Example Embodiment

[0048] Example

[0049] In this embodiment, the specific process steps are as follows:

[0050] Such as figure 2 As shown, the sun 2 directly irradiates the surface of the Knudsen compressor 1 through solar rays, and the sunlight 2 directly irradiates the upper surface of the microchannel film 14 through the light-absorbing glass 10 and heats it; because it is close to the microchannel of the cold cavity 15 The lower surface of the film 14 is not irradiated by light and cannot be heated. Therefore, a temperature difference is formed from the upper and lower sides of the entire micro-passing film 14, that is, the temperature gradient that drives the Knudsen compressor 1 to work.

[0051] Such as figure 2 with 3 As shown, the low-pressure refrigerant gas enters the Knudsen compressor from the inlet 11, driven by the temperature difference, the low-pressure refrigerant gas flows from the cold cavity 15 to the hot cavity 16, and the pressure of the low-pressure refrigerant gas is incre...

Abstract

The invention discloses a refrigerating system with a Knudsen compressor as the core. The refrigerating system is composed of the Knudsen compressor (1), a high-temperature heat source (2), a condenser (3), a storage device (4), a throttling valve (5), an evaporator (6) and a dryer (7). The refrigerating system has the advantages that movement parts do not exist, lubricating oil is not needed, operation is safe and reliable, noise is avoided, pollution of the compressor to refrigerants is prevented, and the service life of the refrigerating system can be effectively prolonged; the refrigerating system is directly driven by heat energy, waste heat on some devices can be recycled, and the energy use ratio is improved; the environment-friendly novel energy, namely the solar energy, is directly used in the refrigerating system.

Description

technical field [0001] The invention belongs to the technical field of refrigeration. Specifically, it is a refrigeration system with Knudsen compressor as the core. Background technique [0002] With the continuous improvement of people's living standards, the use of air conditioners is becoming more and more extensive, the energy consumption of buildings is increasing, and the energy problem is becoming more and more prominent. At the same time, in the application of heating, air conditioning and refrigeration systems, compressors are the main energy-consuming equipment. However, problems such as power consumption and environmental pollution caused by the extensive use of mechanical compression refrigeration systems pose a huge challenge to the sustainable development of human beings. Therefore, reducing the energy consumption of the compressor has great practical significance for realizing energy saving and environmental protection of refrigeration equipment. [0003] ...
