Refrigeration system, and condenser for use in decompressing-tube system

A refrigeration system having a refrigeration cycle, said refrigeration system comprising:

• a compressor for compressing a refrigerant;
• a condenser for condensing the refrigerant compressed by said compressor;
• a decompressing tube for decompressing the refrigerant condensed by said condenser;
• an evaporator for evaporating the refrigerant decompressed by said decompressing tube;
• and
• an accumulator for separating a gaseous refrigerant from the refrigerant evaporated by said evaporator,
• wherein said condenser includes:
• a pair of headers disposed in parallel with each other at a certain distance;
• a plurality of heat exchanging tubes disposed between said pair of headers with opposite ends thereof connected with said headers;
• a partition provided in said header to group said plurality of heat exchanging tubes into a plurality of passes constituting a refrigerant passage through which the refrigerant passes in turn, said plurality of passes including a first pass and a final pass;
• and
• decompressing means which is disposed at a part of said refrigerant passage between said first pass and said final pass to decompress the refrigerant passing through said decompressing means.

A condenser for use in a decompressing-tube system constituting a refrigeration cycle which includes a compressor, a decompressing tube, an evaporator and an accumulator, said condenser comprising:

• a refrigerant inlet for introducing a refrigerant;
• a refrigerant outlet for discharging the refrigerant;
• a refrigerant passage for leading the refrigerant introduced from said refrigerant inlet to said refrigerant outlet while condensing the refrigerant;
• and
• decompressing means which is provided at a part of said refrigerant passage to decompress the refrigerant passing through said decompressing means.
