AIR CONDITIONING DEVICE
Document Type and Number:
Japanese Patent JP2016099056
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an air conditioning device capable of improving imbalance of heat exchange amounts among supercooling heat exchangers.SOLUTION: In an air conditioning device, a heat exchanger capacity of a first supercooling heat exchanger 25a close to a refrigerant inlet A is smallest, and the heat exchange capacities are increased from a second supercooling heat exchanger 25b toward a third supercooling heat exchanger 25c. Concretely, in the first supercooling heat exchanger 25a, five first split flow channels 25a1 are disposed, in the second supercooling heat exchanger 25b, seven first split flow channels 25b1 are disposed, and in the third supercooling heat exchanger 25c, eleven first split flow channels 25c1 are disposed. Thus the heat exchange capacity of the first supercooling heat exchanger 25a where a heat transfer area of the first split flow channels 25a is minimum, becomes smallest. By increasing the number of first split flow channels from the second supercooling heat exchanger 25b toward the third supercooling heat exchanger 25c, the heat transfer area is successively increased, and the heat exchange capacity is successively increased.SELECTED DRAWING: Figure 2
