How to solve the low service life of vertical refrigerated display cabinet? This is always the main problem that puzzles users. Refrigerated display cabinet has always been loved by the majority of businesses, but its service life is not high has been the main problem that plagues users. So how to improve the service life of refrigerated cabinets? Let's learn about the maintenance methods of high refrigerated display cabinets.
Maintenance method of vertical refrigerated display cabinet
1. Before using the refrigerated display cabinet, read the instructions in detail. The newly purchased or handled refrigerated display cabinet shall be kept for 2 to 6 hours before it is started to avoid oil circuit failure. Before use, the first line 2 to 6 small time-space boxes are electrified for operation. If the refrigeration effect is good, the food can be stored. In case of accident, the compressor can not be started immediately after shutdown, and it needs to wait for more than 5 minutes to avoid burning the compressor.
2. The power supply of refrigerated display cabinet must be provided by special line, and the socket shall be reliably grounded. When the power supply voltage fluctuates greatly, a voltage regulator with more than 5 times the power of the whole machine shall be installed.
3. Proper space shall be reserved between the stored foods to keep the air-conditioner circulating. Hot food should be cooled to room temperature before putting in, so as not to stop for a long time. The food should be sealed with fresh-keeping bags or paper or put into sealed containers to prevent the food from getting damp, losing water and stringing. The food with water should be put in after removing the water so as not to form too much frost due to the evaporation of a large amount of water.
4. When using refrigerated display cabinets, the number of opening doors shall be minimized to prevent loss of cooling capacity.
5. If the refrigerated display cabinet is not used for a long time, the power supply shall be cut off to keep the cabinet clean and dry.
6. The refrigerated and frozen display cabinet shall be placed away from the heat source, well ventilated, solid and flat, so as to prevent the high ambient temperature from causing the poor heat dissipation of the condenser and affecting the refrigeration effect.
7. The condenser shall be cleaned once every three months. During cleaning, the power supply shall be cut off, and then compressed air shall be used for purging. When there is much dust on the surface of the condenser, clean it thoroughly with clean water. When flushing with clean water, pay attention to avoid wetting other electrical components.
