Heat Pump Install Air Flow Requirements
The performance and efficiency of a heat pump is directly correlated to its ability to freely draw outside ambient air through its intakes and discharge air via the exhaust fan outlet without obstruction.
When a heat pump is heating the exhaust fan discharges cold air, when it is cooling it discharges warm air. Avoid installing in an area with confined air space (i.e. under a deck or in a room) even if that confined space has ventilation. When the heat pump is operating, in a short space of time it will significantly decrease/increase the temperature of that confined air volume which in turn will reduce the efficiency and heating/cooling performance output of the heat pump. Altered environmental conditions due to confined space also put additional stress on the major components, making them work harder which could reduce expected life span and reliability of the product.
Obeying the below recommended air space requirements and preventing any restriction to air flow is critical to achieve optimal performance and COP output.
