                冷冻库的匹配问题

                查看次数:25 发布时间:2019/11/12 10:19:32


                一、选♀配冷风机,每立方米按W0=70W/m3计算
                 
                  1、若V(冷库容积)<30m3,开门次数较频繁的冷库,如鲜肉库,则乘系数A=1.2
                 
                  2、若30m3≤V<100m3,开门次数较频繁的冷库如鲜肉库,则乘系数A=1.13
                 
                  3、若V≥100m3,开门次数较频繁的冷库,如鲜肉库,则乘系数A=1.0
                 
                  4、若为单个冷冻库时,则乘系数B=1.1最终冷风卐机选配按W=A*B*W0(W为冷风机热负荷)
                 
                二、当冷库与低温柜共用机组时,机组及冷风机匹※配按-35℃蒸发温度计算。当冷库与低温柜分开时,机组及冷风机匹配按-30℃蒸发温度计算加工间负荷匹配
                 
                  1、选配冷※风机,每m3按W0=110W/m3计算,(1)若V(加工间容积)<50m3,则乘系数A=1.1(2)若V≥50m3,则乘系数A=1.0最终冷风机选配按W=A*W0(W为冷风机热负荷)
                 
                  2、选配机组,每立方米按Q0=55W/m3计算,(1)若V(加工间容积)<50m3,则乘系数A=1.1(2)若V≥50m3,则乘系数A=1.0最终机组选配按Q=A*Q0(Q为机组制冷能力)
                 
                三、当加工间与中温柜共用机组时【,机组及冷风机匹配按-10℃蒸发温度计算。当加工间与中温柜分开时,机组及冷风机匹配按0℃蒸发温度计算。
