Recovery rates as a tool for goal-oriented treatment of cooling appliances?

چکیده
The treatment of cooling appliances in Austria is mainly influenced by two factors. On the one hand is the changing composition of cooling appliances because of the CFC phase out, on the other hand are the minimum recycling rates stipulated by the ordinance on Waste Electrical and Electronic Equipment (WEEE ordinance). Two basic treatment practices can be identified in Austria: One type aiming at a maximum of material recycling and one combining thermal recovery and material recycling. The former does fulfil the mandatory recycling rates, whereas the latter does not fulfil the regulations of the WEEE ordinance. The material and energy balances of the treatment models are established both, for CFC appliances and for appliances containing VOCs. The treatment practices are compared via selected parameters: the cumulative energy demand and relevant emissions. The results show, that a high recycling rate alone does not necessarily lead to goal oriented solutions with respect to the goals of waste management, namely resource conservation and environmental protection.

Learning-Based Energy Management System for Scheduling of Appliances inside Smart Homes
Improper designs of the demand response programs can lead to numerous problems such as customer dissatisfaction and lower participation in these programs. In this paper, a home energy management system is designed which schedules appliances of smart homes based on the user’s specific behavior to address these issues. Two types of demand response programs are proposed for each house which are sh...

Membrane Condenser (MC) is a novel membrane contactor operation recently investigated for the valorization of industrial waste gaseous streams. In particular, until now, it was applied for water recovery from flue gas, cooling tower plumes, etc. More recently, its effectiveness and flexibility in contaminants (such as, NH3 , HF, SO2 ) removal and control from waste gaseous streams was also prov...

THE EFFECT OF COOLING RATE AND AUSTENITE GRAIN SIZE ON THE AUSTENITE TO FERRITE TRANSFORMATION TEMPERATURE AND DIFFERENT FERRITE MORPHOLOGIES IN MICROALLOYED STEELS
Abstract: transformation temperature and different ferrite morphologies in one Nb-microalloyed (HSLA) steel has beeninvestigated. Three different austenite grain sizes were selected and cooled at two different cooling rates for obtainingaustenite to ferrite transformation temperature. Moreover, samples with specific austenite grain size have beenquenched, partially, for investigation on the mic...

Occupancy detection can greatly facilitate heating, ventilation and cooling and lightning control for building energy saving. Sensor-based occupancy detection is usually costly and may suffer from high false positive rates. As such, occupancy detection using load curve data has been proposed. Such methods, however, normally (i) rely on tedious and nontrivial model training process and (ii) do n...
