FIELD: thermal engineering; heat, power, and refrigeration cogeneration. SUBSTANCE: liquefied natural gas is conveyed from heat-insulated tank 1 by means of pump 3 over fuel feed line 2 to control valve 4 wherefrom it is passed to refrigeration chamber 5; in the latter it cools down refrigerant of air conditioning system; in the process it evaporates and is heated at high pressure. Then it is heated to high temperature in heater 6 and passed to turbine 7 wherein gas expansion enables generation of additional power in generator 8. Flue gases escaping prom boiler 10 flow over line 11 through heater 6. Air conditioning system incorporating on-line air conditioner 12 and refrigerant closed loop 13 with heat-transfer apparatus mounted in chamber 5 is designed for air cooling and conditioning within boiler house. . EFFECT: enhanced capacity of system; provision for additional power generation and air conditioning inside boiler units. 1 cl, 1 dwg
