Small engine, large energy save

I’m speaking about cogeneration, which involve a wide range of fields.

New generation engines with more efficient heat exchangers, achieves large energy recovery also with small installed power.

Shell and tube on exhaust, plate heat exchangers on jacket water, give to engineers new target on pay-back investment in the cogeneration plant future.

Covrad, Basco, Bowman heat exchangers manufatcurer, are focused to get maximum performance…Tempco getting feedback from installed units, studied a new pipe design, in order to maximize the recovery on heat exchanger, getting the best on exhaust heat exchanger recuperators.

Sparkling wishes

This year we want to change the way of our wishes…

Today start a new project coming from the idea of Tempco to mash its expertise in temperature’s management in a wide range of production processes along with the oldest tradition in brewing…a new italian craft beer.

YourBeer Tempco

Your Beer 4Xmas is a 1.0 version of the Your Beer project, a special seasonal beer intended for this Xmas 2013 and to start in a sparkling and special way the New Year 2014: a beer mixing three different kind of malts, enriched with the perfumes of bitter orange peel and coriander, to obtain a unique and unmistakable fruity fragrance.

In this blog in the following months you will find news about brewing, stories about beer history and production, but also updates from Your Beer project…
We are planning lots of surprises and new projects, new tastes and emotions… also thanks to your own contribution!

Merry Xmas 2013 and Happy New 2014 to you all!

Sparkling and Happy Moments from Your Beer!

Beer production and thermal energy

It is really cold these days, a taste of the coming winter that reminds us of the coming Christmas.

Yet the thought of a nice cold beer, served in a glass with a lot of condensation and froth, always puts me in a good mood.

While I imagine the aroma of a good Christmas Saison, I wonder about the production processes that hide behind the amber colour of this drink.

Yes… because for insiders these are all well-known facts but for those who drink beer without asking too many questions, this information is not commonplace.

Magnetic nanoparticles could aid heat dissipation

I’m following nanotechnologies world from some years. This science amaze me every time with unexpected discovery.

Last news I fond on the web, is very closed to Tempco field of work, the heat exchange.

Following this link, you can read an interesting technical story:

MIT make a

MIT experiment with magnetite nanoparticles dissolved in water for cooling systems, where the use of magnets increases by 300% the heat exchange coefficient of the nanofluid, which otherwise behaves like normal water.

The system would be more economical for the construction of particular geometries in exchange surfaces (fins and grooves), and could be applied to localized cooling, for example in electronic components …

Data center cooling can save energy

Only a few years ago, data centres were synonymous with major HVAC plant installation, needed to keep computer rooms at low and controlled temperatures.

Even today it is necessary to  dissipate the heat generated by hundreds or thousands of computers working tirelessly in a data centre … every time I enter the room where our small LAN server is housed, even with the heating turned off, even in winter, the air conditioning system is turned on.

The great leap forward made in recent years, is linked to  working temperatures  currently endured by these computers.

Let me explain. Initially, to provide air conditioning to a computer room, cooling systems that provided chilled water at the classic temperature of 7°C, with a temperature difference of 5°C (the classic 7/12°C) had to be installed

Current systems require water for direct cooling at considerably higher temperatures around 15/20°C and, as such, they are more efficient, needing to dissipate less thermal energy.

If thermal energy savings are easily understood, 100 KW is less than 120 KW, it is however more complex to understand and, for technicians, it is linked to the temperature.

In my ebook “Energia termica e processi industriali” (at the moment only in italian language) i explain:

chiller capacity increase and energy consumption decrease, if they produce chilled water at higher temperature, 15°C instead of 7°C.

This is surely a very important aspect in managing data centres. This upward shift in temperature allows you to make assessments involving choices that are definitely more green and less energy intensive.

As demonstrated by the choices made ​​for the latest data centre installations, these complexes tend to be built in areas that provide “water at naturally low temperatures”, fjords, rivers in cold areas, icy seas, mines or the like, or in areas with harsh climates,  so that so-called free cooling can be exploited.

It is precisely these applications which are becoming the key to saving energy for data centres.

 

Free cooling plant to cool down big data center

Plate heat exchangers TPLATEfree coolers TFIN are the products that we have studied and are improving to meet these new and more interesting applications.

 Immersion heat exchangers TCOIL represent the new frontier in free cooling driven by data centres.

A heat exchange system, which combines management costs reduced to a minimum, high quality with unparalleled constructive flexibility. All this combined with the zero cost for main pumping.

note:

1. In essence, with the downward variance of the water temperature required, a cooling system sees its thermal efficiency reduce. Or, we can say that a cooling system that needs to dissipate a defined quantity of thermal energy, at a higher temperature, consumes less than another system that needs to dissipate the same amount of thermal energy but at a lower temperature.

For example: 100,000 Kcal/h of water at 5°C costs more than 100,000 Kcal/h at 15°C.

 

2. A cooling system yields more under conditions of low environmental temperature (within certain limits), compared to an installation in a warmer environment.
