Abstract

A photovoltaic powered vapour-compression air conditioner system coupled directly to 2 kW PV array was designed and tested as part of solar houses cooling program in KISR, KUWAIT. Analysis of such systems is reviewed and discussed to optimize the power matching of the mechanical load to the PV array electrical characteristics. 
The concept 18 employing a variable speed seperately excited D.C. motor. Motor starting and operation at low levels of solar insolation is enhanced by introducing switching network and variation of flux and armature resietance. Various modules ars switched in parallel under high current demand conditions and at early and late hours of the day to increass the utilizability of the system. Analysis of other types of A.C and D.C motors and compressors w.r.t their corresponding starting systems are reviewed and dis cussed, Energy storage is incorporated in the form of chilled water (end us? energy form in order to avoid the electrical storage baztoriss with their high cost and low charge/discharge (round trip) efficiency. 
The tests carried confirm that high array utilization can be achieved by this approach without either secondary battery storage at the array output or expensive DC-AC inverter.
