Itheyibhile yeyunithi yokuguqulwa eqhelekileyo yefriji

Iiyunithi eziqhelekileyo kunye nokuguqulwa

1 MW = 1000千瓦

1千瓦= 1000 W

1千瓦= 861千卡/ h = 0.39便士

1 W = 1 J / s

0.1 mpa = 1公斤/平方厘米= 10米imekyuriikholam= 100 kpa

1美国贸易代表办公室= 3024千卡/ h = 3517 w(冷量)

1 BTU = 0.252千卡/ h = 1055 j

1 BTU / H = 0.252千卡/ H

1 BTU / H = 0.2931 w

1 MTU / H = 0.2931千瓦

1 HP (umbane)= 0.75千瓦。umbane)

1千瓦。umbane)= 1.34 hp (umbane)

1 RT = 3.517千瓦

1千瓦rt = 860 = 0.284千卡/ h = 3.412 mbh

1 P = 2200千卡/ h = 2.56千瓦

1千卡/ h = 1.163 w

1 W = 0.86千卡/ h

F = 9/5℃+ 32

5/9℃= (F-32)

1 CFM = 1.699 m³/ H = 0.4719 l / s

1 M³/ H = 0.5886 cfm

1 l / s = 2.119 cfm

1流量= 0.06308 l / s

张l / s = 15.85 gpm

1公斤/平方厘米= 105 = 10 mh2o = 1 = 0.1 mpa

1 Pa = 0.1 mmh2o = 0.0001 mh2o

1 mH2O = 104 pa = 10 kpa

(Ixabiso le-thermal yamalahle asemgangathweni) Hc = 8.14 * 103 w.h /公斤

1 MJ = 0.034125公斤(umgangathoamalahle)

1 Nm3。yendaloigesi)= 1.2143公斤(umgangathoamalahle)

Ulwazi oluqhelekileyo

张千卡:张公斤yokushisa kwamanzi ukunyuka okanye ukuwa kwe-1℃phantsi koxinzelelo oluqhelekileyo lwe-atmospheric, Ubushushu obufunxayo okanye obukhutshwayo yikhalori enye。

张公斤yeqhwa ifumana iikhalori ezingama - 80

Ubushushu be-vaporization ye-1公斤yamanzi yi - 539卡路里

我℃ingxinano yamanzi yeyona inkulu

我所/警察/ IPLV umthamo wokukhenkcisa / Umlinganiselo wemveliso yobushushu ukuya kumandla okufakwayo。无论何时ithetha icompressor,警察ithetha inkqubo, IPLV ithetha i-avareji enobunzima bokusebenza kakuhle kwamandla phantsi kwemithwalo eyahlukeneyo。

IPLV = 2.3% * 46.1% + 41.5% * B + * C + 10.1% * D (i-avareji yobunzima)
