![]() ![]() Smart Fabric Provides ‘Air Conditioning’ for the Wearer, Adjustable with Mobile AppĮnergy Efficient, Passenger-Focused Air Conditioning Liquid cooling for precise temperature control Part 3 of this article details how the underlying physics principles of heat and heat transfer were translated by Carrier into a viable air-conditioning system. The chart is widely available online, of course, and also as printed pads. Many versions of the chart highlight an area in the center – bounded approximately by 68⁰F and 82⁰F (20⁰F and 28⁰C) on the left and right, and 30 to 70 percent relative humidity on the top and bottom – as the zone in which most people feel comfortable. Once you know this point, you can determine all the other air-property variables at this state point. (Image: )Ī single point on the psychrometric chart is defined by the intersection of any two-variable lines and represents a unique “state point” for air properties. (Image: Parker Hannifin Corp) Fig 4: This simplified (metric) psychrometric chart shows the relationship among the critical air-property variables it defines a specific state point based on the intersection of any two property lines.
