Sezvo kupisa kukuru kunoparadza United States, Europe neAfrica, kuchiuraya zviuru, masayendisiti anonyevera kuti kwakaipisisa kuchiri kuuya.Nenyika dziri kuramba dzichipomba magasi egreenhouse mumhepo uye mukana wemutemo une revo wekushanduka kwemamiriro ekunze uri kuputsika muUS, tembiricha iri muzhizha rino ingaite kunge yakapfava mumakore makumi matatu.

Vhiki rino, vazhinji vakaona kuuraya kunopisa kwakanyanya kunogona kuita munyika isina kugadzirira kupisa kunopisa.MuUK, uko mhepo inofefetera isingawanzo, zvifambiso zvevoruzhinji zvakavharwa, zvikoro nemahofisi zvakavharwa, uye zvipatara zvakadzima maitiro asiri echimbichimbi.

Air conditioning, tekinoroji inotorwa sechinhu nevakawanda munyika dzakapfuma kwazvo, chishandiso chinoponesa upenyu panguva yekupisa kwakanyanya.Zvakadaro, chikamu chisere chete kubva muzana chevanhu bhiriyoni 2.8 vanogara munzvimbo dzinopisa zvikuru - uye kazhinji dzine urombo -- nzvimbo dzenyika parizvino dzine AC mudzimba dzavo.

Mune bepa richangoburwa, boka revatsvakurudzi kubva kuHarvard China Project, yaigara paHarvard John A. Paulson School of Engineering and Applied Sciences (SEAS), yakaenzanisira kudiwa kwemangwana kwemhepo inotonhorera semazuva ane kupisa kwakanyanya kuwedzera pasi rose.Chikwata ichi chakawana mukaha mukuru pakati peazvino AC kugona uye chii chichazodiwa ne2050 kuchengetedza hupenyu, kunyanya munyika dzine mari shoma uye dzichiri kusimukira.

Vatsvakurudzi vakafungidzira kuti, paavhareji, 70% yevanhu vari munyika dzakawanda vachada air conditioning panosvika 2050 kana mwero wekubuda kwemhepo ukaramba uchiwedzera, uye nhamba iyoyo yakatokwira munyika dze equatorial seIndia neIndonesia.Kunyangwe pasi rose rikasangana nezvisungo zvekuburitsa hutsi zvakatarwa muParis Climate Accords - izvo zvisiri mugwara rekuita - pakati pe40% kusvika 50% yehuwandu hwevanhu munyika dzakawanda dzinodziya pasi rose zvichange zvichiri kuda AC.

"Zvisinei nematanho ekuburitsa, panofanirwa kuve nekukwira kukuru kwemhepo yekufefetera kana imwe nzira yekutonhodza nzvimbo yemabhiriyoni evanhu kuitira kuti vasave pasi pekupisa kwakanyanya uku kwehupenyu hwavo hwese," akadaro Peter Sherman. , mumwe postdoctoral shamwari paHarvard China Project uye munyori wekutanga webepa richangoburwa.

Sherman, ane postdoctoral shamwari Haiyang Lin, naMichael McElroy, Gilbert Butler Purofesa weEnvironmental Science kuSEAS, vakatarisa chaizvo mazuva apo musanganiswa wekupisa nehunyoro, wakayerwa neinonzi tembiricha yegirobhu yakareruka, yaigona kuuraya kunyangwe mudiki. , vanhu vane utano hwakanaka mumaawa mashomanana.Zviitiko izvi zvakanyanyisa zvinogona kuitika kana tembiricha dzakwira zvakakwana kana kuti mwando wakakwira zvekudzivirira dikita kutonhodza muviri.

"Ipo isu takatarisa pamazuva apo tembiricha yakarerutswa yegirobhu yakapfuura chikumbaridzo icho tembiricha iri kuisa hupenyu hwevanhu vazhinji, tembiricha yegirobhu iri pazasi pechikumbaridzo ichi inogona kunge ichiri kusagadzikana uye nengozi zvekuda AC, kunyanya kune vanhu vari munjodzi. ,” akadaro Sherman."Saka, uku kungangove kushomeka kuti ingani vanhu veAC vachada mune ramangwana."

Chikwata chakatarisa maremangwana maviri - imwe umo kuburitswa kwemagasi egreenhouse kunowedzera zvakanyanya kubva paavhareji yanhasi uye yepakati-ye-nzira ramangwana apo kuburitswa kunoderedzwa kumashure asi kusachekwa zvachose.
 
Mune ramangwana-yakakwira-emissions, timu yekutsvagisa yakafungidzira kuti 99% yevagari vemumaguta muIndia neIndonesia inoda mhepo inofefetera.MuGermany, nyika ine mamiriro ekunze akadzikama, vaongorori vakafungidzira kuti inosvika 92% yehuwandu ichada AC kune zviitiko zvekupisa zvakanyanya.MuUS, vangangoita 96% yevagari vachada AC.
 
Nyika dzine mari yakawanda seUS dzakagadzirira zvirinani kune ramangwana rakashata.Parizvino, vamwe 90% yevagari vemuUS vane mukana weAC, zvichienzaniswa ne9% muIndonesia uye 5% chete muIndia.
 
Kunyangwe kana kuburitswa kwakaderedzwa kumashure, India neIndonesia zvicharamba zvichidikanwa kuendesa mhepo yekufefetera 92% uye 96% yehuwandu hwemaguta avo, zvichiteerana.
 
Yakawanda AC inoda simba rakawanda.Mafungu ekupisa kwakanyanya ave kutonetsa magidhi emagetsi pasi rose uye kuwedzera kukuru kwekuda kweAC kunogona kusundira masisitimu azvino kusvika pakupwanya.MuUS, semuenzaniso, mhepo inofefetera inotova inodarika makumi manomwe muzana epamusoro pekugara kwemagetsi kudiwa pamazuva anopisa zvakanyanya mune dzimwe nyika.
 
"Kana iwe ukawedzera kudiwa kwe AC, izvo zvine simba guru pane grid yemagetsi zvakare," akadaro Sherman."Inoisa dambudziko pagridi nekuti munhu wese achashandisa AC panguva imwe chete, zvichikanganisa kudiwa kwemagetsi."
 
“Pakuronga magadzirirwo emagetsi enguva yemberi, zviri pachena kuti haugone kungowedzera kudiwa kwemazuva ano, kunyanya kunyika dzakaita seIndia neIndonesia,” akadaro McElroy."Matekinoroji akadai sesimba rezuva anogona kunyanya kubatsira pakubata matambudziko aya, sezvo curve yemagetsi inoenderana inofanirwa kuenderana nenguva dzezhizha dzinodiwa zvakanyanya."
 
Mamwe mazano ekuenzanisa kuwedzera kudiwa kwemagetsi anosanganisira dehumidifiers, anoshandisa simba rakaderera pane air conditioning.Chero zvingagadziriswa, zviri pachena kuti kupisa kwakanyanya haisi nyaya yezvizvarwa zvinotevera.
 
"Iri idambudziko izvozvi," akadaro Sherman.
