In The Netherlands is it possible to heat water with a computer. Well, let’s better explain it, heating water using the waste heat from servers. We’ve talked about it already in a previous article a few weeks ago, and we are pleased to go more in depth in this interesting project: the innovative idea comes from the start up Nerdalize, and consists in the recovery of the waste heat produced by a distributed network of servers, installed at homes, employed to produce hot tap water. Servers in traditional datacenters consume a lot of energy and produce a lot of waste heat, requiring the 40% of the electricity consumed for server’s cooling.
The Nerdalize solution optimizes in a smart way the energy consumption, and the company built its own heating device that integrates the computer servers in it, able to manage the heat exchange from the servers to hot water. The system is called CloudBox and comes with a boiler tank, and is an add-on easy to install in existing central heating systems. Installation is handled by the company, which also pays the energy used by the servers.
This kind of shell and tube heat exchangers for the pharma sector have special full stainless steel execution, meeting the hygienic requirements of the sector and to prevent possible corrosion in contact with aggressive substances.
1. Check safety and control devices: for correct installation and functioning, be sure that the range settings are proper for the operation. Manually activate and test the instruments and apply all tests necessary to assure the right functioning.
2. Check for leakage.
3. Remove moisture from the system, using dry compressed air or other suitable means.
4. Fill the system with heat transfer fluid.
Fill the system with heat transfer fluid, with all vents to the expansion tank or atmosphere open for air removal. Fill the expansion tank to low level. Where needed (in low temperature environment), have the steam tracing system switched on.
Open all valves, then start the main circulating pump in accordance with the manufacturer’s recommendations. Observe the liquid level in the expansion tank, refilling as necessary until the system has been filled. The expansion tank should be adjusted to 70%–75% full when the hot operating temperature is reached.
Suggested start-up procedure for new systems circulate the heat transfer fluid through the system for about 4 hours to eliminate air pockets and to assure complete system fill. Before firing the heater, be sure that the heat transfer fluid is circulating freely through the entire system.
5. Start the heater. Bring the system up to temperature very slowly—about 35°C per hour. This should prevent thermal shock to heater tubes, tube/heater joints, refractory materials, etc., and will allow operators to check the functioning of instruments and controls. The slow heat-up also will allow moisture trapped in all sections of the system to escape as a vapor.Hold the temperature above 100°C until no signs of moisture remain (e.g., knocking or rattling of pipes, moisture from vents, etc.).
This year, in Tempco we want to wish you a warm Merry Christmas in an even smarter way…
An interesting tip related to heat recovery and datacenters comes indeed from Nerdalize, a Netherlands based company. The idea is to combine the growing demand of computing power with the heating need in homes, leveraging on a delocalized network of cloud servers in homes.
The solution could be an alternative to traditional big datacenters, huge energy wasters that employ 40% of its total energy consumption on cooling and dissipating the heat produced by servers.
Cloud servers at homes would then represent a sustainable computing power source and an immediate source of heating power, decreasing at once both energy consumption aimed at datacenters’ cooling and households’ energy bills, thanks to heat recovery from servers directly in homes.
And with that in mind, the Tempco team would like to wish you a very Warm and Merry Christmas, and our most sincere wishes for a Happy New Year 2018!
Thermoregulating units, updated Technical sheet for the Tempco TREG HC ST series. The thermoregulation control units by Tempco produce water at controlled temperature, in an operating range between +10 and +120°C (the range may be extended on request), with +/-1°C tolerance.
The units employ as fluids steam for the heating cycle and chilled water for cooling. Other types of fluids may also be used, following an assessment by Tempco technical department on the compatibility with the units’ components.
A customer in the pharmaceutical industry placed an order for thremoregulating units intended for a new plant for the production of anesthetics. The unit is actually in the start-up phase, and works directly on the product, regulating the temperatures required in the several steps of the production of active ingredients employed in the anesthetics.
At first glance it sounds like a contradiction, but this is the effect actually achieved by the innovative coatingSolcold developed by an Israel-based startup.
The cooling coating employs an active cooling process involving the basic principles of laser cooling, applying the idea to the spectrum of sunlight. The coating not only reflect the sunlight, lowering the temperature of exposed surfaces and rooftops, decreasing energy consumption of conditioning systems. The solution employs the sun rays to activate a chemical process able to transform façades and rooftops in a sort of layer of ice, actively cooling them up to 10° C.
Among the several offers for scholarships launched by Italian Universities, often aiming to digitalization and Industry 4.0 technologies, recently our attention has been caught by an opportunity provided by the University of Naples Federico II, for a scholarship in the ‘Development of dynamic simulation models for cogeneration plants’.
Is great to see that R&D is going on in the CHP sector, which in Italy is still having large opportunities to increase energy efficiency, with applications in the industry but also for medium-small utilities, such as SME and residential sites thanks to micro-cogeneration and microgrids.
TEMPCO researches and develops systems and solutions for cooling, heating, control temperature and heat exchange in different industrial processes.
