摘要:
The invention relates to a storage heat exchanger (12, 12′) including at least one first flow tube (25) and one second flow tube (25) for a heat transfer fluid that respectively include a first end (26) leading into a first manifold (27) and a second end (28) leading into a second manifold (29), the first and second flow tubes (25) being placed adjacent to one another. The storage heat exchanger also includes at least one insert (30) positioned between the first flow tube (25) and the second flow tube (25), the insert (30) consisting of a plurality of blades (31) comprising a first edge (32) contacting the first flow tube (25) and a second edge (33) contacting the second flow tube (25), at least one interstitial space (35) being defined between the insert (30) and the flow tubes (25). The interstitial space (35) is filled with a material for storing calories or frigories.

The invention relates to a heating, ventilating and/or air conditioning system with a main air conditioning loop (10) for a refrigerant including at least one compressor (11), a condenser (12), an expansion device (13) and an evaporator (14), a cold storage heat exchanger (21) suitable for storing cold during operation of the compressor (11), and a secondary air-conditioning loop (20a) comprising the cold storage heat exchanger (21). The secondary air-conditioning loop (20a) is suitable to cool the evaporator (14) when the compressor (11) is out of operation. The secondary air-conditioning loop (20a) includes a fluid circulation branch disposed in parallel with a main air conditioning loop (10) common section including at least the evaporator (14). The fluid circulation branch contains a cold production element (21) able to cool the refrigerant toward the evaporator. The invention is particularly dedicated to heating, ventilating and/or air conditioning systems in “Stop and Start” cars.
摘要:
The invention relates to a heat exchange device including at least two tubes (12) for circulating a heat transfer fluid arranged in at least two rows (R1, R2) offset two-by-two from one row to the other. A heat exchange fin (20) and a heat storage tank (22) made from a heat storage material extend transversely to the rows of the tubes (R1, R2) forming a group of tanks and tubes (24) in each instance, wherein a single heat storage tank (22) is in contact with one tube (12) of each row of tubes (R1, R2). The contact with the tubes (12) takes place alternately on two opposing walls (26, 28) of the heat storage tank (22), and the walls (26, 28) are also in contact with fins (20). The invention can be used for the air-conditioning evaporators of automobiles.
