Abstract
本发明说明了适合于冷冻机和空调设备中作冷
冻剂的三氟甲烷和1，1，12-四氟乙烷的混合物。
Description
本发明涉及适用于冷冻机和空调设备中作冷冻剂的三氟甲烷和1，1，1，2-四氟乙烷的新混合物。
在适合于较一般的温度范围和低温范围的空调设备和冷冻机中，迄今在许多情况下使用二氟氯甲烷（＝R22）冷冻剂。由于生态学原因，使用R22冷冻剂当今已不再是受欢迎的。
因此存在着为这类冷冻机和空调设备提供合适冷冻剂的任务。
现已找到适合于作冷冻机和空调设备的冷冻剂的三氟甲烷（＝R23）和1，1，1，2-四氟乙烷（＝R134a）的混合物。
因此本发明对象是适合于冷冻机和空调设备中作冷冻剂的混合物以及这些混合物作为冷冻剂在冷冻机和空调设备中的应用。这些混合物由2至8重量%三氟甲烷（＝R23）和92至98重量%1，1，1，2-四氟乙烷（＝R134a）组成。这里特别优选的是含有4至6重量%R23的混合物。
本发明的混合物以有利的方式特别适合于作为较一般的温度范围和蒸发温度（t0）在-25℃以下的低温范围的冷冻剂，例如作为t0在-25℃至-45℃之间的温度范围的冷冻剂用于冷冻机中，例如用于低温冰箱，低温冰柜，为航空和科学目的的冷冻室，速冻食品冷冻室，食品市场的冷冻装置，大型工业冷冻设备和空调设备中。
以下实施例应更详细说明本发明，而不是把本发明限制在这些实施例范围内。
图1：一压缩机试验台的示意图（VE：压缩机，VF：用水冷却的液化器，DO：节流点，EV：膨胀阀，NI：混合管，VO：气流体积测量仪，A，B：分支点，E：进气阀）
实施例
实施例1
R23和R134a冷冻剂混合物的制备。
借助于真空泵把一个压力罐抽真空，紧接着在一个市售的低温冰柜中冷却到约-25℃。借助于一个比重计通过阀门首先将计算好的高沸点的组分R134a，紧接着将低沸点的组分R23计量加入此压力罐中，制成由95重量%R134a和5重量%R23组成的混合物。
实施例2
R23和R134a冷冻剂混合物的制冷技术特性。
为了测定致冷技术特性，用按照实施例1制成的由5重量%R23和95重量%R134a组成的冷冻剂混合物在一台已知的压缩机试验台（Copeland公司产品）上进行试验。此压缩机试验台按部份冷凝法操作并包含一循环系统，该循环系统包括通过管道互相连接的压缩机VE，液化器VF，节流点DO，入口阀E，膨胀阀EV，混合管MI，以及气流体积测量仪VO。所使用压缩机试验台的一些主要位置图示于图1中。
装有冷冻剂的压力罐和位于膨胀阀前面的抽真空的压缩机试验台的入口阀连接。为了把液态的冷冻剂转移到抽真空的冷冻设备中，再将压力罐加热到室温。紧接着在压缩机试验台上按照部份冷凝法进行确定冷冻剂制冷特性的测量。此测量按标准规范DIN8977和ISO917进行。在来自液化器VF的混合物通过膨胀阀EV再膨胀之后，此测量方法以在分支点A把离开压缩机VE的冷冻剂气流分成要液化的冷冻剂气流和节流的冷冻剂气流，在B点又相聚在一起为依据。冷冻剂的液化部份在混合管NI中蒸发并和来自节流点DO的气流混合。测量压缩机的入口温度及压力（t1h，Po）和出口温度及压力（t2h，Pc），测量实际的气流体积Veff和压缩机轴的转速。
此外，按已知方法根据等容线原理对非共沸混合物的本发明R23和R134a混合物进行p-v-T-x-测量。考虑到由p-v-T-x-测量得到的关于本发明混合物和压缩机试验台上试验结果的容积特性数据，可按已知方式通过提出焓熵图（Mollier-Diagramm）来测定或计算出本发明的冷冻剂混合物的的以下制冷技术特性：
蒸发温度（t0） -39.8至-27℃
压缩机的入口压力（P0） 1.05巴
压缩机的入口温度（t1h） 1.82℃
压缩机的出口压力（Pc） 10.60巴
压缩机的出口温度（t2h） 97.37℃
液化温度（tc） 38.5至25.6℃
冷冻剂的实际体积流量（Veff） 6.37米3/小时
制冷过程的性能指数 ηKA2.10
供给系数 λ 0.698
等熵压缩效率 ηis0.716
制冷能力 Q01.37KW
压力比 Pc/Po10.1
冷冻剂物料流量 mR29.68公斤/小时
在实验测量的基础上测得的数据证明按本发明的R23和R134a的混合物具有良好的制冷技术特性。用本发明的冷冻剂混合物在可接受的压力比的条件下可达到高制冷能力和高性能指标。
