Abstract
On the territory of the Russian Federation, there are a large number of geothermal heat sources with a low, no more than 50 °C, temperature potential, on the basis of which it is possible to create environmentally friendly heat supply systems using heat pumps. Efficiency assessments were made for the use of boost-type absorption heat pumps for these purposes, in which a geothermal or technogenic heat source with a temperature of 40…45 °C is theoretically capable of providing heating of the heat carrier of the heat supply system to 55…63 °C in winter at specific costs of electrical energy for the operation of circulation pumps, automation and control systems - not more than 1.0 % of their useful heat output. The ambient air with negative temperatures sufficient to lower the temperature of the coolant to minus 4°C was considered as a cooling medium. The range of calculated values of the heat transformation coefficients for the considered conditions was α = 0.46…0.47. An analysis of the comparative advantages and disadvantages of using aqueous solutions of LiBr and LiCl salts as working bodies was carried out, on the basis of which the prospects for using the LiCl salt aqueous solutions in absorption heat pumps of a boosting type were shown.
