Single-wheel two-level-dehumidification combined-type air conditioning system and working method

Abstract

The invention discloses a single-wheel two-level-dehumidification combined-type air conditioning system, and belongs to the field of air conditioning. The single-wheel two-level-dehumidification combined-type air conditioning system mainly comprises a primary regeneration filter (1), a primary regeneration condenser (2), a primary regeneration auxiliary electric heater (3), a dehumidification-section fan (4), a dehumidification-section auxiliary electric heater (5), a dehumidification wheel (6), a secondary evaporator (7), a dehumidification-section filter (8), a primary evaporator (9), a secondary regeneration fan (10), a primary regeneration fan (11), a secondary regeneration auxiliary electric heater (12), a secondary regeneration condenser (13) and a second regeneration filter (14). The evaporators and the condensers are referred relative to refrigerant of a vapor compression refrigeration cycle system, and a compressor and an expansion valve are omitted in the picture. Compared with existing wheel dehumidification systems, the single-wheel two-level-dehumidification combined-type air conditioning system has the advantages of high dehumidification efficiency, compact structure, independent temperature and humidity control, obvious energy conservation effect and the like.

Description

technical field [0001] The invention relates to a single-wheel two-stage dehumidification composite air-conditioning system and method, belonging to the field of air conditioning. Background technique [0002] In the past, only the air temperature was used as the main solution index when heat insulation and indoor ventilation were carried out on the building maintenance structure, while the influence of air humidity on the thermal environment was ignored. With the development of the economy and the improvement of people's living standards, the requirements for room comfort are getting higher and higher, the demand for temperature and humidity control is getting stronger and stronger, and the task of air conditioning is becoming more and more heavy. The traditional air conditioner couples the sensible heat load and latent heat load of the room, that is, the dew point dehumidification is realized while the return air is cooled by the cold water coil. In order to dehumidify, a...

Problems solved by technology

[0004] Although the research on the rotary dehumidification system has made great progress in recent years, the design of the rotary dehumidification system has also emerged related technologies, such as the absorption refrigeration based on solar heat recovery and the solid rotary dehumidification air conditioner proposed in patent ZL201210493803.6 system, patent ZL201110206159.5 proposed a two-stage dehumidification and air-conditioning system for ships, etc. Although these technologies have solved the problem of independent control of temperature and humidity, they have not considered the feasibility of the system, and the cost of solar refrigeration and dehumidification systems is too high. low and unstable
