Abstract

The invention discloses an absorption heat pump and an evaporator and a method thereof. The evaporator of the absorption heat pump comprises a flashing cavity, an evaporation heat exchanger, an evaporator condensation working medium spraying pipeline, an evaporator condensation working medium spraying pump and an evaporator condensation working medium spraying device, wherein the evaporation heat exchanger is arranged outside the flashing cavity, the evaporator condensation working medium spraying pipeline is connected to the cold fluid side of the evaporation heat exchanger, the evaporator condensation working medium spraying pump arranged on the evaporator condensation working medium spraying pipeline conveys working media inside the flashing cavity to the evaporator condensation working medium spraying device through the evaporator condensation working medium spraying pipeline after the working media undergo heat exchange by the evaporation heat exchanger, the evaporator condensation working medium spraying device sprays the working media into the flashing cavity, and parts of the working media become steam inside the flashing cavity in a flashing mode. According to the absorption heat pump and the evaporator and the method thereof, the heat transfer and mass transfer process of evaporation of the condensation working media of the evaporator can be reinforced, and the size of the evaporator can be reduced.

Description

technical field [0001] The invention relates to the technical field of heat pump cycles in thermal energy engineering, in particular to an absorption heat pump, an evaporator and a method thereof. Background technique [0002] Absorption heat pumps, including absorption refrigeration systems, first-type absorption heat pump systems, second-type absorption heat pump systems, and other forms of absorption heat pumps, are a type of heat pump that uses heat as a driving force to transfer heat from a low-temperature heat source to a high-temperature Circulation system pumped by heat source. It is an effective device for recycling low-temperature heat energy, and has dual functions of saving energy and protecting the environment. Such as figure 1 As shown, an absorption heat pump generally includes components such as an evaporator 100, an absorber 200, a generator 300, a condenser 400, a heat exchanger, pipelines, and a shielded pump. Wherein, the evaporator 100 and the absorbe...
