QUOTE(limjenson @ Jul 15 2010, 12:54 PM) Yeah. The shop owner I go to for electronic recommends inverter for bedrooms but suggest non-inverter for living room. yes.... inverter only save when wastage occurs... when usage is minium/stable, no saving will happen.... like fridge, when I open and close frequently, the comopressor will purge up and down to compensate the temparature variance.... so, wastage occours.. inverter happens just to regulate( big/smaller) instead of open and close... example.. you have a glass that you want to fill with water.. but your tap can only either open till full or close.. you could not adjust say 10% 40% etc.. but 0% & 100%.... how you going to fill the glass with full water? imagine this... its about the same concept... |

QUOTE(PJusa @ May 19 2011, 08:55 PM) Awakened_Angel, "when usage is minium/stable,no saving will happen" is not really true. an inverter runs at higher efficiency levels (higher EER) on low load situations. i.e. if your inverter runs on low load it will outperform a regular aircon at all times. some dont hit the good EER on full load (most dont actually) and are best at at par with regular units. the key is that you need to use the inverter a/c on below full load situations. then you will permanently save for the entire duration you cool your room. so when usage is minimum is actually when savings happen. its all about how is the EER at the current load. regular A/C is different its either fully on or totally off so the EER is always stable but EER can be better with inverter A/C  Yes... I mean what I said. I used to be product engineer in hvac r n d

QUOTE(PJusa @ May 20 2011, 02:08 PM) EER is a good indicatior for the electricity required to produce the same amount of cooling i'd say. but good that we are on the same page anyway it is indeed.. but it is not whole of the story.. but part of it...which manuacturer never told the whole story... it all depends on your application in the end |
