ELECTROFIN comparison - protective coating against corrosion

Our solution to stop corrosion, even in high risk conditions

/in /by

One of the aspects that should be always taken into consideration in HVAC industry is prevention of damages and deterioration of components.
In particular, corrosion often affects heat exchangers and can lead to performance loss and failure.

To avoid or delay corrosion and its effects, in addition to standard coatings, we can provide a special coating solution for all applications and environmental conditions with very high risk of corrosion.

This special coating is ELECTROFIN, a factory-applied electro-deposition coating process that guarantees complete heat exchanger coverage. The coil is immersed in a bath. Here the coil acts as a magnet and attracts the coating to every surface. The result is a thin, flexible, durable, corrosion-resistant coating.
Main feature of this special coating is that, whereas other coating processes fail in covering the entire surface, especially in particular structures such as microchannel or round tube plate coils, ELECTROFIN coating penetrates deep into the 100% of coil surfaces, covering all edges and filling all cracks.

2016 hottest year

2016 to be the hottest year on record

/in /by

2015 was recorded as the hottest year but 2016 is going to surpass it.

WMO (World Meteorological Organization) has published the provisional statement for 2016 to inform United Nations Climate Change conference taking place in Morocco on the occasion of COP22.

These data, updated to September, show that global temperatures in 2016 are around 1.2 °C above pre-industrial levels. Preliminary data for October indicate a sufficiently high level for 2016 to be the hottest year on record. This means that 16 of the 17 hottest years on record have been this century.

Other climate-change indicators are record breaking. Levels of greenhouse gases in the atmosphere are still increasing; arctic sea ice levels on the contrary are very low; major heatwaves and flooding are becoming regular.

“Temperatures were above the 1961-90 average over the vast majority of land areas” WMO statement reports. “Temperatures were above normal over most ocean areas. […]Coral mortality of up to 50% was reported in parts of the Great Barrier Reef. […]Global sea levels rose about 15 millimetres between November 2014 and February 2016 as a result of El Niño, well above the post-1993 trend of 3 to 3.5 mm per year”.

Also greenhouse gas levels increased: “Annual average global carbon dioxide concentrations in 2015 reached 400 parts per million (ppm) for the first time. Initial observations indicate new records in 2016”.

In this scenario, WMO underlines the importance and urgency of putting the Paris Agreement into action. The Paris Agreement came into force in record time, if compared with other climate agreements, but the most important thing now is not to stop. “WMO is working to improve monitoring of greenhouse gas emissions to help countries to reduce them” says WMO Secretary-General Petteri Taalas.

COP22 started with Paris Agreement entered into force

/in /by

On November 4, less than 1 year after COP21 and a couple of days before COP22, the Paris Agreement entered into force. It was ratified on October 5, when the threshold for entry into force was fully achieved.

The Paris Agreement has as main objectives the reduction of greenhouse gases emission and the reduction of global warming below 1.5 °C compared to pre-industrial levels (1880-1899).

In order to reach these goals 195 Parties committed to take action from both industrial and economical point of view. The shift to a low-carbon economy is seen by the IPCC as the most effective way to reduce global warming.

COP22, held in Marrakech, November 7 to 18, will focus on action items in order to achieve the priorities of the Paris Agreement, especially related to adaptation, transparency, technology transfer, mitigation, capacity building and loss and damages

What is expected from COP22?

If COP21 led to the signature of what many experts define as an historic agreement – “the Paris Agreement is an instance of extraordinary participation between independent parties. Achieving such a degree of multilateralism is difficult, especially on complex, contentious issues like climate change” – COP22 should be expected to lead to the implementation of the Paris Agreement and additional commitments to climate action from the private sector.

Here are two interesting article about the importance and legacy of Paris Agreement and about what we should expect from COP22:

2017 AHR EXPO

Geoclima for the first time in the US!

/in /by

The time has come to go overseas and land in Las Vegas next January for the 2017 AHR EXPO.

From January 30 to February 1 Geoclima and Clima Tech will exhibit at the AHR EXPO, the International Air-Conditioning, Heating, Refrigerating Exposition, which is one of the most important world HVACR event of the year and is held in major cities across the US. The show will host more than 2000 exhibitors and attract crowds of 60000 industry professionals from every state in America and 150 countries worldwide.

We will be there, introducing our products and technology to the US market.

Come and find us at North Hall – Booth N11514!

Geoclima provides and tests both cooling and heating

/in /by

For a special project, Geoclima designed and developed reversible heat pumps to provide both cooling and heating. In particular, the project concerned the design of 4 air cooled reversible heat pumps with four scroll compressors each.

We always test every single unit and also in this case all units have been tested in the presence of the client, who asked for a witness test we can always offer on request.

Thanks to the climate chamber of our test center we have been able to simulate actual environmental conditions of the site of installation.

In this particular case, with units providing both cooling and heating, we had to simulate both summer conditions, with ambient temperature up to 35 °C, and winter conditions, with ambient temperature down to -4 °C.

In summer mode, reversible heat pumps are designed to provide 460 kW cooling capacity each. In winter mode, they are designed to provide 372.8 kW heating capacity.

Each unit has been tested, one by one, according to Eurovent regulations, and ambient temperature have been simulated. Units have been tested at full load and at part load 25%, 50% and 75%.

The major difficulty was related to winter mode and to reach negative temperatures when actual ambient temperature outside climate chamber was around 13 °C. But in both cases, summer and winter mode, the desired temperatures have been reached and also exceeded.

Design conditions have been satisfied and in particular in winter mode, heat pumps provided even more heating capacity than required.

In addition to this, client required also to carry out a noise test on units. Design data provide maximum 71 dB(A) – 5m: this condition was tested and satisfied in the presence of both client and a certification agency.

All air and water probes, transducers, flow meters and tension meters are tested once a year by ACCREDIA, the Italian National Accreditation Body, and are calibrated according to AHRI standards.
