The falling film spray type chiller is a new generation of environmentally friendly chiller developed by our company based on years of design and manufacturing of chiller units, extensive collection of market demand, adhering to the concept of "high efficiency, energy saving, environmental protection, and low-carbon", and absorbing the advantages of similar products at home and abroad.

When the process conditions are met, the falling film chiller product has relatively high heat transfer efficiency, and has advantages such as low refrigerant filling and excellent oil return performance.

Select a specialized falling film semi closed screw refrigeration compressor from an internationally renowned brand, with a high-efficiency 5:6 third-generation asymmetric toothed screw.

Adopting a falling film spray evaporator, the refrigerant is sprayed downwards from the top of the heat exchange tube array, and only a layer of liquid refrigerant film is covered on the surface of the heat exchange tube, resulting in excellent heat transfer effect. The electronic expansion valve is used as a throttling device for refrigerant to the evaporator, and the refrigerant circulation injection pump is used to extract and recycle the liquid refrigerant at the bottom of the evaporator. The refrigerant filling amount is relatively low, which meets environmental requirements.

Shell and tube condenser, optimized temperature field distribution and refrigerant flow field distribution, high heat transfer efficiency.

An advanced and reliable control system that tracks and adjusts the energy output of the unit in real-time based on changes in user compliance and environmental parameters, ensuring that the unit operates at its highest efficiency point and maximizes cost savings for users.

The design of dual compressors for large cooling units further improves the reliability of unit operation.

A reliable oil management system with three levels of oil return: oil separation return oil, evaporator suction return oil, and evaporator injection return oil, ensuring reliable oil return for the compressor.

The injection pump completes the low-pressure side oil return function, and the electronic expansion valve ensures precise supply of refrigerant flow under any suitable condition. Reliable and comprehensive testing, convenient transportation, installation, and debugging, high-voltage unit.

The use of a high-voltage dedicated compressor ensures reliable oil return and supply at any load, while reducing the power consumption and leakage of the oil pump.

It has the characteristics of safety, reliability, high efficiency, energy saving, and environmental protection, with a wide range of applications. At the same time, it can also be used as a cold source host for various industrial processes, providing high-quality 4-12 ℃ refrigeration air conditioning environment for its air conditioning use or process. Low temperature series effluent conditions can also be customized according to requirements.
