What is the problem of high liquefaction efficiency?

It has been snowing heavily these days, the road is blocked, there is no raw material, the electrolysis current is low, the load is low, and the total amount of chlorine delivered is less than normal. The energy level of the unit is 25%, unit R2 2. The liquid level is not easy to control. The suction pressure is 0.9, the suction temperature is -19 degrees, and the normal temperature is -23 degrees. The liquefaction efficiency is 90-97%, and the hydrogen content of the exhaust gas is 0.47. The previous liquefaction efficiency was 80-90%, and the hydrogen content of waste chlorine was 0.2--0.27. The liquefaction efficiency is high, but the hydrogen content in the exhaust gas cannot be adjusted down. The person who uses the same unit as us has encountered this problem? What should I do? #,, &
The cold medium flow rate of the chlorine condenser can be appropriately reduced and the temperature of the condenser can be increased. At the same time, the temperature of the F22 evaporator can be appropriately increased to reduce the temperature and pressure.
The pressure difference between the original chlorine and the tail chlorine should be properly controlled. However, according to production experience, the energy of Dalian's liquefaction refrigeration unit can be adjusted under normal circumstances. :lol
Screw machines have adjustment slide valves. Can your capacity adjustment device be used?
