## 1 Introduction  
Consideration of reducing energy consumption to drive an air conditioning system for heating [1, 2], cooling [3, 4], humidification [5, 6], and dehumidification [7, 8, 9] has gained the attraction of developing an effective system that consumes less energy. For most cases, in hot and humid areas, around 20%-40% of total energy is dominated by air conditioning systems [10]. High energy is required for achieving the cooling and dehumidification load. However, a significant amount of this energy can be reduced by coupling the air conditioning system with alternative energy resources involving solar energy [11, 12], wind energy [13, 14], and waste heat from industrial processes [15, 16]. Additionally, other than using the hybrid or coupling system, the separation of the sensible and latent load can also reduce the power inputs within the system [17]. Therefore, the current study offers an attempt in desiccant dehumidification system utilization, which could be able to handle the latent heat load individually to minimize the energy consumption by the air conditioning system. This system is expected to be used in hot and humid regions when the demand for dehumidification load is dominant. The main issue when using the desiccant system is poor performance due to improper parameter design. Three main factors can determine the performance of the desiccant system: (1) adsorbent/adsorbate pairs [18; 19; 20], (2) properties of the working fluid [21; 22], and (3) design and operating conditions of the system [23; 24]. The proper combination of these three parameters is expected to improve the performance of the system. It was also found that several efforts have been made by researchers to achieve this goal. The development of the desiccant dehumidification system that is driven by solar energy was implemented by [PERSON] et al. [25]. Employing solar energy ensures not only the feasibility but also the achievement of the efficiency of the system. A novel desiccant air-conditioning system, which was coupled with the needle-impeller rotors, was modeled by [PERSON] et al. [26]. Unlike the existing desiccant system, the additional needle-impeller rotor was supposed to improve the heat and mass transfer between the absorber and evaporator. [PERSON] et al. [27] presented an evaluation of the performance of the desiccant cooling system under different ambient temperatures and relative humidity. Adjusting ambient temperature and relative humidity affected the coefficient of performance (COP) and cooling load of the system. The performance decreases when the temperature and relative humidity is increased. Somehow it will approach a zero value when the temperature and moisture become higher. [PERSON] et al. [28] numerically investigated the performance of the desiccant dehumidification systems driven by a low-grade heat source. The study was aimed to determine the minimum heat source temperature to drive the system. They found that the lowest regeneration temperature of 306 K was able to drive the system. [PERSON] et al. [29] proposed design parameters and their effect on the performance of a solid desiccant air conditioning system. The ambient and load conditions were investigated and modeled under steady-state conditions, whereas the result validation was based on the experimental data. The critical parameter for designing the desiccant air conditioning system was the air flow rate and regeneration temperature. The proper mass flow rate and regeneration air temperature not only were downsized the desiccant sysmtem, but efficient thermal energy use was also given. [PERSON] et al. [30] analyzed the performance of the silica gel rotary desiccant-wheel by considering the influence of the regeneration temperature. As they developed the system for a dehumidifier, the performance was evaluated regarding the removal efficiency and dehumidification capacity. They found that increasing the regeneration temperature offers the increment of removal efficiency.
