In this article we will analyze in detail each stage of the transformation, starting with the preparation of tools and ending with the final setup of the plant life support system. You will learn which nodes require special attention when removing, how to organize an effective air circulation inside a closed volume, and what mistakes beginners in this business most often make. Proper implementation of the project will allow you to enjoy lush flowering all year round, regardless of the conditions in the apartment.
Necessary tools and safety measures
Before starting the active phase of work, it is necessary to prepare the entire arsenal of tools, since the process can take several hours. The main tool will be screwdriver with a set of bits, since most fasteners in modern and old models are made in this format. You will also need pliers, wire cutters for cutting wires and tubes, as well as protective gloves to avoid cuts from sharp metal edges.
Particular attention should be paid to protecting the respiratory system and eyes. Old units often contain dust, mold, or insulation residues that can be toxic. If you plan to work with refrigerants or foam, the presence of a respirator is a mandatory requirement. You should not neglect these measures, since health is more important than speed of work. safety glasses is a mandatory requirement. You should not neglect these measures, since health is more important than the speed of work.
- 🛠️ A screwdriver or a set of screwdrivers with various attachments for removing panels.
- 🔧 Wire cutters and pliers for working with wires and tubes.
- 🧤 Thick construction gloves and a dust mask.
- 🔦 A powerful flashlight or headlamp for illuminating internal hard-to-reach areas.
⚠️ Attention: If the refrigerator is still plugged in or contains refrigerant, never cut through the cooling system pipes without first releasing the gas in a ventilated area. Residual pressure may cause oil splashing or injury.
After collecting tools, make sure the work area is well lit and ventilated. Organize all your tools in the order of their intended use to avoid wasting time searching during disassembly. Preparation workplace is the guarantee that you will not lose anything and will be able to neatly put away the removed parts.
Primary preparation and dismantling of doors
The first step in the process of how to disassemble a refrigerator for flowers is to remove the door. This is necessary not only for ease of access to the insides, but also for safety, to prevent accidental slamming of a heavy structure during operation. In most models, the hinges are located at the top, but there are options with bottom fastening or hidden mechanisms.
First, remove the decorative plugs from the hinges, if they are present. Usually they are pryed off with a thin screwdriver or knife. Then carefully unscrew the mounting bolts holding the top hinge. At this stage, it is advisable to enlist the help of an assistant who will hold the door until you completely unscrew the fasteners. Heavy models can weigh up to 30-40 kg, and dropping them on your foot will be extremely unpleasant.
After removing the top hinge, the door can be easily removed from the bottom axis. If the model is equipped with a complex system closers or electronics in the door, first disconnect the wire cables after photographing their connection. This will come in handy if you decide to use some controls in the future.
☑️ Removing the refrigerator door
Models with a system No Frostdeserve special attention, where air ducts can pass through the doors. In such cases, you need to be extremely careful not to damage the plastic channels if you plan to use them to organize ventilation in a future greenhouse. Maintaining the integrity of the internal elements of the door can be a key point for creating efficient aerodynamics aerodynamics
Removing internal equipment and shelves
Once access to the internal volume is open, it is the turn to remove all removable elements. Shelves, drawers for vegetables, trays on the door - all this needs to be removed. In older models, the shelves may be mounted on guides, which it is also advisable to dismantle in order to obtain the cleanest possible space. Plastic elements are easy to clean and can be used as trays for pots in the future.
Then you should move on to more complex elements, such as the evaporator and condensate drainage system. If the refrigerator is a freezer or combination refrigerator, there may be defrosting heating elements inside. They must be carefully disconnected from the wiring. Often the wires are hidden in corrugation or attached to the walls with clamps that need to be cut or unfastened. It is important not to damage the internal lining if you plan to maintain the aesthetics internal volume.
| Element | Mode of fastening | Tool for removal | Possibility of reuse |
|---|---|---|---|
| Glass shelves | On plastic supports | Hands | High (pallets) |
| Boxes for vegetables | On guides | Hands/Pliers | High (capacity) |
| Lighting lamp | Screws/Latches | Screwdriver | Medium (light) |
| Control panel | Screws/Clips | Phillips screwdriver | Low (spare parts) |
When dismantling the internals often reveals hidden fasteners or elements that are not visible during normal use. Carefully inspect the corners and back wall. Sometimes additional sensors or fastening elements may be hidden there compressor (although the compressor itself is located outside). Accuracy at this stage will avoid unnecessary noise and rattling in the future, when the refrigerator starts working as a display case with fans.
What to do with odors?
Old refrigerators often have a persistent smell of food or mold. To eliminate it, wash the insides with a solution of soda or vinegar, then leave the door open for several days. You can use activated carbon or coffee in an open container to adsorb residual aromas.
