Compressor based units can be used to dehumidifyany(reasonably) sized space atanyhumidity level. Most thermo-electric and desiccant units can only be used to dehumidify small spaces (like a closet, for example) and only if the humidity level in that space isn’t very high. Because thermo-ele...

Active Line Modules can supply energy to the DC link and return regenerative energy to the supply system. A Braking Module and braking resistor are required only if the drives need to be decelerated in a controlled manner after a power failure (i.e. when energy cannot be recovered to the ...
A drop in the heating efficiency of an HVAC system ranges from malfunctioning parts to components needing re-calibration. Indoor Humidity: A drastic increase in humidity levels in your home is often the symptom of an HVAC needing maintenance upgrades. Increased discomfort and stuffiness are often ...
36 a & b. This deformation is considered an autogenous strain as the specimens could only exchange a minimum amount of humidity with the surrounding environment while the measurements were taken. Conventional mortars and mortars with CBA1 show a quite stable performance. However, the mortars with ...
For all experiments, we used four- to seven-day-old virgin flies collected from density-controlled bottles seeded with eight males and eight females. Fly bottles were kept at 25 °C and 60% relative humidity. Virgin flies were housed individually and kept in behavioural incubators under a 12...

Humidity equilibration experiments were carried out on two of the samples to determine how long the samples take to equilibrate with the surrounding environmental conditions. Small chamber experiments were then conducted to measure emission factors for the four surface materials at various temperature and...
As an additional measure for installation altitudes from 2000 m up to 5000 m, an isolating transformer is required in order to reduce transient overvoltages according to EN 60664‑1. For additional information, please refer to the SINAMICS Low Voltage Engineering Manual. ...
