TECHNOBLOCK - 10 years in Russia

Kenda M.

Abstract

2004 marks the 10th anniversary of the presence of the Italian company TECHNOBLOCK on the Russian market. Is it a lot or a little? In our opinion, this depends on the tasks that the company set for itself and the conditions in which it worked. Taking into account the difficult economic situation in Russia, which is constantly aggravated by defaults (or crises close to them), as well as strong competition, 10 years is not bad. But for a company that has come to Russia forever and sets itself the goal of deep integration into the national economy, 10 years is not much. Today, one thing is clear: TECHNOBLOCK has established itself in Russia, is successfully operating and developing dynamically. The main burden of organizing effective work in Russia, including technical support for engineering projects, fell on the Moscow office of the company, which for all these years has been permanently headed by Mr. Milko Kenda

Climatic test chamber KK-40I manufactured by Frigodesign

Velyukhanov V.I.

Abstract

One of the activities of the Frigodesign company is the design and manufacture of non-standard refrigeration equipment. Climate test chambers are one of the most difficult areas of activity from an engineering point of view, since the cold supply and heating systems, ventilation and air conditioning designed for the chamber, connected by a common control and registration system information, should promptly and accurately ensure the temperature and humidity conditions inside the chamber necessary for periodic testing of commercial equipment. The KK-40I climate test chamber manufactured by Frigodesign, after installation at the customer’s site, was certified by representatives of the State Standard for conducting climatic tests in accordance with GOST 238330-95.

AlfaNova - revolutionary technology from Alfa Laval

Abstract

Alfa Laval's history of leadership in the production of brazed plate heat exchangers dates back to the 1970s. Then a completely new solution was offered to the refrigeration market - a copper-brazed plate heat exchanger for liquid cooling systems. Such advantages of this type of equipment as compactness and strength, high heat transfer coefficient, ease of installation, received a deservedly high appraisal of both manufacturers and consumers of refrigeration equipment. Alfa Laval now offers the world's first AlfaNova heat exchanger made entirely of stainless steel.

Practical application of water chillers

Abstract

Recently, the food industry cannot be imagined without air conditioning units, cooling and freezing of semi-finished products and final products. Not a single modern enterprise can do without refrigeration equipment. In addition, enterprises with technological equipment that generates heat during operation (for example, machines for the production of plastic containers) need cold. Most refrigeration units are designed to cool water and other liquids with a lower freezing point. Examples of the use of water-cooling equipment can be listed endlessly: this is the cooling of milk, beer, wine and other alcoholic and non-alcoholic drinks, candy mass on cooling tables, poultry carcasses, ham, sausages after heat treatment and, of course, air conditioning in rooms. There are many varieties and modifications of water-cooling units depending on their purpose and cooling capacity, installation location, operating mode, cooling scheme. Of great importance are the type of cooled liquid (food or technical), its required final temperature, temperature difference before and after cooling. This article briefly discusses the most common cooling schemes and their respective plant modifications.

Improving the safety of ammonia refrigeration plants

Ovcharenko V.S., Athos V.P.

Abstract

On April 25, 2004, the rarest accident in the operation of ammonia refrigeration plants occurred at the Moscow Cold Storage Plant No. 14 - an ammonia explosion. Ammonia is explosive only in a very narrow range of concentrations in air - from 15 to 28%. Therefore, over the entire long history of the use of ammonia refrigeration machines in world practice, only a few cases of explosions have been recorded. The cause of the last accident was unacceptable wear of equipment, non-compliance by maintenance personnel with elementary rules for the safe operation of ammonia refrigeration systems, and the imperfection of the “Safety Rules for Ammonia Refrigeration Units” ПБ09-595- 03. This accident received a wide response in the press, and, what is most dangerous, it can lead to a ban on the use of ammonia refrigeration units and a massive transition to freons.
