DEVICE FOR PRODUCING ENERGY OF WATER-ICE PHASE TRANSITION Russian patent published in 2022 - IPC F24D15/00 F25C1/00 F25C1/12 

FIELD: agriculture.

SUBSTANCE: invention relates to refrigeration equipment; it can be used in agriculture, namely at enterprises of the agro-industrial complex and in thermal accumulator systems, as well as for heating industrial and infrastructure facilities. The technical objective of the present invention is to use the energy of a water-ice phase transition for heating agricultural facilities, at enterprises of the agro-industrial complex and in thermal accumulator systems, as well as for heating industrial and infrastructure facilities. A device contains tank 1, circulation pumps 9, 13, 17, evaporator 7, heat exchanger 5, compressor 18, condenser 19, throttle valve 20, solar collector 11 and device for moving ice 15. Tank 1 is divided by partitions 2 and 3 with thermal insulation material into three tanks: tank 4 for water with heat exchanger 5, tank 6 for antifreeze with evaporator 7 and tank 8 for collecting and melting ice, which are connected by tubes to circulation pumps for circulating antifreeze from tank 6 for antifreeze with evaporator 7 into a silicone tube of tank 4 for water with heat exchanger 5, for circulating a water-ice mixture from tank 8 for collecting and melting ice into tank 4 for water with heat exchanger 5, for circulating cold tap water into tank 8 for collecting and melting ice. In tank 6 for antifreeze with evaporator 7, block for electrophysical action 21 is installed, which lowers the freezing point of antifreeze, increasing the amount of energy received from the water-ice phase transition. Evaporator 7 is made in the form of a coil-type tube. The heat exchanger 5 is made in the form of a flexible corrugated silicone tube of a coil type with a metal insert, on the surface of which ice is formed, and antifreeze is circulated inside it to transfer the energy of the water-ice phase transition to consumer heat exchanger 16. To separate ice from the surface of the tube, piezoelectric ultrasound emitter 14 is provided, which, using ice moving device 15, is moved into tank 8 for collecting and melting ice, in which heater 10 is installed connected to solar collector 11.

EFFECT: as a result of the use of the invention, it becomes possible to obtain the energy of the water-ice phase transition and use it for heating agricultural facilities, at enterprises of the agro-industrial complex and in thermal accumulator systems, as well as for heating industrial and infrastructure facilities.
