Abstract
Provided is a self-adaptive multi-mode device for high-efficiency and all-weather water harvesting from air. Electromagnetic three-way valves and a four-way reversing valve are controlled by a PLC module integrated with energy efficiency algorithms, thus realizing a device for water harvesting from air capable of self-adaptively switching working modes according to the working environment. By controlling the four-way reversing valve, heat energy and cold energy released by the condenser and the evaporator during the heat pump cycle can be fully utilized, and sorbent coatings at the cooling side are always kept in a sorption state, and sorbent coatings at the heat release side are always kept in a desorption state, so that continuous and high-efficiency water supply is realized, presenting higher energy conversion and utilization efficiency than the conventional electrical heating or electrical refrigeration technology.
