2. Zaɓin naúrar sanyaya:
1. Naúrar guda ɗaya da ɗakin ajiya guda ɗaya: ƙarfin kwantar da hankali = 1.1 × ƙarfin sanyi na ajiyar sanyi; jimlar ikon sanyaya tsarin: 1.1-1.15 mai arziki ya kamata a yi la'akari.
2. Naúrar ɗaya tare da ɗakunan ajiya masu yawa: ƙarfin sanyaya na naúrar = 1.07 × jimlar ƙarfin sanyi na ajiyar sanyi; jimlar ƙarfin sanyaya tsarin: 7% na asarar bututun ya kamata a yi la'akari.
3. Naúrar layi ɗaya tare da ɗakunan ajiya masu sanyi masu yawa: ƙarfin sanyaya naúrar = P × jimlar ƙarfin sanyi na ajiyar sanyi;
Jimlar ƙarfin sanyaya tsarin: asarar bututun bututun na 7% da ƙimar aikin sito a cikin lokaci guda yakamata a yi la'akari da shi.
Abubuwan da ake buƙata don zaɓin mai sanyaya iska:
Mai firiji;

Abubuwan da ake buƙata don zaɓin mai sanyaya iska: 1. Refrigerant: Na'urori daban-daban suna da musayar zafi daban-daban da juriya na matsa lamba. R404a yana da babban musayar zafi fiye da R22, kusan 1%. 2. Yanayin sanyi na sanyi: Ƙananan zafin ajiyar sanyi, ƙarami da musayar zafi kuma mafi girma tazarar guntu. Daidai zaɓi tazarar fin na mai sanyaya iska: jimlar;
Jimlar ƙarfin sanyaya tsarin: asarar bututun bututun na 7% da ƙimar aikin sito a cikin lokaci guda yakamata a yi la'akari da shi.
3. Musanya zafi:
Canjin zafi na mai sanyaya iska ≥ da sanyaya amfani da sanyi ajiya * 1.3 (sakamakon sanyi); musayar zafi mara kyau: musayar zafi a cikin samfurin × ainihin ƙima; musayar zafi a ƙarƙashin yanayin ƙira: musayar ƙima Heat × gyare-gyare coefficient; Matsakaicin gyare-gyaren zafin jiki na ajiya: ƙananan zazzabi na ajiyar sanyi, ƙarami na musayar zafi. Fin abu gyara factor: abu da kauri. Matsakaicin gyaran gyare-gyare na fin rufin fin: murfin anti-lalata yana rage musayar zafi; Coefficient na gyaran ƙarar iska: buƙatun musamman don fan.
4. Tsarin mai sanyaya iska Nau'in Rufi:yawanci ana amfani dashi a cikin ajiyar sanyi;
nau'in rufi: tashar iska biyu, tashar iska guda hudu, kwandishan;
nau'in bene: ɗakin daskarewa mai sauri, ko firiji mai bututun iska.
.Gwargwadon ajiyar sanyi, nisan samar da iska, da girman ajiyar sanyi, a ko'ina busa iska, da ƙayyade adadin masu sanyaya.
5. Zaɓin hanyar defrosting na ajiyar sanyi:
