Jiangsu DD100 square refrigerator factory direct cold air cooler chiller

D series air cooler Features: D series air cooler is a cooling device supporting the compartment cooling units use Freon refrigerants, as applicable temperature sub-divided into DL, DD, DJ, three series, can be separately applied Different storage temperature, DL type air cooler is mainly applied to the preservation of about 0 ℃, DD type air cooler is mainly applied to -18 ℃ refrigerator, DJ type cooling fan is mainly applied to -25 ℃ or less frozen library. This series has the following characteristics: Designed for fresh, chilled, frozen and design; shell is made of high quality steel, powder coated, corrosion resistance, appearance; coil using Staggered way, using a mechanical expansion tube, so that the brass??? closely integrated with the aluminum, good heat transfer effect;? high-quality stainless steel electric heating tube evenly distributed in the coils. Good defrost effect; defrost using electric heating tube aluminum fin hole casing and close, easy to heat, long life;? Chillers designed width, blades and aluminum fin spacing is greater than 1/3 the diameter of the blades ensure There are enough effective air flow; can use long-range air duct according to customer requirements; standard chiller technical parameters:? t apply to library = -25 ℃, △ t = 10 ℃, for R134a energy correction factor is multiplied by f, QOR134a = QOR22 * f DD-4.1 / 22-type chiller its cooling capacity is 4070 watts nominal cooling area is 22 square meters, the reservoir capacity 1.4 kg, the refrigerant inlet / outlet pipe is Φ12 / Φ25 mm, which blower air volume 5100 cubic meters per hour, the number is 3N, fan diameter 300 mm, voltage 380/220 V, power is 3 * 75/3 * 90 watt, has a range of 8 meters, its electric defrost the fins defrosting power 2400 watts, water tray power is 1200 watts. DD-5.6 / 30-type chiller its cooling capacity is 5920 watts nominal cooling area is 30 square meters, the reservoir capacity 2.2 kg, the refrigerant inlet / outlet pipe is Φ16 / Φ32 mm, air volume fan of 6000 cubic meters per hour, the number is 2N, fan diameter 400 mm, voltage 380/220 volts, power is 2 * 180/2 * 250 watts, has a range of 10 meters, its electric defrost the fins defrost power is 2600 watts, then water tray power is 1300 watts.
