Optimize structural design to raise heat efficiency

1 Adopt new heat exchange tube to strengthen heat transfer and quality transfer affect. Comprehensive heat exchange co-efficient rises by 15%

2 High temperature generator cooling stat generation technology,temperature and concentration down

3 Adopt new counter flow side flow heat exchange in heat exchanger

4 Vacuum heat insulation layer in upper shell reduces internal heat loss

5 Internal refrigerant self-adjusting cooling storage device

Internal refrigerant self-adjusting cooling storage device

Main effect: it may realize load self-adjusting ,cooling storage, shorten start and dilution operation time of the machine, suit much lower cooling water inlet temperature, reduce heat loss in evaporator and prevent cavitation erosion of refrigerant pump.

Quick start , short shutdown time energy saving

Adopt internal self-adjusting cooling saving device, new frequency conversion technology, high temperature generator cooling state generation technology and continuous control of fuel control valve, save start and shutdown energy: saves 40% at start, saves 33% at shutdown.

Four Crystallization Prevention Safety Control

The micro-computer monitors the temperature and concentration of the solution and adjusts solution flow rate and fuel volume, which make solution circulation far from crystallization zone. The crystallization is prevented completely.

High temperature generator cooling stat generation technology: temperature 154°C, concentration 61~62%

Auto-decrystallization technology
