A new porous system in power plants allowing the management of crisis heat exchange at boiling water structures has been investigated. This study refers to thermal electrical stations and devices for cutting natural artificial mineral media. Combustion chambers supersonic nozzles were cooled by different structures. The optimum cell sizes determined data on transfer capacity (critical) flow obt...
Cooling systems for the CLEO III detector require proper control and monitoring in order to protect the integrity of the electronics and to maintain mechanical stability (constant temperature control). In our system, all cooling loops are controlled by a single Small Logic Controller (SLC), a programmable off-the-shelf industrial process-control computer. We use LabVIEW (Laboratory Virtual Inst...
If a current pulse with a magnitude several times higher than the steady state optimum current is applied to a thermoelectric cooler, an instantaneously lower temperature than that reachable at the steady state can be obtained. Most previous studies of this transient cooling effect focus on the minimum temperature achievable for free standing thermoelectric (TE) elements. In this work, we syste...
Phase change materials (PCM) are thermal storage materials with a high storage density for small temperature range applications. One such application is the storage of natural cold of the night to use during daytime, called “free cooling”. Very high energy efficiency can be reached as the cold has not to be generated. Those systems are especially interesting for lightweight buildings, which hea...
The excessive temperature fluctuations during dental implant site preparation may affect the process of bone-implant osseointegration. In the presented studies, we aimed to assess the quality of cooling during the use of 3 different dental implant systems (BEGO®, NEO BIOTECH®, and BIOMET 3i®). The swine rib was chosen as a study model. The preparation of dental implant site was performed with t...
