PROJECT INCORPORATING COLD CHAIN 1 5 2 a cost-effective refrigeration meter with two medium-temperature multiplex to ensure accurate readings. In refrigeration plants (plants A and B), effect, these meters primarily measure as well as an Evapco evaporative temperature and pressure, from which condenser with two circuits. For this the used refrigeration units is calculated. project it was important to select a unit This data is also made available to Lynca with a condensing temperature of 35°C Meats, to be used for operational or and air volume control to regulate the management decisions down the line. heat rejection rate. THE SOLUTION three Bitzer semi-hermetic compressors, With the existing system comprising each with a 227kWR capacity. The over 50 simplex cooling systems, the compressors are positioned on one complete upgrade of Lynca Meats’ receiver base and their total capacity is facility started by replacing these units controlled via a CR II system with suction Each multiplex plant is composed of 1. Plant room two — medium temp. 2. Dual evaporative condenser for the medium-temp B and C. 3. eLumac control system on computer. 3 4. Pipe run bridge from plant to building. 5. Multiplex for the medium-temp C. 6. The new plant rooms. 6 4 14 www.coldlinkafrica.co.za COLD LINK AFRICA • May 2019
