Problems solved by technology

The sound work recovery problem of the pulse tube refrigerator is solved by setting a short room-temperature expansion piston at the hot end. Therefore, when the sound work at the cold end is fully recovered, the theoretical efficiency of the new pulse-tube free-piston Stirling refrigerator is Carnot cycle efficiency

Description

technical field [0001] The invention relates to a water intake device, in particular to a solar air water intake device. Background technique [0002] The air contains a part of water vapor. Even in arid desert areas, the relative humidity in the air can reach more than 20%. Therefore, it is very considerable to use solar energy to extract fresh water from the air. Most of the air water intake devices that have been invented are adsorption water intakes, basically using adsorption materials with strong adsorption capacity, absorbing at night and heating and desorbing during the day. This kind of equipment is often bulky and inconvenient to carry and transport. Moreover, adsorption-type water intake requires a day and a night as a water intake cycle, and water cannot be extracted separately during the day. The invention patent of application number 2015105208000 "Mobile solar air water intake system" adopts traditional Stirling refrigerator for refrigeration, but the expansi...
