Nthalpy solutions
WebEnthalpy ( H) is the sum of the internal energy ( U) and the product of pressure and volume ( PV) given by the equation: H = U + PV When a process occurs at constant pressure, the heat evolved (either released or absorbed) is equal to the change in enthalpy. WebNthalpy’s solutions are designed based on the heat-source temperature, the required temperature lift and the heat recovery rate, which determine respectively; the recovery medium (refrigerant or steam), the number of compression stages and their speed, and …
