Question
No.
Answer
Why is an electricity charge generated even though none of the indoor units is being used?
Since power is consumed by the outdoor unit even when all the indoor units are not in use, an electricity
19.
charge is generated.
To prevent generation of an electricity charge, turn off the power of that indoor unit and perform scan to
remove the indoor unit from the electricity charge apportionment function objectives.
Why isn't the operation time and electricity charge proportional?
If the room temperature has reached the set temperature even if the operation is turned ON by a remote
controller, the indoor unit will not operate and the power consumption will be that much lower.
20.
In addition, if the difference between the room temperature and the set temperature is large, more power
is consumed than when the difference is small. Therefore, the operation time and electricity charge may
not necessarily be proportional.
Why is the electricity charge of operated indoor units so much smaller than that of indoor units that are not
operated at all?
Electricity charge includes the power consumed by the outdoor unit in addition to that of the indoor unit.
The outdoor unit consumes power constantly so that operation at any time is possible even though indoor
units are not operating. This is called the "standby power". Since the standby power differs between the
21.
models of outdoor units, if the number of indoor units per outdoor unit is assumed to be the same, the
indoor units which use an outdoor unit will consume more power than indoor units which use with high
standby power.
This question is an example of when the difference of this standby power was larger than the power con-
sumed by operation. This is a normal result. Generally, this kind of difference is made small by selecting
the model of outdoor unit based on appropriate facility design.
Why has the electricity charge suddenly increased even though the use is the same as in the past?
One of the reason could be that some tenants have moved out. The electricity charge is apportioned
between blocks. When the number of blocks decreases or increases by moving in and out of tenants, the
22.
electricity charge increases and decreases. As an example, if the basic charge is set so that it is equally
apportioned between the blocks, then the electricity charges decreases if tenants move in and increases if
tenants move out. The building owners and managers should perform appropriate settings in accordance
with his/her policy as to how things should be in such cases.
