Scroll vapor injection
Webb1 okt. 2024 · Winandy and Lebrun (2002) presented a semi-empirical model of a scroll compressor with vapor-injection and liquid refrigerant injection working with R-22 as refrigerant. The mass flow rate, compressor power, and discharge temperature of the compressor were predicted within ±4%, ±4.5%, ±5 K, respectively. WebbWith EVI (Enhanced Vapor Injection) several positive parameters can be achieved which are especially useful for heat pumps. By injecting the refrigerant directly into the SCROLL compressor head, the conditions in the refrigerant circuit of the system change.
