Iron drain pipes discharge tube refrigerator cold storage characteristics: 1. calandria freezer operating temperature of -22 ° C ~ -25 ° C, the direct cooling type refrigerator. 2. The discharge tube refrigerator uses: meat store, frozen food. Zhong Yun refrigeration refrigerator has four advantages: 1. Good thermal conductivity: discharge pipe has excellent thermal capacity, the evaporation temperature of the refrigerant and a discharge tube outer surface temperature difference decreases, the evaporation temperature will increase, energy efficiency compressor increases, to reduce energy consumption; special structure: row of tubes and calandria parallel to form a sheet shape to form a plurality of parallel channels, the cooling system work form the flue effect of cold air in the channel, is accelerated sink, convection speed up, so cool speed reaches the set temperature of the compressor is stopped, save a lot of energy; set, high efficiency: the projected area and evaporation area than the exhaust pipe can be done one to three or one to four, it has a certain storage effect, Compressor frequent start work rate decreases, save some energy consumption. 2. Dry consume less food: calandria lifting on the top or side of the library, the formation of direct cooling natural convection heat transfer, so that the cooled dry food consumption dropped to a minimum, the compressor reduced working hours, long downtime, so use row Compared with conventional fan made cold cold pipe production, less consumption of dry food, better food preservation effect ,, so that the library moderate humidity, temperature stability, good temperature and humidity effects. 3. The high pressure discharge tube: die cast structure, improved mutual strength, pressure has greatly improved, have been 2.5MP airtight test factory, do 4.5MP voltage life test, intact, the pressure is far below the theoretical data. 4. System Clean prolong compressor life: the inner tube through a special treatment, to ensure clean exhaust pipe interior surface through a special process, long life, but in line with food hygiene standards.
