cycle in hot and humid weather of bushehr city was simulated. The main purpose
of introducing the cycle was to reduce energy consumption, especially fossil
fuel consumption, in vapor compression systems which are commonly used in buildings.
To simulate the cooling cycle, a proper thermodynamic models and physical properties
for each components of the system must adopted. A model for liquid desiccant
system simulation was selected and coding was done in ESS based on experimental
relations was used. The effects of regeneration temperature, thermal comfort
condition and outdoor weather conditions such as air humidity were examined.
In addition, in order to reduce further fossil fuel consumption in vapor compression
cycle, the organic Rankine cycle was combined with vapor compression cycle so
that required inlet work for compressor was supplied. Solar energy was adopted
as the main required heat source for operation of organic Rankine cycle given
the geographic potential of the area. A model of the solar system was simulated
in TRNSYS and optimum values for all elements of the solar system were obtained
based on Solar Fraction. Dynamic performance of the cycle in Bushehr city was
analyzed in an area of 1000 m2 and with cooling capacity 50TR. The
effects of significant parameters on the COP of the cycles, air outlet temperature
and rate of energy consumption in the compressor were investigated along with
the effect of outdoor condition on reaching thermal comfort. Results indicated
that using solar energy with combined cooling system (vapor compression and
liquid desiccant) cuts fossil fuel consumption about 50%. In addition, outcomes
demonstrated that removing moisture from supply air by using a dehumidifier
section in desiccant section of proposed cycle leads to 13% reduction in building
cooling load in summer.]]>Andrusiak, M., S.J. Harrison and L. Mesquit,20102010pp: 17221729Chebbah, A.A.,20022002pp: 547559Gandhidasan, P. and M.A. Mohandes,20103611801186Mago, P. and D.Y.
