The air energy heat pump component includes an evaporator, a condenser and a compressor. The condenser is connected to the solar collector plate, and the solar collector plate is connected to the four-way valve; the four-way valve is connected to a small air pump. , the small air pump is connected with the condenser; the grid sealing plate assembly includes the grid sealing plate A and the grid sealing plate B respectively connected with the four-way valve, the grid sealing plate A is filled with ammonium thiocyanate solution, and the grid is sealed Ammonium thiocyanate crystals are placed in plate B, and a heat dissipation copper pipe is connected between grid sealing plate A and grid sealing plate B. The invention uses solar energy and air energy as energy sources, and produces fresh water by cooling the air and condensing and depositing moisture contained therein, so as to realize distributed all-weather water production.

Description

Technical field [0001] The invention belongs to the technical field of fresh water preparation, and more specifically, relates to an island water production device and method based on air energy and solar energy. Background technique [0002] Due to the special geographical location of the island area, there is a problem of lack of fresh water resources. With the increase in the number of residents in the island area and the development of tourism, the problem of fresh water supply on the island has become increasingly prominent. The island area lacks small and medium-sized, low-cost fresh water. Preparation method. At present, the main island water supply method is seawater desalination, which has the advantages of short construction period and great flexibility in construction scale. [0003] In the prior art, there are mainly the following schemes for the use of seawater desalination to produce water: CN201220085939.9 discloses a small diesel seawater desalination device, which...

Problems solved by technology

[0003] In the prior art, there are mainly the following schemes for water production by seawater desalination: CN201220085939.9 discloses a small-scale diesel seawater desalination device, which uses a diesel engine as power and uses reverse osmosis to prepare fresh water. The initial basic setting of the device is The investment is large, and at the same time, due to the use of fossil fuels as power, the operating cost is high; CN200510088081.6 discloses a fresh water preparation device for sea islands and ships, which directly uses wind energy on the sea or islands, compresses air and condenses Water is used to produce fresh water, the energy is clean and the cost is low, but the device is still restricted by the instability of wind energy; CN201510120361.4 discloses a dish-type solar seawater desalination device, which uses solar light and heat resources to carry out negative pressure distillation of seawater , and then condense to obtain pure water. This device does not need to consume fossil energy, but its water production is limited by climatic conditions
