Low-loss prime mover and working method

Abstract

The invention belongs to a prime mover, and particularly relates to a low-loss prime mover and a working method. The low-loss prime mover comprises an evaporator, a machine body and an energy body, wherein rolling bodies are arranged on the machine body or the energy body; the outer wall of the energy body is connected with the inner wall of the machine body through the rolling bodies, and the energy body and the machine body achieve rolling displacement through the rolling bodies; and a cavity is formed between the bottom of the energy body and the inner wall of the machine body. The evaporator continuously absorbs heat to evaporate a liquid working medium to push the energy body to move upwards to do work till the upper limit stroke is reached, and when the environment temperature meetsthe liquefaction temperature, the energy body moves downwards due to dead weight to compress a gaseous working medium to complete liquefaction, and the energy body is connected with the machine body through the rolling bodies in a rolling manner, so that frictional resistance between the energy body and the inner wall of the machine body is greatly reduced, unnecessary energy loss is avoided, andthe low-loss prime mover is simple in overall structure, low in cost, stable in performance and high in efficiency, and has positive economic value.

Description

technical field [0001] The invention belongs to a prime mover, and in particular relates to a low-loss 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 ab...

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
