Abstract

The invention belongs to the field of absorption refrigeration circulation, and specifically discloses an absorption refrigeration circulation system and a working method thereof. The circulation system comprises a generator, a heat exchanger, a solution pump, an absorber, a first circulation unit and a second circulation unit. A gas-liquid separator is additionally arranged in the first circulation unit, and a first gas flow control valve is arranged on a pipeline for connecting an outlet of the generator with an inlet of a first ejector. An outlet of the gas-liquid separator is connected with an inlet of a second condenser through a circulating pipeline, and a second gas flow control valve is arranged on a circulation pipeline. A temperature sensor is arranged beside the first evaporator and the second evaporator, and the temperature sensor, the first gas flow control valve and the second gas flow control valve are connected with a control system. Refrigerant steam is introduced into the second condenser of the second circulation unit through the second gas flow control valve, directly exchanges heat with a refrigerant and acts on the second evaporator as a refrigerant working medium, and it is guaranteed that the refrigerant flow in the first circulation unit is not changed.

Description

technical field [0001] The invention belongs to the field of absorption refrigeration cycle, and in particular relates to an absorption refrigeration cycle system and a working method thereof. Background technique [0002] Today, when human beings are troubled by the warming of the earth's climate and the thinning of the atmospheric ozone layer, the concept of energy conservation has expanded from simply protecting resources for the benefit of future generations to more urgently protecting the environment. The absorption refrigeration cycle uses environmentally harmless refrigerants, such as water, ammonia, alcohol, etc., as refrigerants, and can use various thermal energy such as steam, waste heat, waste heat, fuel oil, gas, etc. The energy utilization rate and the treatment of the three wastes are very ideal. At the same time, the absorption refrigeration cycle has the advantages of less moving parts, safety and reliability, no harm to the environment and the atmospheric ...
