冰(bing)(bing)(bing)(bing)(bing)浆蓄冷融冰(bing)(bing)(bing)(bing)(bing)速度快(kuai),负荷响应灵敏(min)。冰(bing)(bing)(bing)(bing)(bing)球和盘管的融冰(bing)(bing)(bing)(bing)(bing)放(fang)冷需(xu)要通(tong)过(guo)不冻液来间接传(chuan)递,这就使得融冰(bing)(bing)(bing)(bing)(bing)过(guo)程(cheng)(cheng)中(zhong)同(tong)样面临着(zhe)与制(zhi)冰(bing)(bing)(bing)(bing)(bing)过(guo)程(cheng)(cheng)中(zhong)相同(tong)的传(chuan)热热阻(zu)问题(ti)。当(dang)空调用户端(duan)冷负荷需(xu)求较(jiao)高(gao)的时(shi)候,蓄冰(bing)(bing)(bing)(bing)(bing)槽内的冷量无法(fa)快(kuai)速释放(fang) 。
