Blyss 1.1kW Portable Air Conditioner Inadequate Cooling Performance - Warranty Query

sirkubax 51045 29
Best answers

Why is my portable air conditioner only cooling the room by 1–2°C, and can it be fixed under warranty?

The most likely cause is low refrigerant from a leak, so it should be claimed under warranty rather than treated as normal behavior [#10947995] One reply also suggested checking the evaporator and condenser temperatures to confirm the fault, and the symptoms described later still matched a unit that was barely cooling despite the compressor and pipes getting hot/cold [#10948713][#10951020] Another reply noted that a clogged capillary could cause similar behavior, but still pointed to warranty replacement if the unit is from a store/market sale [#10951344] In the end, the air conditioner was replaced with a new one under warranty, and the replacement cooled properly [#11014139]

    Hi,

    This is my second post on this topic :)

    I have a Blyss 1.1kW portable air conditioner, bought a year ago (so still under warranty).
    Recently, it cools very poorly, although I would like to point out that it's hard to say "how weak" because the air temperature has increased significantly.
    The air in the room is about 28-29 degrees (machines are working). As it was cooler outside, the air conditioning easily maintained the set temperature of 21 degrees.
    Quite warm air is pushed out from the pipe outside, but the air inside is only 1-2 degrees cooler than the temperature in the room (i.e. when the room is 28 degrees, the air in the climate is 26-27 degrees).
    I turned on the airflow to the max, but I'm just wondering if the cooler air would not be with less blower power ...

    Is it normal? Is the air conditioning not working, or maybe the gas has flown, or something has broken down ...

    I dismantled the housing, and cold gas is flowing to the radiator cooling the room air (frost has settled on the intake pipe).
    The radiator cooling the working medium (the air from it is expelled outside the room) is warm, and the condenser? (the larger refrigerant tank) is very hot - it burns to the touch.

    Do I have to accept it or is there a chance the warranty will fix something??
    1-2 degrees lowering the temperature is probably not enough...

    Your air conditioner is low on refrigerant, there is a leak somewhere.
    If it's under warranty, advertise it.

    Hi,

    Thanks a lot for the hints :D the electrode is brilliant.

    Tonight after the night the temperature dropped to 24 degrees, but the night was cool.

    Yes - that larger tank is the compressor.

    Well, then I'm looking for a guarantee :)
    Unless there's something else I can check myself?

    Is it normal that the air conditioner needs to be refilled after a year? Just wondering if it will be covered under warranty...

    EDIT
    I am attaching a photo of what it looks like now.

    Hmm

    Both are summer.
    The condenser is slightly warmer than the air and the evaporator slightly cooler.
    Although the air expelled outside is warm (not hot).

    I have the impression that the air conditioning cools, but only 1-2 degrees, which is something broken - probably the lack of the factor.
    She's packing it in the car tomorrow and under warranty...
    I'll let you know when he comes back so posterity will know how to do it :-)

    There may also be capillaries clogged and the effect will be similar, and as for the warranty, if it is from some market, they should replace you with an efficient air conditioner.

    Hello, I have a question, I bought a ladycook lpc-sp09 portable air conditioner, but I have a question because it is not clear in the instructions on the back of the device, there are two holes, one somewhere 30cm from the ground with the inscription "connection of the ventilation duct" and the other at the very bottom with a rubber stopper. And now it kind of has a container for condensed water but I don't understand how to remove it. Do you put the attached hose where the inscription or put something under the device and remove the plug? And what does it mean continuous or non-drainage of water? and is it normal that after 3 hours of work it has about 1 liter of accumulated water?

    It depends on many factors (humidity, air flow, temperature difference, etc.), but it is possible (larger devices can give a bucket of 15 liters per hour :D )

    I understand, thank you for the explanation. But how to remove this water? Why this hole with the inscription ventilation duct when it is placed about 30 cm from the ground? Now I manage to put the bowl under the bowl and wait for it to fly out. What does water drainage mean?

    fan duct it's probably a warm air discharge (i.e. a pipe and out of the window - that's what most people do).

    In the back you have a flap and a condensate tank under it and you should empty it, and if you have the opportunity to drain it, for example, to the sewage system, then you pull out the rubber plug, connect the pipe and to the sewage system.

    Hello.

    Eventually they replaced the air conditioner with a new one under warranty.
    They didn't say what went wrong so I have no feedback
    The new one cools great :)

    Hello, I have another problem for a few days the room is 26 degrees, I turned on the air conditioner and at the beginning it hums terribly as if the coil was getting stuck in 10 seconds it stops but it worked all day and it did not cool down the room by maybe one degree. Is something wrong? Please help because the air conditioning is new, maybe 3 weeks old and works well until the heat.

    Added after 5 [hours] 31 [minutes]:

    Hello again, is it normal that the air comes out of the air conditioner instead of 13 degrees, as at the beginning it is now 22 degrees, I have 25 degrees in the room and it does not go lower. As it was 22 degrees in the room, the air conditioning was 14 max 13 degrees. The device is new, maybe 3 weeks old. Please help.

    Hi,

    Your symptoms are similar to mine.
    There is a difference of 2 degrees between input and output.
    Check out of curiosity whether you have warm or hot air at the discharge. They replaced the entire air conditioner, and when it was broken, the air was warm. Now it's really hot (45? degrees - I'll try to measure for you)

    I don't know what was wrong with me - he replaced it with a new one and they didn't say, but probably some gas leak.
    If you're under warranty, don't wait - you need to advertise.


    edit:

    I took a measurement by reference.
    With the air temperature in the room 23 degrees, the air conditioning set to min (16 degrees)
    Cooler air: 11 degrees
    Warm to the core ~48 degrees

    Hello yes already reported may arrive tomorrow. Cool air flows from the pipe, but after removing the panel, the compressor is terribly hot, you can't touch it with your hand. At the beginning it worked well, it had 13° on throw and now 23°, sometimes 20° when the room is 24°. He worked half the day in the room and did not cool anything. So the gas must have escaped somehow.

