摘　　要：中央厨房在熟化餐饮、冷冻餐饮和制冷空间中产生大量的热能,但目前回收率低。为了高效利用这些热量,不让其排放到室外,造成能源浪费,增加温室气体排放,通过对比分析热能回收的常见办法,分析水管里的水热能交换的过程,构建了热量回收的数学模型,获得回收热能产生的热水。利用热能回收的热水可二次利用,用于淋浴、清洗等,使热能得到有效的利用,减少能源消耗。结合中央厨房的整体格局,提出中央厨房热管换热式能量回收系统的布局,使水管里的水从热能制造源流向热源回收源,在泵和单向节流阀的作用下,流向热水箱,实现水的闭环流动。以某一个餐饮生产量为2万份/8 h的中央厨房为例,建立热能式热能回收系统,每天至少节约1190 k W·h的电能。The central kitchen produces a lot of heat energy while cooking,frizzing and refrigerating,but the heat energy is minimum recoveryrate.The purpose is to make efficient of the heat,discharged outdoors,what will cause energy waste and increase greenhouse gas emissions.Combined with the overall pattern of the central kitchen,the common methods of heat recovery were compared and analyzed.Through theanalysis of heat exchange process in the heat pipe,the mathematical model of heat recovery was established,and the total hot water generatedby heat recovery was obtained.Using the hot water for bathing and cleaning,so that the thermal energy could be effectively used and the energyconsumption could be reduced.The layout of the heat recovery system of the central kitchen with the heat pipe was proposed,which made thewater pipe of the heat recovery system flow from the hot water tank to the heat source to recover heat energy.Finally,under the action of thepump and one-way throttle valve,it flowed to the hot water tank to realize the closed-loop flow of water.Taking a central kitchen which canproduce 20000 portions meals every 8 hours as an example,at least 1190 k W·h of electric energy can be saved every day by establishing aheat recovery system.
