Problems solved by technology
[0003] Among them, the condenser is the key component to realize adsorption refrigeration. It is found in the research that when the negative pressure adsorption refrigeration system is running, the non-condensable gas in the system will continue to accumulate in the condenser, which will greatly reduce the condensation efficiency of the condenser, thus affecting the Overall performance of the entire adsorption refrigeration system

The invention discloses a condenser for a negative pressure adsorption type refrigerating system. The condenser comprises a cylinder block and a heat exchange pipeline. The heat exchange pipeline is arranged in the inner cavity of the cylinder block and is used for forming a cooling water loop. At least two steam pipelines are connected to the side wall of the cylinder block. Each steam pipeline is connected with an adsorption bed. A water return pipeline is connected to the bottom of the cylinder block. The steam pipelines, the inner cavity of the cylinder block and the water return pipeline are connected to form a section of refrigerant loop. A gas emission device used for collecting noncondensable gas emitted outwards is arranged at the top of the cylinder block. In the condenser, the gas emission device is arranged at the top of the cylinder block, and the noncondensable gas generated during the operation process of the condenser is gathered to the highest point, is collected and stored in the gas emission device, and is separated and emitted regularly through the gas emission device, so that efficient heat exchange of the condenser is ensured.
Description
technical field [0001] The invention relates to the technical field of adsorption refrigeration, in particular to a condenser for a negative pressure adsorption refrigeration system. Background technique [0002] Adsorption refrigeration is a green and environmentally friendly refrigeration technology, which is completed alternately by two processes of heating-desorption-condensation and cooling-adsorption-evaporative refrigeration. Driven by thermal energy, the refrigerant adsorbed by the adsorbent in the desorption adsorber replaces the role of the traditional compressor to generate high-temperature and high-pressure steam, which is then condensed by the condenser, and the energy-saving device expands and reduces pressure, and returns to the evaporator. Then the adsorber is cooled, the pressure is reduced, the refrigerant evaporates, and the adsorbent absorbs the refrigerant vapor to achieve continuous refrigeration for a period of time until the adsorption is saturated. ...
