Investigation of the Operation of Inverter Units for the Possibility of Working in the Cooling Mode at Low Outdoor Temperatures

Abstract

The possibility of avoiding problems associated with low outdoor air temperatures at the design stage of the air conditioning system of a responsible object is considered. A study was conducted in laboratory conditions to determine the operability of inverter split systems at an ambient (outdoor) air temperature of “minus” 30°C. As a result of field tests in laboratory conditions, the possibility of operating inverter split systems in cooling mode at an ambient temperature of “minus” 30°C is presented.
