从1987年起苏联将生产上述新型制冷机和压缩冷凝机组代替将停产的LXM—φYY801、1XM—φYY801Рэ剖冷机和1AK、φYY801,AK-φYY801Рэ压缩冷凝机组。在新的机组中,热交换器采用直径为16×2毫米的外肋钢管代替20×3毫米铜管。该机组可用于冷却水或载冷剂,其出口温度为10到-25℃;蒸发温度为5到-30℃冷,却水温度不超过30℃,载冷剂和冷却水容许压力为0.6兆帕。整套
Since 1987, the Soviet Union will produce LXM-φYY801, 1XM-φYY801ORPOR chillers and 1AK, φYY801, AK-φYY801Рэ compressing and condensing units that will be discontinued instead of the new chillers and condensing units mentioned above. In the new unit, the heat exchanger replaced the 20 × 3 mm copper tube by a 16 × 2 mm diameter external ribbed steel tube. The unit can be used for cooling water or refrigerant, the outlet temperature is 10 to -25 ℃; evaporation temperature is 5 to -30 ℃ cold, but the water temperature does not exceed 30 ℃, coolant and cooling water allowable pressure of 0.6 trillion Pa.
