a new air conditioning installation has been proposed. Ab-sorption heat transformer is an air conditioning and hot water installation based on the principle of an absorption heat pump. The installation can also be used for heating. The installation is able to use renewable energy sources or utilize the heat of exhaust gases as heat sources: for example, from a heating boiler with a temperature of up to 115 °C. The practical significance of the installation lies in resource conservation and environmental friendliness. The use of this installation will ultimately reduce the consumption of primary fuel and reduce the negative impact on the environ-ment. The paper considers the possibility of using a lithium bromide solution in an absorption heat transformer for resi-dential premises. For this purpose, a number of calculations were carried out, according to the calculation method of ab-sorption refrigerating lithium bromide machines. As a result of the calculations, it was established that the use of lithium bromide solution is satisfactory for use in a household heat absorption transformer. However, in order to achieve greater efficiency, the installation scheme requires refinement.
