Abstract

The invention discloses an energy-saving device for extracting water from air. The device comprises a dehumidified rotating wheel (10) and a steam compression refrigerating system (20), wherein the air inlet of an evaporator (21) of the steam compression refrigerating system (20) is communicated with a regenerated air outlet of the dehumidified rotating wheel (10); the device further comprises a solar air heater (50), wherein the air outlet of the solar air heater (50) is communicated with the regenerated air outlet of the dehumidified rotating wheel (10). The device for extracting water from air provided by the invention is small in energy consumption and high in energy efficiency ratio.

Description

technical field [0001] The invention belongs to the technical field of air water intake, in particular to an energy-saving air water intake device with low energy consumption, good water intake effect and high energy efficiency ratio. Background technique [0002] In a large number of arid areas, drinking water resources are seriously insufficient, and water extraction from the air is an important way to solve the shortage of water resources. The air water intake is mainly aimed at the outdoor natural air, and converts the water vapor in the air into more liquid water as much as possible. However, since the difficulty of obtaining water from the air is closely related to the moisture content of the air, it is very difficult to produce fresh water from air with low moisture content. [0003] In order to extract water from dry air, the Chinese invention patent application "Method and device for taking water from dry air" (applicant: Chinese People's Liberation Army University...
