Answer 1

Answer (1) can be an Annual Domestic thermal load. Annual domestic thermal wad define amorent of thermal energy needed domestic needs within Thermal load can be calculated to summition of all the is devidual loads demand in country. country for cette a year by the Thermal closed Power Generation Refeigration & Airconditioning Other fields can Fig: Block diagram of thermal load demands. Thus calculate the domestic thermal cload by using above defination and bluck diagram. In have to add all the load requirement to get the total lood in a year for a particular country. this process

corentry this oo and per the geographical location of Erenties ; each have it is unique longitude and latitude position Due to position weather conditions of the crenties also varies- Templenture increases if the Countries Ilies near the equator. these corenties require lower heating load but higher cooling lad On the other hand, the counters which lies the poles have lower tempt. These corentzies require higher heating cload white lower cooling load Thus heating and cooling cload vary between countries. near Thank Yoy!
