Abstract
An automatic purger for an absorption heat pump has a generator, a condensor, an evaporator and an absorber. The purger includes an eductor connected to the absorber, a purging chamber connected to the absorber and mounting therein a nozzle, a heat-dissipating tube connected between the educator and the nozzle, a storage tank communicating with the absorber and mounting thereto a solution level controller, a diffuser for increasing the pressure of the absorbing agent solution ejected from the nozzle into the storage tank, and a vacuum pump connected to the storage tank. Due to a low pressure zone formed around the exit of the nozzle in the purging chamber, non-condensable gas existing in the absorber will be extracted into the purging chamber and then be carried into the storage tank by the absorbing agent solution ejected from the nozzle. The vacuum pump will be actuated to begin to purge non-condensable gas when the storage tank reaches a predetermined low solution level, and be deenergized to stop purging when the storage tank reaches a predetermined high solution level.
