HVAC energy demand is rising: how to deal with it

The necessity of moving towards a sustainable approach to refrigeration is emerging ever more clearly.

Data provided by the researchers during the XVI “European Conference on technological innovations in refrigeration and in air conditioning”, held in June, 27th and 28th, at the Polytechnic University of Milan, reveal that refrigeration equipment accounts for the 40% of building energy consumption and for the 17% of global energy consumption. This 17% is produced mainly by the so-called “industrialized countries”, with North America prevailing, whereas the least developed countries bring up the rear. But the ever-increasing demand for HVAC solutions, coming from the “emerging” countries, will lead to an increase in energy demand and, therefore, energy consumption.

In such a scenario, one has to face four main problems, that are the shortage of energy resources, the need to abandon fossil fuels, the cost of energy supply, climate change. These are all important issues that cannot be underestimated.

Bearing all this in mind, HVAC sector is asked to develop alternative solutions that can reduce energy consumption. To do this, there are two key aspects that must be kept into consideration: refrigerants and technology. Since the Montreal Protocol and the more recent European F-Gas Regulation, many steps have been taken towards the abandon of greenhouse gases in favour of gases with low GWP, such as HFO1234ze and R290. But refrigerants alone are not enough if they are not combined with innovative energy efficient technologies. Therefore, manufacturer of HVAC equipment must develop new solutions that require low running current or that could exploit alternative resources, thus reducing energy consumption.

We expect and are already seeing HVAC market moving toward much more sustainable solutions, but there is still much to do. The design of sustainable and energy efficient HVAC solutions is essential to deal with the ever-increasing development of this sector in the “emerging” countries and to face the growing demand for energy supply.

Turbomiser air cooled chillers with silencers

Turbomiser in the heart of London

A very special project was developed by Geoclima, together with partner Cool-Therm, for two brand-new exclusive buildings in the City of Westminster. The buildings are very high end residential apartments with £1m value each and will be located on different sides of the road. The building construction has begun and project completion is expected for late 2016.

For this project, Geoclima designed and developed two 900 kW air cooled Turbomiser chillers, providing 1.8 MW of total cooling capacity. The chillers are equipped with silencers installed on the top of the fans, so as to reduce noise emissions and to meet the client’s specific acoustic requirements. In addition to that, we also designed an extra lower framework to allow pipework to be installed in the base of the chillers.

The chillers are designed to provide cooling capacity for both buildings and the cooling infrastructures are linked together.

The project was very challenging as it required the customization of the plant not only in terms of performance but also in terms of structural issues.

The two Turbomiser air cooled chillers with silencers have just been installed on the roof the building but are meant to be commissioned in early 2016.



Geoclima at Bangkok RHVAC 2015 for HVAC Thai market

Geoclima introduced itself at Bangkok RHVAC 2015

Geoclima Asia took part in the 10th Bangkok RHVAC, which was held in Bangkok from the 13th to the 16th of August 2015. The exhibition in Bangkok was a great opportunity for Geoclima Asia to introduce its products to the HVAC Thai market.

During the three-day show about 200 visitors came and visit our booth to learn more about Geoclima. Great attention was gathered not only by our products, and mainly by our energy efficiency Turbomiser chillers, but also by the services with provide together with our units, such as our remote monitoring and cloud service Onboard Touch.

The exhibition was a good opportunity to lay the foundation for the activity of Geoclima Asia in Thailand.
