Manufacturers of rotary heat recovery units describe them as a very high efficiency heat recovery ventilation systems. In a real system this device is not usually operated under optimal conditions. This is due to the daily and annual changes in temperature and relative humidity. In order to determine the parameters of the rotary heat exchanger mathematical model was constructed and then implemented in a development environment. The paper presents the modeling results of job recovery unit working in real conditions with regard to changes in temperature, air velocity and rotor speed. It turns out that on each of the parameters affects the efficiency of the heat recovery process, which demonstrate that the heat exchanger for the better part of the year will be working with much less efficiency than the nominal.
