t
G
Measured gas cooler outlet temperature
t
Gsoll
Calculated setpoint for gas cooler outlet temperature depending on the outdoor temperature.
The parameter
Min. ON S1 xxm
determines the minimum switch-on time for the first stage. If the first stage is
loaded, it remains switched on for the programmed minimum operating time independent of the gas cooler
temperature.
The parameter
"Tempdif. S2 ON xx K"
defines the temperature difference at which the second stage (relay
output 8) of the spray system is switched on. If the gas cooler outlet temperature is the same or higher than the
calculated switch-on temperature S1 plus the temperature difference S2, the second stage is switched on. If the
gas cooler outlet temperature falls below the switch-on value S1 for the first stage, the second stage is switched
off again.
The parameter
Hysterese
defines a temperature range that must be undershot in order for the first stage of the
spray system to be switched off again. If the gas cooler outlet temperature falls below the switch-on value S1,
minus the specified hysteresis, the first stage is switched off again. As long as one stage of the spray system is
switched on, no fan stage will be switched back, or the fan speed will not be reduced. The following diagram is
a graphic representation of the function of the spray system:
5.17 COP
COP -
Coefficient
of Performance
- is a factor without units and is used to assess the energy efficiency of a
refrigeration pack system. The greater the COP value, the more efficient the refrigeration system. In the E*LDS
system, the COP value is calculated by the pack controller and can be monitored in the LDSWin program.
5.17.1 COP monitoring
COP –
Coefficient
of Performance
– is a factor without units and is used to assess the energy efficiency of a
refrigeration pack system. The greater the COP value, the more efficient the refrigeration system. In the E*LDS
system, the COP value is calculated by the pack controller and can be monitored in the LDSWin program. In
order to calculate the COP value, three enthalpies from the log-ph diagram are evaluated in the pack controller.
The enthalpy tables are stored in the pack controller.
