The K/V evaporator - a design and the principle of functioning

Principle of functioning of the evaporator

1 — From a receiver dehumidifier
2 — To the compressor
3 — a suspension of particles of coolant, Close to a liquid state

4 — Steam
5 — the Broad valve


The air forced by the heater fan is banished through the heat exchanger of the evaporator and promotes heating of the liquid coolant moving on tubes, being under low pressure. Having reached a boiling point, coolant starts evaporating intensively, passing into a gaseous state. The moisture containing in coolant is condensed in drops and together with particles of dirt is taken away from system on a special drainage hose.

The heat exchanger of the evaporator is a set of the squared thin aluminum plates located in some layers with the lamels fixed between them.

The suspension of particles of coolant which is in close to liquid a state via the broad valve under low pressure comes to the lower tube of the evaporator and starts being warmed intensively. In view of high intensity of heat exchange coolant quickly reaches a boiling point and evaporates. Further, at the expense of developed by the bubbles of carrying power generated during boiling, coolant rises and gets into the assembly tube located above. By the time of hit in the top tank of the evaporator coolant completely passes into a gaseous state.

The design of the evaporator differs in the high durability of execution, resistance to impact of corrosion and thermal stability.
