Abstract

The present invention is a plate heat exchanger that allows refrigerant to enter the heat exchanger simultaneously from two sides. Allowing the refrigerant or other fluid to enter from two sides splits the flow and improves fluid velocities by presenting an optimized area to the fluid flow. This effect may be realized for both gases and liquids, and for example with respect to a liquid refrigerant, where it enters the heat exchanger simultaneously by splitting. According to the present invention the split liquid flow from the condenser feeds dual electronically controlled expansion valves before entering the heat exchanger. Fully evaporated gas leaves the heat exchanger through a single outlet, or through a dual outlet.
