A standard air conditioning system uses a compressor to increase the pressure on the gas, forcing it into a liquid in the condenser coil. The change of state of the refrigerant starts to take place approximately 2/3rds of the way down the condenser.

A Solar Hybrid Air Conditioning System uses a different method. It uses the heat from the sun to superheat the refrigerant which enables it to begin changing state in the top 2/3rds of the condenser coil.

The main equipments include: CPC collector array, heat storage facility, gas boiler, turbine generator unit, and condenser, water circulating pump, valves and pipelines.
This paper designs a solar-heated generation system with
10kW of electricity generation. The steam temperature at the
inlet of turbomachine is 250? with the inlet pressure is
2MPa.
The analysis of four typical working processes under the
different weather conditions is as follows:
(1) When the weather is fine, the steam at the outlet of
collector with high temperature can satisfy the request of

An adsorption Activated Carbon/Methanol air conditioning system was developed by Wang in 2001 to be powered by heat sources with temperatures close to 100 °C. Evacuated tube collectors could be used to supply hot water at this level of temperature. The system, had two adsorbers with 26 kg of carbon inside each one and used methanol as refrigerant. The COP and the SCP of this system were significantly influenced by the cycle time.

There are 4 loops in this single-effect absorption LiBr/Water solar air conditioning system.
1. LiBr/H2O Loop
2. Chilled Water Loop (could flow space air and cool that instead)
3. Solar Hot Water Loop
4. Cooling Water Loop (to cool condensor & absorber)(could use air)
Typical coefficient of performance (COP) for large single-effect machines are 0.7 to 0.8.
The internal operation of a lithium bromide-water
absorption chiller is intimately influenced by the pressures
and concentrations of its working fluid. In its most basic
