dispositivo de recuperação de calor, sistema termico e método para a recuperação de calor

摘要

This heat recovery device is of the type comprising a vat for holding wastewater and a heat exchanger comprising at least one heat exchange plate comprising two opposite faces and an inner pipe for circulation of a heat transfer fluid between the two surfaces. According to one aspect of the invention, the or each plate is arranged in a heat exchange compartment of the vat so that the wastewater circulates substantially vertically from bottom upwards along the two opposite faces of the or each plate between an inlet of the heat exchange compartment located in the lower portion and an outlet of the heat exchange compartment located in the upper portion. Application to thermal systems with heat pump.
