Mollier diagram: Energy Management & VentilationWhen ventilating a greenhouse, you’re not just exchanging air—you’re exchanging energy. Enthalpy represents the total heat content of air, including sensible heat (temperature) and latent heat (water vapor). The difference in enthalpy between inside and outside air determines:…

Mollier diagram: Understanding Temperature & HumidityA Mollier diagram is a technical chart used to visualize the thermodynamic properties of moist air. It plots enthalpy (energy content) against absolute humidity, with overlays for temperature, relative humidity (RH), and other air parameters. In greenhouse climate…

Background: Absolute Humidity, Relative Humidity, and Humidity DeficitHumidity is a critical factor in greenhouse management, affecting plant transpiration, disease risk, and climate control. But humidity can be measured and expressed in several ways, each offering different insights. This article explains the differences between absolute humidity,…
