The extrusion process was described by the changes in extrudate temperature and extruder screw torque, whereas its effectiveness was described by the changes in polymer output, power supplied to the extruder, power conveyed by the polymer, unit energy consumption, and the energy efficiency of the extrusion process.
The investigation of plasticized PVC extrusion conducted using different profile inserts allowed for determining the dependence of the extrudate temperature, extruder screw torque, polymer output, power supplied to the extruder and conveyed by the polymer, unit energy consumption and energy efficiency of the extrusion process on the feed pocket depth, and screw speed.
The lowest unit energy consumption in the whole investigated range of the extruder screw speed was observed for the highest investigated feed pocket depth.
To include details of the dimensions of each piece of equipment, sample layouts for a 9 bin unit energy consumption
profile (to cover consumption in watts when in sleep mode, when idle and when engaged), and any special accommodation requirement.
The approach involved evaluating a number of MELs chosen based on their "Active Power Draw," Unit Energy Consumption
(UEC), and Annual Energy Consumption (AEC).
In this study, the effect of ventilation on indoor temperature control, thermal comfort, outdoor unit energy consumption, and the efficiency of the multisplit VRV system and energy saving options are investigated numerically with the multisplit VRV module obtained from the literature (Zhou et al.
As shown in Figure 5, in order to keep the indoor temperatures at the set temperature, the outdoor unit energy consumption increases as the outdoor temperature increases.
The implied reduction of 30% in unit energy consumption
over three years seems implausible, despite the rapid growth of computer manufacture and other activities with low unit energy consumption
,'' he said.
In order to evaluate the effect of ventilation on indoor temperature control, thermal comfort, outdoor unit energy consumption, and the CPF of the multi-split VRV system, parametric tests were performed with HRV units except on Tuesday and without ventilation on Tuesday, respectively, in the cooling seasons of 2006 and 2007.
Since most of the outdoor temperatures were higher than the set temperature of 25[degrees]C during the cooling season, as shown in Figure 3b, the benefit of ventilation on the outdoor unit energy consumption of the multi-split VRF system was little.
