Embodiment Construction
[0017] Such as figure 1 As shown, a low-temperature liquid / gas energy conversion heat engine includes a body 20 . The body 20 is an airtight casing, and there is a motor 1 outside the body 20 . The starter 1 is an electric motor powered by an AC power source or a battery 18 . The starter 1 is connected with the crankshaft 2 through a reduction mechanism. One end of the crankshaft 2 is connected to the generator 16 outside the body 20, and the electricity generated by the generator 16 is used to supply power to the load 17 (of course, the crankshaft 2 can also directly output power to drive the load). The other end of crankshaft 2 links to each other with the piston rod 29 of a pair of parallel cylinders 3,4 in body 20 (can select many pairs according to the different cylinders of power, for the sake of simplification of explanation, present embodiment only takes a pair as example to illustrate). The phases of the two cylinders are complementary, with a phase difference of ...

The present invention relates to a low-temperature liquid / gas energy conversion heat engine. It contains at least a cylinder capable of utilizing gasification expansion of working media of methane and others to apply work, on the piston rod of said cylinder a crankshaft is connected, the outer end of said crankshaft is connected with power generator and / or other load. In the top portion of cylinder are set a liquid working medium inlet, a heat-carrying fluid inlet and a fluid outlet which are respectively connected with liquid working medium temperature control liquid storage tank, heat-carrying fluid tank for exciting working medium liquid / gas conversion and mixed liquid separation tank by means of respective control valve. On the separation tank a working medium liquid outlet and a heat-carrying fluid outlet are set, the working medium liquid outlet is connected with liquid storage tank, and the heat-carrying fluid outlet is connected with heat-carrying fluid tank by means of heat exchanger and / or air conditioner. Said invention also provides its concrete working principle and its extensive application field.
Description
technical field [0001] The invention relates to the technical fields of energy and power. Especially a kind of utilization methane, ethylene (C 2 h 4 ), nitric oxide, freon R-14, krypton and other substances can be converted into liquid / gas at low temperature (critical point 9.5 ℃, ethylene (C 2 h 4 )) The characteristics of thermal power machinery for energy conversion (power generation). Background technique [0002] Energy shortage has become a restrictive factor for social and economic development, so people are constantly exploring and developing new energy utilization methods and equipment. Low temperature thermal energy conversion technology has been paid attention to by people. The traditional low-temperature thermal energy conversion is carried out by using temperature difference. Due to the small temperature difference and low efficiency, the traditional technology itself consumes a lot of energy, the cooling equipment is huge, the investment cost is high and ...
