Afterburning absorption type integrated unit for air conditioner large temperature difference heat supplying

Abstract

The invention discloses an afterburning absorption type integrated unit for air conditioner large temperature difference heat supplying. The unit comprises an afterburning absorption type air conditioner heat pump unit, a distribution system and a cooling system; the afterburning absorption type air conditioner heat pump unit comprises a low-temperature generator, a condenser, an evaporator, an absorber, an afterburning type high-temperature generator, a sanitary water heater, a warming water heater, a low-temperature solution heat exchanger, a high-temperature solution heat exchanger, a solution pump and a cryogen pump; the distribution system comprises a sheet type heat exchanger, a filter and water pumps. The cooling system comprises cooling towers and automatic medicine feeding devices. The afterburning absorption type air conditioner heat pump unit, the distribution system and the cooling system are connected and combined. According to the afterburning absorption type integrated unit, cooling is conducted in summer, heating is conducted in winter by using municipal heating systems, sanitary hot water is provided, when the heating in winter by using the municipal heating systems is not sufficient, afterburning is conducted, the heating effect is improved, functions are complete, the energy is saved, the consumption is reduced, and the integral unit is good in technical performance.

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
