Flue gas absorption refrigeration unit

This kind of chiller mainly composed of high temperature generator, low temperature generator, condenser, evaporator, absorber, high temperature heat exchanger and low temperature heat exchanger.

Unit parameters

Flue gas absorption refrigeration unit

Note:

The fouling of chilled water is 0.086㎡ ℃ / kW.

working principle

Lithium bromide water absorption refrigeration device is mainly composed of generator, condenser, evaporator and absorber. Its basic working principle is as follows:

(1) The working heat source (such as steam, hot water and gas) is used to heat the dilute solution delivered from the absorber by the solution pump in the generator, and the water in the solution was evaporated to be steam.

(2) The steam enters the condenser and was condensed into refrigerant water by the cooling medium.

(3) The refrigerant water enters the evaporator by throttling, absorbs the heat of refrigerant water and becomes steam.

(4) In the generator, the remaining concentrated solution enters into the absorber, mixes with the water vapor from the evaporator, absorbs the steam and returns to the original concentration and becomes a dilute solution. The dilute solution enters the generator again through the solution 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.
