Webrefrigerant enters the condenser at 16 bar (abs) and 160 °C, and saturated liquid exits at 16 bar (abs). There is no significant heat transfer between the compressor and its surroundings, and the refrigerant passes through the evaporator with a negligible change in pressure. If the refrigerating capacity is 150 kW, determine: WebThe superheat level indicates the level of the refrigerant present in the evaporator. If the superheat is higher than the average level, the refrigerant is less than the required level in the evaporator. The following are the reason for the lower refrigerant in the system,. The technician has charged low refrigerant than an actual level requirement; the device resists …
