Abstract：CO2 has many advantages,such as environmental friendliness,good stability,and low production cost,and it is considered to be an ideal refrigerant for the next generation.However,the transcritical CO2 refrigeration cycle has a low efficiency due to high pressure issues,and the condensation dehumidification efficiency is poor.To solve these problems,this paper proposes a transcritical CO2 compression refrigeration system coupled with a solution dehumidification system and conducts theoretical simula-tion and analysis.It is found that under different operating conditions,the efficiency of this system can be improved by 10%～80%compared to a standalone CO2 refrigeration cycle system,indicating its broad development potential and application prospects.
