Abstract
A cogeneration system to generate thermal energy in form of hot water, using the system's solar collector directly as an evaporator and a heat exchanger integrated in a thermal tank used as a condenser. A variable capacity expander (turbine) is used and the organic working fluid selection is specific for this application. Thus is provided a technological alternative for the production of electricity and thermal energy using a renewable energy source.
Claims6
A cogeneration system for integration into solar water heating systems comprising:
- a solar collector;
- a condenser having an input connected to the solar collector, the condenser including a heat exchanger inside a hot water storage tank;
- an expansion device located between the solar collector and the condenser;
- a first two-position, three-way valve having a first side connected to the solar collector, a second side connected to the condenser, and a third side connected to the expansion device;
- a pump connected to an output of the condenser;
- an auxiliary heat exchanger located between the condenser and the pump;
- a receptor tank located between the heat exchanger and the pump;
- a second two-position, three-way valve having a first side connected to the output of the condenser, a second side connected to an input of the pump, and a third side connected to an input of the auxiliary heat exchanger;
- wherein in a first position, the first two-position, three-way valve passes a working fluid from the solar collector towards the condenser, and in a second position the first two-position, three-way valve conducts the working fluid from the solar collector towards the expansion device,
- wherein in a first position, the second two-position, three-way valve passes the working fluid coming out of the output of the condenser towards the pump, and in a second position, the second two-position, three-way valve passes the working fluid coming out of the output of the condenser towards the auxiliary heat exchanger;
- wherein an output of the auxiliary heat interchanger is connected to the input of the pump and the output of the pump is connected to the solar collector.
