I had a Haier No Frost refrigerator 16CFT. which is almost 15 years old. Every one in the house always complaining that its cooling cant even compete with the older Mitsubishi which was Direct cool and a Dawlance (newer one) which is direct cool. Condition of cooling gets worse specially in peak summer months. I am now planing to buy a Haier Direct Cool, same capacity but with DC-Inverter Compressor.
Furthermore, the no-frost refrigerator they are advertising that can run on UPS consumes more than 400 Watts for its heating coils, so u cant run it on 1KVA UPS with rest of the household load. If you dont wanna put no-frost on UPS, u have to manually install a small UPS (worth Rs3500-4500) to keep its internal circuit powered-up, otherwise if loadshedding happens it will reset its clock and will not turn on heaters on time causing low cooling.
In a nut-shell, go for direct cool with DC-Inverter Compressor... simpler, newer compressor technology.... better cooling in pakistani climate.
hope this helped you
