Embodiment Construction

[0015] The invention belongs to the teaching product of popular science exhibition, which can present energy exchange and obvious heat energy change device to the audience, so that the audience can feel the energy change in the refrigerator. It can be used in science and technology museums as exhibits, and there are no similar works at home and abroad. Use models to display interesting things encountered in daily life, and convert them into experimental devices that are easy to operate.

[0016] According to the microscopic interpretation of thermodynamics and the first law of thermodynamics in physics, as well as the principle of adiabatic process. First, the gas is compressed into the gas storage tank. When the gas in the gas storage tank is released, the gas quickly flows through the gas outlet pipe 3 on the other side, the contact area with the outside world increases, the gas pressure decreases, and the gas has a "thrust" to the outside world. , this "thrust" can be unde...

Abstract

The invention discloses a refrigeration principle type display device. The refrigeration principle type display device is characterized in that the display device has a structure that an air outlet of an air tank is connected with a T-branch pipe through an air duct, the T-branch pipe is respectively connected with an air inlet pipe and an air outlet pipe, an air inlet valve and an air outlet valve are respectively arranged in the air inlet pipe and the air outlet pipe, and a valve core is arranged on the air inlet pipe. Because the structure is adopted, the display device has the advantages that 1, a refrigeration principle and even an energy conversion process can be simply and clearly shown; 2, the display device is simple and easy to move and is suitable for various scientific knowledge spreading occasions; and 3, the display device is simple in structure and is low in manufacturing cost.

Description

technical field [0001] The invention relates to a science and education model, in particular to a display device for refrigeration principles. Background technique [0002] With the development of society, air conditioners have entered thousands of households and become an indispensable electrical appliance in our daily life. [0003] But how the air conditioner is cooled, and its working principle is unknown to many people. For this kind of knowledge, even the conversion of energy, there is still no special scientific and educational model to display it, which is not conducive to the development of teaching. [0004] It is a problem to be solved in the prior art to provide a display device so that it can simply and clearly display the refrigeration principle and even the energy conversion process. Contents of the invention [0005] The technical problem to be solved by the present invention is to provide a display device for the refrigeration principle, so as to achieve...
