An ammonia refrigeration cycle, an evaporator that cools and liquefies CO2 using the latent heat of vaporization of ammonia, and a liquid pump on a feed line that feeds liquefied CO2 cooled by the evaporator to the cooling load side In the CO2 brine generating device, the liquid pump is a...
CO2 is not new to refrigeration. Its use began in the mid-nineteenth century and steadily increased, reaching a peak in the 1920s. Its use declined with the introduction of chlorofluorocarbons (CFCs) that operated at much lower pressures. Use of CO2 continued, but chiefly in cascade systems f...
A refrigeration system for condensation of carbon dioxide (CO2) in a flue gas stream (55), said system comprising a refrigeration circuit (50), a flue gas treatment system comprising a flue gas compressor (44) and a refrigeration system for condensation of CO2 (66,72), and a method for ...
A correlation of optimal heat rejection pressures in transcritical carbon dioxide cycles [J]. Appl Therm Engi, 2000, 20: 831-841. [12] KIM Mo Se, KANG Dae Hoon, KIM Min Soo, et al. Investigation on the optimal control of gas cooler pressure for a CO2 refrigeration system with an ...
The control problem of heat rejection pressure for a CO2 refrigeration system can be explained by referring to Fig. 1. Assume that the heat rejection side surrounding temperature is T1 and the refrigerant temperature at gas-cooler outlet is also T1. Then, one can consider and compare the perfor...
The system schematic of the CO2transcritical refrigeration22experimental rig is shown in Fig.1. In this system, an auxiliary cooler was added to improve the COP of the system and reduce exergy destruction of the system. A 0.2 kW heating device was added to the inside of the refrigeration cont...

CO2refrigeration unitCOP improvementA global efficiency of the ejector with a swirl generator only increases at moderate motive nozzle pressures.A positive swirl generator effect is independent of the fixed ejector size.A swirl generator should only be located at the inlet of the motive nozzle for ...
The heat exchangers were mounted in a specially designed test facility that allowed the control of different test conditions and parameters, including air on temperatures and flow rates, approach temperatures and CO2operation pressures. The integrated refrigeration system can provide specified CO2fluid ...
摘要:由于化石能源的消耗以及环境的恶化,各国都开始寻找新型发电技术。SCO2布雷顿循环身为新兴的技术,具有临界参数易达到、体积小、重量轻、循环效率高等优点。将布雷顿循环工质进行比较,得到SCO2是最适合布雷顿循环的。之后将SCO2布雷顿循环与朗肯循环进行比较,得到SCO2布雷顿循环与光热发电相结合的效率更高。基于光热发电...
