Refrigerator model compilation method
The unit is divided into single-effect and double-effect types.
The single-effect unit uses 0.1MPa (gauge pressure, the same below) saturated water vapor as a heat source to produce 7C cold water. 3.1.1
The double-effect unit uses the following four different pressures of saturated water vapor as a heat source to produce cold water of different temperatures. That is: for a 0.8MPa unit, the cold water outlet temperature is 7°C; for a 0.6MPa unit, the cold water outlet temperature is 7 or 10°C; for a 0.4MPa unit, the cold water outlet temperature is 7 or 10°C; for a 0.25MPa unit, the cold water outlet temperature is 13°C. d.
