Predictions of the Temperature and the Humidity
in Wrapper Type Cold Store (Part 1)
- under quasi-steady state operation -

Shi-Qing WANG, Shun-ichiro TANAKA, Fumihiko TANAKA and Kazuo MORITA

Summary

    Numerical model equation was developed to predict or to control the temperature and humidity of air in wrapper type cold store. The model was based on heat and mass balance of moist air, and was solved using the Runge-Kutta-Gill method. Exhaust air conditions from an unit cooler and outer air conditions were used as model inputs. For validation of the model, data were collected. The model predicted temperature and humidity of moist air compared reasonably well with the observed values. Air conditions in wrapper were maintained constant when the store system was under quasi steady state operation.

Keywords: wrapper type cold store, temperature, humidity, enthalpy, heat and mass balance, Runge-Kutta-Gill method
