Abstract
The invention relates to a compact heating assembly of the heat pump type, comprising a heat pump circuit having a compressor, an evaporator and a condenser, wherein the evaporator and condenser parts, together with means for heat exchanging heat carrying fluids against the same, are arranged in a housing. The evaporator and its heat exchanger means and the condenser and its heat exchanger means substantially form an essentially vertical helical conduit system which encloses an inner space, wherein the compressor, possible circulation pumps, etc. are arranged. The device can be burrowed in the ground, and the inner space is accessible via an inspection cover arranged at the top.
Claims9
A compact heat pump unit for heating systems, which is intended to be placed outside a space to be heated, comprising
- a heat pump circuit, including compressor means, evaporator and condenser parts and a heat carrying medium to be circulated in said circuit,
- first heat exchange means for heat-exchanging a first heat-carrying fluid against said evaporator part,
- second heat exchange means for heat exchanging at least one second heat-carrying fluid against said condenser part, and
- a housing enclosing said heat pump circuit and said first and second heat-exchange means, and having access means at the top thereof, said evaporator part together with said first heat exchange means forming a first, substantially vertical helical conduit system, and said condenser part together with said second heat exchange means forming a second, substantially vertical helical conduit system,
- said first and second helical conduit systems being arranged peripherally in the housing so as to define an inner, central space for receiving said compressor means, said space being accessible through said access means.
