Heating system for buildings - uses heat pumps, supplied by buried heat store, with air heated in double solar pipes

摘要

The unit supplies buildings with energy and uses heat pumps, heat stores, and solar cells. Heat pumps contg. two pistons with armatures supply current synchronously to the armatures and to coils around the cylinders, via two guide rods with sliding contacts, which project from the cylinder ends. Piston acceleration produces high pressures in the compression chamber. Alternately, the pump may have a semi-circular tube with two end cylinders, and a piston, which is connected to a shaft via a metal arm. The arm supplies current to the piston armature. The shaft carries a disc connected via a rod to the flywheel of an electric motor. The pump is supplied with warm air from heat store, which is ca. 5m below ground level and consists of stones with heating-and draught channels, and has a heat-insulating brick cladding. The air in the store is heated by a system of solar pipes in the garden, consisting of double plastics pipe with intermediate air space, the inner pipe having a dark lower side.
