Problems solved by technology

[0005] The purpose of the present invention is to provide a zero-leakage refrigerator. The present invention is to overcome the fact that the existing gas-liquid phase change compression refrigerator has a cooling performance of only 2.0 to 3.0, which wastes a lot of energy, and its working medium has harmful effects on the human body and the atmospheric environment. Serious pollution problems, and existing Stirling refrigerators still have low power / weight ratio, and difficult sealing to achieve zero leakage, etc.

Abstract

The invention discloses a zero-leakage type refrigerator and relates to the technical field of thermal energy conversion. The zero-leakage type refrigerator is designed for solving the problems that the refrigeration effectiveness of the existing gas-liquid phase change type compression refrigeration mechanism is only 2.0-3.0, a large amount of energy is wasted, a working medium can cause serious pollution problem to human bodies and atmosphere environment, the existing Stirling refrigerator also has the problems of small power / weight ration, difficulty in sealing and incapability of realizing zero leakage and the like. An air guide cylinder cavity is communicated with the upper part of a compression cylinder cavity for forming a closed cavity, the closed cavity is connected with a ventilation valve to the outside, the conduction initial point of the ventilation valve is that a compression piston moves to 10 degrees before the top end of the left side of the compression cylinder cavity to 45 degrees after the top end when a crankshaft in a flywheel crankshaft assembly rotates, the conduction angle of the ventilation valve is 5 degrees to 30 degrees, and all the movable sealing parts and a ventilation port to the outside of the ventilation valve are sealed in a closed housing. The zero-leakage type refrigerator has the advantages of high-efficient refrigeration and heating, zero leakage and super-large power / weight ratio; and the refrigeration / heating effectiveness is 2.5 to 20.

Description

technical field [0001] The invention relates to the technical field of refrigeration. Background technique [0002] Existing gas-liquid phase-change compression refrigerators have been widely used in refrigeration devices such as refrigerators, freezers, and air conditioners, bringing many conveniences to human life, but their cooling efficiency is only 2.0 to 3.0, which wastes a lot of energy. The internal working medium has serious pollution to the human body and the atmospheric environment, which is one of the main reasons for the global warming according to statistics. It has brought irreparable loss and damage to the future living environment of human beings. [0003] The Stirling machine was invented by Stirling in 1816. The theoretical efficiency of the Stirling refrigerator is almost equal to the theoretical maximum efficiency, which is called the Carnot cycle efficiency. The Stirling refrigerator uses gas compression to heat up and release heat, decompresses and ...
