Description

Technical Field

[0001] This utility model relates to the field of evaporative condenser operation control technology, and in particular to an evaporative condenser venting device and system based on a refrigeration system. Background Technology

[0002] Evaporative condensers are the main heat exchange equipment in refrigeration systems. The superheated, high-pressure refrigerant gas (working fluid) discharged from the compressor in the refrigeration system exchanges heat with the sprayed water and air outside the evaporative condenser through the condenser coils. The gaseous refrigerant enters the condenser coils from the top and is gradually condensed into liquid refrigerant from top to bottom. The powerful airflow from the accompanying induced draft fan ensures that the sprayed water completely and evenly covers the surface of the condenser coils. The water, aided by the airflow, greatly improves the heat exchange effect. Some of the heated sprayed water turns into gas, and the latent heat of vaporization of water is used to carry away a large amount of heat with the airflow. Water droplets in the hot air are trapped by a high-efficiency dehydrator, and together with the remaining water that has absorbed heat, they fall into the PVC water-spraying heat exchange layer, where they are cooled by the flowing air, lower their temperature, and enter the water tank, where they are then circulated by a circulating water pump.

[0003] Evaporative condensers inevitably produce non-condensable gases (such as air) during operation. The accumulation of these non-condensable gases can lead to increased internal condensing pressure and increased power consumption in the refrigeration unit. Therefore, it is necessary to periodically vent these evaporative condensers. Evaporative condensers are typically installed on the roof of a machine room or warehouse, with a vent valve located at the highest point of the main refrigerant pipe. Traditionally, venting requires operators to climb to the roof to manually operate the vent valve and release the non-condensable gases from the evaporative condenser. This method is not only cumbersome but also unsafe. Utility Model Content
