1983年,苏联开始生产现代化的BP18×2-1-2型加热制冷机。 BP18×2-1-2型加热制冷机的符号:BP18×2表示该加热制冷机用于在冷藏车货问内冷却空气和保持既定的温度工况并配备有在蒸发温度t_o=-15℃和冷凝温度t_K=30℃时产冷量为21kW(18000kcal/h)的两台压缩机; 1-使用制冷剂R12;2-用于普通温度范围内无产冷量调节。根据所进行的工作,制冷机产冷量有所增加,机器重量和所需功率得以减少,延长
In 1983, the Soviet Union began production of a modern BP18 × 2-1-2 heating chiller. BP18 × 2-1-2-type heating chiller symbol: BP18 × 2 that the heating chiller is used to cool the air in the refrigerated goods delivery and maintain a predetermined temperature conditions and is equipped with the evaporation temperature t_o = -15 ℃ And two compressors with a condensing temperature t_K = 30 ° C and a capacity of 21 kW (18000 kcal / h); 1- Refrigerant R12 used; 2- No adjustment of the cooling capacity in the normal temperature range. Depending on the work performed, the capacity of the chiller increased, the weight and required power of the chiller reduced and the lengthening
