Abstract:
In an operation method for performing a cooling and heating operation based on rectification, condensing, evaporation and absorption operations of a refrigerant in a system including a generator for boiling a rich solution therein, a solution heat exchanging unit, analyzer and a rectifier installed above the generator, a water cooling absorber communicating with the rectifier, and a radiator communicating with the water cooling absorber, an operation method of an absorption heat pump, comprising the steps of:a step for measuring a temperature of the refrigerant vapor passed through the above-described rectification process; a step for comparing the measured temperature and a previously set temperature and estimating a refrigerant density passed through the rectification process; and a step for controlling a heat exchange amount between a rich solution and the refrigerant vapor during the rectification process based on the estimated refrigerant density.
