[Durability Improved by the Structure Preventing Rupture of Heat Pipe]
This product was scientifically designed to prevent resonance, thereby preventing the heat pipe from rupturing due to the resonance of the pipe generated during the rapid heat exchange in the high temperature generator. Therefore, the durability of the chiller is improved.
[High Efficiency Drain Heat Recovery System]
Trap and drain heat exchanger was installed to discharge only condensate water except the steam at the high temperature generator drain. Thus, the temperature of the condensate water drain drops to below 95℃ and drain heat recovery is improved to maximize the efficiency of the chiller.
[Cooling Cycle of High Efficient Double Effect Steam Fired Absorption Chiller]
The body of the chiller is composed of evaporator, the lower part of the absorber, condenser, the upper part of the low temperature generator, high temperature generator, high temperature heat exchanger, low temperature heat exchanger, solution (weak/thick), refrigerant pump, steam trap, and heat recovering device.
The evaporator cools the cold water and the evaporated refrigerant is absorbed by the absorbent (thick solution) within the absorber and the absorbent becomes weak solution.
Now the solution pump makes the solution flow through the low temperature heat exchanger and the high temperature heat exchanger, become heated and flow into the high temperature generator. There, the solution is heated by high temperature and high-pressure steam and becomes condensed to the medium concentration.
This solution of medium concentration then travels through the high temperature heat exchanger and then moves to the low temperature generator, becomes thick by the refrigerant steam generated from the high temperature generator. And then, this thick solution flows through the low temperature heat exchanger and comes back to the absorber in low temperature and repeats the process of absorption.
During this process, the steam supplied to the high temperature generator heats the solution in the generator and travels through the steam trap at the end of the drain and through the drain heat recovering device that is installed for the heat exchange with the absorbent and lowers the temperature of the steam condensate water down to below 95℃ and discharges. Therefore, heat recovery of the drain is improved, thereby enhancing the efficiency of the chiller as well.
