Abstract
A hybrid heat pump system with an indoor unit and a hybrid top/side discharge outdoor unit for continuous heating in a defrosting mode. The hybrid top/side discharge outdoor unit contains heat exchangers and a compressor. The hybrid top/side discharge outdoor unit is divided into an upper compartment and a lower compartment. Bi-directional fans are installed at a boundary between the upper compartment and the lower compartment. The hybrid top/side discharge outdoor unit operates under different modes. In the defrosting mode, the bi-directional fans push air in opposite directions, and airflow due to the bi-directional fans bypasses the compressor in the lower compartment of the hybrid top/side discharge outdoor unit.
Claims20
A hybrid heat pump system for continuous heating in a defrosting mode, the hybrid heat pump system comprises:
- an indoor unit;
- and
- a hybrid top/side discharge outdoor unit with a heat exchanger and a compressor operating under a plurality of modes, wherein:
- the hybrid top/side discharge outdoor unit comprises:
- an upper compartment;
- a lower compartment;
- and
- a plurality of bi-directional fans installed at a boundary in between the upper compartment and the lower compartment,
- the compressor located in the lower compartment of the hybrid top/side discharge outdoor unit, and
- under the defrosting mode:
- the plurality of bi-directional fans pushes air in opposite directions, and
- airflow due to the plurality of bi-directional fans bypasses the compressor in the lower compartment of the hybrid top/side discharge outdoor unit.
A hybrid heating method for continuous heating in a defrosting mode, the hybrid heating method comprises:
- dividing a hybrid top/side discharge outdoor unit into an upper and a lower compartment;
- providing a compressor in the lower compartment;
- providing a plurality of bi-directional fans at a boundary in between the upper compartment and the lower compartment;
- and
- determining a mode of the hybrid top/side discharge outdoor unit, wherein, in the defrosting mode:
- pushing air downwards and upwards from a first fan and a second fan of the plurality of bi-directional fans, respectively, and
- bypassing the air from the compressor in the lower compartment of the hybrid top/side discharge outdoor unit.
A hybrid heat pump system for continuous heating in a defrosting mode, the hybrid heat pump system is operable to:
- divide a hybrid top/side discharge outdoor unit into an upper compartment and a lower compartment;
- position a compressor in a lower compartment of the hybrid top/side discharge outdoor unit;
- operate a plurality of bi-directional fans at a boundary of an upper compartment of the hybrid top/side discharge outdoor unit above the lower compartment;
- and
- determine a mode of the hybrid top/side discharge outdoor unit, wherein in the defrosting mode:
- push air downwards and upwards from a first fan and a second fan of the plurality of bi-directional fans, respectively, and
- bypass the air from the compressor in the lower compartment of the hybrid top/side discharge outdoor unit.
