In the two-stage compression refrigeration cycle, the compression process of the refrigerant is performed in two stages, the low-pressure refrigerant vapor (pressure p0) from the evaporator is first introduced into the low-pressure compressor where it is compressed to the intermediate pressure pm and after intermediate cooling And then into the high-pressure compressor, its compression to the condensing pressure pk, discharged into the condenser. In this way, the pressure ratio can be moderate at all levels, because after the intermediate cooling, but also to reduce the work of the compressor work, reliability, economy have improved.
When the evaporation temperature is low, the use of two-stage compression refrigeration cycle can achieve the following purposes:
Reduce the pressure ratio, to avoid and reduce the loss caused by high pressure ratio
Such as reducing the exhaust temperature of the compressor to improve the actual air volume, the refrigerator running balance improved.
The traditional air conditioning can only be the lowest at minus 7 degrees Celsius in the environment to achieve heating, and the use of two-stage inverter compressor dual-stage inverter air conditioner can be achieved at minus 30 ℃ under extreme conditions of heating, 54 ℃ high temperature The rapid cooling in the environment, the winter heating capacity increased by 40% or more, the summer cooling capacity increased by 35% or more, and the minimum power of only 15 watts to solve the low-temperature heating and high temperature refrigeration effect of the problem, to expand the use of regional air conditioning blue ocean, The use of air conditioning temperature of the new record.

Two-stage frequency conversion, as the name suggests refers to the evaporator from the refrigerant vapor to go through low-pressure and high-pressure compressor (or cylinder) twice compressed before entering the condenser. It is with the single-stage compression refrigeration cycle flow of the main difference is that most of the refrigerant must be in the high and low pressure level two cylinder compression, the general also added the intercooler and expansion valve.
