Click the Charge button to open the low side hand wheel on the gauge set and start charging. Now keep the system idle for 5 minutes to check there is no pressure drop. Types of reefers: Reefer ships may be categorised into three types: Side-door vessels have water-tight ports on the ship's hull, which open into a cargo hold. While in operation, the refrigerant used in the refer plant gets consumed or is reduced in quantity because of leakage in the system. This layer controls our climate & protects us from radiation. Once vacuum is reached, close the valve of charge cylinder in the valve block, 4. Do not overfill the system. "Basic Refrigeration and Charging Procedures" Interactive CD-ROM is based upon the book "Basic Refrigeration and Charging Procedures" by ESCO Press. 2. Thanks you so much for this site. Reduction in quantity of refrigerant may lead to troubles in the plant such as-. However, just like all other machinery on ships, the refrigeration system can also get into some trouble from time-to-time. 2. When being transported over the road on a trailer or over rail wagon, they can be powered from diesel powered generators ("gen sets") which attach to the container whilst on road journeys. This will remove all the air inside the pipe. FYI – Liquid charging of refrigeration systems is preferred through filter/dryer. HVACR training book that covers Refrigerant Charging/Troubleshooting Practices, Step by Step Procedures for preparing an air conditioning and heat pump system for refrigerant, reading the manifold gauge set, measuring the refrigerants charge level, and troubleshooting problems with the system’s refrigerant … In-depth examples of pressure and temperature measurements are used to help in a … why you need to shake the bottle or turn it upside down, when you charging refrigerator plant? Charging Part 2. Detailed explanations of the refrigerant pressures and temperatures at each point in the refrigeration cycle will clarify questions the reader may have when troubleshooting a compression system. After remedy the fault, it must, If compressor stops due to a fault, the master solenoid valve will close to prevent flooding by. as to prevent hot air going into cargo spaces. How to Charge Refrigeration Plant on Ships? Some of these problems are common but require immediate attention. When recharging, refrigerant gas should be added in small increments to avoid overloading the system. How to remove air from the refrigerent system. To prevent the condensing of moisture on cargo or hull. Manufacturers create a great deal of resources for technicians to ensure their equipment is dialed-in correctly.
