Each year energy saving becomes more relevant. The limited nature of energy resources, their high cost calls for minimization of expenses due to implementation of new technologies.

A reduction in thermal and power energy consumptions allows a considerable reduction in costs of purchasing of resources. Energy savings in construction also help improve the ecological situation worldwide. Enterprises consume huge amounts of energy and at the same time emit part of non-utilized energy from technological processes to the environment. Energy saving technologies in construction due to utilization of this discharged energy are already there. These are utilizing boilers generating steam or hot water, thermal pumps utilizing waste water temperature, liquidating cooling towers and similar energy saving technologies in construction.

Costs of implementing these technologies are paid back sufficiently soon. There are also other methods of energy saving in construction, such as transfer of part of energy consumption to nighttime.

The company EUROVENT GC cooperates with world producers of equipment allowing minimization of energy consumption costs.

First, this is a Sweden company SWEGON AB (PM-LUFT AB prior to 2005), one of the leaders among producers of energy saving ventilation equipment. The EUROVENT-certified efficiency factor of heat utilization of ventilation units AB reaches 85% with equal consumptions of incoming and outgoing air, Such efficiency allows a reduction in heater capacity 7-8 times compared to traditional systems and therewith a reduction in total energy intensity of an object both at the design stage and during operation. With the existing prices of energy carriers the payback periods of investments in this equipment in Russia are 3-5 years.

Units SWEGON of GOLD series are mass-produced complete air preparation units for comfortable ventilation produced in several standard types for air consumptions up to 9.5 m3/s (34,000 m3/h).

The units are equipped with efficient fans meeting the growing requirements to energy efficiency and having an inbuilt automation system IQnomic with a great number of readily-activated functions including communication.

GOLD installations of the following types are produced:

- RX, rotor heat recovery unit,

- PX, laminated heat recovery unit,

- CX, battery heat recovery unit,

- SD, air supply unit or exhaust unit,

- LP, rotor heat recovery unit.

In addition to ventilation units we widely use chilled beams and cooling coils. Chilled beams ventilate, cool, and heat air. Air is supplied to 4 different directions. A short turbulent jet ensures efficient mixing of air, creating an excellent microclimate both in the cooling and heating mode. Air consumption and its distribution pattern can be changed many times, in each direction.

Even when the function of a room is changed, upon alterations and such, it is sufficient to adjust your system to new conditions, and you have maximum comfort without additional expenses.

Presently specialists of our company master energy efficient innovative refrigeration sets Qantum.

The heart of a Qantum is a centrifugal turbo compressor with regulated revolutions. The drive shaft is installed on supporters in which the magnetic bearing technology without lubrication is used. The result is the absence of mechanical wear of revolving parts and minimal risk of failures. Besides, an integrated technology ensures also low starting current and automatic adaptation of power to the current cold demand.

Due to these factors the refrigeration set Qantum is distinguished with high efficiency of energy use, especially in the range of partial loads, which results in a reduction of required cooling efficiency.

Special attention in energy saving is given by EUROVENT GC to the equipment manufactured by the French company CIAT, a cold accumulator CRISTOPIA

CIAT’s subsidiary company Cristopia Energy Systems has developed a unique technology: cold accumulators.

This technology was developed in 1982 specially for air conditioning systems and cooling systems of trading and industrial enterprises. It allows accumulation of energy in non-peak load hours (periods of the minimal energy tariff) and use of it in peak hours. This ensures reduced loads on power networks and also a considerable reduction in operation costs.

Most traditional air conditioning and refrigeration systems are designed for maximum loads, even if such load is within short periods only. Moreover, the peak load on refrigeration systems acts only several days a year, and also considerably varies within a day.

Cold accumulators make it possible to control peak loads. Energy is accumulated in non-peak hours and used when the cooling demand exceeds cooling capacity of the installed refrigeration machinery.

This technology not only ensures considerable economy of money but also significantly reduces negative impact on the environment:

  • CO2 emissions are reduced

  • energy consumption in peak hours is reduced

  • energy consumption is reduced (savings up to 15 %)

Sphere of application:

Air conditioning in public buildings: trade centers, supermarkets, airports, cinemas, etc.

Refrigeration machinery: pharmaceutical industry, ice rinks etc.

Service systems: telephone stations, chemical production, explosive storages, research laboratories etc.

One should note that apart from reasonably selected energy saving equipment, of no little significant factor is a systemic approach and a properly designed system of operational control of all the interlinked engineering equipment, i.e. ventilation, conditioning, heating, which allows energy consumption to be reduced though balanced, coordinated operation of expensive machinery.
