This paper reports the non-stationary behavior of a roof drainage during experimental measurement in the climate simulator. Many buildings use a fully or partially flat roof where it is necessary to use the roof drainage. Thermal behavior of roof drainage is very important from the point of view of heat transfer and potential condensation. The placement of a roof drain slightly deteriorates thermal transmittance of the roof. This experiment evaluates roof drains in the specific climate simulator where thermal conditions were dynamically controlled in the specific temperature range. The measurement was performed for two types of roof drains. The first drainage is a simple single-shell and the second is double-shell drainage. The results show the effect on the thermal transmittance of the roof section and also the minimal effect of condensation on the non-insulation part of the drainage. Both roof drains showed minimal deterioration of thermal transmittance of the roof construction. © The Authors, published by EDP Sciences, 2017.

The article deals with the use of modern technologies that can improve the thermal comfort in buildings. The article describes the usage of thermal energy storage device based on the phase change material (PCM). The technology improves the thermal capacity of the building and it is possible to use it for active heating and cooling. It is designed as a "green technology" so it is able to use renewable energy sources, e.g., photovoltaic panels, solar thermal collectors, and heat pump. Moreover, an interesting possibility is the ability to use thermal energy storage in combination with a photovoltaic system and thermoelectric coolers. In the research, there were made measurements of the different operating modes and the results are presented in the text. © The Authors, published by EDP Sciences, 2017.

Since proportional-integral-derivative (PID) controllers absolutely dominate the control engineering, numbers of different control structures and theories have been developed to enhance the effciency of PID controllers. Thus, it is essential and inspiring to operate different PID control strategies to the PID2018 Benchmark Challenge. In this paper, a novel control strategy is designed for this refrigeration system, where a feedforward compensator and a conditional integrator are utilized to compensate the disturbances and remove the steady-state error in the benchmark problem, respectively. The simulation results given in the benchmark problem show the straightforward effectiveness of the proposed control structure compared with the existing control methods.

The transparent building element filled with Phase change materials (PCMs) represent an innovative solution that can achieve thermal comfort in buildings lowering the cooling and heating demand. There are many different PCMs which are used in the building element. Salt hydrates can absorb a large amount of energy and have properties similar to water. Nevertheless, these materials have a tendency to supercool (supercooling effect) and to incongruent melt. This paper reports the results of the measurement specific four-pane window filled with a PMCs. Thermal properties of the window were tested in the climate simulator where the climatic conditions were dynamically controlled. The measurement confirmed high thermal inertia of the window and also reducing heat transfer through the window. © The Authors, published by EDP Sciences, 2017.

The paper explores the effect of blinds on the workplace illuminance. The blinds are used to reduce solar load from the sunshine and decrease energy consumption for cooling in the overheated room. With blinds reducing inside illuminance the standards may not be fit and it is necessary add artificial lighting in this cases. It is important to correctly regulate daylight and eventually supplement it with artificial lighting to set the system for minimum energy consumption to meet all standard requirements. This paper presents the basic effect of the blinds on the internal illuminance of the workplace in the laboratory of lighting systems. This paper indicates that with increasing angles of blinds inside illuminance is decreasing. © The Authors, published by EDP Sciences, 2017.

This research used a salt spray booth to generate accelerated corrosion in a copper conductor, AWG 12-gauge purity of 95.95%, this caliber used in residential electrical installations according RETIE Chapter 3 Article 20 and NTC 2050 338. Additionally, to provide an enabling stage of corrosion, type mouse tail splices were made. The amount of corrosion is measured by weight loss, and incidence of corrosion in transport was evaluated from two perspectives: difference active at the beginning and end of the test power, and the change in resistance of the specimen measured at different times of the experiment. The test piece was subjected to a flow of alternating current into a low voltage system, while corrosion occurred. Using two single-phase two-wire electronic meters, the rate of power supply circuit test was recorded, to check for changes in the energy carried from exposure to the corrosive environment wire. The data collected showed that exposure times of the samples in the salt spray chamber involvement was not very noticeable in the copper wire, highlighting small corrosion spots. Similarly, the energy no changes were observed to induce corrosion, however, the resistance of the wire showed a total change of up to 2.4 [milliohms].
