PROBLEM DESCRIPTION

A contemporary fridge is the second-largest user of electricity (13.7%) in the household.

It has a huge environmental impact as it gives out CFCs leading to ozone layer depletion.

Moreover, it occupies precious 1,5 cubic meters of kitchen space.

How was the food refrigerated and kept fresh before a fridge has been introduced at the beginning of the 19th century?

Is a comtemporary fridge, this energy-hungry giant is the only solution of a safe food storage problem?

What is passive refrigeration and how the traditions of our grandfathers can be applied to nowadays?

TRADITIONAL REFERENCE SOLUTIONS

Before the fridge has been introduced, people used different other methods to keep the food fresh. For example, in cold regions of Russia the food was stored larders constructed under the ground and surrounded by blocks of ice, cut out of the frosen lake.

Preserving food by canning, drying, salting, or pickeling, or, in the case of grains, by turning it into alcoholic drinks, - is another way of storing, even in hot climates.

Nowadays traditional (or passive) refrigeration which used natural cold to keep the food fresh, is unfairly substituted with electrical one.

CONTEMPOPARY REFERENCE SOLUTIONS

Contempopary food storage solutions mostly come from the concept of using solar energy.

For example, External Refrigerator for Electrolux

by Nicolas Hubert. Fixed directly on the outside wall of residential buildings, the concept is an elaboration on a way of life in northern China where food is kept on balconies in the winter to save space and energy. During cold seasons and at night, the low external temperatures are used to provide the right climate for items in the fridge. During warmer weather, the sun is used to transform light into energy through solar panels.

Contempopary architects build up and cover the whole buildings with solar elements in order to reduce electric energy consuption and use an alternative source.

CONCEPT AND INSPIRATIONS

Keeping in mind the passive refrigeration idea, it was decided to design a conceptual refrigerator for household use.

During the creation process the following features of a new product have been taken into consideration: 1) the fridge should now occupy much space - hang it outside; 2) outside it should not disturb the view make it look like a balcony, provide space for a garden; 3) inside there should be the same amount of space as in the normal fridge; 4) should be easily reached by a child - not high;

5) find some natural element for shape inspiration - for example snowlake; 6) be careful with materials - and outside fridge should not let the building freeze.

PRODUCT DESCRIPTION

Considering all mentioned above, a new conceptual product - OUTSIDE FRIDGE - was created. It is a space and energy saving product. It does not occupy space on the kitchen because it is fixed into the wall under the window and mounted outside.

Due to such a position, an OUTSIDE FRIDGE reduces electric energy consumption in a household because it uses natural cold in winter or in cold climate regions and solar energy in summer or in hot weather climate.

The OUTSIDE FRIDGE has 3 compartments: two doors and one drawer, which is a freezing compartment. Such a division allows to have the same amount of space as in a normal fridge.

PRODUCT IN USE: INSIDE

The OUTSIDE FRIGDE has the dimensions that easily fit the niche under the window on every kitchen. Thus, it saves the space and can be easily reached even by a kid or phisically disabled.

PRODUCT IN USE:OUTSIDE

The top part of the fridge, which is protruded from outside can be used as a base for flower pots or even for the box with fertile soil, where you could grow some summer vegetables or herbs.

COLORS AND TEXTURES

An OUTSIDE FRIDGE is designed in a way that gives you an opportunity to choose the color and texture for the fridge and whether make match to the color of your kitchen firniture, whether outstand.

The color palette of an OUTSIDE FRIDGE depends on your imagination only. The cover is implemented in plastic, so you can choose any color according to existing Pantone Color System.

Technical drawing 7: BACK VIEW

The back part of the OUTSIDE FRIDGE is covered by solar panel which consists of reflecting solar elements. The solar panel is provided by 3VP Group Solar and consists of triangular shaped solar elements and mirrors, that help to reflect and collect the sun from vertical flat surfaces. All the engineering ang fixing details will be provided by the supplier.

The solar panel can be expanded from the fridge and mesh onto the perimeter wall and deliver an additional aesthetically pleasing effect on the building. You can not only choose the number of solar panels to decorate your window but receive additional portion of passive energy.

INSTALLATION DETAILS

To install the OUTSIDE FRIDGE under the window of your kitchen or in any other preferable place, 1) cut the wall with perforator and saw considering the outside dimensions of the fridge +1cm width and 1 cm depth for the fixer (see the wall section) leaving minimum 5 cm wall from the floor; 2) insert the base of the fridge into the whole, filling the gap between wall and concrete with polyfoam: 3) fix the base to the wall with strong metal bolts; 4) cover the wall and the base of the fridge with plaster, let it dry; 5) apply the finish; 6) adjust the shelves and doors according to your preferences.

Before installation of the product the appropriate architectural structures have to be consulted in order to receive a permission to make changes in an existing surface of the building.
