Abstract

The invention provides a shell and tube heat exchanger and an air conditioning system. The shell and tube heat exchanger comprises a shell and a heat exchange tube bundle; the shell is provided with a liquid inlet and an air outlet, and the air outlet is formed in the top of the shell; the heat exchange tube bundle is arranged in the shell in the axial direction of the shell; and the heat exchange tube bundle comprises a plurality of first heat exchange tubes located on the upper portion and a plurality of second heat exchange tubes located on the lower portion, first intervals are formed between the first heat exchange tubes, and second intervals are formed between the second heat exchange tubes, wherein the first intervals are different from the second intervals. According to the shell and tube heat exchanger and the air conditioning system, by changing the distances between the heat exchange tubes on the upper portion and the heat exchange tubes on the lower portion, the jet flow inclination angle and / or the jet flow speed of medium jet flow are / is effectively reduced, or the jet flow is effectively blocked, the problem that air suction carries liquid is solved, and then the compressor performance and the system performance are improved.

Description

technical field [0001] The present application relates to the field of air conditioning, and more specifically, the present application relates to an air conditioning system and a shell-and-tube heat exchanger used therein. Background technique [0002] Air-conditioning equipment belongs to a well-developed technical field, which plays a role in regulating air temperature and humidity. Generally speaking, air conditioning equipment includes compressors, throttling components, and heat exchangers that serve as condensers and evaporators respectively. The heat exchangers provide heat exchange space for refrigerants and external fluids. As a common type of heat exchanger, the shell and tube heat exchanger has the advantage of high heat transfer performance. But at the same time, alleviating the problem of liquid carryover is an important challenge in the structural design of shell-and-tube heat exchangers, because such phenomena will seriously affect the performance of the com...
