ExerPy - v.0.0.7

v0.0.7 (24.02.2026)

Bug Fixes

• Fixed floating-point temperature comparison in HeatExchanger and Condenser components. Added _temperature_case() helper with 0.01 K tolerance to prevent misclassification when stream temperatures are at exactly Tamb.
• Changed case 6 (all streams at Tamb) log level from warning to info in HeatExchanger and Condenser.

New Features

• Added full dissipative component support for Condenser: dis_eqs() method, is_dissipative detection in _construct_components() and analyse(), and NaN-safe exergoeconomic_balance().
• Added dissipative HeatExchanger support: dis_eqs() method and is_dissipative detection in _construct_components() and analyse().
