Water vapour is changed into hot water, and the process that water vapour becomes hot water is an exothermic process, can also make temperature rise, then these heat
The water vapour that water and temperature and pressure increase flows into condenser pipe 3 and releases heat again, and remaining water vapour is all turned
Become water, the heat released during this is recycled utilization for the water in heating evaporation device 2, i.e. thermal energy；It is flowed in condenser pipe 3
The hot water gone out is condensed water, also referred to as distilled water, then distilled water inflow heat exchanger 7, and evaporation is flowed into for heating by heat exchange
The raw water of device 2 further recycles thermal energy, and the temperature of the distilled water then flowed out from heat exchanger 7 is close to raw water temperature, i.e., hot
It can substantially all recycling.So the heat utilization rate of the solar distilling water purifier of the present embodiment is very high, even if too
When positive irradiation intensity is weaker, also there is good effect, the reason is that：The solar distilling water purifier of the present embodiment adds solar energy
Pyrogen is managed and heat pump principle has carried out organic combination, under the action of compressor 4, it might even be possible to by reducing by 2 shell of evaporator
The temperature of body absorbs the energy in air, and to be referred to as heat pump type air can distill water purifier.
