Abstract

The invention belongs to the field of absorption refrigeration cycle, and specifically discloses an absorption refrigeration cycle system and a working method thereof. The cycle system includes a generator, a heat exchanger, a solution pump, an absorber, a first circulation unit and a second circulation unit ; A gas-liquid separator is added in the first circulation unit, and a first gas flow control valve is provided on the pipeline connecting the outlet of the generator with the inlet of the first injector; the outlet of the gas-liquid separator is connected with the circulation pipeline through the The inlet of the second condenser is connected, and the circulation pipeline is provided with a second gas flow control valve; a temperature sensor is provided beside the first evaporator and the second evaporator, the temperature sensor, the first gas flow control valve and the second gas The flow control valve is connected to the control system. It is introduced into the second condenser of the second circulation unit through the second gas flow control valve, and conducts direct heat exchange with the refrigerant, and acts as a refrigerant working medium in the second evaporator to ensure the refrigerant in the first circulation unit. Flow remains unchanged.

Description

technical field [0001] The invention belongs to the field of absorption refrigeration cycle, in particular to an absorption refrigeration cycle system and a working method thereof. Background technique [0002] Today, when human beings are troubled by global warming and the thinning of the atmospheric ozone layer, the concept of energy saving has expanded from the simple protection of resources for the benefit of future generations to the more urgent aspect of protecting the environment. The absorption refrigeration cycle uses environmentally harmless refrigerants, such as water, ammonia, alcohols, etc. as refrigerants, and can use various thermal energy such as steam, waste heat, waste heat, fuel oil, gas, etc. as the driving force. It is ideal for energy utilization and three waste treatment. At the same time, the absorption refrigeration cycle has the advantages of few moving parts, safety and reliability, harmless to the environment and the atmospheric ozone layer, high...
