Abstract
Description
The present invention relates to an air conditioning system, and more particularly, to a hybrid air conditioning system capable of improving energy efficiency through a combination of a liquid dehumidifying cooling apparatus and a compressed heat pump.
In the detailed description and claims of the present invention, "air conditioning" refers to controlling the condition of air supplied to various purpose-purpose facilities including buildings as well as industrial facilities, refrigeration or warm storage, etc. It means performing at least one of dehumidification and humidification. That is, the hybrid air conditioning system of the present invention is not limited to the specific use illustrated, and may be applied to various air conditioning systems for controlling the state of air for any purpose.
Operation of the dehumidification cooling cycle using a liquid dehumidifying agent (hereinafter referred to as a dehumidifying liquid) dehumidifies the air at a low temperature, dehumidifies the air by diluting the concentration of the dehumidifying liquid, and releases water vapor into the air at a high temperature. It was made possible by The exchange of water vapor between the air and the dehumidifying liquid depends on the relative amount of steam partial pressure in the air and the vapor pressure on the surface of the dehumidifying liquid in contact with the air. The steam pressure on the surface of the dehumidifying liquid is a function of the temperature and concentration of the dehumidifying liquid. That is, dehumidification of the humidifier is performed through the absorption process at a low temperature depending on the steam pressure difference between the dehumidified liquid and the air at a given steam pressure, and the dehumidification of the dehumidified liquid through desorption at a high temperature regeneration.
In the absorption process, not only the condensation heat due to the condensation of steam on the surface of the dehumidifying liquid but also the heat of absorption due to the mixed heat is always generated. Therefore, in order to improve the dehumidifying ability, it is necessary to cool the dehumidifying liquid. On the other hand, in the dehydration process of the dehumidifying agent, that is, in the regeneration process, heat input is required to evaporate the water absorbed in the dehumidifying liquid to a concentration suitable for reuse.
1 illustrates a liquid-type dehumidification air conditioning system of a conventional packing tower type, in which a dehumidifier is dehumidified of air and a regenerator is regenerated. In the dehumidifier, the hot / humid air 1 is in direct contact with the dehumidifying liquid 2 flowing through the filler inside the dehumidifier in the dehumidification process in which the dehumidifying liquid absorbs water vapor in the air. Water vapor in the air is condensed / absorbed at the surface of the dehumidifying liquid, and this dehumidification process is adiabatic at constant enthalpy. At this time, the temperature of the air is slightly increased and the absolute humidity is decreased. Process air (3) dried through the dehumidification process is cooled while passing through the evaporative cooler (4) is made of air (5) of the desired temperature and humidity.
While the dried process air 3 passes through the evaporative cooler 4, the temperature of the air is lowered, and the absolute humidity is also slightly lower than the original state. The ability of the dehumidifying solution to absorb water vapor decreases with increasing water content, and dehumidifying solutions containing more than a certain amount of water can be used again in the dehumidification process only after being regenerated through a regeneration cycle. Therefore, the dehumidifying solution dilute solution 6 which absorbs moisture in the air in the dehumidifier and is diluted is sent to the regenerator. The dehumidifying solution of the regenerator is passed through the solution heater 11 to facilitate the absorption of moisture absorbed into the regenerated air. The dehumidifying liquid heated in the solution heater (11) is distributed in the solution distributor (10) and discharges the moisture in the dehumidifying solution to the regeneration air while contacting the regeneration air (8) in the regenerator to be converted into a concentrated solution (7). The regenerated
