The failure of refrigeration system in small cold storage

Small cold storage, including movable cold storage, generally have a capacity of less than 100 tons. The cold storage evaporator adopts a platoon type or a combined type of air cooler, and a

Cold storage anti-corrosion and anti-frost coatings effectively solve the problem of frosting and corrosion

In the cold storage, when the dew point of the air is lowered by the cooling pipe surface, the moisture in the food and air will precipitate and condense on the pipe wall. If the pipe wall temperature is lower than 0°C, it will condense into a rain layer.

What are the common faults of air conditioning compressor repair

Presumably everyone is also curious about the cooling effect of the air conditioner. In fact, all this is the credit of the compressor. The principle is that the compressor extracts the refrigerant from the low-pressure area, compresses it, and sends it t器2䀀

Compressor protection measures against liquid strikes

Compressor protection measures against liquid strikes When too much liquid enters the cylinder and it is too late to discharge it from the exhaust valve, a liquid blow will occur in the cylinder. The high pressure generated during the liquid blow damages the cylinder, piston, connecting rod, etc., so it is necessary to take a Series of protective measures.
