Solar A/C
Solar air conditioning refers to an air conditioning (cooling) system that uses solar power, power from the heat obtained...
Why Solar?
The market for cold supply is increasing especially in warmer climates, but also in temperature regions.

  Classification of air conditioning techniques
  Schematics of solar air conditioning and the different circuits used
  • Solar heat will be used to produce steam/ hot water as a first step. This circuit is shown in Blue colour. This is a closed loop. Same water is circulated. There is no external electrical heat used.
  • The steam passes through the absorption chiller, loses its heat to the Refrigerant (Lithium Bromide/Water solution) and returns to the tank for recirculation again.
  • Refrigerant ( Shown in Orange takes the heat from the steam and using the adsorption cycle explained in the write up, produces chilled water from the second loop of water entering the Absorption chiller.( Shown in Green.)
  • The chilled water passes through the Heat exchanger, and cools the air to the required temperature, that in turn cools the target room.
  • The chilled water stored in the tank is increased to continue cooling during the hours when the sun is not shining. It also acts as the buffer for the times when the cloud or other factors affect the amount of heat from the sun.

  Vapor Absorption Air-Conditioning System
  1. Lean Solution pumped To the Generator
  2. Water Vapors formed as result of Heating by Solar Heated Fluid
  3. Water Vapors move from Generator to Condenser where it is condensed by Cooling Water
  4. Water flows to the Evaporator. Expansion Valve provided to reduce the pressure
  5. The Water gets evaporated at a low Temp given the Vacuum maintained in the Evap, taking away the heat from the Incoming Water thereby cooling it
  6. Water Vapors move to the Absorber
  7. Conc. LiBr Sol loses heat to the Lean Sol in the Pre-heater and is sent to the Absorber to absorb the Water Vapor produced in the evaporator
