Abstract
Official abstract text for this publication.
Systems and methods for low ambient air temperature cooling in air-source based heat pump systems wherein an outdoor heat pump unit includes a discharge hood positionable over its fan. The hood including a damper that is openable and closeable as a function of outside temperature. The outdoor unit may also include wind deflectors positioned over the coil openings of the disclosure. During cooling operations below a low outside air threshold temperature, e.g., below 23° F., the damper assembly partially closes to reduce airflow across the condenser coil of the outdoor unit to a level below that which is possible at minimum fan speed. As the outdoor temperature continues to drop, the damper assembly continues to close to further reduce airflow.
First claim
Opening claim text (preview).
What is claimed: 1. An outdoor heat pump unit of a heat pump based air conditioning and heating system comprising: an enclosure that includes side and back panels having respective openings, the opening of the back panel being a coil face exposure opening, a condenser fan mounted on the top of the enclosure and in communication with an interior of the enclosure, the condenser fan configured to draw air in through the openings in the side and back panels of the enclosure and acro…
