The invention relates to a method for transporting the energy of a gas-liquid two-phase flow and belongs to the technical field of energy transportation. An evaporator and a condenser which are both heat exchangers are respectively arranged at a place supplying cold energy and heat energy and at a place using cold energy and heat energy; the evaporator and the condenser are organically connected into a whole through a gas-liquid two-phase flow main pipe, a two-phase flow distributor, a two-phase flow equalizing pipe, a main liquid return pipe, a liquid storage tank, a cycling solution pump, a solution transport pipe, a liquid separator and a liquid equalizing pipe to form an energy transport system of gas-liquid two-phase flow; heat energy carrying working media from the evaporator to the condenser is in a state of the gas-liquid two-phase flow; heat energy carrying working media from a heating section to a cooling section is in a liquid-phase state; the energy transport system of gas-liquid two-phase flow is different from a heat pipe energy transport system; heat energy carrying working media from the evaporator to the condenser is in a gas-phase state, thus the method for transporting the energy of the gas-liquid two-phase flow is formed; and when the circulation is repeated, the cold energy and the heat energy can be transported continuously. The invention has the advantages of reliable transport principle, simple equipment, high heat efficiency and significant economic and social benefits.
