An energy recovery system (10) including a greenhouse (12) including at least a boundary (14) area made of a material which is substantially transparent to solar radiation, thus to capture solar energy in the internal environment of the greenhouse (12), a heat pump (15) including a closed fluid circuit which includes a first source heat exchanger (18) in which heat from the internal environment of the greenhouse (12) is transferred to the fluid, a second sink heat exchanger (20) in which heat from the fluid is transferred to a heat energy store (24), and an impeller (22) for moving the fluid from the first heat exchanger (18) where the fluid is at a generally lower pressure to the second heat exchanger (20) where the fluid is at a generally higher pressure, power to drive the impeller (22) being derived solely from the energy stored. |
