Abstract
A low power dehumidifier includes a body, a desiccation element, and heat transfer elements. The desiccation element has a dehumidifying region and a recycling region. Each of the heat transfer elements has a cooling end and a heating end configured for high-temperature condensation and high-temperature heating, respectively, thereby effectively recycling waste high heat generated by the dehumidifier and reducing power consumption.
Claims17
A low power dehumidifier, comprising:
- a body internally having a first channel for taking in humid ambient air and a second channel;
- a desiccation element provided inside the body, defined with a dehumidifying region and a recycling region, and configured for communication with condensing regions and heating regions of the second channel;
- and
- at least a heat transfer element having a cooling end positioned in the condensing regions of the second channel and a heating end positioned in the heating regions of the second channel, wherein the humid ambient air is introduced into the dehumidifying region of the desiccation element via the first channel to undergo water adsorption before proceeding to the second channel to turn into recycled air, thereby allowing the recycled air to be heated up in the heating regions, undergo water desorption in the recycling region of the desiccation element, and proceed to the condensing regions where water vapor in the recycled air condenses.
