50 years in refrigeration engineering. For a long time and for a long time
摘要
At the end of the 1940s, the question arose of the need for widespread introduction of artificial cold in various sectors of the country's national economy. The refrigeration engineering industry was given the task of further developing and improving the designs of refrigeration machines and apparatuses, expanding their range with the use of new refrigerants and automation equipment.
In accordance with the Decree of the Council of Ministers of the USSR of November 14, 1949 No. 5226, it was decided to establish in 1950 the Central Design Bureau of Refrigeration Engineering (TsKB KhM) in order to develop modern refrigeration equipment, as well as to reconstruct the refrigeration engineering plants.



Activities of JSC "Vniiholodmash-Holding" to fulfill Russia's international obligations in the field of refrigeration technology related to the protection of the ozone layer.
摘要
The year of the 50th anniversary of the founding of JSC VNIIholodmash-Holding coincides with the 15th anniversary of the signing by the Soviet Union of the Vienna Convention for the Protection of the Ozone Layer.
OJSC VNIIkholodmash-Holding is the leading organization in refrigeration engineering, under the leadership of which work is being carried out in Russia to prepare for the transition to ozone-friendly technologies in this area of technology.
The work covers the areas of research, design, manufacture and operation of refrigeration equipment and is carried out in two interrelated areas: organizational and scientific and technical.



Some aspects of the development of refrigeration automation
摘要
From the distance of the past five decades since the founding of VNIIholodmash, one can see the enormous work done by its team, which is reflected in the evolutionary development of domestic refrigeration engineering.



Development of the scientific and technical base for the creation of refrigeration machines with centrifugal compressors
摘要
The development of the scientific and technical base for the creation of refrigeration machines with refrigeration centrifugal compressors was started by VNIIkholodmash together with Kazankompressormash OJSC from the mid-70s with the assistance of VB Shnepp Research Institute.



New developments in screw and scroll compressors
摘要
Along with the design of refrigeration compressors, employees of the Department of Rotary and Reciprocating Compressors of VNIIholodmash-Holding OJSC, together with OJSC Penzkompressormash, are actively working to modernize air compressor stations with screw compressors. Over the past three years, a number of air screw compressors have been created with a capacity of 4 to 40 m3 / min and an overpressure of discharge of 0.7 ... 0.9 MPa. These compressors use a new profile of the rotor teeth, designed by OAO VNIIholodmash-Holding, taking into account modern trends.



Development and implementation of absorption lithium bromide refrigeration machines and heat pumps
摘要
For more than 40 years, absorption lithium bromide refrigerating machines have been successfully used in world practice to produce chilled water (7 °C). In our country, the introduction of machines of this type was initiated by the work of the Department of Refrigeration Machines of the Leningrad Technological Institute of the Refrigeration Industry (now St. Petersburg State University of Low-Temperature and Food Technologies), where, under the guidance of prof. L.M. Rozenfeld designed a pilot sample of an absorption lithium bromide refrigerating machine with a design capacity of 3 MW. Tests of this sample as a refrigeration machine and heat pump, carried out by LTIHP and VNIIkholodmash in 1964-1966. at the industrial stand of the Chernihiv artificial fiber plant in a wide range of temperatures of heat sources and operating modes laid the foundation for the production of machines of this type in our country.



Cosmic abbreviations of cold
摘要
Chief designer of the project N.I. Ilyina has been working at the institute since its foundation, having gone from a young specialist to the head of a department, which she led for more than 35 years. This charming woman, thanks to her high professional and human qualities, has great authority among numerous customers, system manufacturers, installers and operators. More than 40 different thermostating systems, stationary and mobile, air and liquid, developed under her leadership for space rockets and launch complexes have practically no failures and operate for 20 years or more. And today, N.I. Ilyina is full of innovative ideas, energetic and inspires all the employees of the department with her enthusiasm.

摘要
Compressor-condensing units are designed to work as cold generators as part of refrigeration units with direct cooling systems.



Refrigeration machines of the third millennium
摘要
YORK International is celebrating the third millennium with a new approach to the refrigeration market. The essence of this approach is the maximum satisfaction of customer requirements due, first of all, to a wide range of manufactured equipment, its highest quality, reliability and efficiency. Continuing the production of refrigerating machines that have proven themselves in the market, such as reciprocating YCAJ / YDAJ, YCAM, screw-YS, absorption - YIA.YPC, since 2000 the corporation began manufacturing new products.



YORK International is the first foreign company to start production of central air conditioners in Russia
摘要
At the end of August 2000, YORK International Corporation opened a plant for the production of central air conditioners in Zelenograd (Moscow). At the initial stage, they will be assembled from 100% imported components under the license of the YORK central air conditioner plant in Italy. In the next few years, according to the production development program, a transition to Russian-made components is expected. YORK central air handling units meet the highest quality standards and can be used in any configuration for a wide variety of applications.
A unique computer program allows you to optimally select the main elements that meet specific application conditions at a minimum cost, take into account the special requirements and operating conditions of the installation, as well as obtain all the necessary technical information and certified graphics.



Modern trends in the improvement of water-cooled refrigeration machines (chillers) for air conditioning systems
摘要
The production program of the world's leading manufacturers of water-cooled refrigeration machines (chillers) used in air conditioning systems, as a rule, consists of two groups of equipment: a group of domestic chillers (standard cooling capacity range 5 ... 150 kW) and a group of industrial chillers (range standard cooling capacity 35 ... 1500 kW). The cooling capacity ranges are estimates: depending on the manufacturer, the limit values can either increase or decrease.

The use of CAD in the design of refrigeration units
摘要
The creation of any mechanism or device requires design work to identify the number and type of operations, material costs, etc.
One of the most important stages in the development of the project is the preparation of design documentation for the product. Before the advent of the computer age, this stage took a lot of time and people. As a result, the product often lost its relevance.



Cold gold in South African mines
