1518652 Heat pumps; central heating MUST ENERGIE 5 Jan 1977 [14 Jan 1976 26 Oct 1976 3 Nov 1976] 00215/77 Headings F4H and F4U A heat pump utilized both for cooling air and recovering waste heat from air extracted from a building to heat water in a central heating system (not shown) comprises a parallelepiped shaped housing 1 having in its operative position an extracted air inlet 4 in the lower wall and cooled air exhaust orifices 5a, 5b in a side wall, the compressor 9 and condenser 10 forming a refrigerant/water heat exchanger of the refrigerating system being disposed in the housing above and coaxially with the inlet 4. The system also includes an evaporator 7 serving as a refrigerant/air heat exchanger within the housing and an annular space between the exchanger 10 which is of toroidal form and compressor 9 enables inlet air to move upwardly therethrough prior to flow through the evaporator 7 under the influence of a fan (not shown) outside the housing. In a modification, a centrifugal fan is mounted within the housing above the exchanger 10 with its air inlet coaxial with the inlet 4. A box-like collector 11 provides a connection between extraction ducts leading from the building and is removably mounted beneath the inlet 4 in various alternative positions. |
