What is the reason for the high energy consumption of medical chillers?

1. Run time

If the operating time of GX/GY -65°C ~ -10°C Industrial Refrigerators is relatively long, and the company does not provide sufficient rest time for the equipment during the operation of medical refrigerators, the safety of using medical refrigerators by the company will also be threatened.

Therefore, it is recommended that enterprises can develop a reasonable plan for the operating time of medical refrigerators, or alternatively operate by installing multiple medical refrigerators.

2. Fault

If there is a malfunction in the medical refrigerator, and the cooling performance of the medical refrigerator continues to decrease, enterprises should be cautious when using medical refrigerators. When operating equipment, if enterprises ignore the existence of various common faults, although they can temporarily use medical refrigerators normally, the safety of equipment operation is directly affected.

3. Environment

When enterprises use medical refrigerators, if there are many unsuitable factors in the environment, the energy consumption of medical refrigerators will also continue to increase.

Therefore, it is necessary to choose a place with a good environmental location and a workshop with sufficient space. It is necessary to install the medical refrigerator at the corners or in the middle. Only in this way can the correct location be selected and can the enterprise efficiently complete the task.

4. As the evaporation temperature decreases, the compression ratio of the compressor increases, and the unit energy consumption for production cooling increases.

When the evaporation temperature decreases by 1 ° C, it consumes 3% to 4%. Therefore, minimizing the evaporation temperature difference and increasing the evaporation temperature not only saves energy consumption but also increases the relative humidity of the cold chamber.

5. With the increase of condensation temperature, the compression ratio of the compressor and the energy consumption per unit of refrigeration capacity of the water cycle freezer increase.

The condensation temperature is between 25 ° C and 40 ° C, and for every 1 ° C increase, the power consumption increases by approximately 3.2%. Therefore, it is generally necessary to clean the condenser of the water circulation freezer after 3 to 6 months.

6. When the heat exchange surface of the condenser and evaporator is covered with a layer of oil layer, the condensation temperature increases and the evaporation temperature decreases, resulting in a decrease in cooling capacity and an increase in power consumption.

When a 0.1mm thick oil layer accumulates on the surface area of the condenser, the cooling capacity of the water cycle refrigerator compressor will decrease by 16.6 and the power consumption will increase by 12.4. When the oil is an inner surface evaporator with a thickness of 0.1 millimeters, in order to maintain the predetermined low temperature requirement, the evaporation temperature decreases by 2.5 ° C and the power consumption increases by 9.7.
