Problems solved by technology

[0004] However, several heat exchange tubes are arranged in the condenser in the marine refrigeration system. If all improvements are made according to the above scheme, the improvement cost will be too high; at the same time, the main working mode of the above-mentioned sewage source exchanger is active decontamination. The process of passive decontamination requires a large medium flow rate, which is not suitable for the heat exchange tube of the condenser, and its work is mainly for descaling rather than preventing dirt deposition, and the effect is not good

Abstract

The invention provides a condensing device belonging to the technical field of the refrigeration equipment. The condensing device solves the problems of high cost, bad descaling effect and the like owing to the application of the scaler in the existing sewage source heat exchanger to the ship refrigerating system. The condensing device comprises a condenser body having an inside cavity, and an air inlet mechanism and a liquid outlet mechanism which are arranged at the upper-side air inlet and the lower-side liquid outlet of the body, respectively, wherein a plurality of heat exchange pipes for exchanging heat with a gaseous medium entering the body and a supporting plate for supporting the heat exchange pipes are arranged within the cavity of the body; a plurality of projections and / or pits are formed on the inner walls of the heat exchange pipes; and the projections and / or pits are distributed in the axial direction of the heat exchange pipes and in smooth transition with the pipe walls on both sides thereof. The condensing device has the advantages of high descaling property, high heat exchange efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of refrigeration equipment and relates to a condensing device, in particular to an ammonia condensing device applied to ships. Background technique [0002] A refrigeration system generally includes a compressor, a condenser, a throttle valve, an evaporator, and a refrigerant circulating in the above four components. Ammonia refrigerant is widely used in large and medium-sized refrigeration systems, including refrigeration systems on ships, due to its advantages such as moderate condensation pressure, large cooling capacity per unit volume, small flow resistance and good heat transfer performance. Among them, the ammonia condenser of the four major components is equipped with several heat exchange tubes for heat exchange with the ammonia gas entering the condenser. The heat exchange tubes are easy to condense due to the smooth flow of the internal medium during long-term use. scale, thus affecting the heat ...
