FIELD: physical processes. SUBSTANCE: invention relates to a non-volatile continuous operation solar distillation system characterised by containing in the upper part of the body of the solar distillation unit with a translucent coating and filled with salt water an evaporator of a diffusion-absorption refrigeration system consisting of a cooling agent vapour generator connected with the condenser thereof placed in the water of the distillation unit and of a cooling agent vapour heater connected via an accumulator battery charge controller to photovoltaic modules, wherein a condensate collector with a fresh water container is connected to the evaporator in the lower part thereof, the translucent coating of the distillation unit and the photovoltaic modules are oriented in the direction of the sun, and a heat accumulator with a phase transition of a substance, e.g., paraffin, is connected to the container of the solar distillation unit, as well as to a non-volatile continuous operation solar distillation system characterised by containing in the upper part of the body of the solar distillation unit with a translucent coating and filled with salt water an evaporator of a diffusion-absorption refrigeration system consisting of a cooling agent vapour generator connected with the condenser thereof placed in the water of the distillation unit and a cooling agent vapour heater connected to a high-temperature heat energy accumulator tank connected with the heat exchanger of a solar energy concentrator, wherein the heat exchanger is installed in the optical focus of the concentrator and the latter is oriented in the direction of the sun. EFFECT: creation non-volatile solar distillation system with continuous operation. 2 cl, 4 dwg.
