Problems solved by technology

However, there are certain deficiencies in this technology: first, in the refrigeration process, the working fluid does not undergo a phase change, and refrigeration is mainly achieved by the change of sensible heat of the working fluid, so the cooling capacity is limited to a certain extent; The carrier makes the system equipment structure and operation more complicated

Abstract

The invention provides a solar energy-natural gas complementary injection type distributed combined cold heat and power supply device, comprising a turbine expansion engine, a generator, an ejector, a condenser, a working medium storage tank, a working medium pump, a refrigerating evaporator, a throttle valve, a heat source exchanger, a first valve, a solar thermal collector, a conduction oil storage tank, an oil pump, an afterburner, a second valve, a third valve, a fourth valve, a first bypass valve and a second bypass valve. Electric powder required by the whole circulating process can be supplied by the system self, and extra electric energy and cold can be outputted to meet the load requirement of a user of a cold and power supply distributed energy supply system.

Description

technical field [0001] The invention relates to a device in the field of energy technology, in particular to a solar energy natural gas complementary injection type distributed electric cooling and heating cogeneration device. Background technique [0002] Solar energy is rich in resources and can be used for free without transportation, without any pollution to the environment. It is a renewable energy source, inexhaustible, clean and safe. In practical applications, solar energy adopts photovoltaic power generation and photothermal utilization, and the cost of solar photovoltaic power generation is high. Solar thermal energy is used as a heat source to heat heat transfer oil. Due to the large heat capacity, strong thermal conductivity, and high boiling point of heat transfer oil, compared with conventional water, the work Low pressure, better practical usability, suitable as heat source working medium, and low boiling point of organic working medium is suitable for power g...
