Ultralow-temperature power generation refrigerating system and refrigerating equipment

Abstract

The embodiment of the invention relates to an ultralow-temperature power generation refrigerating system and refrigerating equipment, belonging to the field of ultralow-temperature Rankine cycle heatengine power generation. ORC organic Rankine uses a working medium with a boiling point of about 15 DEG C to realize power generation by hot water at 60 DEG C or above. According to the system, CO2, liquid nitrogen, liquid air and other extremely-low-temperature liquid with a lower boiling point are used, the boiling point of the working medium is as low 196 DEG C below zero, and power generationby hot water and hot air at 0 DEG C or above can be achieved. The core of the embodiment is to solve the problems of condensation reduction of extremely-low-temperature working media, shaft end leakage of a low-temperature working medium steam turbine or an expansion machine and the like. Therefore, a set of complete and efficient ultralow-temperature power generation system with the ultralow-temperature heat source is formed. The invention particularly relates to a technology for high-efficiency power generation through heat energy stored in high-temperature air in hot summer. The system is mainly applied to large office buildings, schools, hospitals, stadiums, shopping malls, airports, high-speed rail stations and other places and fields needing refrigerating air conditioners in the hotsummer, and is particularly suitable for high-temperature places near the equator.

Description

technical field [0001] The invention relates to refrigeration technology and related fields of refrigeration equipment, in particular to an energy-saving refrigeration system using ultra-low temperature working fluid to generate electricity, and related equipment and processes. Background technique [0002] With the development of the times, the refrigeration industry has become one of the important symbols to measure a society's economic strength, technological level and people's quality of life. Refrigeration technology plays an increasingly important role in the fields of industry, agriculture, science and technology, and national defense. [0003] Refrigeration is the process of making a space or an object reach a temperature lower than that of the surrounding medium and maintain this low temperature; the existing refrigeration system generally consists of 4 basic parts, namely compressor, condenser, throttling parts, evaporator composition. The four parts are connected...

AI Technical Summary

Problems solved by technology

The electrical energy output by power generation may not be enough for the electrical energy consumed by compressors and heat pumps; therefore, basically no one conducts research like this

Many people engaged in power generation technology and related researchers have learned and come into contact with water as the working medium for power generation. Most of them have not thought about cryogenic liquid working medium, and some people think it is impossible to achieve, and some people I think this is a "perpetual motion machine", so I won't go into in-depth research
