A shell-and-tube heat exchanger (100) and an air conditioning system are provided by the present application. The shell-and-tube heat exchanger (100) includes: a shell (120) provided with a liquid inlet (122) and an vapor outlet (121), the vapor outlet being disposed at an top portion of the shell; and a heat exchange tube bundle (110) disposed in the shell in an axial direction of the shell; wherein the heat exchange tube bundle includes: a plurality of first heat exchange tubes (111) located at an upper portion, the first heat exchange tubes having a first spacing therebetween; and a plurality of second heat exchange tubes (112) located at a lower portion, the second heat exchange tubes having a second spacing therebetween; wherein the first spacing is different from the second spacing. According to the shell-and-tube heat exchanger (100) and the air conditioning system of the present application, by changing the spacings between upper heat exchange tubes with respect to the spacings between and lower heat exchange tubes, the jet inclination (1) and/or the jet velocity of the medium jet are effectively decreased, or the jet is effectively blocked so that the problem of liquid carryover is alleviated, thereby improving the compressor performance and the system performance.
