Are those freestanding A/C units worth the money?

41 posts in this topic

I saw them at Big C, I think they were on roller wheels. They seemed to blow cold although they had the benefit of pre conditioned air in the store already. I don't have the option of buying a window A/C so was wondering if these were decent for their price? Being in Pattaya I don't need to drop the temps that much most of the year.

The majority are efficient, (I have one) however, please check the "noise" output. Some can be unbearably noisy. I do not know which one emits the least noise, but hopefully, someone else may have done the research and can advise you - good luck

PS Mine is refrigerated NOT evaporative.

i bought a HATARI AIR COOLER [ht-ac1or1] classic 2,900bht. comes with 2ice packs.

my beloved dog suffers with the heat so this was ideal,not as good as air con in the bedroom but down stairs its fine for him.

they have a water tank 8ltrs.so i put 4 x 1.5ltrs.of water in the fridge overnight and it lasts around 8hrs.once you switch on.

when the water gets to minimum it switches off auto.ours has  4cool speeds,so far 2 is fine.

putting cold water plus one ice pack works fine.

when in the store have a look at what setting its on[1234] and if an ice pack is in the sump.gives you an idea how cold they are.

there is the next size up AIR COOLER TURBO around 5k.bht.

The Mrs. tells me they can be heavy on electricity?

Firstly I do not own one or would ever consider buying one. My experience is in building management.

These units can provide limited cooling but they are very inefficient. As mentioned they are noisy, that noise is wasted energy. The energy used to chill the water and freeze the ice packs also needs to be taken into account. High humidity also lessens there cooling effect. The reason they can look good in the stores is the air is already well conditioned, it is low temperature and low humidity air. These units expel cooler wetter air and that gives the appearance of being colder than it is.

All considered I would never recommend these units to be used at home.

the evaporative type air "cooler"s are marginal in Thailand, if humidity is low (not a usual condition) when you will be some cooling effect. In saying that I have one and feel it is a little better than the bedroom ceiling fan during the night time but tends to be noisier than the slow running ceiling fan - so it's a compromise .

These are what we call a swamp cooler the humidity needs to be low for them to work efficiently, here in the north a good option during the dry season. As it is stated on the cooler they will only drop the temp. 5 to 15 degrees again that depends on the humidity.

Place them near a outside air source a window or door so they can pull the hot dry air from outside also open any other windows and doors a bit to allow the air to be forced thru the room and outside, if you are only getting the air inside thru the cooler then eventually they will stop working because of the humidity rising in the room. Remember they will only cool down 5 to 15 degrees.

We have the standard water cooler and it needed minor repairs. Took it to the local guy and my partner said he was considering buying one of the stand alone air cons for his mother. The response from the Thai repair guy was to save his money, they have a limited shelf life, break down a lot and then are useless. Words from a guy who you would think would be quite happy to take your money.

We had one temporarily in a very small room and it worked very well, however it was noisy and used a lot of power. We gave it away so it is now in a studio/ study.

Normally they come with a "window kit" which exhausts the heat from the condenser outside, so you will preferably need a sliding window that can be locked slightly open.

I use in 1 room only, the bedroom. Don't expect to chill your whole house down. If you run it for 6-7 hours for sleeping, the electric bill will still be OK.

I had one and found it to be a total waste of money. It was useless.

Seems to me we are discussing two entirely different machines on this thread. The OP, if I'm not mistaken, was enquiring about free-standing A/C units, not the evaporative units which use water cooled by ice-packs. One adds considerable humidity with minimal benefit and the other, if used with the aforementioned window kit to vent the heat generated by the condenser, would probably work fine as the unit should not be overworked due to being forced to overcome not only ambient temperatures but the heat generated by the unit, as well. However, the room size and location (lower, as opposed to upper level) would be key variables when gauging power consumption and wear and tear would be the chief concern if the unit were not to be adequately vented. Otherwise, power consumption should be comparable to a wall/ceiling mounted unit with an external condenser, with the only plausible benefit other than price being mobility. Doubtful you will find decent free-standing A/C units for less than 15K baht, however. And Big C is not exactly known for big ticket items. I would give Homepro or one of the independent dealers a look. Also, if you have stairs, that would detract from its "ease of maneuverability." These things aren't generally light.
