The system developed at the Institute for Sustainable Technologies – National Research Institute is intended for heat recuperation efficiency tests for recuperators used in ventilation systems in modern, passive buildings. It allows a complex and precise assessment of the efficiency of recuperators, directly influencing the cost of energy used to provide thermal comfort inside a building.
Energy-efficient buildings utilise the potential of renewable sources, among which heat pumps hold an important position. As this technology has a secondary effect on the environment through its noise immission, locations of outdoor units in the exterior should be subjected to the assessment. The present article deals with the options of placing heat pumps in the exterior and the placement assessment methods. The noise burden identification through the assessment of the time exposure is presented in the example of an in situ measurement.
