(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>
1The cumulative operating time is calculated for each air conditioner. (in minutes)
2The 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 time⳯E)
• RUN/STOP: A conversion value for the time when the remote controller is ON is added. (Operating time⳯E)
(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).
1In 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 counts⳯power consumption per pulse⳯25 / 125
(25 + 40 + 60)
Operating volume of indoor unit B = accumulated pulse counts⳯power consumption per pulse⳯40 / 125
Operating volume of indoor unit C = accumulated pulse counts⳯power consumption per pulse⳯60 / 125
2In 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).

Total value of operating volume
(capacity equivalent Hz⳯remote controller ON time)
Operating volume of indoor unit A = accumulated pulse counts⳯power consumption per pulse⳯40 / 160
(40 + 50 + 70)
Operating volume of indoor unit B = accumulated pulse counts⳯power consumption per pulse⳯50 / 160
Operating volume of indoor unit C = accumulated pulse counts⳯power consumption per pulse⳯70 / 160
Total value of operating volume
(capacity equivalent Hz⳯thermo ON time)
Operating volume of indoor unit A = accumulated pulse counts⳯power consumption per pulse⳯30 /150
(30 + 50 + 70)
Operating volume of indoor unit B = accumulated pulse counts⳯power consumption per pulse⳯50 / 150
Operating volume of indoor unit C = accumulated pulse counts⳯power consumption per pulse⳯70 / 150
3In case of RUN/STOP setting: Conduct proportional distribution according to the Hz corresponding to the air conditioner
capacity (capacity equivalent Hz: fixed value) and remote controller ON time.
Same as 2, the capacity equivalent Hz (fixed value) is accumulated according to the remote controller ON time only.
Accumulation is also performed when the thermo is OFF and during the air supply operation.
Indoor unit A Indoor unit B Indoor unit C
30Hz 50Hz 70Hz
Indoor unit A Indoor unit B Indoor unit C
40Hz 60Hz 70Hz
Different from 1, the fixed value is accumulated irrespective of the answer Hz. Accumulation is not performed when the
thermo is OFF and during the Fan mode operation.

For owners the fee apportionment for multi machine air conditioners is more complicated and harder to explain to
customers. In many cases it's best to use simple explanations.
In addition, consumption for multi machines are calculated based on volume, making it easy for excessive cooling
and differences in building load to lead to discrepancies in electricity consumption.
These different values are hard to explain. Therefore, it is easier to explain how many horsepower were used for
how long.
At this point, recommend [RUN/STOP] registration.
Both multi machines and single machines use [RUN/STOP] registration.
Recommend that separate electricity meters be installed for single machine and multi machine systems.
Display every unit of electricity (kW) on the electricity consumption board. For example, register P280H as 28.0.
Current operational value = electricity volume⳯time of operation, calculated according to the electricity volume ratio.

When No. 4 shielding wire is used, always ground the single wire side of the shielding wire. In addition,
using the shielding wire is helpful to prevent the incorrect connection between 5V DC and 220/240V AC
because the discrimination from the power supply wire is clear.

1Find the total capacity of all connected air conditioners
2Assume that the correct electricity meter is being used
3Air conditioners operating at full load: assume summer overload power consumption⳯1.2
For example, Set the total electricity consumption = 100kW, power rate = 90%
Operating at full load = 100⳯1.2 = 120kW
With 3 in conjunction, 1 = 120⳯1000/ (1.732⳯200⳯0.9) = 385A
→ Electricity meter must be 400A
If you use 400A Mitsubishi transmission equipment, then
• K11 type, pulse unit at 100kWh/P
select while at 10kWh/P
• K11 type, pulse unit at 100kWh/P
10kWh/P
select while at 1kWh/P
• There are other products with smaller pulses, ask an electric meter manufacturer for details.
4Inspection while electricity consumption is at 120kWh
●When pulse input is highest
Use 0.1kWh/P, then 1200P/h = 20P/min exactly 1 minute 20 pulse (300pulses or fewer)
10 minutes 200 pulses OK
Use 1kWh/P, then 120P/h = 2P/min exactly 1 minute 2 pulses
10 minutes 20 pulses OK
Use 10kWh/P, then 12P/h = 0.2P/min , so 1 minute no pulses
10 minutes 2 pulses OK
●Lower usage rate, for example 1/10 time (12kWh),
Use 0.1kWh/P, then 120P/h = 2P/min so 1 minute 2 pulses
10 minutes 20 pulses OK
Use 1k h/P, then 12P/h = 0.2P/min , so no pulses in 1 minute
10 minutes 2 pulses OK
Use 10k h/P, then 12P/h = 0.2P/min , so 1 minute no pulses
10 minutes no pulse NG
5Pulse units should reach 0.1kWh/P.
• 10kWh/P is NG.
• 1kWh/P usage rate is the lowest, there might not be any pulses in 10 minutes, causing a calculation error.

Note (1) Electricity meter pulse unit, please select 10kWh/P or less.
(Example) using 3 phase 200V– 30A electric meters, power rate at 100%, largest flow will be 30A
Electricity consumption = 3⳯200⳯30⳯1.0 = 10, 392 kWh
This time, set to 0.1kWh/P, so 103, 920P/h = 1730 pluse/minute NG
Set to 1.0kWh/P , so 10, 392P/h = 173 pluse/minute OK
Set to 10.0kWh/P, so 1, 039P/h = 17.3 pluse/minute OK
