Abstract:

The work concerns the efficiency of dispersed recuperation in a single-family building by analyzing functional errors (work anomalies) and non-normative error by calculations using the validation method. Three recuperators were checked for tests, each device was placed in a different room, with a different volume. The work carried out thermographic tests of the recuperator, then the obtained results were checked in the authorized "FLIR" program and subjected to calculations of the validation method. The study period lasted 10 days, thermographic images of each recuperator were taken twice a day in the morning and evening. The obtained results showed that the recuperator was not properly selected in the salon, the room was oversized to the device. The recuperator in the upstairs bedroom operates on an acceptable edge, depending on the weather conditions outside. The recuperator in the ground floor bedroom was selected correctly, which results from the results obtained calculated on the basis of the validation method.
