### Calculation and Design of the Heat Pumps

heating space of 186 m2 thermal power of 11,4 kW is required. Unit area which requires 1 kW of thermal power will be calculated by the ratio of surface area that is heated and with required thermal power: 2 0 0 186 16,32 11, 4 A m a P kW = = = (1) where: a – unit area A 0 – surface area in the worst case P 0 – thermal power required in the worst case

• ### Boiler Surface Area: More is not Necessarily Better

The conclusion is: Simply deciding on a particular boiler design or supplier simply because the design has more surface area can be wrong. Unless one can perform heat transfer calculations and check the surface area of each boiler, one should stay away from comparing surface areas. I stress this because with easy access to spreadsheets, even .

This results in a recirculation ratio as high as 220 to 330 lbs (100 to 150 Kg) of liquor per pound (kilogram) of water evaporated. These high recirculation rates result in high liquor velocities through the tube which help to minimize the build up of deposits or crystals along the heating surface.

• ### Heat Transfer through Evaporators | Physics Forums

Aug 26, 2013· It can be difficult to accurately calculate all these terms. If you are simply looking for a good approximation of the heat transfer, an energy rate equation (enthalpy eqn) should suffice. In the case of an evaporator, the working fluid (refrigerant) acts as if it has an infinite specific heat capacity and can be assumed as isothermal.

• ### Sugar - Robert Evaporator Technology Design Parameters

Robert Evaporator Design. Design an evaporator for your factory online now. Design Steps. The first and most important step in evaporator design is a thorough and complete heat and mass balance. Once you have chosen or calculated the overall heat transfer coefficients you can calculate the heating surface area required, from the formula: A = Q / k / ΔT L
