Prime mover and working method

Abstract

The invention belongs to a prime mover, and particularly relates to a prime mover and a working method. The prime mover comprises an evaporator, a machine body and an energy body, wherein the energy body is arranged in the machine body in a sliding mode; a closed cavity is formed between the bottom of the energy body and the inner wall of the machine body; the evaporator communicates with the cavity and continuously absorbs heat to evaporate a liquid working medium, and the volume of the working medium expands due to evaporation so as to push the energy body to move upwards to do work until the upper limit stroke; and when the ambient temperature is lower than the evaporation temperature, the energy body moves downwards to compress the gaseous working medium due to self weight to completethe liquefaction. According to the prime mover and the working method, the evaporator evaporates the liquid working medium, the volume expansion pushes the energy body to move upwards to do work, andthe mechanical energy is output; when the ambient temperature meets the set value of the liquefaction stroke, the gaseous working medium is compressed by the self weight of the energy body to carry out the liquefaction stroke; the whole working stroke and liquefaction stroke do not need other auxiliary equipment, so that unnecessary energy loss is avoided; and the whole structure is simple, the cost is low, the performance is stable, the efficiency is high, and the positive economic value is realized.

Description

technical field [0001] The invention belongs to a prime mover, and in particular relates to a prime mover and a work method. Background technique [0002] Prime mover refers to all machinery that uses energy to generate motive force. It is the main source of power required in the fields of modern production and life. [0003] At present, in the equipment that converts air heat energy into mechanical energy, the working fluid with low evaporation temperature is generally used to absorb heat and expand to do work. However, this kind of evaporation from liquid to gas requires special mechanical equipment to complete, and the gaseous working fluid returns to liquid. It also requires Use other equipment to compress the gaseous working medium or increase the exhaust pressure to complete it. This method will reduce the working pressure difference and reduce the work. For example, the gaseous working medium is compressed into a liquid state by a compression machine. The above two s...

Problems solved by technology

In this invention, it is necessary to depressurize through the expansion mechanism 15 and evaporate through the first evaporator 16. After the evaporation occurs and expands to perform work on the rotary vane power machine 17, it is then compressed back to the first condenser 13 through the generating state working fluid compressor 12. Circulation, in the circulation path of doing work, the evaporation and liquefaction of the refrigerant requires the expansion mechanism and the generating gas working medium compressor 12 respectively, which increases the cost and consumes a large amount of kinetic energy or electric energy, resulting in a waste of energy and cannot generate economic benefits. At the same time, with the design of this kind of circulation pipeline, the refrigerant flow path is long, and part of the energy will be lost on the way, which will also cause energy loss
