Experimental analysis on PV/T-SAHP performance under the influence of the Electronic Expansion Valve
Under different Electronic Expansion Valve (EXV)opening degree at the fixing frequency of 50hz of the compressor,we had test the system performance.When the cooling refrigerant influence to the PV module and the heating air influence to the collector / evaporator reached the balance,the photoelectric efficiency achieved the maximum.When the EXV opening degree fixing,with the raising of the solar radiation,the compressor power values appeared oscillation,and the oscillation was especially evident when the EXV at the maximum opening degree.So we put forward the PV/T-SAHP system stability principle.At the same time,we found that the key of the PV / T-SAHP research is to discover the relation between the solar radiation and the superheat of collector / evaporator.
