(5) Energy consumption calculation data (SLB-3-ER)
SLB-3-ER outputs energy consumption calculation data using USB memory. These data can be edited using commercial
spreadsheet software.
Energy consumption calculation data are created for each individual month.
<Calculation procedure>
1
The cumulative operating time is calculated for each air conditioner. (in minutes)
2
The total operating time (Ki) for each air conditioner, and the operating time in each time band (regular hours, irregular
hours) are calculated (in minutes).
Ki = Ki + K
M
K
M
= Amount of air conditioner operation in 1 minute.
The amount of operation is calculated by the following 3 methods.
The amount of operation in the case calculated for the rated opening area value for that air conditioner, E.
• MULTI 1: The conversion value considering the amount of refrigerant flowing in the indoor unit is calculated
(
∑
Ej).
(Ej: Conversion value for the opening area of the indoor unit's expansion valve.)
• MULTI 2: The time that refrigerant flows through the indoor unit is additionally calculated. (Thermostat ON time
⳯
E)
• RUN/STOP: A conversion value for the time when the remote controller is ON is added. (Operating time
⳯
E)
(E: Conversion value for the capacity of the indoor unit.)
• Use the same kind of flow volume for the same type of dynamic flow meters (gas meters).
• If MULTI-1 and MULTI-2 are set, indoor units in the blower mode cease to be objects of proportional division.
Set indoor units in the blower mode to ON or OFF if you
want to make them objects of proportional division.
• As for the standby power in the case that the air conditioner is
not used at night, etc. proportional division cannot be applied
if there are no indoor units running, so the standby power
readings will not match. Recalculate using spreadsheet
software.
• Simple software is included for editing the energy consumption calculation
data.See the included software concerning the operation method.
• Energy consumption calculation data are obtained from this unit using the USB memory.
(SLB-3-ER does not recognize commercial USB memory.)
(Example) Method of proportional distribution in case of indoor units A, B, C operating as follows (the shaded part indicates the
accumulated operating volume).
1
In case of MULTI 1 setting: Conduct proportional distribution according to the results of accumulated answer Hz.
Accumulation is not performed when the thermo is OFF or during the Fan mode operation.
Total value of operating volume
(Total value of answer Hz)
Operating volume of indoor unit A = accumulated pulse counts
⳯
power consumption per pulse
⳯
25 / 125
(25 + 40 + 60)
Operating volume of indoor unit B = accumulated pulse counts
⳯
power consumption per pulse
⳯
40 / 125
Operating volume of indoor unit C = accumulated pulse counts
⳯
power consumption per pulse
⳯
60 / 125
2
In case MULTI 2 setting: Conduct proportional distribution according to the Hz corresponding to the air conditioner capacity
(capacity equivalent Hz: fixed value) and thermo ON operating time.
Capacity equivalent Hz: equivalent value of answer Hz when exerting the indicated capacity of indoor unit (fixed value
determined according to capacity).
