Problems solved by technology

However, the general subcooling tube is only arranged in the lowermost part of the condenser shell with a conventional condensing tube. The condensing tube is naturally soaked in the condensed refrigerant liquid, and the heat exchange between the refrigerant liquid and the cooling water in the heat exchange tube is not strong. The increase in supercooling is not obvious

Abstract

The invention discloses an efficient condenser which comprises a shell. A condensation heat exchange area and a supercooling area are formed in the shell from top to bottom through a plurality of heat exchange pipes and a supercooling pipe. The condensation heat exchange area is divided into an upper layer and a lower layer. The heat exchange pipes on the upper layer and the lower layer are separated by a fluid baffle penetrating through supporting plates. The whole fluid baffle tilts by 10-15 degrees towards one side in the width direction. The condensation heat exchange area and the supercooling area are separated by a supercooling area upper sealing plate covering the supercooling area. According to the efficient condenser, due to the fact that the fluid baffle is arranged between the upper layer and the lower layer of the condensation heat exchange area and the supercooling area upper sealing plate is arranged between the condensation heat exchange area and the supercooling area, the thickness of fluid films outside the heat exchange pipes below the fluid baffle is effectively reduced, the heat exchange performance of the supercooling area is enhanced, and the energy efficiency of a refrigeration system is obviously improved.

Description

technical field [0001] The invention belongs to the field of refrigeration such as air conditioners, refrigeration and refrigeration, and in particular relates to a condenser. Background technique [0002] As society has higher and higher requirements for energy saving and environmental protection, how to improve the energy efficiency ratio of air-conditioning and refrigeration equipment has become particularly important. At present, in the field of refrigeration and air conditioning, water-cooled shell-and-tube condensers are generally used as the main heat exchange equipment for large-scale central air conditioners and refrigeration units in refrigerated places. The heat exchange efficiency of the condenser directly determines the energy efficiency ratio of the refrigeration unit. Most of the existing shell-and-tube condensers for refrigeration adopt a horizontal structure, and the heat exchange tubes mostly adopt high-efficiency heat exchange tubes with outer ribs and thr...
