Abstract:
1. A method of controlling the concentration of an absorbing fluid in an absorption air-conditioner; the absorption air-condition including a desorber, a condenser, an evaporator and an absorber, and piping interconnecting the desorber, condenser, absorber and evaporator; the method comprising the following steps taken in combination: calculating the concentration of the absorbing fluid solution at an output of the desorber, and comparing the calculated concentration of the absorbing fluid solution to a predetermined critical value; whereby, if the calculated concentration approaches the aforesaid predetermined critical value, the head loss is increased in a duct connecting the desorber to the condenser thereby causing a shut down of condensation in the condenser and an increase of the pressure in the desorber; and the increase in pressure in the desorber causing a shut down of desorption and an increase in the concentration of the absorbing fluid solution; and wherein, the head loss is decreased to restart desorption when the calculated concentration moves away from the predetermined critical value.
