The utility model discloses a natural gas distribution type energy source utilization system combining liquefied natural gas cold energy utilization. The natural gas distribution type energy source utilization system comprises a liquefied natural gas boosting pump, a liquefied natural gas heat exchanger, a low-temperature turbine expander, a gas turbine and a smoke residual heat lithium bromide cooling and warming machine, wherein an outlet end of the liquefied natural gas boosting pump is communicated with the liquefied natural gas heat exchanger and stretches out from the liquefied natural gas heat exchanger to be communicated with the low-temperature turbine expander; the low-temperature turbine expander is connected with a generator; the low-temperature turbine expander is further communicated with the liquefied natural gas heat exchanger by a pipeline and stretches out from the liquefied natural gas heat exchanger to be communicated with the gas turbine; the gas turbine is connected with the smoke residual heat lithium bromide cooling and warming machine and the generator respectively. The natural gas distribution type energy source utilization system considers that liquefied natural gas contains a lot of usable cold energy and part of the cold energy can be converted into electric energy by recycling so as to obtain a high-quality cold source; meanwhile, cold amount and air conditioning refrigeration can be provided for refrigeration storages with different temperature grades at the same time.
