The heat pump apparatus 10 comprises a housing 12 having a first 14 and second 24 chamber. The first chamber has a first air inlet 16 and outlet 18, a first heat exchanger 20 and a first fan (22, figure 3) to drive air over the first exchanger. The second chamber has a second air inlet (26, figure 1) and outlet 28, a second heat exchanger and a second fan 32 to drive air over the second exchanger. The second air inlet is an elongate aperture (38, figure 1) in the housing that leads to the second chamber via an inlet passage (40, figure 3) that extends adjacent a side of the housing. A fluid circuit 31 including a compressor 34 and a metering device 33 is provided between the heat exchangers. Ideally, the first air inlet and outlet are connected to a source of outdoor air and the second air inlet and outlet are fluidly communicated with the air of a room to be heated by the apparatus. Noise attenuation material such as open-cell acoustic foam may be provided in the first chamber and in other internal passages. A flame effect panel (58, figure 1) may be included. |
