Between the triple-point and critical: point temperatures of water, two states liquid and vapor—may coexist in equilibrium, These states are called sturatedliguid and satu- sated vapor In determining a number of moist air properties, principally the saturation humidity ratio, the water vapor saturation pressure is required.

Schematic of Air Conditioned Space Space Heat Absorption and Moist Air Moisture Gains "The problem of airconditioning space is usually determined by 1 the quantity of moist air to be supplied, and 2 the air condition recessary to remove given amounts of energy and water from the space and be withdrawn a «specified condition Figure 10 schematically shows a space with incident rates of energy and moistue gains, The quantity 4, denotes the net sum of all rates of heat gain inthe space, arising trom wansfers through boundaries and ftom sources within the space.

Explores Empirical and Theoretical Prediction Models The book clearly defines the terminology and elucidates the theory behind the measurement techniques, including applications and limitations of each method.
It includes data on sources of error in measurement techniques and experimental data from the literature in graphical or tabular form. The volume also elucidates empirical and theoretical prediction models for different foods with processing conditions, descriptions of the applications of the properties, and coverage of where and how to use the data and models in food processing. User-Friendly Format Puts the Latest Information within Easy Reach Still under the aegis of Shafir Rahman, the new edition is now an edited volume, benefitting from the input and expertise of numerous contributors spanning both the globe and the many disciplines that influence the field.
Presented in a user-friendly format, the second edition remains the definitive, and arguably the only, source for data on physical, thermal, thermodynamic, structural, and acoustic properties of foods. This information helps system designers and operators in selecting and using equipment.
ASHRAE Technical Committees in each subject area have reviewed all chapters and revised them as needed for current technology and practice.
This volume includes data and guidance on cooling, freezing, and storing food; industrial and medical applications of refrigeration; and low-temperature refrigeration.
