加拿大一家研究机构开发了一个稳态水-空气热泵建模程序SIMPAC，以非共沸制冷剂混合物模拟为特色。SIMPAC中使用了Camahan Starling-Desantis（CSD）状态方程，这是Domanski（1986）发布的HPBI计划的后续发展。该模型已在纯制冷剂R22和混合物R13B1/R152a和R22/R114中成功验证。然后用它来预测R22/R23的行为。本文概述了该模型及其验证。引文:ASHRAE交易，第卷。 95分。1989年，温哥华

A Canadian research institute has developed a steady-state water-to-air heat pump modeling program, SIMPAC, featuring non-azeotropic refrigerant mixture simulation. The Camahan-Starling-Desantis (CSD) equation of state is used in SIMPAC, which is a follow-on development of the HPBI program published by Domanski (1986). This model has been successfully validated for pure refrigerant R22 and mixtures R13B1/R152a and R22/R114. It was then used to predict R22/R23 behavior. This paper provides an overview of the model and its validation.
