A refrigeration cycle using R$410$a is being used to cool down produce at the local supermarket. The outside ambient temperature is $35$oC$,$ and the cool space inside for the produce is to be kept at $20$oC$.$ The high side condenser is operating at $2$MPa, and the evaporator is working at $400$kPa. For this assumed ideal system, determine the Coefficient Of Performance $($COP$),$ $?$ Draw of sketch of the cycle and an associated T$-$s diagram. Units are SI $($N$-$m$-$sec$).$
