Description

The invention relates to the construction of aircraft, in particular to the construction of solar water lifters, and can be used in the design of general medical systems for raising water from water sources. A solar water lifter is known that contains a working chamber, equipped with suction and discharge pipes with non-return valves and connected to a cooling device made in the form of a tank, communicated with the working chamber 1. The disadvantages of a solar water lifter are the low utilization rate of heat incident on the steam generator-heat receiver and, consequently, the low efficiency of the water lifter. The most similar to the invention according to its technical nature is a solar water lifter containing a working chamber equipped with suction and discharge pipes with non-return valves and also cooled with a float valve, a condenser, with a cooling jacket and a siphon drain, a steam generator-heat exchanger and a capacitor communicating with it and The working chamber pressure tank, located below the last 2 3. The disadvantages of the known solar water lifter are low efficiency due to the use of a significant part of the raised water for convective cooling of the condenser, as well as increased metal consumption due to the presence of the tank and cooling jacket. The purpose of the invention is to increase the efficiency of a solar water lifter by reducing the flow rate of cooling water. The goal is achieved by the fact that in a solar water lifter there is a working chamber equipped with suction and discharge pipelines with non-return valves, as well as a cooling nozzle with a float valve, a condenser with cooling a jacket and a siphon drain, a steam generator-heat exchanger and a pressure tank connected to it by a condenser and a working chamber, located below the latter, a cooling pipe at the outlet with abzhen sprinkler located above the condenser and the cooling jacket is formed as a porous coating. 28 The figure schematically shows a solar water source, a longitudinal section. The solar water lift contains a working chamber 1, equipped with suction and discharge pipes 2 and 3 with check valves 4 and 5, as well as with a cooling pipe 6 with a float valve 7, a condenser 8 with a cooling jacket 9 and a siphon drain 10, a steam generator-heat exchanger 11 and communicated with With it, the condenser 8 and the working chamber 1 have a pressure tank 12 located below the latter, cooling the 1st branch pipe 6 at the outlet is equipped with a sprinkler 13 located above the condenser, and the cooling jacket 9 is made in the form of a porous coating and pressure AK-12 is provided with conduits 14 and 15. The solar water lift operates as follows. In the initial position, the steam generator-heat exchanger 11, the pressure tank 12, the pipe 14 connecting them and the pipe 15 connecting the pressure tank 12 with the working chamber 1 are filled with a working agent, for example, freon-113, which has a boiling point at working pressures 5070 With and practically insoluble in water. The working chamber 1 and the suction pipe 2 are filled with water. When the sun is heated: -: And in the steam generator-heat exchanger 11, the working agent begins to evaporate, which leads to an increase in pressure, which starts displacing water from working chamber 1 through the check valve 5 into the pressure pipeline 3 and then to the consumer. At the end of the evaporation process of the working agent in the steam generator-heat exchanger 11, the level of the working agent in the working chamber 1 rises to the float valve 7 and it opens. Due to the process of expanding the vapor of the working agent, water begins to flow through the cooling nipple b and the sprinkler 13 to the cooling jacket 9 of the condenser 8, which leads to the moistening of the cooling jacket 9. Evaporated on its surface, water begins to draw heat from the walls of the condenser 8, which causes intensive condensation of vapors of the working agent in the working area of the condenser 8, and therefore, a sharp
