The device comprises a dehumidification runner, a runner type sensible heat exchanger, a condenser, an evaporator, a condensate water collecting and purifying device, a fan, a tank and an air filter. The air inlet of the tank is provided with the air filter, the air outlet of the tank is provided with the fan, the regenerated air inlet of the tank is provided with the runner type sensible heat exchanger, and the regenerated air outlet of the tank is provided with the condenser; the evaporator is arranged in front of the condenser; the condensate water collecting and purifying device is arranged under the evaporator; the dehumidification runner is arranged inside the tank. The multi-stage runner and refrigerating unit combined air-based water extracting device can heat regenerated air through solar-heated water or the refrigerating system condensate during application, and together through application of a high-evaporation-temperature refrigerating device, can greatly lower power demands. Especially in regions short in electricity, the multi-stage runner and refrigerating unit combined air-based water extracting device can be combined with photovoltaic generation to achieve zero-consumption operation.

Description

Technical field [0001] The present invention relates to the technical field of water saving, in particular to an air water intake device and method combining a multi-stage runner and a refrigeration device. Background technique [0002] In dry and severely water-deficient areas such as deserts, taking water from the air containing water vapor is an effective means to relieve water pressure. Due to the low humidity in the air in dry areas, if mechanical refrigeration is used directly, and the water vapor in the air is condensed with a cold source below the air dew point temperature, the evaporation temperature will be too low, which will cause greater power consumption . At the same time, the intensity of solar radiation in this type of area is high. Therefore, combined with the use of solar energy, the efficient condensation of water vapor in the air under high evaporation temperature can be realized, which can effectively reduce energy consumption. [0003] The dehumidification ...

AI Technical Summary

Problems solved by technology

Since the regenerated air needs to be heated before humidification, depending on the inlet status and dehumidification level of the dehumidified air, the temperature of the heat source for heating the regenerated air is in the range of 90°C to 130°C, and only electric heating or high-temperature steam can be used, which is not conducive to Low temperature heat source, such as solar energy, heat pump utilization
