The use of cold storage in summer is high, and the equipment in the refrigeration system is in high-load operation. If the cold storage is not used for maintenance, the cold storage is more prone to failure.
1, the outdoor temperature in summer is high, and the convection is intense. Therefore, the switching of the cold storage door should be minimized. When using the cold storage, pay special attention to the operators in the cold storage must be trained and certified. Otherwise, the loss of refrigeration equipment will be aggravated due to frequent improper operation, and the service life of the machine will be reduced, which may cause safety accidents.
2, the storage in the cold storage must be placed in accordance with the specified discharge conditions, can not be greedy and stacked storage, accumulation and storage is likely to cause storage products to shrink the shelf life, water temperature is a major guarantee for the operation of cold storage in summer, cooling water for cold storage water cooling unit The water intake should preferably not exceed 25 °C. When the temperature exceeds 25 °C, tap water should be replenished in time, and the circulating water should be replaced frequently to keep the water clean. Regularly check the radiator of the air-cooled unit and clean the dust on the radiator in time to avoid affecting the heat dissipation effect.
3, regularly check the wires and various electrical accessories of the cold storage control system. Don't forget to check if the water flow of the cooling water pump is normal, and whether the cooling fan's fan is rotating forward. The criterion is whether the hot air is rising. Cold storage refrigeration equipment does not stop working within 24 hours a day, machine maintenance work is also a top priority, regular need to add lubricant to the unit, regularly check the operation of the equipment, once found damaged must be repaired, replaced immediately, must not hug There is luck.
4, try to reduce the switching frequency of the cold storage door. Because of the high outdoor temperature in summer and the strong convection between cold and heat, on the one hand, it is easy to cause a large amount of cold inside the cold storage, and on the other hand, it is easy to cause a large amount of condensation inside the cold storage. Check the ventilation environment of the air-cooled unit to ensure that the hot air discharged from the unit can be released in time. When the ambient temperature is too high, water can be sprayed on the fins of the radiator to help dissipate heat and improve the cooling effect.
5, strictly control the inventory, so as to avoid the refrigeration unit to work for a long time, the storage temperature drops slowly.
6. Pay attention to providing sufficient outdoor air to the outdoor unit. The hot air discharged from the condensing unit should be away from the outdoor unit and the hot gas circulation cannot be formed.
