Evaporator Flow Principle

The channels formed between the corrugated plates and corners are arranged so that the two media flow

through alternate channels, always in opposite directions (counter current flow). The two phase refrigerant

(vapor + liquid) enters the bottom left of the exchanger with a vapor quality depending on the operating

condition of the plant. Evaporation of the liquid phase takes place inside the channels and some degrees of

superheat are always requested, which is the reason why the process is called "dry expansion". In the enclosed

evaporator picture the dark and light blue arrows show the location of the refrigerant connections. The water

(brine) to be cooled flows counter current in the opposite channel; the dark and light red arrows show the

location of the water (brine) connections.

Standard Design

The plate pack is covered by cover plates. Connections are located in the front or rear cover plate. The channel

plates are corrugated to improve heat transfer efficiency and to make them rigid.

Dual System

The real dual circuit patented by Baode in a solution with diagonal flow is obtained by means of pressed plates. The Brazed Plate Heat Exchanger can be connected with two independent refrigerant circuits. The special design ensures that each refrigerant circuit is in contact with the entire water flow. The main advantage is that at partial load (only one compressor running) water cooling is uniform and performance is maximized.
