Description

A low-temperature cascade evaporative condenser

Technical field

0001. This utility model relates to the technical field of evaporative condensers, specifically a low-temperature cascade evaporative condenser.

Background technique

0002. The evaporative condenser is a heat exchange device used for cooling in cold storage. It is composed of a fan, condensation coil, heat exchange fins, box and other components. The evaporative condenser is the main heat exchange equipment in the refrigeration system. , its working principle is: the superheated high-pressure refrigerant gas discharged from the compressor in the refrigeration system passes through the condensation discharge pipe in the evaporative condenser, so that the high-temperature gaseous refrigerant exchanges heat with the spray water and air outside the discharge pipe; that is, The gaseous refrigerant enters the discharge pipe from the upper port and is gradually condensed into liquid refrigerant from top to bottom. The super strong wind force of the induced draft fan makes the spray water completely and evenly cover the coil surface. The water takes advantage of the wind force, which greatly improves the efficiency of the coil. Heat exchange effect: The spray water with increased temperature changes from part to gaseous state, and the latent heat of vaporization of water is used to take away a large amount of heat by the wind. The water droplets in the hot air are intercepted by the high-efficiency dehydrator, and are scattered with the rest of the water that has absorbed the heat. In the heat exchange layer of the PVC water spray sheet, it is cooled by the air flowing through it. After the temperature decreases, it enters the water tank and then continues to circulate through the circulating water pump. The moisture evaporated into the air is automatically replenished by the water level regulator.

0003. The existing water tank of the low-temperature cascade evaporative condenser lacks an automatic scale cleaning structure. After the water tank is used for a long time, the inner wall of the water tank will be contaminated with a large amount of attachments, which affects the overall water quality and has a certain impact on the overall operation. In addition, the existing low-temperature cascade evaporative condenser cannot spray the condensation coil evenly due to the spray port, and the spray water cannot completely and evenly cover the surface of the condensation coil, which affects the heat exchange effect and gives People's use process has brought certain adverse effects. For this reason, we propose a low-temperature cascade evaporative condenser.
