Ⅰ. Brief Introduction

Falling film evaporator is that the refrigerant is evenly distributed to the surface of the heat exchange tube through the liquid separator designed at the top, forming a film-like evaporation and efficient exchange heat with the medium in the tube.

Ⅱ. Product Details

The falling film evaporator developed in the early 1990s is gradually replacing the traditional Shell and tube Evaporator. The falling film evaporator has good economic benefits due to the low refrigerant charge, high energy efficiency, low power consumption, energy saving and consumption reduction characteristics. At the same time, it has great potential in environmental protection and has achieved good energy efficiency and emission reduction goals. At present, the centrifuge unit and high-pump heat pump technology are developing rapidly. For example, a large amount of refrigerant can be saved after using a falling film evaporator, which can improve the energy efficiency of the unit and reduce operating costs.

Ⅳ. Advantages, Features and Application

1. Selection of high-efficiency spray type heat exchange tubes, liquid separation won the national utility model patent.

2. It has good oil return, can effectively avoid the risk of compressor suction and liquid and reduce maintenance costs.

3. The heat transfer coefficient is about 20% higher than the flooded evaporator, and the refrigerant charge is reduced by more than 30%. Improve the energy efficiency of the unit and reduce the cost of the whole machine.

4. Adapt to compressors such as screw, centrifugal and magnetic suspension.

Ⅴ. Company Service

WIELAND and the HTRI are used to calculate the heat transfer performance of the Shell and Tube Heat Exchanger, and the heat transfer performance test is performed on the product based on the H.Stars Group's independent test platform. The product strength calculation uses SW6-2011v4.0 software in the pressure vessel industry to calculate its strength, and has passed the inspection by the Guangzhou Municipal Quality and Technical Supervision Bureau. The company has passed ISO9001 quality management system certification, ISO14001 environmental management system certification, and obtained pressure vessel design license and D-level pressure vessel manufacturing license. Over 20 years of technical accumulation has accumulated rich design experience to keep our products continuously leading.

Ⅵ. Product Maintenance

1. When the product is stopped in winter or cold season, the water in the heat exchanger should be drained to prevent the copper tube from being frozen and cracked.

2. Products should be cleaned regularly. Remove the dirt in the heat exchange tube to improve the heat transfer efficiency.

Ⅶ. FAQ

1. Should the heat exchanger be cleaned regularly?

Answer: It should be cleaned regularly. Because the heat exchanger runs for a period of time, a layer of dirt will adhere to the inner wall of the heat exchange tube, which will affect the heat transfer efficiency of the heat exchange tube.
