Ora\u015ful Sion, situat \u00een cantonul elve\u0163ian Valais, este foarte activ pe plan cultural \u015fi sportiv. \u00cen fiecare an, \u00een timpul iernii, pune la dispozi\u0163ia cluburilor de hochei \u015fi patinaj, \u015fcolilor \u015fi publicului, dou\u0103 zone de ghea\u0163\u0103. \u00cen 2017, municipalitatea cere departamentului de refrigerare al Meier Tobler s\u0103 efectueze o diagnosticare a unit\u0103\u021bii de r\u0103cire utilizat\u0103 pentru a ob\u0163ine capacitatea de refrigerare necesar\u0103 celor 1.800 m\u00b2 ai patinoarului s\u0103u \u00een aer liber.<\/p>\n

Instruc\u0163iunile sunt clare: s\u0103 pun\u0103 \u00een aplicare o strategie energetic\u0103 \u015fi ecologic\u0103 de viitor pentru a face fa\u0163\u0103 provoc\u0103rii varia\u0163iilor de temperatur\u0103 din acest ora\u015f \u00eenconjurat de mun\u0163i, unde temperatura exterioar\u0103 poate atinge la \u00eenceputul sezonului 28 \u00b0C. Suprafa\u0163a \u00eenghe\u021bat\u0103 trebuie s\u0103 indice \u00een mod constant -8 \u00b0C.

\nMeier Tobler, specializat\u0103 \u00een domeniul tehnologiei de construc\u0163ii, care se afl\u0103 \u00een Elve\u0163ia de c\u00e2teva decenii, \u00eenlocuie\u015fte vechiul sistem care a folosit un refrigerant cu un GWP mai mare de 3.900 printr-un chiller cu CO2<\/sub> (GWP=1).<\/p>\n

Ini\u0163ial, lichidul de transfer termic monopropilenglicol a continuat s\u0103 curg\u0103 prin cei 94.400 metri de conducte pentru a forma covorul de ghea\u0163\u0103. \u00cen 2018, echipa tehnic\u0103 a lui Meier Tobler nu a atins performan\u0163a a\u015fteptat\u0103 \u015fi a efectuat o analiz\u0103 a lichidului de transfer termic. Aceasta a relevat o degradare a lichidului de transfer termic, probabil legat\u0103 de varia\u0163iile puternice de temperatur\u0103 suferite \u00een ultimii ani.<\/strong><\/p>\n

Cyrille Januet, Consilier de V\u00e2nz\u0103ri Refrigerare Industrial\u0103, explic\u0103: \u201e\u00cen continuitatea viziunii noastre, ne-a p\u0103rut \u201enatural\u201d s\u0103 propunem un lichid de transfer termic de origine vegetal\u0103 \u015fi cu responsabilitate ecologic\u0103. \u00centr-o \u00eent\u00e2lnire cu Climalife, John Padilla ne-a prezentat Greenway\u00ae Neo \u015fi condi\u0163iile de func\u0163ionare foarte apropiate de lichidele uzuale de transfer termic, cu avantaje semnificative, cum ar fi v\u00e2scozitatea sc\u0103zut\u0103, care ne-a permis s\u0103 reducem puterea pompelor de circula\u0163ie\u201d.<\/em><\/p>\n

\u00cen septembrie 2018, circuitul de transfer termic a fost golit, cur\u0103\u0163at \u015fi umplut cu 18.000 litri de Greenway\u00ae Neo -30<\/a>. <\/strong>De atunci, sezonul este \u00een plin\u0103 desf\u0103\u015furare, iar performan\u0163ele nu dezam\u0103gesc.
\nUnele ajust\u0103ri ale echipamentului electric au permis o reducere imediat\u0103 a consumului cu 20%. \u00cen regim stabilizat, intensit\u0103\u0163ile absorbite de pompe sunt mai mici. Capacitate de r\u0103cire cu 5 compresoare cu 5 compresoare cu piston care func\u0163ioneaz\u0103 cu CO2<\/sub> a permis o modularitate mai bun\u0103 a puterii, cu o stabilitate a COP \u00eentre 10 \u015fi 100% din sarcin\u0103.<\/p>\n
