Reading enthalpy psychrometric chart
WebThe psychrometric chart is built upon two simple concepts. 1. Indoor air is a mixture of dry air and water vapor. 2. There is a specific amount of energy in the mixture at a specific temperature and pressure. Indoor Air is a Mixture of Dry Air and Water Vapor The air we live in is a mixture of both dry air and water vapor. Both are invisible gases. WebEnthalpy Enthalpy is Point 5 on the chart. Enthalpy is a quantity that is equal to the total heat content of a system. This is measured in BTU (British thermal unit) per pound of dry air. ... Reading a psychrometric chart isn’t …
