It depend on where the aircon blow. Those area not at the aircon area will be 1-2c higher. The air blow out is 22c as set but not the room temperature.

I have a thermometer in my room for many many yrs. always monitor the temperature. After sometime, you will understand the temperature up/ down how it work.

hi all,

need some info for those hv using Pensonic Aircond..due to budget constraint, i hv too choose either Pensonic or Fujiaire aircond..any comment of this brand?i mean experience using it..
Pensonic normal 1 yr indoor warranty & 5 years compressor..
Fujiaire -1 yr indoor warranty + 2yr warranty on parts only (if register online) & 5 years compressor..

hi all,

got 1 question here. can we drill hole on beam to install aircond? will it effect the beam?

tq

The answer is no.

can but not recommend... drill hole on beam?? u mean drill wall plug to hang the in door unit or drill a big hole to run the copper piping & drain pipe??

what is the beam size??

drill a big hole to run the copper pipe. donno the size maybe standard for condo i guess.

6-8mm diameter holes to install the a/c blower unit won't hurt the beam la!

Ha ha how can be fridge to compare the Aircond?

The compressor is totally diff.

R22 gas is less presure and wanna take time to cold and once the temp is reach and cut off the compressor to be stop runing and wait the temp detect on your degree C and re-start again.

Who can tahan to hear the compressor on & off and very easy to become the compressor mounting loose with outdoor fan motor also easliy bearing getting noisy.

Fridge and A/C use similar concept. And Fridge still use temperature and Celsius for measurement.

Less pressure use in R22 does not mean longer time to cool, R22 have lower vapor pressure. And R410 or R22 does not made much difference, actually R410 performance degrade when external temperature increase.

Source - http://fire.nist.gov/bfrlpubs/build02/PDF/b02186.pdf

R22 and R410A split air-conditioning systems were tested and compared as outdoor
temperature ranged from 27.8 °C (82.0 °F) to 54.4 °F (130 °F). The R410A system tests were
extended to 68.3 °C (155.0 °F) ambient temperature with a customized compressor. When
outdoor temperature increased, the R410A system performance degraded more than the R22
system performance. While capacities of both systems were approximately equal at the 35.0 °C
(95.0 °F) rating point, at the 54.4 °C (130.0 °F) outdoor temperature the R410A capacity was
9 % below that of R22. For the same test points, the R410A COP (EER) was 4 % and 15 %
lower than the R22 COP (EER), respectively. The degradation trend was linear. Since both
systems employed identical heat exchangers and similar design (scroll) compressors, the
refrigerant and lubricant used in each system had the dominant effect on the measured results.
Operation of the R410A system was stable during all tests, including those with the
customized compressors extending up to the 68.3 °F (155.0 °F) outdoor temperature and
resulting in a supercritical condition at the condenser inlet. No noticeable changes in noise level
or operation of the system was noted.

i just bought a brand new Panasonic standard deluxe 1hp model. The outdoor unit was making strange noise and i had to call Panasonic to come and check. Turned out there was something loose in the compressor. If the sound doesn't sound right to you, just write to their customer care to call for service. But yes, i would agree that in general, the Panasonic outdoor unit is pretty noisy unlike the earlier generations. The quieter outdoor units for non-inverter airconds are carrier/toshiba and mitsubishi.

I like to switch on my fan (low speed mode) when I switch on my air cond at around 23-25 C.
It gives a good light breezy feel.
Is it gonna kill my air cond ?

I been using this method for many years. So far all the a/c still good. Only one die due to old age.

Any one knows Sharp inverter 1Hp price?Courts now got sale for them at 1K wander is its cheap. thanks

me 2, I set temp to 25, aircon fan at 2 bars, then fan is regulator KDK one at speed 1 or 2, everynite, damn syok to sleep wakakka

so phoenix, end up with sharp?? those inverter plasmacluster model?

Was confuse between new pana vs sharp anyway? any advice guys

Yup sharp, the plasmacluster got me

panasonic NKH series also comes with built-in air purifier, the nanoe-G purifier view here for my feedback of usage

Yeah bro, the sharp plasmacluster really good too, my sharp fridge and air purifier with the plasmacluster too, jeng~

Daikin wiring issue? Mind to elaborate? I just installed Daikin 1HP Inverter recently.

Added on February 19, 2012, 3:27 pmAre an inverter compressor suppose to stop spinning?

I saw my aircon compressor fan stop spinning once but then it start spinning again. I didn't stand there to monitor the compressor if it's stop again but I do realize that the compressor fan keep spinning at the same speed most of the time but I not sure whether it's spinning at full load or just partial load. The wind generated from the compressor is quite strong.

This is the temperature I set: 26c with 2 bar fan. Daikin 1HP Inverter.

Could it be the sensor wiring is not done properly?

If you ask specifically, Daikin will prefer the power supply to be near the condenser (outside unit) rather than the internal unit for their Air cond installation.
Of course usual for other brands the power supply are installed near the internal unit.
Usually air-cond installers will know what to do to work around this issue.

26c, that is way too hot for the compressor to run non stop even slow down. Try set to 23c, you see compressor running constant with variable speed.
