2. If added to the heat pump of an electric furnace, the heat pump coil can usually be placed at the maximum efficiency of the furnace on the cold side (upstream).
3. The outdoor unit should be protected from strong winds, which may reduce efficiency and cause defrosting problems. At the same time, it should be placed open so that outdoor air does not recirculate through the coil.
4. In order to prevent snow from blocking the airflow in the coil and allowing defrosting to drain, the unit should be placed on a base that raises the ground 30-60 cm (12 to 24 inches) or more. It should be fixed on the concrete slab, which in turn sits on the bed of gravel to enhance the drainage stand. Or, the unit may be installed to construct the appropriate frame on the house from the wall.
5. It is advisable to locate the heat pump drip line outside the house (water drop roof area) to prevent ice and water from falling, which can reduce airflow or cause damage to the fan or motor.
6. The drain of the inner floor of the house must be connected to the inner coil of the inner coil to ensure that the condensate, the form of the drain on the coil is correct.
7. The hot air pump should be placed, therefore, the maintenance personnel have enough space to work in the unit.
8. The refrigerant line should be as short and straight as possible. It is good practice to insulate the wire to minimize unnecessary heat loss to avoid condensation.
9. Fans and compressors make noise. Find outdoor units that are far from windows and adjacent buildings. Some units have extra noise when they vibrate. You can reduce this noise absorption based on the choice of low noise equipment or installation units.
10. Heat pump systems generally require larger duct sizes than other central heating systems, so existing piping may have to be modified. For proper heat pump operation, the airflow should be 50 to 60 liters per second per watt (liters per second), or 400 to 450 cubic feet per minute (cfm) per ton, cooling capacity. "
