Description

Design, installation, turnkey delivery of the central cold supply in supermarkets

Refrigerating main lines are intended for creation of artificial cold in the centralized systems of cold supply. Installation of the central cold supply represents the unit allowing to integrate in the general cycle of all consumers of cold with approximately equal temperature. For right choice of the refrigerator it is necessary to execute calculation of heat balance on the basis of the basic data provided by the customer. The choice of system of refrigerating appliances – one of the most important and responsible points in life of grocery store, the warehouse terminal. Quality and safety of products in many respects depends on refrigerating appliances. Important factor is operation and optimum work of the equipment. These installations are widely used for cold supply of supermodels, shops of the average trade area, food warehouses, vegetable - and fruktokhranilishch. One unit can feed both one unit of equipment, and the same equipment connected to the line. As a rule, two main lines – medium temperature and low-temperature are applied to the shopping facility. Respectively, the first feeds all equipment with above-zero temperature, the second – all equipment with minus.
* high reliability and durability due to use of several
compressors
* stop of one compressor not
affects temperature conditions
refrigerating

there is also no equipment need
to interrupt work of all trade
enterprises
* operational expenses decrease
* are excluded noise and raised
temperature in trading floor
* allows to lower expenses on
conditioning in trading floor
* works automatically, does not demand
the intervention servicing
personnel at operation
* it is possible to have to long lines,
at the same time bend angles can be
any.

The industrial refrigerating appliances can be completed with air coolers of different types, portable condensers of air cooling, portable cases of management. On one industrial unit can be established from 1st to 5 compressors (multicompressor main line). The industrial refrigerating appliances are subdivided into five temperature ranges: — high-temperature; — medium temperature; — low-temperature; — skoromorozilny; — polyvalent. High-temperature units are intended for maintenance in temperature camera from +5 °C to +15 °C. Medium temperature units are intended for maintenance in temperature camera from -5 °C to +5 °C. Low-temperature units are intended for maintenance in temperature camera from -18 °C to -25 °C. Skoromorozilny units are intended for maintenance in temperature camera from -25 °C to -45 °C. Polyvalent units are intended for maintenance in temperature camera from +5 °C to -25 °C. The industrial refrigerating appliances are intended for work at temperature surrounding from +5 °C to +43 °C. For work of industrial refrigerating appliances at temperature of surrounding air below -5 °C, installation of "winter equipment" is necessary. "Winter equipment" includes heating of case of the compressor, heating of the control panel, variator of speed of rotation of fans of the condenser. The industrial refrigerating appliances of the closed type are protected by panels from steel with epoxy covering. Excellent efficiency of industrial refrigerating appliances is reached thanks to the orebrenny batteries of condensers and air coolers made of copper and aluminum with carefully picked up surface of heat exchange and obduv. If in the district where industrial refrigerating appliances are installed, there are failures in power networks, it is recommended to install tension monitor. The monitor of tension to provide protection of monoblock against power surges and against distortion of phases. The industrial refrigerating appliances represent the tight system working at coolant – R-22 freon or R-404a. In monoblocks electronic control units and devices of automatic thawing with the subsequent removal of thowing water are installed. Average time of operation of the compressor of monoblock: High-temperature — 65%. Medium temperature — 70%. Low-temperature — 75%. Skoromorozilny — 75%. Polyvalent — 75%. Principle of work of refrigerating system: the compressor compresses coolant vapors up to the condensation pressure, in the condenser hot vapors of coolant are cooled and condensed, giving to warmly cooling air, and then liquid coolant, passing through the filter dehumidifier, receiver and the drosseliruyushchy device, comes to the evaporator where there is its boiling. The formed couples, passing through liquid separator, again are sucked away by the compressor.
