working principle

When the unit is working, the light solution in the absorber is transported to the high temperature heat exchanger and the low temperature heat exchanger by the generating pump in two ways, and then enters the high temperature generator and the low temperature generator respectively after heat exchange and temperature rise.

When the dilute solution entering the high-temperature generator was heated to the evaporate point by the working steam, the high-temperature refrigerant steam is generated, which is go into the low-pressure generator to heat the dilute solution in the low-temperature generator, and then enters the condenser through throttling, finally  cooled into refrigerant water. The refrigerant water produced by the high and low pressure generators is combined by the condenser water collector and then led into the evaporator.

The refrigerant water absorbs the heat of the refrigerant water in the evaporator and intensifies into water vapor. In the high and low pressure generators, the heavy solution enters the absorber and mixes with the water vapor from the evaporator. The water vapor is absorbed and recovered to the original concentration and becomes dilute solution. The dilute solution enters into the high and low pressure generator through the generator pump and continues to circulate.

Product advantages

1、The unit uses waste heat and waste heat for refrigeration,almost no energy is needed.Operation cost is very low;

2、Each chamber inside the unit is designed with vacuum insulation layer to reduce internal heat loss and improve unit efficiency;

3、The COP of low temperature hot water absorption lithium bromide refrigeration unit and 0.1MPa steam type absorption lithium bromide refrigeration unit is above 0.72;

4、The COP of vapor type (0.6 MPa, 0.8 MPa) absorption lithium bromide chiller is above 1.35;

5、The COP of direct fired absorption lithium bromide chiller is above 1.35;

6、Leak detection for five consecutive processes to ensure that the unit has no fault due to leakage;

7、High intelligent automatic control. The unit can be started up and shut down by "one key", with the function of fault alarm dilution and shutdown.

8、The control system directly or indirectly controls the cooling water pump, cooling water pump and cooling tower fan, which improves the overall efficiency of solar air conditioning system by 25%;

9、The color LCD touch screen is used in the computer automatic control, which can dynamically display the operating conditions of the unit. The screen has the function of fault recording and real-time recording of parameter operation curve.

10、The first-line brand control components are adopted: Omron CP1 series PLC, OmronLY2N-Jseries relay, Schneider IC65series circuit breaker, Schneider LC1-Dseries contactor, WEINVIEWtouch screen, WILO water pump of Germany. These components ensure the reliability of the control system hardware.

11、Fine workmanship ensures the service life of the unit is 23 years and 30 years.
