Abstract
Official abstract text for this publication.
A heat exchanger includes a plurality of refrigerant flow paths separated by a distributor and is configured to allow a refrigerant inflow amount to each of the plurality of refrigerant flow paths to be adjusted by a pressure loss in a corresponding one of a plurality of capillaries connected between the distributor and the plurality of refrigerant flow paths. Inner diameters of the plurality of capillaries are limited to two types. An inner diameter of one type of the plurality of capillaries having a larger inner diameter is 1.3 to 1.6 times larger than an inner diameter of an other type of the plurality of capillaries having a smaller inner diameter.
First claim
Opening claim text (preview).
The invention claimed is: 1. A heat exchanger comprising a plurality of refrigerant flow paths separated by a distributor, the heat exchanger is configured to allow a refrigerant inflow amount to each refrigerant flow path of the plurality of refrigerant flow paths to be adjusted by a pressure loss in a corresponding one capillary of a plurality of capillaries which is connected between the distributor and the each refrigerant flow path of the plurality of refrigerant flow paths, inner diameters of the plurality of capillaries being limited to two types, an inner diameter of one type of the plurality of capillaries having a larger inner diameter being 1.3 to 1.6 times larger than an inner diameter of another type of the plurality of capillaries having a smaller inner diameter, wherein there are at least three capillaries in the plurality of capillaries, wherein the capillaries having the larger inner diameter all have the same larger inner diameter and have different lengths. 2. The heat exchanger of claim 1 , wherein outer diameters of the plurality of capillaries are standardized to a same outer diameter. 3. The heat exchanger of claim 2 , wherein the plurality of capillaries are sorted into the two types corresponding to the inner diameters and disposed to the distributor. 4. The heat exchanger of claim 1 , wherein the two types of the plurality of capillaries having different inner diameter are marked in different colors corresponding to the types. 5. The heat exchanger of claim 1 , wherein one of the two types of the plurality of capillaries having the different inner diameters is provided with a marking. 6. A refrigeration cycle apparatus comprising at least a compressor, a condenser, a pressure reducer, and an evaporator connected in a closed loop by a refrigerant pipe, wherein the heat exchanger of claim 1 is used as the evaporator. 7. The heat exchanger of claim 2 , wherein the two types of the plurality of capillaries having different inner diameter are marked in different colors corresponding to the types. 8. The heat exchanger of claim 3 , wherein the two types of the plurality of capillaries having different inner diameter are marked in different colors corresponding to the types. 9. The heat exchanger of claim 2 , wherein one of the two types of the plurality of capillaries having the different inner diameters is provided with a marking. 10. The heat exchanger of claim 3 , wherein one of the two types of the plurality of capillaries having the different inner diameters is provided with a marking.
