“…In the tested air circulation system, an additional heat exchanger (a reverse heat exchanger) was used to reverse the thermal processes in the test object. This allows the reduction of the energy intensity of the test, the separation of the two air streams allowing any differentiation of their value, and the autonomous operation of the tested heat exchanger using its own control system [17,18]. Due to the energy efficiency of the systems responsible for the adjustment of the air parameters (temperature and humidity), the system enables the verification of heat exchangers with the nominal efficiency up to 800 m 3 /h.…”

“…One of the methods to significantly reduce the energy consumption of a building is to recuperate the heat in the ventilation system [3,4]. This allows one to reduce the consumption of energy on heating and air-conditioning, and it consist in the application of an air-handling unit with a heat exchanger in which the heat exchange between the air removed from the building and the air blown into the building takes place [5,6,7].…”

“…They were also performed by few laboratories, and they did not give competent information on the actual efficiency of a heat exchanger. The Institute for Sustainable Technologies developed a test stand enabling the verification of performance parameters of heat exchangers complying with the building standards [8,9]. As a result of its implementation, tests on the effectiveness of heat recuperation and flow tests for heat exchangers of the air-air type, intended for ventilation systems, and complete airhandling units with such heat exchangers, became possible [10].…”

The increasing prices of energy and the drive to reduce the emission of greenhouse gases into the atmosphere observed in the recent years have contributed to the intensive development of research on how to reduce the energy consumption of buildings. The confirmations of the current trends are the formal and legal regulations of the European Union that require the buildings to be passive and “zero-energy” in the near future. The introduction of new elements helping one to save energy in the structure of a building requires their formal verification and the confirmation of their safety, effectiveness, and parameters crucial from the point of their application in residential buildings and offices. The authors present an original prototype of an innovative device and a methodology of conducting studies on air-handling units with heat recuperation used in passive and energy-saving buildings. They also discuss the structure and the modus operandi of the system that reconstructs the actual operating conditions of a tested object. The system was used for tests on the tightness of several air-handling units, which also aimed at the verification of their thermal efficiency and the effectiveness of the recuperation of humidity. Air-handling unit tests came from different manufacturers, and they all had the function of heat recuperation. The authors present the results of their investigations that enabled the assessment of the safety of the objects tested, and they also facilitated the comparison of their performance parameters deciding on the energy effect. The tests also formed the foundation for the verification of the developed research system.

“…The conditions in which electromechanical drives operate are closely dependent on the environmental factors [5]; therefore, they can be determined by the climate zone in which they are utilised, or they can be simply associated with some specific requirements. The actuators used in aviation (tail-plane drives) or railroad traffic [6] (railroad gate or switch drives), as well as actuators in demanding fire protection systems [7] (smoke exhaust flap drives), and ventilation systems [8] can serve as examples. Basic climate factors that have an influence on the operation of the elements in question include the temperature and humidity of air, precipitation, wind, and sunlight, out of which the air temperature is in fact the most important, if the device is supposed to be placed outside.…”

The durability and reliability of electromechanical drives is inseparably linked to the broadly defined environmental conditions under which they operate. The design of new solutions characterised by a high level of safety requires the execution of laboratory tests in accordance with the applicable legal regulations, and with a particular focus on the user requirements, that would simulate the actual environment of application. The aim of the research was to develop a test system for electromechanical drives that can be used in particularly demanding systems, e.g. fire protection or process control systems. The hardware and software solutions applied allow one to determine the characteristics (force, displacement, current, and supply voltage as a function of time) in changeable climatic conditions. As part of the verification of the system, the author studied the prototypes of electromechanical ball-screw actuators developed at the Institute for Sustainable Technologies – National Research Institute (ITeE-PIB) and dedicated for the rail traffic control system.

“…In modern facilities, you can now meet various solutions implemented to optimize energy consumption, and thus reduce costs, such as solar panels, ventilation systems with various heat recovery methods, etc. Each of them is specific and should be justified by having a positive impact to manage energy and improve the financial condition of the facility [69,70].…”

Improvement of the energy efficiency of public buildings appears to be one of the best ways to simultaneously reduce energy consumption as well as the negative impacts on the environment. The work is dedicated to the analysis of modernization process of the energy system in a sports facility in a way leading to design of smart energy system. The proposed solution, being a specific case study, offers optimal use of energy in the facility, significantly reducing the demand for energy derived from fossil fuels (heat providers and conventional power plants). The project, on its first step, consists of recovering energy from sewage that usually is irretrievably lost. This option allows to achieve the assumed goals simultaneously optimizing the investment costs. The proposed solution mitigates air pollution and harmful gas and dust emissions to the atmosphere, and contributes to an increase of both the attractiveness and competitiveness of the area in which the sports facility is located. The next step will be further automation of the system and intelligent synchronization of time-dependencies of the processes.
