Specific heat (C) is the amount of heat required to change the temperature of a mass unit of a substance by one degree. Isobaric specific heat (Cp ) is used for air in a constant pressure (ΔP = 0) system. I sochoric specific heat (Cv ) is used for air in a constant-volume (isovolumetric or isometric) closed system. Note!
dehumidification effectiveness of air conditioning equipment is commonly characterized by the sensible heat ratio (SHR), which is the ratio of the sensible cooling capacity to the total (sensible + latent) cooling capacity.
The specific heat (= specific heat capacity) at constant pressure and constant volume processes, and the ratio of specific heats and individual gas constants - R - for some commonly used " ideal gases ", are in the table below (approximate values at 68oF (20oC) and 14.7 psia (1 atm)).
In thermal physics and thermodynamics, the heat capacity ratio, also known as the adiabatic index, the ratio of specific heats, or Laplace's coefficient, is the ratio of the heat capacity at constant pressure (C P) to heat capacity at constant volume (C V).
Ratios of specific heat for gases with constant pressure and volume processes. Internal Energy. For an ideal gas the internal energy - u - is a function of temperature. A change in internal energy can be expressed as. du =cv dT (1) where. du = change in internal energy (kJ/kg)
Right-sizing of a residential heating, ventilation, and air conditioning (HVAC) system involves the selection of equipment and the design of the air distribution system to meet the accurate predicted heating and cooling loads of a house.