    My compressor was also very hot, and no effect at all.
    You can see the photos above - the intake pipe to the radiator was frosted, but there was no effect.

    I think you have exactly the same problem as me. I gave it back under warranty, and after about 8 days I called, and they already had a decision to exchange it for a new one - I recommend calling earlier than 14 days.

    If they tell you what went wrong, let me know - just out of curiosity.

    Ok, I'll let you know tomorrow because they will be with me. Yes, the whole pipe is frosted and drips terribly after a few minutes of compressor operation, there is almost a glass of water. And it wasn't like that in the beginning. I don't know what's wrong. I'll wait until tomorrow. Oh, and when I turn it on, for example, after the night, I can hear a terrible noise where the condenser and evaporator stops after about 15 seconds. And even louder after switching off, e.g. after an hour of work.

    Added after 4 [hours] 7 [minutes]:

    Oh, thanks for the measurements. Mine is only 18° but at 23° in the room it was 13° cold. And now at 28° in the room it gives 23° outside.

    Normal because there is probably one engine and to the evaporator and to the condenser, i.e. there are two fans on its axis, disassemble the equipment and see what it looks like.

    Hello, there are two engines. And in the instructions they write "during cooling, heating and ventilation, the discharge pipe must be permanently connected, only in the drying mode it is recommended to remove it." So is it normal for this model to be like that?

Topic summary

✨ The discussion revolves around the inadequate cooling performance of a Blyss 1.1kW portable air conditioner, which the user reports is only able to cool the air by 1-2 degrees compared to the room temperature. Despite being under warranty, the user is concerned about potential issues such as low refrigerant levels or gas leaks. Responses suggest checking for refrigerant leaks, the condition of the evaporator and condenser, and the possibility of clogged capillaries. Ultimately, the user successfully claims a warranty replacement, receiving a new unit that performs well.

FAQ

TL;DR: A healthy 1 kW portable AC delivers supply air 6-10 °C cooler than room air [DOE, 2020]; "Low delta-T means refrigerant loss" [Elektroda, radekklimat, post #10947995] If you only see a 1-2 °C drop, file a warranty claim. Why it matters: Early detection prevents compressor damage and voided guarantees.

Quick Facts

• Typical supply-air drop: 6-12 °C below ambient for portable units [DOE, 2020] • Normal exhaust temperature: 40-55 °C when charged correctly [Carrier, 2019] • EU legal warranty: 24 months on consumer appliances [EU Directive 1999/44/EC] • A 10 % refrigerant loss cuts cooling capacity ≈20 % [ASHRAE, 2018] • Transport upright; if laid flat, wait 24 h before start-up [LG Support]

Why does my Blyss 1.1 kW portable AC cool only 1–2 °C?

The unit lacks sufficient refrigerant or has a blocked capillary. Both faults cut heat transfer, so supply air barely drops [Elektroda, radekklimat, #10947995; #10951344].

What field signs confirm a refrigerant leak?

Look for frost on the evaporator inlet, lukewarm exhaust air, and an overheating compressor casing (>70 °C) [Elektroda, sirkubax, post #10948097] A pressure test by a technician confirms the diagnosis.

Is refrigerant loss within the first year covered by warranty?

Yes. EU law treats any failure within 12 months as manufacturing-related unless the seller proves misuse [EU Directive 1999/44/EC]. Blyss authorised service swapped the whole unit under warranty [Elektroda, sirkubax, post #11014139]

Can a clogged capillary mimic low-gas symptoms?

Yes. A partial blockage throttles flow, causing frost before the capillary and warm air after it [Elektroda, radekklimat, post #10951344] Technicians clear or replace the tube.

How hot should the compressor or condenser feel?

Surface temperatures of 45–60 °C are normal during cooling [Carrier, 2019]. If you cannot touch the shell for more than 2 s, suspect over-pressure or low airflow.

How much condensate water per hour is normal?

Portable units can pull 0.3–1.5 L h⁻¹, depending on humidity and load [DOE, 2020]. Gathering 1 L in 3 h, as reported, falls within the normal range [Elektroda, Misiek85, post #11000907]

What is the correct way to drain water from Ladycook LPC-SP09?

Open the rear flap, slide out the condensate tank, and empty it. For continuous drainage: 1. Remove lower rubber plug. 2. Attach the supplied hose. 3. Route to a floor drain [Elektroda, radekklimat, post #11002910]

Does transport orientation affect performance?

Yes. Oil can leave the compressor when the unit lies flat. Always move upright; if it was horizontal, let it stand 24 h before use [LG Support].

Is 48 dB(A) too loud for watching TV?

48 dB(A) equals normal conversation at 1 m. Most users can still watch TV at moderate volume, but night-time use may disturb light sleepers [WHO, 2018].

How can I quickly test my AC before sending it in?

  1. Measure room and supply-air temperatures after 10 min on MAX. 2. Feel exhaust air; it should be hot. 3. Inspect evaporator inlet for frost. If delta-T <5 °C or exhaust is only warm, contact service.

What room size can a 3.5 kW portable AC cool?

A rule of thumb is 130 W m⁻². A 3.5 kW unit handles about 27 m² of well-insulated space [ASHRAE, 2018].

Edge case: What happens if the unit keeps running with low refrigerant?

The compressor overheats and may seize, leading to total failure. Replacement costs exceed €200, often more than a new budget unit [HVAC-Check, 2021].
