Description

i1 Invention from the Russian Federation to cooling and cooling equipment, and more specifically to solar power plants for the production of cold and hot water. The aim of the invention is to maintain a constant water temperature directed to the consumer. The drawing shows schematically the proposed installation. It contains a refrigeration circuit 1 in which a steam generator 2, an ejector 3, a condenser 4, a pump 5v choke 6 and an evaporator 7, as well as a circuit 8 for water circulation with its pump 9, con; Sensor 4, solar heater 10, steam generator 2 and a consumer of hot water (not pocketed) injection f 11 with valve 12 at the entrance to er6 receiving chamber, thermal sensor 13 connected via valve 14 to valve 12 .: The installation works in the following way. Water is pumped by pump 9 into a condenser 4 in which it is heated by heat, at the time of condensation of the refrigerant vapor mixture. Next, the water is directed to the injector 11, 2 in which a predetermined part of the water is directed to the consumer. After the injector 11, water enters the solar heater 10, in which it is heated to a high temperature. Thereafter, the highly heated water is used in the steam generator 2 to evaporate the refrigerant vapor at high pressure. Partially cooled but still hot water is directed to the consumer, the temperature of which is maintained constant due to the action of the thermal sensor 13 connected through the actuator 14 to the valve 12. At this time, a part of the liquid x of the adagent from the condenser 4 is fed through the choke 6 to the evaporator 7 , which boils at low pressure, producing a cooling effect. The remaining part of the liquid refrigerant is sucked in by pump 5 and injected into steam generator 2, in which, as indicated above, evaporates at high pressure and is used to eject vapor of very low pressure from evaporator 7. This vapor mixture is liquefied with water in condenser 4. circulating refrigerant through circuit I.
