Air conditioning system capable of independently controlling temperature, humidity and cleanliness

Abstract

The invention discloses an air conditioning system capable of independently controlling temperature, humidity and cleanliness. The air conditioning system comprises a high-temperature cold source supply unit, a fresh air processing unit, a return air processing unit and a sensible heat tail end; the fresh air processing unit comprises a first pre-cooling unit, a first solution dehumidification regeneration unit and a first purification processing unit; the first solution dehumidification and regeneration unit comprises a first solution dehumidification module and a first solution regeneration module which form a loop; the first pre-cooling unit, the first solution dehumidification module and the first purification processing unit are arranged on an air supply path; the return air processing unit comprises a second pre-cooling unit, a second solution dehumidification regeneration unit and a second purification processing unit; the second solution dehumidification and regeneration unit comprises a second solution dehumidification module and a second solution regeneration module which form a loop; the second solution regeneration module, the second pre-cooling unit, the second solution dehumidification module and the second purification processing unit are arranged on an air return path; and the sensible heat tail end, the first pre-cooling unit and the second pre-cooling unit form a loop with the high-temperature cold source supply unit.

Description

technical field [0001] The invention relates to an air-conditioning system for independent control of temperature and humidity cleanliness, which belongs to the field of energy, especially the field of HVAC systems. Background technique [0002] The regulation process of the indoor thermal and humid environment of a building includes the regulation of indoor temperature and humidity. Conventional air-conditioning systems usually use a single cold source to realize the regulation of temperature and humidity at the same time, which will lead to the loss of energy utilization grade, and due to It cannot adapt to the hourly changes of indoor sensible heat load and humidity load and cannot realize the effective regulation of building thermal and humid environment. The air-conditioning system usually undertakes many environmental creation and control tasks such as meeting the building temperature, humidity, cleanliness, and fresh air supply. Conventional air-conditioning systems a...

Problems solved by technology

[0004] Compared with conventional above-ground buildings, underground buildings also have higher requirements on environmental parameters such as temperature and humidity, cleanliness, and fresh air supply, and their load composition and sources are significantly different from those of above-ground buildings. Some functional underground buildings have the characteristics of high sensible heat load , but at the same time, the moisture load caused by the moisture dissipation of the underg
