Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
100 words
Refrigeration machine circuit comprising a compressor, a condensor, a fan for blowing air over said condensor, an evaporator, a cold water circuit which is in heat change relationship with said evaporator, and a refrigeration storage device, characterized in that said refrigeration storage device contains a storage mass which crystallizes at a temperature above 0* C. and below 8* C., which is in good heat conducting communication with the evaporator, and which has water from the cold water circuit playing on it and in thermal contact with it such that heat may be transferred from said water to said storage mass.
Claim 2
Dependent Claim
100 words
Refrigeration machine circuit comprising a compressor, a condensor, a fan for blowing air over said condensor, an evaporator, a cold water circuit which is in heat change relationship with said evaporator, and a refrigeration storage device, characterized in that said refrigeration storage device contains a storage mass which crystallizes at a temperature above 0* C. and below 8* C., which is in good heat conducting communication with the evaporator, and which has water from the cold water circuit playing on it and in thermal contact with it such that heat may be transferred from said water to said storage mass.
Claim 3
Dependent Claim
26 words
Refrigeration machine circuit according to claim 1, characterised in that the storage mass forms a hydrate which contains more than 8 Mol of water of crystallisation.
Claim 4
Dependent Claim
27 words
Refrigeration machine circuit according to claim 1, characterised in that the storage mass forms a hydrate of an ionogenic material which contains a variety of metal ions.
Claim 5
Dependent Claim
20 words
Refrigeration machine circuit according to claim 1, characterised in that the storage mass is arranged in thin-walled, vertically extending vessels.
Claim 6
Dependent Claim
17 words
Refrigeration machine circuit according to claim 4, characterised in that the vessels consist of thin flexible tubes.
Claim 7
Dependent Claim
18 words
Refrigeration machine circuit according to claim 4, characterised in that the vessels form a unit with evaporator channels.
Claim 8
Dependent Claim
22 words
Refrigeration machine circuit according to claim 6, characterised in that the evaporator channels are formed by a double walled sheet metal plate.
Claim 9
Dependent Claim
23 words
Refrigeration machine circuit according to claim 7, characterised in that the sheet metal plates support the storage mass and are substantially in tension.
Claim 10
Dependent Claim
50 words
Refrigeration machine circuit according to claim 8, characterised in that the sheet metal plates which are arranged side by side in a container are so relatively displaced in height that above and below the plates channels are formed which taper when viewed at right angles to the sheet metal plates.
