THE STUDY FUNCTIONING FLOOR CONVECTOR

Eng.Marian Cristian RAICU1,

Rezumat. Lucrarea pune in evidenta una dintre noile metode inovative de incalzire a incintelor, in contextul reducerii consumului de energie si a evidentieri unor echipamente care pot inlocui cu succes echipamentele clasice de incalzire,in spatii mai pretentioase si mai putin accesibile.Articolul se focuseaza pe studiu functionarii unor componente importante a acestui echipament si anume schimbatorul de cadura, si ventilatorul, care implica etalarea anumitor performante: incalzirea in timpi redusi,cu mentinearea caldurii,pentru o perioada de timp, nivel de zogmot redus, desi materialul din care sunt facute aceste componente sunt rezistente in timp,si prezinta o calitate ridicata.Echipamentul este ideal in crearea unui confort termic optim atat in spatiile vitrate, malluri, resturante, scolii , spitale sau saune.Mai putem mentiona ca convectroul de pardoseala pote fi utilizat concomintent si cu alte echipamente de incalzire convetionale , fara a crea perturbatii, in cazul unei functionarii comune.

Abstract. The paper highlights one of the new innovative methods of heating the premises, in the context of reducing energy consumption and highlighting some equipment that can successfully replace conventional heating equipment in areas most demanding and less accessible. The article focuses on the trial operation of major components of this equipment, namely heat exchanger and fan, which involves the display of certain performance: heating in reduced time, maintaining the heat for a while, low noise, although material which are done while these components are resistant, and features a high quality. The device is ideal in creating an optimal thermal comfort in both windowed spaces, malls, restaurants, schools, hospitals, or saunas. We can mention that the floor convector can be used concomitantly with other conventional heating equipment without creating disturbances, in the case of a joint operation

Keywords: floor convector, heating equipment, thermal comfort, energy efficiency, low noise level

1. Thermal comfort and air quality

Atunci cand vorbim de confort termic facem referie la acea senzatie de comoditate pe care o simte organismul uman , fara a percepe modificarii bruste ale temepraturii, atunci cand are loc schimbul de caldura intre acesta si mediu inconjurator.Pentru acesta s-au facut, si se fac in continuare eforturi pentru a crea echipamente de climatizare cu un conusm de redus de energie, cu o eficienta

ridicata, si care sa raspunda ,,usor” noilor tendinte tehnologice cerute de piata si de zona in care acesta sunt ,,impuse”, sau exploatate. Pentru a mentine un confort termic intr-o incapere, trebuie sa tina cont de anumiti parametri :temperatura , umiditatate, gradul de poluare, si luminozitate, landu-se in calcul destinatia incaperii.Cat despre calitatea aerului intr-o incapere fie ea in spatii rezidentiale sau industriale , trebuie sa se tine cont de sistemul de ventilatie atasat incaperii, astfel acesta trebuie sa raspunda cerintei utilizatorului si sa functioneze conform normelor ,,CE” si sa acopere necesarul de aer curat coprespunzator zonei de locuit.Printre altele echipamenul abordat in acesta lucrare , mai indeplineste si rolul de ventilare (dupa caz) a aerului din incapere, utilizandu-le la realizarea convectiei fortate, mai precis , prin spalarea schimabatorului de caldura cu aer se realizaeaza incalizirea acestuia .

For writing equations, use Math Type or Equation Editor; don’t forget impose the format for each category (the same as for the main text: font Times New Roman, size 12).

2.1. Subsection header (for new subsection header, select this row and use Format Painter for the new text, in the appropriate position)

The sub section paragraphs have the same formatting: Font Times New Roman, regular, size 12; line spacing options: 0 points before and 6 points after the paragraph.

For inserting figures follow the instructions below the figures.

For citing figures, use: see Figure 1, b.

Fig. 1 For a new figure, copy Fig. 1. at the left of this row and paste in the desired position.a. Description; b. Description.

For a new equation don’t forget: after copying, press CTRL+A (=select all) then F9 key for the field be actualized.

2.2. Second subsection header

The first paragraph for the second subsection (same formatting).

In a table you may insert images and equations if necessary, but the text must be legible.

The formula must have font size 10 points.
