This document summarizes the psychrometric lab capabilities for performance testing of air conditioners. The lab can test cooling capacity, power consumption, efficiency ratings, operating conditions, freeze up, sweat tests, air flow, and noise for window, split, and inverter AC units using refrigerants like R410A, R32, and R290. The lab is NABL accredited and can test units with cooling capacities from 9,000 to 60,000 BTU/hr following IS and ISO standards. It also outlines the process for AC manufacturers to utilize the lab for testing and report generation.
