My aircond installer recommend me Daikin inverter 2hp for my living hall. Fr what I gather here, no need to use inverter type for large hall area. Reason being that since compressor will not be start-stopping, so inverter tech will not be fully utilize for cost savings. Is this true?
Btw, anyone here knows the price for inverter and non-inverter type? Tq.
This is very common air salesman would tells u this.
Inb4 yes, nowadays don't have it issue.. Even inverter can perform much better and energy saving.
Inverter vs non-inverter
Inverter have part load.. From starting boot up from minimum power, after certain take mid or full load.
Non-inverter don't have minimum and most of time would full load until on & off times.
For inverter no matter how big of your living hall these only fully utilize on that particular place.
Once temperature reaching and reduce the energy on part load until you change new setting.
Actually these is very common sense.
Non-inverter design for once temp. Setting degree are reaching will sending signal to compressor stop work, until the weather change warm then start with full load maximum power on 2.2kw for while and keep remain on 1.6-1.8kw only.
Inverter will start from minimum power when starting running compressor on 0.4kw - mid 0.6kw - until maximum run on 1.9-2.2kw once temp. Reaching and reduce to part load of 0.6kw only.
Even bigger hp you only pay for 1hp non-inverter bill only.
