The absorption pressure of the absorber can be increased to improve the absorption rate of the solution, but the traditional absorber uses various heat exchange devices to exchange heat and absorb, so that the absorption pressure cannot be improved, if lower refrigeration temperature needs to be obtained, the pressure of the evaporator must be reduced, and the traditional heat exchanger absorber cannot reduce the pressure of the evaporator, so that correspondingly lower refrigeration temperature is obtained. In the prior art, the ejector is adopted for absorbing, but a mode of absorbing firstly and then cooling is often adopted, and the solution in the ejector cannot be cooled effectively in time, so that the absorption rate is influenced; further, the absorption device emits a large amount of heat during absorption, and cooling water is generally used for removing the heat, but the absorption heat cannot be recovered, and a large amount of cooling water is consumed; in addition, as the absorption pressure of the absorber is generally lower than the cooling water pressure, once the heat exchanger type absorber leaks, the cooling water easily enters the refrigeration working medium solution, and particularly the influence on the non-aqueous refrigeration working medium solution is great. We have therefore proposed a dual-tower refrigeration system and method of operation thereof to address the above-mentioned problems.
