ahu-psychro

Psychrometric calculations determine air properties like humidity ratio, enthalpy, and specific volume using saturation pressure equations. This Skill applies Hyland–Wexler equations to compute state properties at design conditions, then performs mixing, cooling, heating, and humidification calculations to verify thermal loads meet ASHRAE requirements.

Sensible Heat Ratio (SHR) is the ratio of sensible to total cooling load. This Skill validates SHR against design constraints to confirm the cooling coil removes the correct mix of sensible and latent heat, ensuring the system meets thermal load targets.

Yes. This Skill reads outdoor and return air conditions, calculates mixed-air properties, then simulates cooling and heating coil performance. It writes results including mixed-air state and verified loads to state/psychro.json for design validation.

This Skill references ASHRAE design-condition data to retrieve outdoor air temperature and humidity targets for specific locations and design scenarios. It applies those conditions to validate system performance against industry standards.

The Skill reads state/request.json (design parameters), state/concept.json (system configuration), and state/constraints.json (performance targets). It produces state/psychro.json containing all calculated air properties, mixed conditions, and load verification results.
