 The combined spray evaporator is a new type of high-efficiency heat exchanger, which uses a spray device to spray liquid refrigerant on the surface of the heat exchange tube and evaporate, greatly improving the heat exchange efficiency of the evaporator; at the same time, it avoids The full-liquid evaporator needs to be filled with a large amount of refrigerant, which reduces the use cost of the central air conditioner and is more conducive to the return of the compressor.

The liquid refrigerant after throttling and depressurization enters the refrigerant distributor through the refrigerant inlet, and the refrigerant distributor uniformly sprays the liquid refrigerant on the heat exchange tube bundle, and the liquid refrigerant flows downward due to the action of gravity and forms a layer outside the heat exchange tube. The liquid film, the liquid film absorbs the heat of the chilled water in the heat exchange tube and evaporates into a gas, and the chilled water in the heat exchange tube is cooled by the loss of heat.

Advantage

1. The refrigerant realizes evaporation of the film outside the heat exchange tube, the heat transfer temperature difference is small, and the heat transfer coefficient is high.

2. The refrigerant charge is small, which can save costs and be more environmentally friendly.

3. After the refrigerant is evaporated, return to the compressor. The frozen oil will flow downward and concentrate at the bottom of the evaporator. It is more convenient to return the oil.

Specification

Double spray evaporator

Note:
1. Nominal parameters are based on working conditions: evaporation temperature Te=5°C, superheat degree Tsuc=5°C, inlet water temperature Ti=12°C, and outlet water temperature To=7°C.
2. The heat exchange amount in the above table is QR22. When R134a medium, the heat exchange rate is QR134a=0.8QR22. When R407c medium, the heat exchange rate is QR407c=0.9QR22.
