Temperature Control of Solar Air Conditioning Systems
This thesis investigates the problem of regulating the temperature of a conditioned space using a Solar Assisted Air Conditioning Systems (SAACS) prototype located at Cabo Rojo, Puerto Rico. The SAACS Prototype consists of a 66 flat plate solar collector array with 115.4 m 2 of selective surface area, a 35 kW single-effect lithium-bromide absorption chiller, a 84 kW cooling tower, a 50 kW auxil...
متن کاملPerformance analysis and working fluid selection for geothermal energy-powered organic Rankine-vapor compression air conditioning
Results: The calculated results show that because of high system pressure for R290 and R134a, R600a is the more suitable working fluid for ORC in terms of expander size parameter, system efficiency and system pressure. In addition, R600a is also the most appropriate working fluid for VCC in terms of pressure ratio and coefficient of performance. R600 and R600a are more suitable working fluids f...
متن کاملSelection of the optimum prime mover and the working fluid in a regenerative organic rankine cycle
A regenerative organic Rankine cycle (RORC) is modeled and optimized for the use of waste heat recovery from a prime mover (PM). Three PMs including, a diesel engine, a gas engine, and a microturbine are selected in this study. Four refrigerants including isobutane, R123, R134a, and R245fa are selected. The nominal capacity of the PM, PM operating partial load, turbine inlet pressure, condenser...
متن کاملThe optimum pressure for working fluid in feed water heaters of steam power plants
The aim of this study is to find the optimal water pressure and percentage of supply vapour in the feed water heaters (fwhs) of steam power plants, such that they maximize the thermal efficiency of the Rankine cycle within pre-specified values of minimum and maximum pressures of the thermodynamic cycle. Thermal efficiency is defined as a function of unknown variables (fluid pressure and vap...
متن کاملDevelopment of a Pilot Plant Solar Liquid Desiccant Air Conditioner for the Northern Region of Iran
In a 10-ton capacity pilot plant solar liquid desiccant air conditioner (LDAC) developed, dehumidification of the outside air is achieved through a honeycomb packed-bed heat and mass exchanger, using lithium chloride solution as the desiccant. The dry air obtained from the dehumidification process is evaporative cooled inside a cooling pad and directed into the conditioned space. The dilute sol...
