摘要： An absorption refrigeration system uses a solution and a refrigerant contained in the solution as working mediums. The system includes (a) a generator for heating the solution to change a portion of the refrigerant into vapor; (b) a condenser communicated with the generator, for condensing refrigerant vapor coming from the generator; (c) a throttling device communicated with the condenser, for throttling condensed refrigerant coming from the condenser; (d) an evaporator communicated with said throttling device, having water circulating therewithin, capable of effecting heat transfer between the refrigerant coming from the throttling device and the circulating water; (e) an absorber communicated with the evaporator, having solution reservoired therewithin, for absorbing refrigerant coming from the evaporator by means of the reservoired solution; and (f) a heat exchanger communicated with the absorber and the generator, for performing indirect heat exchange between solution coming from the generator and solution coming from the absorber, characterized in that a solution mixing device, disposed between the heat exchanger and the generator, is provided for mixing solution leaving the generator and solution going to enter the generator. The system disclosed is capable of increasing the performance of heat transfer in the generator and reducing the cost of the generator, and thermal stress will also be reduced.

摘要： 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.
