display cooler The structural influence of refrigerated food (5)
5) Defrost control of evaporator frost on the evaporator surface will not only increase the heat load of the refrigerated display cooler, but also reduce evaporation The surface heat transfer coefficient of the evaporator reduces the performance of the evaporator and increases the energy consumption of refrigeration. At present, the defrosting of the air cooler basically adopts semi-automatic control or timing defrosting control, which will cause too much heat to be introduced in the defrosting process and cause temperature fluctuations in the refrigerated display cooler. In order to reduce this heat load and achieve energy saving purposes, the defrosting of the air cooler should be fully controlled.
(1) There must be a suitable and reliable frost layer sensor or differential pressure transmitter. In some cases, the display cooler can also use a current transmitter to sense the best defrost time.
(2) There must be a reasonable defrost procedure.
(3) There is also a cooler fin temperature sensor to prevent excessive heating.
(4) More effective defrosting methods for air coolers should be studied and adopted.
5) Real-time calculation and control to ensure that the system runs in the best energy-saving state. When automatic control is adopted, it is best to achieve real-time control, so that the workload of the refrigeration system can be modulated at any time to achieve optimal operation and achieve energy-saving purposes. Automatic control plays a very important role in the implementation of energy-saving display cooler. Many units have invested heavily in energy-saving automatic control operations and have achieved considerable results.
