That's wonderful, and great to know that Mitsubishi Electric Mr. Slim Non-Inverter performed that well!
there r certain design parameters followed while manufacturing an ac .. like vent or duct temp .. too cool pipes will freeze .. air will choke .. too hot and it wont take out moisture .. so if i remember correctly then ideal duct or vent temp is 4-7 deg C. next comes blower size and speed .. which dictates the throw of cool air .. last is size of evaporator .. the bigger the more the cooling and obviously its size is as per tonnage .. even the BTU is based on some criteria .. there is no difference in a conventional ac or an inverter in terms on cooling (with respect to tonnage) .. its only the working principle which is diffrent .. BTW mitsubishi mr. slim is 13000 btu which is slightly higher than 1 ton ac (12000 btu) .. only orient and mitsubishi sold in 13000 and 19000 btu category
Sir those were the days when misubishi and lg units made in Korea were available.i have lg installed and alhamdolillah not a single leakage ,or gas refilling since 2006.clean it's evaporator with foam spray and pressure washer every alternate season
