1. Adjustment and timely defrosting of the evaporator Generally speaking, every 1°C increase in the evaporation temperature of the cold storage can save 2%~2.5% of energy. Therefore, on the premise that the product refrigeration process can be met, the evaporation temperature can be increased as much as possible by adjusting the liquid supply. Second, choose the cold storage door with good sealing performance. If the sealing performance of the cold storage door is not good, it will also cause power consumption and energy consumption, so you need to be careful when choosing the cold storage door. The picture below is the high-quality cold storage door developed by our company. 3. Use the temperature difference between day and night to operate my country has a vast territory, and many areas have a large temperature difference between day and night. Usually, the temperature difference between day and night in the oceanic climate area is 6~10℃, and the continental climate

1. Adjustment and timely defrosting of the evaporator

Generally speaking, every 1°C increase in the evaporation temperature of the cold storage can save 2% to 2.5% of energy. Therefore, on the premise that the product refrigeration process can be met, the evaporation temperature can be increased as much as possible by adjusting the liquid supply.

Second, choose the cold storage door with good sealing performance

If the sealing performance of the cold storage door is not good, it will also consume electricity and energy, so you need to be careful when choosing the cold storage door. The picture below is the high-quality cold storage door developed by our company.

3. Use the temperature difference between day and night to operate

my country has a vast territory, and many areas have large temperature differences between day and night. Usually, the temperature difference between day and night in the oceanic climate area is 6~10℃, and the temperature difference between day and night in the continental climate area can reach 10~15℃. The ambient temperature at night is low, and the boot time at night can be adjusted and extended according to the storage characteristics of the product. Since the condensation temperature is relatively low, it is beneficial to the energy saving of the cold storage.

Fourth, improve the utilization rate of the warehouse, save energy and reduce consumption

The power consumption of the refrigerated room is calculated according to the amount of cooling consumption of the refrigerated room. The key to saving electricity is the utilization rate of the refrigerated room. It is recommended to customize reasonable shelves in the cold room to improve the utilization rate. The goods in each refrigerated room are combined in time according to the storage temperature to reduce energy consumption.

5. Energy-saving lighting system in cold storage

The cold storage lighting selects LED lamps that are environmentally friendly, energy-saving, uniform in illumination, good in luminous efficiency at low temperature, and high in power supply efficiency. In addition, turn off the lights in time to reduce the heat load and power consumption of the warehouse.

6. Regularly drain oil, descale and exhaust air to ensure good heat exchange effect

Studies have shown that when there is a 0.1mm thick oil film in the evaporator coil, in order to maintain the set temperature requirement, the evaporation temperature will drop by 2.5℃, and the power consumption will increase by more than 10%; when the water pipe wall in the condenser is scaled When it reaches 1.5mm, the condensing temperature will increase by 2.8°C compared with the original temperature, and the power consumption will increase by 9.7%; when the non-condensable gas is mixed in the refrigeration system and its partial pressure value reaches 0.196mpa, the power consumption will increase by about 18%. %. This shows the importance of regular oil discharge, descaling and air discharge in the refrigeration system of the cold storage.

7. Select the mechanical polyurethane cold storage board with stable thermal insulation performance

The continuous line high flame retardant PU and PIR boards produced by Yanghu Company are produced by fully automatic assembly line equipment from shearing, hemming, beading, and shaping. The accuracy is higher and the thermal insulation performance is more stable. Many customers have reported that for a refrigerator of the same size, choosing an air-cooled storage board can save energy and electricity by about 30%.
