Supplementary combustion type absorption air conditioning large temperature difference heating integrated unit

Abstract

A supplementary combustion type absorption air conditioning large temperature difference heating integrated unit, including supplementary combustion type absorption air conditioning heat pump unit, transmission and distribution system and cooling system; wherein supplementary combustion type absorption type air conditioning heat pump unit includes low temperature generator, condenser, Evaporators, absorbers, post-firing high-temperature generators, sanitary water heaters, heating water heaters, low-temperature solution heat exchangers, high-temperature solution heat exchangers, solution pumps and refrigerant pumps; transmission and distribution systems include plate-plate heat exchangers, filtration The cooling system includes a cooling tower and an automatic dosing device; the above-mentioned afterburning type absorption air-conditioning heat pump unit, transmission and distribution system and cooling system are connected and combined through valves and pipelines. The invention utilizes the urban heating network for heating in summer and winter use, and also provides sanitary hot water. When the heating of the urban heating network is insufficient in winter, it can supplement combustion to improve the heating effect, has complete functions, saves energy and reduces consumption, and has good technical performance of the whole machine.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an integrated unit for providing cooling in summer, heating in winter and long-term sanitary hot water for building complexes. Background technique [0002] In northern China, water-to-water plate heat exchange heating units with small temperature difference and large flow are basically used for heating in winter. With the advancement of technology in recent years, absorption-based large temperature difference heating units have also emerged. The heat unit is a water-to-water plate heat exchanger and an absorption heat pump installed together through pipes. The two heat exchange methods work in parallel to form the effect of heating with a large temperature difference. However, the following problems still exist during operation: Under some specific conditions, users need to cool in summer, heat in winter, and provide sanitary hot water throughout the year. A...

[0002] In northern China, water-to-water plate heat exchange heating units with small temperature difference and large flow are basically used for heating in winter. With the advancement of technology in recent years, absorption-based large temperature difference heating units have also emerged. The heat unit is a water-to-water plate heat exchanger and an absorption heat pump installed together through pipes. The two heat exchange methods work in parallel to form the effect of heating with a large temperature difference. However, the following problems still exist during operation: Under some specific conditions, users need to cool in summer, heat in winter, and provide sanitary hot water throughout the year. According to the previous model, two to three systems are needed to meet user requirements, that is, air conditioners are used for cooling in summer, and plate-plate heat exchange units are used. The urban heating network supplies heat in winter, and the boiler provides sanitary hot water

However, the heating effect cannot be improved when the heating network in the city is insufficient, and the three systems occupy a large area, require a lot of investment, high energy consumption, and complicated operation and control
