Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
54 words
A heat pump comprising an evaporator (1), a compressor (6) and a condenser (9) through which flows a refrigerant, characterized in that said refrigerant is water, said evaporator (1) is equipped with a feedwater control device (3) and a draining device (2), and said condense (9) is equipped with a vacuum generating means (8).
Claim 2
Dependent Claim
54 words
A heat pump comprising an evaporator (1), a compressor (6) and a condenser (9) through which flows a refrigerant, characterized in that said refrigerant is water, said evaporator (1) is equipped with a feedwater control device (3) and a draining device (2), and said condense (9) is equipped with a vacuum generating means (8).
Claim 3
Dependent Claim
24 words
The heat pump according to claim 1, wherein said vacuum generating means exhausts uncondensed air which leaks into the heat pump via the condenser.
Claim 4
Dependent Claim
29 words
The heat pump according to claims 1 or 2, wherein the feedwater device supplies water to compensate for a decrease in the amount of water within the heat pump.
Claim 5
Dependent Claim
31 words
The heat pump according to claim 3, wherein the feedwater device includes a float valve (21) which is actuated when the water level in the evaporator falls below a set level.
Claim 6
Dependent Claim
21 words
The heat pump according to anyone of claims 1 to 3, wherein draining device drains excessive water from the heat pump.
Claim 7
Dependent Claim
29 words
The heat pump according to claim 5, wherein the draining device includes a float valve (21) which is actuated when the water in the evaporator exceeds a predetermined level.
Claim 8
Dependent Claim
36 words
The heat pump according to claim 1; wherein said evaporator includes an inlet means and an outlet means for directing a heat source fluid into and out of a heat exchanger unit located within said evaporator.
Claim 9
Dependent Claim
35 words
The heat pump according to claim 1, wherein said condenser includes inlet means and outlet means for directing a fluid to be heated into and out of a heat exchanger unit located within said condenser.
Claim 10
Dependent Claim
25 words
The heat pump according to claim 1, wherein said compressor compresses heated vapor taken from the evaporator and directs the pressurized vapor into the condenser.
