ALIMENTARE CU ENERGIE A SEREI INDUSTRIALE CU UTILIZARE A POMPEI DE C LDUR CU AC IONARE DE GAZ , partea II

Şit M.L., Ioişer A.A., Andronati N.R., Burciu V.I., Şit B.M. Institutul de Energetic al Academiei de Ştiin e a Moldovei

Rezumat. În articol este propus schema leg turii schimb torului de c ldur pentru utilizarea c ldurii gazelor eşapate cu evaporator. În schema propus se asigur valoarea minim a puterii ventilatorului pentru transmiterea aerului pe evaporatorul pompei de c ldur şi compensarea pulsaţiilor temperaturii gazelor eşapate şi presiunii ventilatorului. Este demonstrat cum se poate de optimizat parametrii schimb torului de c ldur din condiţia minimului disip rii energiei cu utilizarea valorii ce se numeşte entransia. Este elaborat schema sistemului coordonat de dirijare a transmisiilor hidraulice, ce transmit puterea pe compresorul pompei de c ldur şi pe generatorul electric.

Cuvinte-cheie: Sistemul de dirijare, dioxid de carbon, pompa de c ldur , recuperator de c ldur , entransie.

Abstract. In this article a scheme of connection of heat exchanger for utilization of heat of flue gases with vapor source is proposed. In proposed scheme is represented minimum power of ventilator for air’s feeding on the vapor source of heat pump and compensation of pulsation of temperature of flue gases and pressure of ventilator. It is shown how to optimize parameters of heat exchanger in conditions of minimum of dissipation of energy with utilization of value of entransy. It is elaborated a scheme of coordinated control system of hydraulic transmissions, that transfers power on compressor of heat pump and electrical generator.

Keywords: Heat pump, recuperator, coordinated control system, carbon dioxide, entransy.
