Solar driven combined cooling, heating and power system

Abstract

The invention relates to a solar driven combined cooling, heating and power system, wherein a steam outlet of a generator is connected with a working medium inlet of an expander, a working medium outlet of the expander is connected with an inlet of a water cooled condenser arranged in a hot water tank, and an outlet of the water cooled condenser is connected with an inlet of an air cooled condenser. An outlet of the air cooled condenser is divided into three paths, one path is connected with a generator by a working medium pump, the second path is connected with an indoor heat exchanger through a throttling part and the third path is connected with an outlet of a check valve. An inlet of the check valve is connected with the indoor heat exchanger after being joined with the throttling part. The other port of the indoor heat exchanger is divided into two paths, one path is connected with an air suction port of a compressor through a first switch control valve and the other path is connected with a discharge port of the compressor through a second switch control valve. A branch is arranged between a heat regenerator and the water cooled condenser. The branch is connected with the indoor heat exchanger through the second switch control valve after being joined with the discharge port of the compressor. The expander is in transmission connection with a generator.

Description

technical field [0001] The invention relates to a combined cooling, heating and power generation system driven by solar energy and capable of cooling, heating and generating electric energy. Background technique [0002] Energy saving and environmental protection are the key issues restricting the sustainable development of human beings. With the increasingly serious energy and environmental problems, the promotion and use of solar energy in ordinary people's homes is of great significance for energy saving and emission reduction, which will provide a broad space and opportunity for the development of refrigeration and air conditioning technology. Cooling, heating, and electricity are closely related to the daily life of thousands of households, and household cooling, heating, and electric multifunctional machines have broad market prospects in my country.

Problems solved by technology

[0003] In the prior art, hot water in households is obtained through gas water heaters, electric water heaters, solar water heaters or air energy water heaters. Gas water heaters and electric water heaters consume high-grade energy and have a low energy efficiency ratio. Solar water heaters or air energy water heaters have energy-saving features. meaning, but solar water heaters or air energy water heaters cannot perform cooling and heating, let alone provide electricity

Now in the family, the peers use the air conditioner for cooling. The air conditioner needs to be driven by the electric energy from the national grid, and other electricity consumption in the family is also from the national grid. It puts a lot of pressure on the national grid. In addition, in order to meet the needs of households for cooling and hot water, multiple devices need to be configured, and the initial investment is relatively high.
