Abstract
BACKGROUND: Systems with chillers and fan coil units are widely used in air conditioning. Therefore, entropy-statistical analysis of energy losses in a duct-type two-pipe fan coil unit with controlled air flow is relevant.
AIM: This work aimed to review a method for determining losses by using the entropy-statistical method and to calculate losses due to non-ideal heat transfer and hydraulic losses in fan coil units.
MATERIALS AND METHODS: Losses were determined using the entropy-statistical method.
RESULTS: A comparative analysis of the results was performed. Diagrams of the distribution of loss components and recommendations for their reduction are presented.
