Two Stage Cooling System

A two stage evaporative cooling system can deliver cool indoor air with low relative humidity compared to direct evaporative cooling systems which typically deliver the air at around 70 80 relative humidity.

Two stage cooling system.

This cooling option is energy efficient in comparison with the refrigerant cooling technology which only provides with standard air. The two stage evaporative cooling system also known as direct or indirect cooling is the most advanced and technologically developed cooling system using the utilizing evaporative cooling technology. High for hot summer days and low for milder days. Two stage cooling means the air conditioner or heat pump has a compressor with two levels of operation.

Two stage cooling refers to the type of compressor that s in the outside condensing unit.

Unlike a single stage unit that can only get within 4 6 f of the set temperature a two stage unit can get within 2 f. 2 stage conventional cooling system will have wires leading into terminal y and y1 or y1 and y2 two stage thermostat 2 heat 2 cool option note.

Problems with two stage air conditioners. Since the low stage is adequate to meet household comfort demands 80 of the time a two stage unit runs for longer periods and produces more even temperatures. Greater comfort because the two stage air conditioner runs more often it will provide more even cooling and can remove twice as much moisture humidity from your air.