Removing the compressor and refrigeration circuit
The most labor-intensive and critical step is removing the cooling system. If the refrigerator is old and you plan to use it only as an insulated cabinet, the compressor, condenser (black grill on the back) and the evaporator inside must be removed. Start with the back panel that covers the compressor. Remove it by unscrewing the perimeter screws.
Before disconnecting the pipes, make sure that the refrigerant is completely released. In modern conditions, it is better to do this with the help of a specialist or special equipment, but in everyday life they often simply let the system stand turned off for a long time or carefully bite the tube in a well-ventilated place. After releasing the pressure, you can cut the copper tubes with wire cutters. Be careful: the tubes may leak compressor oilwhich is difficult to clean.
- 🔌 Disconnect the refrigerator from the power supply and remove the back cover.
- 🔪 Break through the copper tubes connecting compressor with condenser and evaporator.
- 🔧 Unscrew the mounting bolts holding the compressor to the frame.
- 🧹 Remove the heavy unit and dispose of it according to the rules.
After removing the compressor, it is necessary to remove the evaporator from the inner chamber. In older models, it may be frozen into the back wall or attached to it. If the evaporator is aluminum and thin, you can carefully bend it and pull it out, being careful not to damage the internal plastic. If it is integrated into the wall (foamed), then there is no point in cutting it out - it is better to leave it as is if it does not interfere with the installation of shelves for flowers. The main thing is to remove all unnecessary protruding parts.
⚠️ Attention: Refrigerants used in refrigerators (freon) can be harmful to the environment and the ozone layer. Don't let them out in closed spaces. Try to hand over the dismantled components to collection points for scrap metal or electronics.
Organization of lighting and ventilation
After cleaning the housing, it is time for technical modernization. Light and air are critical for plants. Standard refrigerator lighting, even if it works, is usually too dim and has the wrong spectrum. You will need to install phytolamps or full spectrum LED strips. It is better to mount them on the ceiling of the chamber or on special brackets that can be installed instead of removed shelves.
Ventilation is the second key point. In a closed space without air circulation, condensation quickly forms, which leads to rotting of plants. To solve this problem, computer coolers (120x120 mm) are used. One or two fans are installed at the top of the chamber to mix the warm air that rises. Power can be provided from an old refrigerator power supply (if it is 12V) or from a separate adapter.
To lay wires through the walls of the housing, use rubber bushings or bushings so as not to damage the cable insulation on sharp metal edges. All connections inside must be reliably insulated, since the humidity in a flower display will be higher than in a regular room. Safety of electrical wiring in conditions of high humidity - priority number one.
If you plan to grow particularly moisture-loving species, you can consider installing a small humidifier ultrasonic type air, but then the ventilation system must be configured so as not to create drafts, but to ensure the movement of air masses. The balance between humidity and air exchange is selected experimentally for each type of plant.
Final assembly and decoration
When the technical part is completed, you can move on to the creative stage. The inner walls of the refrigerator are usually white or colored, which reflects light well, but for aesthetics they can be covered with mirror film or foil. This will enhance the light and visually expand the space for plants. In place of the standard shelves, you can install wooden or glass shelves, securing them to new brackets.
The refrigerator door is an excellent place to place tools, control panels, or even additional flower pots, if the design allows. If the refrigerator has an external control panel, it can be reprogrammed or used to display the current temperature and humidity inside the display case by connecting external sensors. This will turn your homemade product into smart greenhouse.
The appearance can also be updated. The old case can be covered with self-adhesive film to imitate wood, stone, or left in a retro style if the design of the refrigerator allows it. Some craftsmen even change door handles to more modern ones or, conversely, vintage ones in order to fit the object into the interior. The main thing is that the final result pleases the eye and creates ideal conditions for green pets.
Is it possible to use an old refrigerator without removing compressor?
Technically it is possible if you plan to grow plants that require low temperatures (for example, some types of orchids or for storing seeds). However, a running compressor creates vibration and noise, and also takes up useful space inside the chamber. For a regular indoor greenhouse, it is better to remove it.
What plants are best suited for growing in the refrigerator?
Orchids (phalaenopsis), Saintpaulias (violets), succulents (with good ventilation) and tropical vines are ideal. These plants love the stable humidity and temperature that a sealed housing provides.
Do you need to make holes in the housing for ventilation?
Yes, definitely. Even with internal fans, the air must be renewed. Usually, two holes are made: one at the bottom for the influx of fresh air and one at the top for the exit of exhaust air, often installing dust filters in them.
How to deal with condensation on the door glass?
Condensation is a sign of high humidity. Reduce the number of sprays, increase the ventilation power, or install a small fan inside aimed at the glass surface of the door to blow away the moist layer of air.
Is it safe to use old plastic refrigerator elements?
Yes, food-grade plastic used inside is safe for plants. However, if the plastic has turned yellow or has signs of destruction, it is better to replace it with new materials to avoid the release of harmful substances when heated by lamps.
