Household kholodoproizvodstva complex
(57) Abstract:Usage: in refrigeration, as it relates to household refrigerators with forced circulation of air in the cooled volume. Essence: in the household holoprotein complex having a heat-insulated chamber, a refrigerating unit with evaporator and a fan, distribution panels with gills holes along the walls with the formation of vertical channels for the passage of cold and warm air, communicated with the accommodation area of the evaporator, insulated Luggage recruited from several independent uniform removable modules, made of rigid insulating material. The number of modules, and hence the useful volume of the complex can be changed at customer's request. The modules are connected Rethimno between themselves and the refrigerating unit, which is made as a separate unified module, through common channels for the passage of cold and warm air and sealing elements. As the working substance refrigeration unit can be used non-azeotrope blends a mixture of halocarbons. One of the modules is designed as Vozduha, 3 Il. The invention relates to refrigeration, and more particularly to a device intended for use in household refrigerators with forced circulation of air in the refrigerated volume and air-conditioning.Known domestic refrigerators with forced air circulation, for example, the company "TOMBA" (Japan) and the firm "COLDSPOT (USA). Small refrigeration units and refrigerated transport. Handbook (Ed. by A. C. M. Bykov Food industry, 1978, S. 54-56).Common signs of refrigerators of this type: fan and air ducts; ribbed evaporator and fan are outside the useful volume of the chamber; a fan channels to blow cold air into the chamber to provide the necessary temperature values; the camera has air distribution system.The main advantage of this type of household refrigerators is the complete elimination of sedimentation frost on the products and the chamber walls. The moisture contained in the air, falls on the finned evaporator, separated by a partition from the main volume chamber that receives dry chilled air. Heating of the evaporator when defrosting has little effect on the temperature to which the several times a day, not removing the frozen products from the low-temperature chamber. This improves the storage of chilled products in the refrigerator, reduces its loss, and also eliminates the extra expense of electricity to drive the compressor of the refrigeration unit, caused by the necessity of Sahelian camera (the Department) and stored products after defrost.As the prototype is set to the fridge for ed.mon. USSR N 943501, CL F 25 D 17/06 containing thermally insulated chamber, a refrigerating unit with evaporator and a fan, distribution panels with holes along the walls with the formation of vertical channels for the passage of the cooled air is communicated with the accommodation area of the evaporator.The disadvantages of refrigerators of this type are:
fixed net volume of the refrigerator, as well as the ratio of the volume of low and medium-temperature cameras do not offer the ability to change these parameters on the request of the consumer and leads to the issuance of standard series refrigerators with different values of useful volume,
significant consumption of the refrigerator due to the fact that the insulated chamber (camera) have a common (usually meta is with different amounts of cells leads to increased production costs, hence, the cost of refrigerators,
the cost of the refrigeration unit is 20-30% of the cost of the refrigerator and, therefore, reduction of the sizes in the direction of greater cooling capacity does not significantly increase, ceteris paribus, the cost of the refrigerators, and with the increase in their productivity (instead of small cars) the influence of this factor is reduced,
transportation of household refrigerators from their places of production to the place of consumption is 50% transportation "air" insulated chambers, which increases transportation costs,
separate manufacture of domestic refrigerators and air conditioners leads to duplication holoprotein units that impairs their adaptability to conditions of limited living space apartments and growth of the cost of their acquisition.The present invention is the improvement of consumer properties of household holoprotein complexes, reduction of material and production costs to make them.To solve this problem in the household holoprotein complex having a heat-insulated chamber, a refrigerating unit with evaporator and a fan, vozduhonosnye vertical channels for the passage of cold and warm air, communicated with the accommodation area of the evaporator, insulated Luggage composed of several independent removable modules. Each module has its own door. The modules are interconnected with refrigerating unit, also performed in a separate module, through common channels for the passage of cold and warm air and sealing elements.As a working agent refrigeration unit used non-azeotrope blends a mixture of halocarbons, the number of vertical channels for the passage of cooled air is provided with separated zones of the evaporator is equal to twice the number of temperature levels of refrigeration.A separate module contains external distribution panels for the production of cold and intake of warm air from the room. In this case kholodoproizvodstva complex can be used as conditioning.This solution household kholodoproizvodstva complex having the General advantages inherent in the units with forced air circulation, allows to obtain a new technical result: the possibility of changing the useful volume of the complex, increasing its function is ü fridge so that he possessed the required amount as the entire complex, and a separate insulated chambers. In addition, the ratio of the useful volume of low and medium temperature chambers during operation can be changed, for example, depending on the quantity of processed products.Linking household refrigerator based on the needs of each individual consumer, allows to reduce the total consumption of the unit.Possible specialization of enterprises for production of only uniform refrigeration unit. The production of insulated chambers can be arranged on specializirovannih enterprises, which will considerably reduce inventory and transportation costs.The availability of each module its doors allows to reduce the heat leakage when opening, to reduce the load on the compressor, to reduce energy consumption.Significantly improve the consumer properties of a household refrigerator, and also to facilitate the management of them might be the case if the working substance refrigeration unit to use non-azeotrope blends a mixture of halocarbons (e.g., refrigerant R (R 12-R 22-R 142) THE 6-02-1226-82) Drammeh T. S. Silin L. B. Ilchenko L. I., "Experimental Jerusalem. Boiling such a cooling agent in a wide temperature range allows you to organize separate streams of cooled air in the insulated chamber with an optimum for each volume with temperature. It will protect from obmorazhivanija products in the medium-temperature chamber (vegetables, fruits), will facilitate the management of household refrigerator because of the presence of independent streams of air, will reduce energy consumption by choosing the optimal working substance and the percentage of individual components in it. In this technical solution, the number of vertical channels for the passage of cooled air is provided with separated zones of the evaporator is equal to twice the number of temperature levels of refrigeration.The presence of separate vertical channels connected with his area of the evaporator allows individual module constructively to perform like an air conditioner. When this distribution panels with holes out of band with the release of cold and intake of warm air from the room.This eliminates duplication of refrigeration units, increasing unification of refrigeration equipment (compressors, heat exchangers and so on), allowing reduced consumption of materials and production costs, improve consumer properties of household holoprotein complexes.In the analysis of known technicalites and inventive and can improve the consumer properties of household holoprotein complexes, to reduce the consumption, production costs, and hence their value.In Fig. 1, 2 and 3 present the technical solutions proposed residential kholodoproizvodstva complex, respectively, under item 1, 2 and 3 formulas of the present invention (the General view kholodoproizvodstva complex and its variants).In Fig.1 shows the proposed residential kholodoproizvodstva complex consisting of separate modules (refrigeration unit 1, nizkotemperaturnyh cameras 2 and 3) and the cover 4 is installed at each other and interconnected through common channels for the passage of cold and warm air (respectively, 5 and 6) and the sealing elements 7.
