Research on Insulation Characteristics of Distributed Winding with Cooling Chamber for Evaporative Cooling Transformer

Die moderne Samenbank lässt sich mit Medienbegriffen beschreiben, von Bestand bis Infrastruktur. Stets bleibt als blinder Fleck die Medialität des Samens, dessen Vitalität im Dunkel der Kühlkammer künstlich verlängert wird. Der Beitrag diskutiert Varianten, das Problem der Teleologie der Natur in Medienbegriffen abzuhandeln und bietet eine neue Geschichte von ›den Bienen und den Blumen‹. Er hebt den Samen als Inbegriff einer nicht reduzierbaren Substanz hervor, dessen Latenz als mediales Apriori des Lebenden begreifbar wird. A modern sperm bank can actually be described by using media terms such as ›stock‹ or ›infrastructure‹. However, the mediality of sperm seems to be persistently lingering in a blind spot, its vitality artificially prolonged in the dark of the cooling chamber. This article discusses different variants to treat the problem of describing the teleology of nature with the help of media terms and offers a new take on the story of ›the birds and the bees‹. The argumentation stresses the importance of sperm as the very quintessence of a non-reducible substance whose latency as a medial a priori of life thus becomes palpable

System Configurations

This study provides comprehensive details of evaporative cooling options for building air-conditioning (AC) in Multan (Pakistan). Standalone evaporative cooling and standalone vapor compression AC (VCAC) systems are commonly used in Pakistan. Therefore, seven AC system configurations comprising of direct evaporative cooling (DEC), indirect evaporative cooling (IEC), VCAC, and their possible combinations, are explored for the climatic conditions of Multan. The study aims to explore the optimum AC system configuration for the building AC from the viewpoints of cooling capacity, system performance, energy consumption, and CO2 emissions. A simulation model was designed in DesignBuilder and simulated using EnergyPlus in order to optimize the applicability of the proposed systems. The standalone VCAC and hybrid IEC-VCAC & IEC-DEC-VCAC system configurations could achieve the desired human thermal comfort. The standalone DEC resulted in a maximum COP of 4.5, whereas, it was 2.1 in case of the hybrid IEC-DEC-VCAC system. The hybrid IEC-DEC-VCAC system achieved maximum temperature gradient (21 °C) and relatively less CO2 emissions as compared to standalone VCAC. In addition, it provided maximum cooling capacity (184 kW for work input of 100 kW), which is 85% higher than the standalone DEC system. Furthermore, it achieved neutral to slightly cool human thermal comfort i.e., 0 to −1 predicted mean vote and 30% of predicted percentage dissatisfied. Thus, the study concludes the hybrid IEC-DEC-VCAC as an optimum configuration for building AC in Multan.
