FIELD: device for independent heat and cold supply to rooms in buildings of residential, cultural and educational, commercial and administrative and other destinations with the use of renewable low-potential heat sources from the environment (upper soil layers at a depth of 100 to 200 m) and heat disposals of ventilating air recovered after accumulation of the soil and air heat with the use of thermocompressors. ^ SUBSTANCE: the device for power supply to rooms with the use of low-potential power carriers has a system of gathering and recovery of soil heat including to the heat supply circulation network with the pipe-lines of supply of cold and hot water through water accumulators with peak finish heaters and condensers of the main and additional thermocompressors, the system includes the main circuit of circulation of the low-potential heat-transfer agent passing through the heat exchangers installed in the water wells, and the evaporator of the main thermocompressor, as well as a system of accumulation and recovery of heat removed from the ventilating air rooms including an additional circuit of circulation of the low-potential heat-transfer agent passing through a water-to-air heat exchanger, whose air side is connected to an air heater and a fan of feed of removed air, and the water side is connected to the inlet and outlet of the evaporator of the additional thermocompressor through crosspieces, and coupled through other crosspieces to the outlets of the heat exchangers in the water wells for transfer of heat collected at the air side of the heat exchanger, or for finish heating of the low-potential heat-transfer agent in the main circulating circuit before the heat-transfer agent is fed to the evaporator of the main thermocompressor, with the additional thermocompressor disconnected trough the crosspieces from the water-to-air heat exchanger, or for recovery of the heating condition of the water wells cooled at accumulation of the soil heat, the outlets and inlets of the heat exchangers in the water wells are coupled to the inlet and outlet of the evaporator of the main thermocompressor through the crosspieces, and the water side of the water-to-air heat exchanger is provided at the outlet with a fork for separation of the flow of the low-potential heat-transfer agent into the direct and reverse ones, to the heat-exchanger, branch coupled to the flow governor of the heat-transfer agent in the direct and reverse branches, and the temperature-sensitive element of the heat-transfer agent installed at the heat exchanger outlet, before the fork. ^ EFFECT: expanded technological functions of the device due to provision of the possibility of correction of the heat-transfer agent temperature at the outlet from the device before it is fed to the thermocompressor during the heating season and influence on the temperature condition of the wells of heat collection in the interheating periods with the aim of stabilization of the transfer ratio of the heat-transfer agent and enhancement of its season average value with due account made for different geological prerequisites for device operation (including the range of the initial temperatures of the soil upper layers: 5-8 C), as well as provision of the possibility of use of the potential of the cooled wells for cooling of rooms, thus obtaining an additional contribution to the energy fluxes supplied to the consumer increasing the utilization factor of energy fluxes. ^ 3 cl, 4 dwg |
