Abstract: This paper proposes a new organic Rankine cycle + vapor compression cycle (ORC-VCC) system (with mechanical overheating refrigeration cycle), and this system can not only reduce the heat absorption of the ORC evaporator, ...

Abstract: In this paper, the system performance of R744 and R744/R170 mixed refrigerants used in a single-stage compression transcritical cycle at low evaporation temperature was studied by simulation method, and the effect of ...

Abstract: This paper proposes a new cascade waste heat recovery system with low power consumption and the ability to recover waste heat in a wider temperature range, namely, the absorption–compression coupled heat pump system. ...

Abstract: CO2 is a promising refrigerant substitute, and falling film evaporator is widely used in highcapacity heat pump systems. In this article, a CO2 heat pump experimental device is built. According to experimental parameters, ...
