Mango FAQ

Screening adds resistance to airflow, and its effect depends on open area and installation rather than the protected opening's dimensions alone. Check ventilation performance after fitting it and keep the material clean. A fan that previously controlled temperature may deliver less air through the screened system, so pest exclusion and climate control need to be evaluated together.

A wet-bulb reading depends on water evaporating correctly from the thermometer's wick under the specified airflow. A dry wick no longer supplies that cooling process, and contamination can also affect the measurement. Maintain the instrument according to its observing procedure before calculating humidity. Two thermometer readings alone are not sufficient if the wet-bulb setup is not functioning as intended.

The coefficient of performance compares useful heat delivered with the electrical energy consumed under specified operating conditions. It is not a fixed promise of savings throughout winter, because outdoor temperature, defrosting, and the installation affect performance. Compare ratings at conditions relevant to the shelter and evaluate total heating needs rather than selecting equipment from its best advertised coefficient alone.

Airflow ratings depend on the resistance against which the fan operates. Shutters, screens, pads, and restricted inlets change that resistance, so the advertised free-air output may not be delivered in the actual house. Match equipment to the complete installation and verify performance. A large nominal fan size does not establish adequate air exchange around sheltered mango trees.
