How can I quickly and accurately calculate the heating and cooling capacity required?
The terms “quickly” and “accurately” in this question are mutually exclusive. Either an approximate value of the required heating and cooling capacities can be calculated quickly, or an accurate time-consuming calculation is necessary. When calculating the required performance, different situations must be taken into consideration. In many cases, the circulator is being used for cooling an external system of which a certain amount of energy has to be dissipated. If this amount of energy is known, the circulator must at least provide the required cooling capacity at the appropriate operating temperature. Applications often involve cooling down or heating up within a certain period of time. If the circulator is used only as a bath circulator, it is important to know whether there is some material inside the bath, which has to be thermostated. In that case, the thermal capacity of the thermostated material has to be included.
