Abstract
A hybrid air conditioning system for an enclosed space in a building is comprised of a refrigeration subsystem handling the enclosed space sensible heat load and of a liquid desiccant dehumidification subsystem handling the enclosed space latent heat load. The dehumidification subsystem primarily utilizes available heat from the refrigeration subsystem for liquid desiccant regeneration and dehumidifies ventilation air from the ambient atmosphere for subsequent mixing with enclosed space recirculated air to control the relative humidity within the enclosed space to a desired level. Total system performance efficiency is improved by a novel arrangement and control of system elements.
Claims13
Hybrid air conditioning system apparatus (10,50) for controlling the condition of air circulated in a building enclosed space and comprising a refrigeration subsystem (12,51) effecting temperature reductions in said air and a liquid desiccant dehumidification subsystem (13,60) effecting moisture content reductions in said air, said dehumidification subsystem having:
- a. liquid desiccant dehumidifier means (15,61);
- b. evaporative cooling means (21,73) cooperating with said dehumidifier means;
- c. air-cooled liquid desiccant regenerator means (22,62) cooperating with said dehumidifier means;
- and
- d. air-to-air recuperative heat exchanger means (40,63) cooperating with said regenerator means,
- said regenerator means having louver control means (43,83) cooperating with said air-to-air recuperative heat exchanger means and being selectively operable to vary the quantity of moisture removed from desiccant solution previously heated by said refrigeration subsystem for processing in said desiccant regenerator means.
