A conditioning dehumidifier system is a simple technology to improve air quality and also reduces air conditioning costs. This experimental study evaluated the performance of a liquid desiccant system by adding copper oxide nanoparticles (NPs). The effect of operating parameters, such as inlet air humidity ratio and desiccant flow rate on air dehumidification rate, was also investigated. The.

In the past, several natural working fluids were used in refrigeration and air-conditioning systems. However, the appearance of CFCs caused a drastic reduction in the utilisation of those fluids. Understanding of the environmental damage of CFCs focused attention on alternative refrigerants. From these, the ones that have minimum (or nil) environmental impact are natural ones. This paper.
An air conditioner (AC or air-con) is an appliance or mechanism designed to extract heat from an area using a refrigeration cycle. In construction, a complete system of heating, ventilation and.
This paper makes qualitative analyses of solar air conditioning systems, demonstrates the feasibility and elaborates on the advantages of solar air conditioning development from the perspectives of environmental protection and energy conservation for the purpose of providing a theoretical basis for the future implementation of the solar air conditioning industry.
It used the descriptive method of research to assess the status of the refrigeration and air conditioning technology of the Cebu Technological University System. It was found out that only seven percent of the faculty obtained Doctoral Degree and the nine percent were Master’s Degree holders. Moreover, data revealed that there was a dearth in technical trainings in relation to technological.
Research on Subway Air-Conditioning System Design. In this paper the research object is the velocity and temperature change of the airflow inside the subway, and the research method is computer simulation. We study the performance and temperature change of the airflow using UG and CFD, compare and analyze the variation of the airflow in the same cross section of different models. Through.
In this paper, an overview of the possible DSM applications in the field of air conditioning and heat pumps is provided. In particular, the focus is on the heat pump sector. Three case studies are analyzed in order to assess the energy flexibility provided by DSM technologies classified as energy efficient devices, energy storage systems, and demand response programs. The load shifting.
T.C. Welch, in Refrigeration, Air Conditioning and Heat Pumps (Fifth Edition), 2016. 25.1 Introduction. Refrigeration technology concerns the movement of heat energy from a lower to higher temperature level. Increasingly, familiar and sometimes less familiar techniques are being applied that utilise the high temperature heat for various purposes, mainly space and water heating. The term heat.
