Unverified容积并非越大越省电：大容积冰箱空转能耗更高，按每人60-80L计算，三口之家400-450L足够，盲目买600L以上会导致长期空载耗电浪费78% similarUnverified3-4口之家选5L容量，2人以下选4L，5人以上选6L；电压力锅实际可用容积约为标称的70%（因需留膨胀空间），故不宜买过小77% similarUnverified新风量选择按人均30m³/h计算，再乘以1.3~1.5的余量系数。三口之家日常需选90~135m³/h机型，若房屋密闭性差或有明火厨房需选150m³/h以上77% similarUnverified单相居民表选5(60)A规格，即基本电流5A、最大60A，可满足12kW以内负荷；若家装中央空调或电动车充电桩，需选10(100)A规格避免过载烧表75% similarUnverified居民户内单相计量选5(60)A或10(60)A规格，标称电流5A/10A、最大60A即可覆盖6-12kW总负荷；带电动汽车充电桩需选10(100)A或直接上三相表73% similar
