Abstract:

Multiple fans are sometimes used in an array configuration to cool various types of electronic equipment. In addition to adding another noise source, using two fans with closely spaced blade passage frequencies (BPF) can create an annoying beat frequency. A two fan array with each fan having a different BPF was considered. The fans were theoretically modeled at the BPF and first harmonics. Each fan has two acoustic paths to the far field. Thus, each fan was modeled as a two source array. The first control configuration consisted of one control filter using six control sources and six error sen

Abstract:

<p>Nowadays, office buildings often have large temperature variations during the day and building envelope acts as an energy storing mass and damp these effects and so Offices need more cooling because of internal heat sources. But we know that cooling is more expensive than heating and it uses the very good quality of energy sources (exergy). Controlled Active Mass (CAM) is new approach to absorb radiant heating and acts as a passive cooling device. It has direct cooling effect and reduces the peak load. CAM is a new cooling system design with applying the low energy sources and operates at w

Abstract:

[EN] This PhD thesis studies the application of the magnetic refrigeration technology in the air-conditioning system of automobiles. Thermal models of each of the components of such a system have been developed with the purpose of determining accurately its global performance. A dynamic one-dimensional model of a parallel-plate active magnetic regenerator (AMR) has been developed. The model is based in a new numerical scheme that reduces the computation time by 88% compared to the most commonly employed method. The model reproduces very accurately the passive regenerator cases with analytic so

Abstract:

Baigiamajame magistro darbe nagrinėjama problema – dideli energijos poreikiai vėsinimui biurų pastatuose, dėl vis didėjančių mikroklimato kokybės reikalavimų, didesnių šilumos pritekėjimų į patalpas ir šilumos išsiskyrimų dėl naudojamos įrangos. Problemos sprendimui darbe suprojektuotos keturios oro kondicionavimo sistemos su skirtingais šilumnešiais: oru, vandeniu ir freonu. Atsižvelgiant į šilumnešio tipą suprojektuotos ventiliatorinių konvektorių, aktyviųjų šalčio sijų, freoninė ir orinė vėsinimo sistemos.

Abstract:

Les solucions actuals de refrigeració en circuits integrats en 3D (3D-IC) no proporcionen sistemes capaços d'adaptar el seu comportament a condicions variables en el temps i l'espai, fet que comporta un sobre refredament quan la demanda de fred és baixa. Això implica caigudes de pressió addicionals al canal del fluid i per tant, potències de bombeig sobredimensionades per condicions variables. A més, en els treballs existents, la uniformitat de temperatura sobre la superfície del xip només està optimitzada per una distribució de càrrega de calor determinada i no pot adaptar-se a escenaris de c

Initially, eight options had been identified and through a process of determining the degree of commercialisation the alternative options were reduced to three. These options, referred to as the sustainable cooling

La force de Casimir, du nom du physicien qui prédit en 1948 l'existence de cette force attractive dans la configuration idéale de deux miroirs parfaits, plans et parallèles, est d'origine purement quantique. Elle résulte de l'existence des fluctuations quantiques de point zéro du champ électromagnétique et joue un rôle prépondérant dans le fonctionnement des nanosystèmes mécaniques en cours de développement et qui pourraient dans les années futures révolutionner l'industrie de la microélectronique. Pourtant, les effets correctifs liés à la conductivité des surfaces ou à l'empilement diélectriq
