Quam eligere fingunt machina temperatus

1. Speciales casus iniri necesse est:


A, potentia calefacientis seu congelatio potentiae KW = W×△t×C×S/860×T


W = fingunt pondus vel frigidam aquam KG


t= differentia temperatura inter caliditatem desideratam et siccus incipiens.


C= oleum calidum specificum (0.5), ferrum (0.11), aqua (1), plasticum (0.45~0.55)


B, magnitudinem sentinam invenire


Scire elit requiritur sentinam fluxus et pressura (caput)


P(pressura Kg/cm2)=0.1×H(caput M) ×α (gravitas specifica caloris media translationis, aqua = I, oleum = 0.7-0.9)


L(media requisita fluxus L/min)=Q(mendarum caloris postulati Kcal/H)/C(media proportio aquae calidae = olei = 0,45)t (discrimen temperaturae inter media et forma circulatio) ×α×60


2. Freezer facultatem delectu


A, Q (congelantia quantitas Kcal/H)=Q1+Q2


Q1(Caloris Kcal/H materiae rudis in forma)=W(pondus KG materiae rudis in formam per horae injectae) ×C×(T1-T2)×S(** coefficiens 1.5~2).


T1 temperies materiae rudis in tubo materiali; T2 Temperature cum operis e forma sumitur


Q2 calor generatur ex calidum cursor Kcal/H


B, methodus velox calculi (non applicabilis ad calidum cursorem)


1RT=7~8 OZ1OZ=28.3g (including ** coefficiens)


1 rt = 3024 kcal/H = 12000 btu/H = 3.751 KW


1KW=860 Kcal/H1 Kcal=3.97BTU

3, turrim aquae frigidae lectio =A+B


A,iniectio fingens machina


Turris aquae refrigerationis RT = iniectio machinae horsepower (HP)×0.75KW×860Kcal×0.4÷3024


B, freezer


Aquae refrigerandae turrim RT= freezer refrigerationem ton (HP) ×1.25
