EVI compressor, super forced heating, high efficiency and stability
EVI technology refers to the optimization of the medium pressure refrigerant injection technology based on the EVI compressor. The principle is to suck a part of the intermediate pressure gas through the intermediate pressure suction hole (Vapour Injection), mix it with the partially compressed refrigerant and then compress it to achieve two-stage compression with a single compressor, which increases the refrigerant flow in the condenser. The enthalpy difference of the main circulation loop is increased, thereby greatly improving the efficiency of the compressor.
High-efficiency finned heat exchanger
The use of a new type of high-efficiency CTIG (cross-tooth internal thread) copper tube, with a groove design on the inner surface, has a larger contact area with the refrigerant, and has a better heat exchange effect.
High-efficiency shell and tube heat exchanger
Spiral baffled shell and tube heat exchanger is used to improve the heat transfer coefficient. Equipped with high-efficiency "U-shaped" copper tubes, the refrigerant can be continuously evaporated, and the heat exchange efficiency is increased by 10%.
High-efficiency two-speed regulating motor, combined with new high-torque fan blades
The spiral airflow fan is designed with high torque and CFD performance at low speed, and the tip of the blade is bent to suppress the blade tip vortex, achieve excellent low operation and obtain more air volume, ensure good heat exchange effect, and improve the efficiency of the whole unit.
High-precision electronic expansion valve, excellent throttling performance
Using electronic expansion valve throttling with an adjustment range of up to 500 steps, the opening degree of the electronic expansion valve can be flexibly adjusted according to different operating modes and temperature conditions, which significantly enhances the adaptability and stability of the unit in complex operating environments under various modes.
