Temperature and humidity independently controlled air conditioning system

Abstract

The invention relates to a temperature and humidity independently controlled air conditioning system which comprises a high temperature water chilling unit, a chilled water pump, indoor sensible heat terminal devices, an air precooling module, a solution dehumidification treatment unit and a solution regeneration treatment unit; an outlet of the high temperature water chilling unit is connected with inlets of the indoor sensible heat terminal devices, the air precooling module and the solution dehumidification treatment unit through the chilled water pump, and outlets of the indoor sensible heat terminal devices, the air precooling module and the solution dehumidification treatment unit are connected with the high temperature water chilling unit to form a loop; part of high temperature cooling water generated by the high temperature water chilling unit is fed in the indoor sensible heat terminal devices to undertake an indoor temperature adjusting task, part of high temperature cooling water is fed in the air precooling module to carry out pre-cooling treatment on fresh air, and part of high temperature cooling water is fed in the solution dehumidification treatment unit to cool circulated spraying solution. The temperature and humidity independently controlled air conditioning system provided by the invention can independently adjust the indoor temperature and humidity, develops energy efficiency advantages of a high temperature cold source to the utmost extent, can preferably meet the indoor temperature and humidity adjusting demands and realizes the efficient running of the air conditioning system.

Description

technical field [0001] The invention relates to an air-conditioning system, in particular to an air-conditioning system with independent temperature and humidity control based on solution dehumidification. Background technique [0002] Indoor temperature and humidity control is an important task in the process of creating a hot and humid environment in a building. Conventional air-conditioning systems usually use a single cold source to simultaneously control temperature and humidity, which will lead to waste of energy utilization grades, and will be unable to adapt to indoor conditions. The change of sensible heat load and humidity load will affect the effect of heat and humidity environment regulation. The air-conditioning system with independent temperature and humidity control can use different means to adjust the indoor temperature and humidity: use dry air to bear the indoor humidity load and adjust the humidity, and use a separate sensible heat terminal device and hig...
