FIELD: heat power engineering, namely systems for heating water for needs of bath house - laundry services, particularly in coal production mines. ^ SUBSTANCE: heat transfer agent and heated medium circulate in heat exchange circuits of heat pump. Sewage water of bath house-laundry service of coal mine are used, for example as heat transfer agent. Before draining sewage water into canalization777 it is preliminarily accumulated in heat-insulated vessel and then it is subjected to multiple circulation in loop of evaporator of heat pump until temperature of heat transfer agent achieves value 5 - 10 C. ^ EFFECT: rational effective process of recovering heat of small volume of sewage water with relatively high residual temperature. ^ 1 dwg |
