Mafunde a kutentha achuluka kwambiri, achuluka kwambiri, ndipo amatenga nthawi yaitali chifukwa cha kusintha kwa nyengo komwe kumachitika chifukwa cha anthu.Nduna ya Zachilengedwe ku Germany Steffi Lemke adati vuto la nyengo likupangitsa kuti dzikolo liganizirenso za kukonzekera kwake nyengo yotentha kwambiri, chilala komanso kusefukira kwamadzi.
Gironde, dera lodziwika bwino la alendo kumwera chakumadzulo kwa France, lakhudzidwa kwambiri ndi moto wa nkhalango, ndipo ozimitsa moto ochokera kudera lonse la France adayesetsa kuthana ndi moto womwe unawononga nkhalango yopitilira 50,000 mu Julayi.Pamene mphepoyi inkafika kumpoto ndi kum’maŵa, anthu mazanamazana anachoka m’nyumba zawo kumpoto chakumadzulo kwa Brittany, France, chifukwa cha moto wa nkhalango.
Ku Spain ndi Portugal, anthu opitilira 1,000 afa chifukwa cha kutentha mu Julayi.Kutentha ku Portugal kugunda 47ºC, mbiri ya Julayi.Ambiri a dzikolo ali pachiopsezo cha moto ndi ofesi ya National Meteorological Office IPMA.
Olosera zam'tsogolo ku Italy adachenjeza za kutentha komwe kumakhala 40 mpaka 42ºC mkati mwa sabata lachitatu la Julayi.
Zotsatira zakusintha kwanyengo ku Europe zidawonekera koyambirira kwa mwezi uno pomwe madzi oundana osungunuka adayambitsa chigumukire chomwe chidapha anthu 11.Tsopano akatswiri a ku Italy iLMeteo akuchenjeza kuti ming'alu yatsopano ikutseguka pamwamba pa nsonga za Alpine komanso kuti ayezi akusungunuka ngakhale paphiri lalitali kwambiri ku Western Europe, Mont Blanc.

Mitengo ya Copper Yatsika ndi 20% mu Julayi
Kukwera kwamitengo yazinthu zopangira, zomwe zapitilira kuyambira theka lachiwiri la 2020, zayamba kutsika.
Malingana ndi ziwerengero zomwe zatulutsidwa posachedwapa, atatha kukumana ndi kukula kwakukulu, mitengo yamkuwa yayamba kutsika ndi kutsika kwa 20% kuyambira pakati pa June.Mu July, kuyerekeza ndi malo apamwamba kwambiri mu June kunasonyeza kuti mitengo yamkuwa yatsika kufika pa RMB 60,000 (pafupifupi US$ 9,000) pa July 6, zomwe zikuwonetsa mbiri yotsika kuyambira November, 2020. Chifukwa cha zinthu zambiri m'mayiko otukuka, monga kugwa. Purchasing Managers 'Index (PMI), kuchepa kwa ntchito zamafakitale komanso kuchita mwaulesi pamakampani opanga zinthu, msika uli ndi chiyembekezo chamtsogolo.Kutsika kwamitengo ya zinthu zopangira zinthu zambiri kwabweretsa uthenga wabwino kwa opanga ma air conditioner okhudza kuwongolera mtengo.Komabe, kufunikira kwa msika kwakhalabe kotsika ndipo kukwera mtengo sikunayang'anitsidwe bwino.Choncho, n’zokayikitsa kuti mitengo ya air conditioner idzatsika posachedwa.
Compressor Standard ya HPWHs Itha Kutulutsidwa Chaka chino
Pofuna kuthana ndi zofuna zachitukuko pamakampani otenthetsera madzi otentha (HPWH) ku China, Komiti Yachigawo ya National Home Appliances Standardization Technology Committee Residential Home Appliances Key Components idatsogolera pakukonzanso muyezo wa 'Hermetic Motor-compressors for Household and Zowotchera Zofananira Zogwiritsa Ntchito Pampu Yamadzi' zafupikitsidwa kukhala 'Heat Pump Water Heater Compressor New Standard'.
Kusintha kwakukulu pakuwunikiridwaku ndikukhudzana ndi kuchuluka kwa ntchito, ndikuwonjezera zofunikira zaukadaulo za R32, R290 refrigerants, inverter products and low low outdoor air-to-water (ATW) HPWH.M’zaka zingapo zapitazi, mafiriji a kompresa awona kuloŵedwa m’malo mofulumira m’maiko monga United States ndi Japan amene atenga mafiriji a R32, ndi maiko monga China ndi Ulaya amene atenga R32 ndi R290, zonsezo zapangidwa m’magulu akuluakulu. , ndipo msika wa inverter compressor ukuwona gawo likukwera.Komabe, mulingo womwe ulipo wa HPWH unagwiritsa ntchito ma compressor, GB/T29780-2013 'Hermetic Motor-compressor for Household and Similar Application Heat Pump Water Heater' sunapange malamulo aliwonse pazofunikira zaukadaulo za R32 ndi R290 compressor kapena inverter compressor, kupanga ma compressor. zamitundu yofananira zomwe sizingawunikidwe, zomwe sizinali bwino pakulankhulana kwaukadaulo pakati pa mabizinesi amakampani, komanso kuwunika kwamagulu azinthu.
Chifukwa chake, mulingo wowunikiridwawo wakulitsa kuchuluka kwa ntchito kwa HPWH kuyika ma compressor a hermetic motor kuti azikhala ndi ntchito zofananira ndi R410A, R134a, R417A, R407C, R32, R290, ndi R22 refrigerants.
