The lights in the warehouse are not on. Please check whether the switch fails and whether the bulb is damaged. Cut off the power supply when installing the lampshade， and pay attention to the waterproof of the lamp.
Indirect cooling is that the air in the warehouse is pumped into the air cooling device by the blower. The air is absorbed by the evaporation pipe circling in the cooling device，Cold storage construction and productionPrinciple characteristics and application fields of and then sent to the warehouse for cooling. The advantages of air cooling are rapid cooling，Special cold storage for slaughterhouse uniform temperature in the warehouse， and can bring harmful gases such as carbon oxide out of the warehouse during storage.
AeAfter years of service，Cold storage installation - cold storage installation - cold storage construction - fruit preservation cold storage medicine cold storage - Anhui Fuyang Xinyuan Refrigeration Technology Engineering Co., Ltd the refrigeration oil inside the compressor should be replaced. The oil， copper，Cold storage construction and productionPrinciple characteristics and application fields of iron and impurities caused by wear are mixed in the refrigeration system，Special cold storage for slaughterhouse which thickens the refrigeration oil，Special cold storage for slaughterhouse deteriorates the fluidity and performance reduces the effect， takes a long time， and the current will increase relatively compared with the new machine， which is a bad phenomenon.
tThe cold storage board uses light polyurethane as the inner material of the cold storage board. The advantage of polyurethane is that the thermal insulation performance is very good. The exterior of polyurethane cold storage board is composed of SII， PVC color steel plate and stainless steel plate. The advantage of this is to prevent the temperature transmission of cold storage board due to large internal and external temperature difference， so as to make the cold storage more energy-saving and improve the working efficiency of cold storage.
Cold storage design and installationOperation specification
Actual factors affecting the increase of exhaust temperature of fresh-keeping warehouse: low intermediate cooling efficiency or too much scale in the intercooler of fresh-keeping warehouse affects heat exchange， the suction temperature of the later stage must be high， and the exhaust temperature will also increase.
The refrigerant charge is insufficient. At this time， good permeability to water vapor， foam holes， disconnected and closed porosity of more than %. It is a dense microporous foam material， which is more dense than air surface， and is not easy to permeate. It belongs to hydrophobic materials.
