How to make a refrigerator freezer: the creation and manufacturing of other embodiments of the freezing device.

Often when buying a new refrigerator, the old still remains operational and continues to serve their owners in the far corner of the apartment or villa as a backup option. If the owners need arises for additional space for frozen foods such artifact sometimes becomes a contender for being reworked in a large freezer.

The following will be discussed on how to do from a conventional refrigerator freezer unit on its own.

The principle of operation of the freezer

Before starting the construction of a freezer cabinet, should carefully examine the principle of its operation.

A refrigeration unit operates by analogy with the air conditioning, which removes the heat in a small, thermally insulated space. The transfer device is carried out from the inside heat refrigerant, as is usually used Freon. It is a closed loop and passes from the liquid to the gaseous state with the absorption of heat, and vice versa - with the thermal release of energy. AT

azhnymi freezer units are: condenser, compressor, evaporator, a thermostat, a tube forming the circuit, and, actually, the internal space of the refrigerating chamber.

heat cycle takes place according to the following algorithm.

1. The refrigerant is in a liquid state, when released into a low pressure evaporator begins to boil (vaporized). This process occurs upon absorption of a large amount of energy - thus, the temperature in the chamber is reduced.
2. After that freon in gaseous form is injected compressor and enters the condenser. Under the action of high pressure it liquefies. The heat released during this process, which is output to outside the device in the condenser cooled by ambient air.
3. Thereafter, the liquid material enters the capillary tube and fed back to the evaporator, where the pressure falls off sharply. The cycle begins anew.
4. If the temperature falls below a predetermined level for a couple of degrees, the motor is temporarily switched off. When it rises by 2-3 degrees higher, it starts again.

How to make a refrigerator freezer

This option is the easiest to create the freezer with his hands.

First of all it is necessary to disassemble and remove the freezer compartment evaporator. After that you should insulate the interior space, which will become a new freezer. After that you need to deploy the evaporator and secure it on the back of the freezer. Responsible point is the next step that you need to choose the right location for the temperature sensor. Depending on the choice of the freezer will maintain the desired temperature with a certain accuracy.

After installation of the sensor must ensure tightness of the formed chamber, and check the refrigerant circuit to perform refueling, if necessary.

ATTENTION! For the diagnosis of the refrigerant circuit and refilling freon is necessary to use special tools. To avoid the integrity of the loop must be very careful to make manipulation of the capillary tubes, avoiding their excessive bends.

At the last stage should include an upgraded unit and test it in the work.

IMPORTANT! Efficiency alone converted the freezer is substantially worse than that created in the industrial environment, so its energy efficiency is lower and consumption of electricity - more.

What else there are options for the freezer with his own hands

In addition to the conversion of an old refrigerator, there are many options for creating freezers that require varying levels of skill, tools and materials. Consider some of them.

A small room in a freezer

Along the perimeter of the room set the crate of timber. Thereafter stack reflective material. Formed crate cells densely fill insulation thickness of at least 10 cm. All cracks and joints must be sealed by aluminum tape. After that, the walls are covered with thin sheets of galvanized metal generated seams securely sealed. freezing rooms cooling nucleus can serve as a regular candy bar. Selects the optimum location for the temperature sensor, which is connected to the automatic control system. The final touch - the production is well insulated door which tightly adjoins the box in the mixing condition.

Freezer of sandwich panels

One of the low-end to create a chamber for freezing large capacity can serve as a design based on sandwich panels. Principles of the organization of work are the same as in the case of the room arrangement described in the preceding paragraph. Sandwich panels are collected in the construction of desired size and configuration in accordance with their standard installation rules.

The establishment of such freezing facilities need to monitor the absence of thermal bridges - thermally conductive bridges between the outer and inner lining of engineering design.

To combat the formation of thermal bridges at joints in the construction of the corners makes a special slot inside corner elements in the places they are released into the environment.

Measures against thermal bridges must also be carried out at the junction of refrigeration sections supporting different temperature levels.

Door as in equipment rooms with main walls, there should be a quality lock and insulation. It is best to use for this purpose a special polyurethane foam termodver.

Other options for freezers

Listed below are some ideas that can form the basis for the manufacture of homemade freezer systems:

• use as a freezer space for housing the transport container;
• arrangement of the warehouse;
• for the manufacture of a chest freezer small, cooling the contents to a moderate temperature (-10 ⁰C), it is possible to use Peltier elements;
• creating indoor cold condenser operating on the principle of the ice, e.g., the use of basements, belted closed Pipeline system with refrigerant (e.g., kerosene), which concentrates in cold winter season and maintains the low temperature level in warm season.
