Application of sound quality metrics in automobile air-conditioning unit

An adsorption system driven by solar heat or waste heat can help to eliminate the use of ozone depletion substances, such as chlorofluorocarbons (CFCs) and hydro-chlorofluorocarbons (HCFCs). In recent years, adsorption system has witnessed an increasing interest in many fields due to the fact that this system is quiet, long lasting, cheap to maintain and environmentally benign. Although adsorption system is not commonly used for automobile air conditioning, adsorption-cooled mini-refrigerators have been marketed for recreational transports (motor homes, boats, etc). Hence, there exists a need for a creative design and innovation to allow adsorption technology to be practical for air conditioning in automobile. The objective of this paper is to present a comprehensive review on the past efforts in the field of solar adsorption refrigeration systems and also the feasibility study of this technology for automobile airconditioning purpose. It is a particularly an attractive application for solar energy because of the near coincidence of peak cooling loads with the available of solar power.

Automobile Air Conditioning

Automobile air conditioning systems (ACS) might be considered an extreme environment for many microorganisms. Organisms surviving and proliferating in these systems may be presented with temperature changes ranging from subzero to over 140°F, water activity from saturation to dryness and a nutrient complexity including varying levels of hydrocarbons. Microbial communities develop in ACS and sometimes proliferate to the extent of massive colonization and production of objectionable odors.In a few instances microorganisms emanating from ACS have been associated with hypersensitivity pneumonitis and other allergic reactions. Previously we demonstrated that foam insulation and glues, in particular, on ACS insulations were colonized by fungi such as Aspergillus, Aureobasidium, Cladosporium, and Penicillium. Such fungi often are implicated in colonization of similar substrates in buildings categorized with the sick building syndrome.A total of 42 ACS from the United States, Europe and Central America have been examined by cabin air sampling culture swab, direct microscopy or a combination of these techniques.
