    Hello, I came up with such an idea to construct a home air conditioner. What should the layout look like, how do you control the temperature? Is it for a room with an area 18m2 such a deal will give advice?
    compressor - from the fridge
    Condenser -2xAir conditioning condenser 605mm x 400mm
    Dehumidifier filter - I have a new one from audi)
    Expansion valve -From audi a4
    evaporator -1xAir conditioning condenser 605mm x 400mm
    Service valves - new from the store (PLN 38 / unit)
    External fan .- 2x 25W / 100-230V engine 1300 rpm + 2x propeller from the car fan + speed control.
    Internal fan -6x fan 120 x 120 mm 12V ~ 2000RPM (such a computer, because quiet :)
    I will use a fi8 copper pipe for connection (such as from lpg)
    The question is, will it work at all? How to make temperature adjustments from a fridge thermostat?

    None of this will be - the compressor from the refrigerator has too little efficiency

    What if I used a compressor from a normal air conditioner? for example:

    You will get something out of this, the compressor is concrete. If he can and will, he can cool the room. But you have to play with it as you know what to do, how it should be. Worse as it will not work properly. Will you lose the used current, not to mention the cooling factor ?? :|

    Well, I bought this compressor for a ridiculous amount of 250 PLN with shipment ;) will come and put the whole thing together :) . And as for the factor just for the proverbial colleague who deals with air conditioning will give me a deal. I will add photos from all construction pozdr.

    Remember that you can not use accidental gas for a given compressor, you must check on the compressor for which gas you can use it.

    None of this will come out because the compressor is not on r134 and randomly selected elements. If this is the case, we install the entire air-conditioning system from one car or a 230V mains conditioner. Anyway, now the air conditioners are so cheap that it is not worth the DIY to do. Secondly, how does the expansion valve, how do you connect aluminum with copper, do you have more than 0 concepts of factor conversion, system lubrication and temperatures? Now, a lot of people are assembling splits and for 3-4 ounces you can buy a functional air conditioner with a spiro tube for performance like it has to be, not this scrap of scrap.

    Profitability is one thing but satisfaction is the other. I, too, when I find some time, I will play with myself in such a self-made way.

    To the author:
    Do not play the Macayev method, the basis is calculations. They once taught you that you take a circa 40W / m3 of cubic capacity plus 40W per one physically inactive person, plus about 20% more if there are windows to the south, and 10% if east / west. Knowing these kW you can have fun in the selection of equipment.

    A CONDITIONER uses a lot of electricity. The smallest (from the secondary market) is about 1kWh per hour.
    Counting that the whole will cost you 300 PLN, the current for this is only 300 hours of cooling.

    Proposal. Poor / poor (efficient) climate (samoróbka) will kill operating costs.
    I also recommend to buy a used one - it will be definitely more efficient and ... will earn on yourself in relation to the self-made.

    It's hot as hell, I'll add the idea of the perpetuum mobile air so half-joking half seriously.
    For fun you need a gas cylinder, an indoor unit splits, some gas stove, a large pot and a set for enriching liquids.
    And now a simplified scheme:
    We connect the cylinders to the splice (I assume that the expansion valve is built in Split), after the expansion the gas goes to the stove where it produces beverages or biofuel.
    Of course, I do not intend to submit it, but as a layman, I wonder where the puzzle is a mistake, because it would be too easy to work?

Topic summary

The discussion revolves around the feasibility of constructing a DIY air conditioning system for an 18m2 room using various components, including a refrigerator compressor, car air conditioning condensers, and fans. Initial skepticism is expressed regarding the efficiency of a refrigerator compressor, with suggestions to use a standard air conditioning compressor instead. Participants emphasize the importance of proper component selection, including refrigerant compatibility and system calculations for cooling capacity. Concerns about energy efficiency and operating costs are raised, with recommendations to consider purchasing a used air conditioner for better performance. The conversation also touches on the technical aspects of connecting components and the need for accurate calculations to ensure effective cooling.
