A refrigerant distribution system has a plurality of chambers formed inside a refrigerant distribution plate, each of the plurality of chambers extending from one end of the refrigerant distribution plate into the refrigerant distribution plate; and a plurality of holes formed in each of the plurality of chambers, the plurality of holes fluidly communicating each of the plurality of chambers with an outside of the refrigerant distribution place. The evaporator may be oriented such that the refrigerant flows horizontally with respect to gravity. The present invention may improve the thermal performance of the evaporator while the evaporator is oriented sub-optimally. Often, with horizontal flow through an evaporator, the refrigerant phases, liquid and vapor, may separate in the manifold, resulting in poor distribution of refrigerant in the evaporator core. The refrigerant distribution plate of the present invention evenly distributes the refrigerant in the core.
