Abstract
Abstract A heating installation in which heat from the environment is fed to a consumer by means of a heat pump while the compressor of the heat pump is driven by a turbine which is located in the circuit of a further heat carrier which is heatable by a heat source, the energy of which in case of need is directly transferable to the consumer of the heating installation.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
127 words
A heating installation comprising a first circuit with a first heat carrier, a second circuit for heating the first heat carrier and with a second heat carrier in the form of a low boiling coolant, said second circuit comprising a heat pump and a compressor, a prime mover for driving said compressor, a third circuit with a third heat carrier for driving said prime mover, a fourth circuit with a fourth heat carrier heatable by a heat source and for heating said third heat carrier, said second and third heat carriers being separated from each other, an evaporator provided in said second circuit, said evaporator being feedable with heat from the environment, and means adapted to establish direct heat exchange between said first and fourth heat carriers.
Claim 2
Dependent Claim
127 words
A heating installation comprising a first circuit with a first heat carrier, a second circuit for heating the first heat carrier and with a second heat carrier in the form of a low boiling coolant, said second circuit comprising a heat pump and a compressor, a prime mover for driving said compressor, a third circuit with a third heat carrier for driving said prime mover, a fourth circuit with a fourth heat carrier heatable by a heat source and for heating said third heat carrier, said second and third heat carriers being separated from each other, an evaporator provided in said second circuit, said evaporator being feedable with heat from the environment, and means adapted to establish direct heat exchange between said first and fourth heat carriers.
Claim 3
Dependent Claim
16 words
The installation of claim 1, wherein the second heat carrier is the same as the third.
Claim 4
Dependent Claim
42 words
The installation of claim 1, wherein the second and/or third heat carrier is trichlorofluoromethane (CCl 3 F), dichlorodifluoromethane (CCl 2 F 2 ), chlorodifluoromethane (CHClF 2 ), dichlorotetrafluoroethane (C 2 Cl 2 F 4 ) or octafluorocyclobutane (C 4 F 8 ).
Claim 5
Dependent Claim
42 words
The installation of claim 2, wherein the second and third heat carrier is trichlorofluoromethane (CCl 3 F), dichlorodifluoromethane (CCl 2 F 2 ), chlorodifluoromethane (CHClF 2 ), dichlorotetrafluoroethane (C 2 Cl 2 F 4 ) or octafluorocyclobutane (C 4 F 8 ).
Claim 6
Dependent Claim
37 words
The installation of claim 3, wherein for operating of the evaporator of the heat pump at an evaporating temperature of 0° C. or below, the second and/or third heat carrier is octafluorocyclobutane (C 4 F 8 ).
Claim 7
Dependent Claim
37 words
The installation of claim 4, wherein for operation of the evaporator of the heat pump at an evaporating temperature of 0° C. or below, the second and third heat carrier is octafluorocyclobutane (C 4 F 8 ).
Claim 8
Dependent Claim
37 words
The installation of claim 3, wherein for operation of the evaporator of the heat pump at an evaporating temperature above +5° C., the second and/or third heat carrier is dichlorotetrafluoroethane (C 2 Cl 2 F 4 ).
Claim 9
Dependent Claim
37 words
The installation of claim 4, wherein for operation of the evaporator of the heat pump at an evaporating temperature above +5° C., the second and third heat carrier is dichlorotetrafluoroethane (C 2 Cl 2 F 4 ).
Claim 10
Dependent Claim
12 words
The installation of claim 1, wherein the prime mover is a turbine.
Claim 11
Dependent Claim
16 words
The installation of claim 9, wherein the turbine and compressor are seated on a common shaft.
Claim 12
Dependent Claim
23 words
The installation of claim 9, comprising means for supplying the condensation heat of the third heat carrier directly to the first heat carrier.
Claim 13
Dependent Claim
23 words

Claim 14
Dependent Claim
27 words
The installation of claim 1, including means for supplying residual warmth from the heat source or warmth from an external heat source to the third heat carrier.
Claim 15
Dependent Claim
21 words
The installation of claim 1, including a heat exchanger for transmitting heat from the fourth heat carrier to the first carrier.
Claim 16
Dependent Claim
23 words
The installation of claim 1, comprising an additional interpolated heat pump for transmitting the heat from the second carrier to the first carrier.
Claim 17
Dependent Claim
19 words
The installation of claim 15, wherein said additional interpolated heat pump has a compressor driven by an additional turbine.
Claim 18
Dependent Claim
21 words
The installation of claim 15, including means for supplying the condensation heat of the additional turbine to the first heat carrier.
