Description
Technical field
The present invention relates to the distribution method technical field of a kind of refrigerator and its flow, more particularly to a kind of double systems in parallel
The distribution method of system refrigerator flow.
Background technology
Generally, we do not use complete system in parallel as the preferred scheme of refrigerator refrigeration system, because
In the case of the parallel connection completely of single compressor, two branch roads, due to two branch road inlet and outlet pressures changes, refrigerant air-liquid two-phase is not
Stability, such system easily forms the distribution of some branch road refrigerant excessively, and the distribution of another branch road refrigerant is very few
Situation, in process of refrigerastion refrigerant distribution also have uncertainty.It has impact on refrigeration, in fact it could happen that in the stipulated time
Inside it is unable to reach cooling to require, the efficiency of compressor is also accordingly reduced.But the mode of series connection is taken, can not but meet two is
The requirement that system is independent of each other.
But if requiring that two compartments realize wide alternating temperature, warm area from be chilled to refrigeration can be separately adjustable, such ice
Case requires that two compartments can not influence each other, so two systems must be separate, it is therefore desirable to provide a kind of double systems in parallel
