Multiple-split air conditioning (MSAC) system has become an attractive form of air-conditioning system for smallsized commercial and residential buildings. For a common room air conditioner, the only factor affecting the performance under a fixed outdoor and indoor condition is load rate of the indoor unit. But for the MSAC system, the indoor units will have quite different working situations u...

Nanoporous alumina sheets can inhibit the growth of frost layer in a low-temperature environment, which has been widely used air-conditioning heat exchangers. In this study, nanoporous with pore diameters 30 nm, 100 200 300 and 400 nm were prepared by using anodic oxidation method conventional polished aluminum sheet as reference. A comprehensive in-depth analysis frosting mechanism proposed ba...

Abstract This article applies multiple nonlinear regression methods to establish a forecasting model for the load characteristics of air conditioning in shopping malls at different times. Based on Python data, determine functional relationship refrigerant parameters concerning pressure and temperature. The uses kernel smoothing estimation technology calculate room temperature probability densit...

OBJECTIVE To create a mechanical model that could be regulated to simulate the conditioning of inspired and expired air with the same normal values of temperature, pressure, and relative humidity as those of the respiratory system of a healthy young man on mechanical ventilation. METHODS Using several types of materials, a mechanical device was built and regulated using normal values of vital...

Ground thermal energy as a clean and sustainable energy source has received significant attention lately. Several strategies and hybrid configurations have been proposed to harvest geothermal energy for air conditioning and industrial purposes. The possibility of moist soil freezing in the vicinity of borehole tubes is known to be the source of several benefits and difficulties. The high storag...

The cross-coupling reaction between phenylboronic acid and various types of aryl halides (Suzuki reaction) was carried out using a catalytic amount of a new palladium catalyst (1-benzyl-3-(1-benzyl-1-methylpyrrolidin-1-ium-2-yl) pyridin-1-ium palladium chloride [DBNT][PdCl4]) in poly (ethylene glycol) (PEG-200) in the presence of KOH as the base. This new catalyst was synthesized and...

Access to housing in low-income sectors brings up the need for a relevant reflection on Latin America. In this context, wood-based Modular Housing Solution (MHS) has been developed neighborhood outskirts of CABA called La Plata, oriented improvement working-class sectors, and managed by labor cooperative, university, scientific-technical sector. The objective is evaluate thermal light behavior ...

In this project we provide a survey of research aiming to develop the next generation of intelligent sensor networks – decentralised, self configuring and self managing – such networks represent the future of ubiquitous and pervasive computing. Sensors that seamlessly integrate with their environment – and act “intelligently” without the need for a central point of control will revolutionise th...
