    Hi.
    I have air conditioning installed in the block. Outdoor unit on the balcony, drainage to the bucket. (2nd floor, there is no question of putting the pipe outside the balcony, there are no gutters within reach, currently no possibility of draining (pumping out) the condensate to the kitchen or bathroom (maybe someday generalce you could run a tube in the bathroom floor). Simply at this point, the bucket is the only (known to me) way out.
    I like to combine and I decided that since the outdoor unit is blowing with hot air, I found that I would check the evaporation efficiency. Briefly writing I did as shown in the picture below: I put the end of a tetras diaper into the outlet of the condensate tube (it perfectly collects moisture when wiped) and hung it ~ 50 cm in front of the air outlet with the unit. outside, putting the rest in the bucket. I admit that I have not yet measured the efficiency of this solution (due to lack of time), but the fact is that the water in the bucket arrives much slower. Not only that - for example yesterday morning there was ~ 4 cm of water in the bucket, the air conditioning was not turned on all day (there was no need to do so) and the bucket was dry until the evening.
    And here I have questions for professionals or imaginative guests (or both :) ): Are there any condensate evaporation systems used in professional air conditioning systems? (I've heard of sputtering but missed evaporation.)
    If I wanted to make a slightly better and more durable version of such an evaporator, do you have ideas how to possibly make it and from what material?
    At the moment, I have an idea to hang this tetra in such a way as to maximize its surface. wavy like a curtain (vertically) or in some way (e.g. on strings) horizontally. horizontal folds should be better as they will extend the vertical water path giving more time to evaporate.
    Please note that I do not want to use the outdoor unit cooler for water evaporation / disposal. I don't want to "interfere" with it.
    What do you think about such a "screwed up" idea? :-) .

    Unfortunately not an option (neighbors and stuff).

    Interesting idea!

    Yes, such systems are used in refrigeration furniture. Instead of a diaper, there is something like a sponge. Air is sucked in through the sponge.

    I tested my owned today solution . In half an hour with naked 391 g of water dripped into the tubes and released after a rag it accumulated 269 g, which is 30% less. Today I also bought a balcony pot and spread out the rag, increasing the area more than twice. I have not fully tested this solution yet, but there was no water in the pot for several minutes of work. Now it remains only to wait for another hot day. If this solution works, I have an idea how to do it a bit more professionally .
    This is what version 2 looks like:

    Release the tube on the condenser fins (you can bend them a little for this need), there is hot metal and high airflow - it will evaporate instantly ;)

    Great idea. As soon as the water evaporates, the efficiency of the device will increase.
    I would only suggest pouring the water through a sort of collector mounted on top of the condenser.
    Such a gutter with holes. The water will run in thin rivulets over the fins and will be sucked into the condenser. Buttonholes must be a lot or a brush.

    It is no interference. And so it rains on her.
    With the rest of the heating, water will flow from the outdoor unit anyway, because it is defrosting every now and then.

    We know that you proposed - there is a mass of Klim that is made like this - apparently the idea has been known for a long time.
    There is no interference here - the outlet of the tube should adjoin the lamellas (I would press it into the lamellas), and the water will be drawn in by the fan. You can make a collector that disperses water over a larger area - it is a matter of imagination and manual skills.

    Usually everything is in the housing, so bringing the tube would require a small fit of the housing by drilling a hole in it.

    Nothing needs to be drilled, and what for? You can use the screw holes for the cover fastening with the rest.

    Have you read

    Outdoor unit on the balcony, drainage to the bucket.

    Also an ideal situation for "pouring" on the condenser.
    A long, narrow brush would probably be best. Like for the door downstairs, but with long bristles. A sheet of metal, profiled to it, is screwed so that it constitutes a gutter at the top and below it touches the brush. Something like a question mark (?) In a cross section.
    Such a brush can be attached from the back even with adhesive tape or better with a long rubber band covering the entire cross-section of the air conditioner.
    It's easy to take it off in the winter, and you're in trouble.
    However, when heated, it will still flow from the outdoor unit, and this water is much more difficult to catch. It can also drip from the balcony to the neighbor below.

    ----------
    Apply. Evaporation with a heater. For example, in large crane air conditioners that run with pig iron ladles through the steelworks, they serve the operator's cabin and the electrical switchboard room.

    I'll make the dig of the decade, but all you need to do is spray this water in front of the outdoor unit cooler. The moisture should help to cool the outdoor unit, which should translate into greater efficiency. Patent from indoor air conditioners. The easiest way is to use an ultrasonic "humidifier" :D It gives a mist, not a drop.

    In case you need to get rid of the condensate and can't store it, the easiest way is to use a "fogger".
    For example, such a WIPCOOL P15J costs ~400pln, has a nozzle at the end which sprays a mist, and what you do with it is your business.
    Mostly you put the nozzle outside the balcony and the water mist is simply blown away by the wind, or you can direct it at the condenser, so that the running unit draws it in and mostly cools the exchanger, turning it into steam.

    If you really want to play around, because 4 hundred dollars is not a lot of money, there are "battery washers" on a Chinese website that contain a pump that can generate 8-15bar of pressure, then you put it on the nozzles and off you go!
    Remember to drain the water before winter

    The method of solution obviously depends on the amount of condensation.
    Professional system - not cost-effective, we also do not know the size of the balcony in question ;) .
    The unit sucks the air in from the wall (from the back) if there is room - a 'home-made' solution sometimes just a simple bowl/tray with an ultrasonic humidifier at the back of the unit - the mist generated by the transducer will further cool the condenser.
    I have not personally tested such a solution or the durability of the head in the absence of condensate (water) - I have only heard of trials - it supposedly works (with the indication of "supposedly") in cooperation with a liquid level sensor.

