Spray Type Water Cooling Unit Evaporator Falling film Evaporator

Spray Type Water Cooling Unit Evaporator

Falling film Evaporator

This product is a new type of high efficiency heat exchanger, which uses the spray device to spray the

liquid refrigerant on the surface of the heat exchanger and evaporate, greatly improve the evaporator

heat transfer efficiency; the same time, it avoids full liquid evaporation The need to charge a large number

of refrigerant shortcomings, reduce the use of central air conditioning costs, more conducive to the

compressor oil.

The liquid refrigerant after the throttle depressurization enters the refrigerant distributor through the

refrigerant inlet, the refrigerant distributor uniformly sprays the liquid refrigerant on the heat transfer tube

bundle, the liquid refrigerant flows downward due to the action of gravity and forms a layer under the heat

transfer tube Liquid film, liquid film in the heat transfer tube to absorb the heat of chilled water after the

evaporation of gas, heat transfer tube frozen water due to loss of heat and was cooled.

1. Refrigerant in the heat transfer tube to achieve thin film evaporation, heat transfer temperature

difference is small, high heat transfer coefficient.

2. Refrigerant charge less, you can save costs, more environmentally friendly.

3. After the refrigerant evaporates back to the compressor, the frozen oil will flow down and accumulate at

the bottom of the evaporator, and the oil return is more convenient.
