Description

Technical Field

[0001] The utility model relates to the technical field of shell and tube condensers, in particular to a shell and tube condenser supercooling device. Background Art

[0002] The condenser is one of the four major components of the refrigeration and air-conditioning system. Its function is to condense the high-temperature and high-pressure gaseous refrigerant discharged from the compressor into a high-pressure and medium-temperature liquid refrigerant in the refrigeration (heat) cycle. Generally, the condenser must ensure a supercooling degree of more than 5K so that the system can operate stably and reliably. The bottom of the traditional shell and tube condenser generally leaves a small amount of space as a liquid storage device or supercooling, and the bottom space is not fully utilized. An economizer must be additionally installed on the system to achieve effective supercooling. Although it has a supercooling effect, it does not meet the requirements of today's society to promote energy conservation and environmental protection. Although many shell and tube condensers are now equipped with supercooling tubes at the bottom, they do not have a supercooling effect at all and have no supercooling. Although some have supercooling, the supercooling provided is far from 5K or above, and it is difficult to ensure a relatively stable supercooling degree. This results in poor heat exchange of the refrigerant entering the evaporator, and the cooling (heating) capacity is not fully utilized.

[0003] In order to solve the above technical problems, a Chinese patent with announcement number CN204739807U in the prior art discloses a subcooling device for a shell and tube condenser, which is located at the bottom of the shell and tube condenser cylinder. The subcooling liquid baffle is horizontally arranged and welded to the cylinder. The baffle assembly and the heat exchange tube bundle are placed below. The baffles are arranged in an alternating manner with notches to increase the travel of the liquid refrigerant.

[0004] Although the above-mentioned prior art solution prolongs the heat exchange time between the liquid refrigerant and the refrigerant in the heat exchange tube bundle, the multiple groups of baffles inside the device are positioned by multiple groups of fastening nuts. During assembly, the staff needs to reach into the inside of the condenser and rotate each group of fastening nuts one by one to fix them. The operation is cumbersome, which increases the workload of the staff and reduces work efficiency. Utility Model Content