Topic summary

✨ The discussion addresses the challenge of condensate disposal from a split air conditioning system with the outdoor unit located on a balcony without external drainage options. The user currently collects condensate in a bucket and experiments with evaporation by placing a moisture-absorbing rag (tetras diaper) near the hot air outlet of the outdoor unit to enhance evaporation efficiency. Various suggestions include directing condensate onto the condenser fins or radiator to utilize heat and airflow for evaporation, using a collector or gutter to spread water thinly over the fins, and employing small heaters or ultrasonic humidifiers/foggers to convert condensate into mist or steam. Professional systems sometimes use heaters for evaporation, especially in industrial applications. The idea of spraying water mist in front of the outdoor unit to improve cooling and efficiency was also proposed, with commercial foggers like the WIPCOOL P15J mentioned as practical devices for outdoor misting. The discussion highlights the balance between practical installation constraints, neighbor considerations, and maximizing condensate evaporation without external drainage infrastructure.

FAQ

TL;DR: Balcony AC condensate can be evaporated; a DIY wick cut bucket fill by 30% in 30 minutes, “30% less,” near the outdoor airstream. Options include fin‑wetting, foggers, ultrasonic mist, or small heaters, and plan winter drain‑down and neighbor‑friendly misting. [Elektroda, Bartess, post #18039629]

Why it matters: For apartment owners with balcony outdoor units and no drain, this shows clean, low‑nuisance ways to handle condensate.

Quick Facts

How can I evaporate AC condensate on a balcony without annoying neighbors?

Use a wick evaporator in the outdoor airstream. In testing, bucket fill fell 30% in 30 minutes (391 g to 269 g). Increase surface using folds or a shallow planter. This cuts visible drips and keeps water contained on the balcony. [Elektroda, Bartess, post #18039629]

Do pros actually evaporate condensate instead of draining it?

Yes. Industrial systems evaporate condensate with resistive heaters where drainage is impossible. “Evaporation with a heater.” This approach serves crane cabins and electrical rooms. For balconies, scale the heater and ensure safe mounting and power. [Elektroda, gag70, post #18043428]

Will dripping condensate onto the outdoor condenser increase efficiency?

Routing thin rivulets across hot fins evaporates water quickly and can aid performance. One tech notes, “the efficiency of the device will increase.” Use a small gutter with many holes to spread flow. The fan entrains vapor into the airstream. [Elektroda, jack63, post #18041350]

How do I build a simple wick evaporator?

  1. Fix absorbent cloth (e.g., tetra diaper) to the condensate hose outlet.
  2. Hang it in front of the outdoor discharge to get strong airflow across it.
  3. Spread the cloth in folds or over a planter tray to lengthen the water path. [Elektroda, Bartess, post #18038104]

What media works best for evaporation?

Open‑cell sponge or similar foams work well. Refrigeration furniture uses sponge media while drawing air through it to evaporate water. Upgrade cloth to durable foam if sun and wind degrade fabric. Ensure strong airflow through the media. [Elektroda, p.obelix, post #18038242]

Is using an ultrasonic humidifier outdoors safe for this?

It can atomize condensate into a fine mist, limiting drips. A large drop can flood the head and stop mist production. Add splash control and keep the transducer level. If reliability is key, a small heater is simpler. [Elektroda, Anonymous, post #18038237]

What fogger or sprayer setup works, and how much does it cost?

Use a fogger like WIPCOOL P15J (~400 PLN) to spray mist. Mount the nozzle outside the balcony or aim at the condenser intake. DIYers repurpose 8–15 bar battery washers with mist nozzles. Drain hoses and pumps before winter. [Elektroda, vinetu_, post #21593540]

Can I route condensate to the condenser without drilling or “interfering”?

Yes. “There is no interference here.” Press the tube into the lamellas so the fan pulls water in. Add a small collector to spread water over a larger area for faster evaporation. Avoid altering refrigerant components. [Elektroda, Chris_W, post #18041545]

Do I need a pump if my outdoor unit sits above the indoor unit?

If the indoor unit is lower than the outdoor unit, gravity drainage is hard. Install a condensate pump or reroute the drain path. Plan electrical and maintenance access for the pump. [Elektroda, Anonymous, post #18041548]

How much water should I plan to handle on hot days?

Plan for several liters per day. A portable unit filled a 5‑liter bottle in one day. Size your wick, fogger, or drain for peak humidity days to avoid overflow and mess. [Elektroda, Anonymous, post #18038153]

Is condensate safe for watering plants on the balcony?

You can route the condensate into planters to reuse water. Add a diffuser to break drops, protecting soil and minimizing splash. Keep the line clean to avoid biofilm odors near windows. [Elektroda, Anonymous, post #18038153]

What about winter and defrost water?

In heating mode, outdoor units defrost and shed water from the coil. That runoff is harder to collect and can drip downstairs. Remove seasonal add‑ons and manage drainage to avoid nuisance. [Elektroda, jack63, post #18041975]

What’s a low‑power electric approach to evaporate condensate?

Place a small heater by the collection point to accelerate evaporation. A 10 W element is trivial beside a 4 kW AC load. Keep clearances and fire safety in mind when mounting. [Elektroda, Anonymous, post #18038237]

Any tips for balcony etiquette and placement?

Direct mist outside the balcony lip so wind disperses it. Or aim mist at the condenser intake so it is drawn in and evaporated. Always drain the system before winter to prevent damage. [Elektroda, vinetu_, post #21593540]

Which outdoor ultrasonic humidifier is proven for this job?

No specific outdoor‑rated ultrasonic model was confirmed in‑thread. Users attempted a tray plus ultrasonic head behind the unit with a level sensor. For weather resistance, a fogger is often easier. [Elektroda, fadil, post #21595164]
