Laboratory for testing and optimization of operating parameters of central heating, ventilation and air conditioning system (HVAC) elements

Research stand allows the analysis and validation of new constructional solutions for central heating, ventilation and air conditioning systems, as well as optimizing solutions that reduce energy consumption during operating the system while maintaining the thermal comfort parameters.
The laboratory consists of a closed, airtight test chamber; an open heating circuit which supplies the tested HVAC components; a cooling / heating system of internal walls for stabilization of the parameters inside the chamber; measurement and control equipment and tools for numerical evaluation of the analysed components.
The scope of lab activities includes:

  • measurement of heating and cooling power of radiators, fan coils and air conditioners,
  • optimization of operating parameters of radiators (in heating and cooling mode), fan coils and air conditioners,
  • determination of temperature and enthalpy efficiency of recuperators,
  • laser speed measurement of supply elements and fans,
  • design and printing of photopolymer components.

Laboratory stand for testing conduit sterilization and air-cleaning devices in ventilation and air conditioning systems and secondary leaching of pollutants from filter surfaces

Based on indications included in ASHRAE Standard 52.2-2007 “Method of Testing General Ventilation Air-Cleaning Devices for Removal Efficiency by Particle Size” regarding the determination of the capacity of devices to remove pollutants from air as well as their resistance to air flow, a unit consisting of three identical modules has been built. Each module allows to maintain air stream ventilating in the range of 0-800 m3/h, airflow temperature of +15 ÷ 40oC and relative air humidity of 30-70%.

Types and range of conducted research:
  • the analysis of effectiveness of conduit sterilization and air-cleaning devices in terms of selected microbiological pollutants (bacteria, fungi);
  • research on the influence of aging of UV lamps used in conduit sterilizers and of the frequency of switching on and off on the effectiveness of air cleaning process;
  • research on secondary leaching of pollutants from filter materials.
