Dishwasher Tarnish Aluminum

photovoltaic




Background



For several years, we build for our major customers in the existing cellular offices to large offices. New 31Personen must share a 350m2 space.


was in order to make the summer more pleasant to work decided to cool each floor by means of its own monobloc. No sooner were already built the first complaints. "I feel too cold ... leeches with me ... the air is too loud. "





parallel We were in the planning of a new building was equipped only with surgeries. We were with the search for alternatives to air cooling. We have taken the system building component or cooling ceiling into consideration. In this learning journal I would analyze the functioning of the cooling blankets and building component.







building component

concrete core or building component is marketed as a technology of the day.

The cooling is achieved by means of storage capacity of the concrete ceiling. The Mass of the concrete slab is cooled at night. The ceiling thus serves as a storage and day out gently at peak space heating. Of course you can use the same system in winter space heating. The blanket serves as a giant heat lamps. In order to warm heat lamps that meet the already low flow temperatures. This has a positive effect on the heating costs and also this system can be operated with heat pump or solar panels.

as the main component of the system are plastic tubes that are placed by spacers in the mold. Then flows through these tubes, the hot or cold water.

A big disadvantage of this system is, ironically, the inertia of the concrete. It is precisely because the concrete is so slow, you can not respond flexibly to changes in temperature. This results in the transition periods often lead to disgruntled users.

we all understand a building, which was carried out by building component, the Sunrise Tower in Oerlikon.

chilled

As mentioned above, the great disadvantage of the building component the inertia of the storage medium. This flexibility is provided by the system cooling blanket.

advertise The producers of the cooling ceiling with the similar advantages as the above.

The cooling blanket cool noise. Because it works by means of radiation cooling, the system is perceived by the people pleasant. There are no Zugserscheinungen.

A possible medium for cooling ceilings are copper tubes. Because in a commercial environment are embedded into a suspended ceiling is, this system can be easily installed between concrete floor and suspended ceiling. Of course, this system is also reversible and can be converted in the winter as surface heating. This is particularly interesting in combination with reversible heat pumps, which can be switched to cooling mode in summer.

The systems consist of a cooling coil of copper tubing from heat conducting strips, a ceiling element, flexible hoses and connecting lines and fittings from diffusion-tight plastic tube.

The cooling coil will be placed in the metal or plaster ceiling panels and through Screw fixed.

Conclusion


In the above construction we have chosen for the cooling ceiling solutions in combination with a conventional cooling system. A major argument in favor of the chilled ceiling is that you get to the cooling blanket in case of damage at any time. The building component however, one would have to paint tips onto the concrete. Next was the short response time of the cooling ceiling is a great advantage.

are now the target's office for almost a year in operation. In ordinary everyday life, the cooling ceiling systems and cooling systems work very well. At very high outside temperatures, we had to constantly receive complaints of customers, it was too warm.

The investigation found out the Santia that people in the office each had warm and consequently opened the window. Now streamed out warm air, this in turn means that the flow temperature below the cooling ceiling The dew point fell and ceased to operate. This is done so that no condensate gets on the plaster ceiling. Since we have now removed the window handles, all parties are happy.

is one of my findings from this that you can not please everyone, if 90% are satisfied, must be content with that.
