The pressure of the absorption chiller mainly includes evaporation pressure, absorption pressure, condensation pressure, etc. The following is a description of the relevant pressures of the absorption chiller based on the specific parameters of the lithium bromide absorption chiller mentioned in reference article 2:
Evaporation pressure
1400Pa. This is the pressure at which the refrigerant evaporates in the evaporator and is related to the evaporation temperature, with a lower evaporation pressure corresponding to a lower evaporation temperature.
Absorption pressure
1350Pa. This is the pressure at which the absorbent absorbs the refrigerant vapor in the absorber and is related to the absorption temperature. The absorption pressure is usually slightly lower than the evaporation pressure.
Condensing pressure
8250Pa. This is the pressure at which the refrigerant condenses in the condenser and is related to the condensing temperature. The condensation pressure is usually much higher than the evaporation and absorption pressures.
It should be noted that the above pressure values are for specific models and specifications of lithium bromide absorption refrigeration units, and the pressure values of different models and specifications of units may be different. In addition, the pressure of the absorption chiller is also affected by the operating environment, load changes and other factors, so it needs to be adjusted and controlled according to the specific situation in actual operation.
In summary, the pressure of the absorption chiller mainly includes evaporation pressure, absorption pressure and condensation pressure, and the magnitude of these pressure values is closely related to the refrigeration performance of the unit. In actual operation, it is necessary to reasonably set and control these pressure values according to the model, specification and operating environment of the unit to ensure the efficient and stable operation of the unit.
