The new development of Carrier, which is one of the world leaders in the production of air-conditioning equipment, has a number of undeniable advantages. They include reliability, high performance in terms of energy efficiency, and the opportunity of a flexible approach to design and installation of air-conditioning equipment and cooling systems.
Today people spend more time in closed premises: at home, at work, at school, at the university, at transport or even on vacation. In this regard, should not be underestimate the importance of the air quality inside the building. Previously buildings and facilities were designed with account of the high quality of outdoor air and the significant proportion of natural ventilation. At the moment most skyscrapers have unventilated glass facades, and to achieve a comfortable environment in such buildings they use conditioning and air heating on a large scale; this refers to partial recirculation in order to conserve energy as well. This creates fundamentally new problems that are related to the indoor air quality.
Several hundred units were supplied, mounted and commissioned in Russia since the start of Carrier Aquasnap aircooled chillers manufacturing. Currently they are operated at many commercial, public and industrial objects with success. On a constant basis Carrier company monitors the industry-related market trends and customers’ demands. Researches taken several years and resulted in Aquasnap updated series are based on modernized models of single block chillers.
Traveling more than 500 meters or 100 floors in a continuous elevator trip is challenging and doesn’t really make sense using conventional technology. Therefore KONE has developed a new innovative tripping technology KONE UltraRope™.
Facade Maintenance System (FMS), also known as Building Maintenance Units (BMU) are widely used throughout the world to repair and keep clean the facades of high-rise, medium and low-rise buildings. This is not only convenient, because the FMS allows looking perfect even the most complex configuration buildings, and also rather profitable – these systems pay off in the first years of operation, and they are designed for a lifetime service. Naturally, in such complex objects like are skyscrapers works only high-technology equipment, both during construction and service stages of already occupied building. It’s fast, easy and safe.
Modern metropolises are growing not only horizontally, but also vertically. Buildings are becoming taller and taller, and there is a need to regulate the passenger flow within them. This is one of the main reasons why KONE, which has over 40 thousand employees, focuses its attention on innovative developments for managing passenger flows – People Flow®, which allow people to move easily, comfortably and safely inside highrise buildings – whether it is office centres, hotels or residential complexes.
It is important to understand that a hotel fire alarm and detection system should provide early detection of the source of ignition and at the same time guarantee a nearly complete absence of false alarms – to avoid the financial and reputational losses, not to mention human casualties. This article dwells on the problem of choosing a right fire alarm system, fire detectors and their arrangement based on particular features of a property we want to protect.

Japanese company Toshiba has produced air-conditioning systems for over half a century. In 1977 Toshiba was the first to introduce microprocessor controlled air conditioners, and in 1981 the company produced an inverter air conditioner. In 1998 it launched Japan’s first air conditioner that operated on eco-friendly refrigerant R410A. Innovative technologies make it possible every year to improve the efficiency, comfort and reliability of air conditioning systems. In recent years Toshiba has created the world’s first VRF systems with three-inverter compressors in the outdoor unit.
The fact that VRF systems are a really serious competitors to chiller-fancoil systems is no longer doubtful. In the market of professional climate control equipment the interest towards VRF keeps on growing every year, and today a lot of customers give preference to it. However, most customers do not hurry to completely abandon other equipment in its favor. This is caused by many factors, including the opportunity to work with VRF in combination with supply and exhaust ventilation systems and use them as compressor and condenser blocks.
