Cooling Tower Outlet Tui Temperature hi Engtiang chiahin nge a tlahniam theih?

Cooling tower-a cooling limit hnuhnung ber chu local outdoor wet-bulb temperature atanga teh a ni a, lehinfinite cooling a awm thei lo. Core industry consensus chu hetiang hi a ni: standard open cooling tower-a outlet water temperature tlem ber chuan outdoor wet-bulb temperature plus 3 to 5℃chauh a hnaih thei a ni.

 

A heat exchange structure-in a tihkhawtlai a, .cooling tower khar a ni a temperature hnuhnung ber chu℃2 atanga 4 in a tihsan belh dawn a ni . Tui lumna hniam zawk mamawh a nih chuan chiller, ice thermal storage system emaw refrigeration hmanrua dang emaw dah a ngai a ni.

 

 

 

Outdoor wet-bulb temperature hi air moisture content leh heat dissipation capacity tehna atana parameter pawimawh tak a ni a, miten dry-bulb temperature an hriat tlangpui aiin a danglam hle.

 

 

 

Summer ni sweltering, air humidity sang takah chuan wet-bulb temperature hian ambient temperature a hnaih a, cooling tower-a heat rejection performance nasa takin a tichak lo hle.

 

 

 

Hmun vawt leh boruak \\ha-bulb temperature hniamna hmunah chuan heat dissipation efficiency chu mak tak maiin a \\ha chho \\hin. North China-a summer operating conditions entirnan la ila: dry-bulb temperature 35℃leh wet-bulb temperature 27℃a nih chuan, open cooling tower pangngaia theoretical minimum outlet temperature chu 30℃atanga 32℃inkar a ni.

 

 

China ram vawt takah chuan dry-bulb temperature chuan 38℃a thlen laiin wet-bulb temperature chu 22℃chauh a ni a, outlet water chu 25℃–27℃thlengin a lum thei a, hei hian temperature danglamna chiang tak a lantir a ni.

 

 

 

 

Open counter-flow lehcross-flow cooling towers te chu a awm amodel hman lar berte an ni. Heat dissipation atan tui leh boruak inkara direct contact evaporation an rinchhan a, heat exchange efficiency sang ber leh cooling limit tha ber an pe chhuak thin.

 

 

 

Ideal full-load condition-ah chuan fill thianghlim, fans full speed-a kal leh uniform water spraying hnuaiah chuan theoretical cooling limit chu wet-bulb temperature aiin℃3 a sang a ni.

 

 

 

 

Practical engineering application-ah chuan fills-a scaling, fan air volume tihtlem, tui insem dan inang lo leh tower chhunga air short-circuiting te hian performance hlohna a siam a ni.

Hei hian air compressor, injection molding machine leh medium-frequency furnace-a high-temperature equipment-ah te operating temperature sang lutuk leh overheating alarm a thlen thin.

 

 

 

 

Closed cooling towers hian sealed coil heat exchange an hmang a, chuvangin circulating cooling water hian boruak nen direct contact a nei ngai lo va, tui quality thianghlim, bawlhhlawh-free a vawng reng thin. Tui quality mamawh khauh tak nei scenario-ah an inmil a, chung zingah chuan photovoltaic energy storage, precision machine tools leh chemical reactor te pawh a tel.

 

 

Mahse, metal coil wall atanga extra thermal resistance chuan open tower nena khaikhin chuan an cooling capacity a ti tlem zawk a ni. Wet-bulb condition inang chiah hnuaiah chuan closed tower outlet temperature chu open tower aiin 2–4℃in a sang zawk a ni.

 

Bulb temperature 27℃wet-na hmunah chuan standard closed cooling tower chuan outlet temperature tlem ber 32℃–34℃chauh a thleng thei a ni. Auxiliary spray cooling dah belh leh fan airflow tihpun hian temperature gap chu roughly 1℃in a tihtlem thei a, chutih rualin open cooling tower-a cooling limit nen a la inmil thei lo.

 

 

User tam tak chuan low-temperature cooling water an mamawh a, entirnan, thlasik laiin 15℃atanga 20℃vel, cooling tower chauh hmanga tih theih a ni lo.

 

Thlasik laiin boruak lumna tlahniam mah se, boruak hian fundamental wet-bulb temperature threshold a la nei a, evaporation cooling chauh hian he threshold hnuai lam tui hi a ti lum thei lo.
