Technical field
本发明属于空调领域， 具体而言， 本发明涉及空调系统。 背景技术  The present invention is in the field of air conditioning, and in particular, the present invention relates to an air conditioning system. Background technique
R22制冷剂已被"蒙特利尔议定 "书列为限期逐步淘汰的制冷剂。 欧洲、 日本早已开始转 向 R410A制冷剂替代， 美国也将于 2010年禁止 R22在新的制冷产品中使用。 中国也加快 了 R22淘汰的步伐， 将于 2013年冻结在 2009〜2010年的平均水平， 2015年要达到削减基 线水平的 10%的要求。 而国内一些主要品牌也开始推出 R410A作为制冷剂的环保空调。 然 而 R410A的 GWP值比 R22还大， "京都议定书 "已将 R410A列为受控排放的温室效应气体， 所有 R410A 绝不是长远的替代方案。 碳氢制冷剂凭借着其有效的环境友好性 （ODP=0， GWP=3 ) 以及优良的物理性质而最为业界关注。  R22 refrigerant has been listed in the Montreal Protocol as a phase-out refrigerant. Europe and Japan have already begun to switch to R410A refrigerant replacement, and the US will also ban R22 from being used in new refrigeration products in 2010. China has also accelerated the pace of R22 phase-out, which will freeze its average in 2009-2010 in 2013 and 10% in the baseline level in 2015. Some major domestic brands have also begun to introduce R410A as an environmentally friendly air conditioner for refrigerants. However, R410A has a larger GWP than R22. The Kyoto Protocol has listed R410A as a controlled emission greenhouse gas, and all R410A is by no means a long-term alternative. Hydrocarbon refrigerants are the industry's most concerned by their effective environmental friendliness (ODP=0, GWP=3) and excellent physical properties.
但在开发研究中发现， 碳氢制冷剂用于以膨胀阀作为节流机构的冷暖房间空调器系统， 在环境温度低于 o°c时， 压缩机启动， 或者"除霜"运行完成后， 压缩机再启动时， 发生空调 系统不能正常工作， 主要表现为功率异常低下， 工作压力也异常低下。 这种异常的状况， 可以持续三四十分钟， 之后就导致压缩机内部过热， 使得压缩机电机烧损， 压缩机构磨损 而卡死。  However, in the development research, it was found that the hydrocarbon refrigerant is used in the air-conditioning system of the heating and cooling room with the expansion valve as the throttle mechanism. When the ambient temperature is lower than o °c, the compressor starts, or after the "defrost" operation is completed, When the compressor is restarted, the air conditioning system does not work properly. The main performance is that the power is abnormally low and the working pressure is abnormally low. This abnormal condition can last for thirty or forty minutes, and then the inside of the compressor is overheated, causing the compressor motor to burn out and the compression mechanism to wear and get stuck.
因此， 现有的空调系统还有待进一步改进。 发明内容  Therefore, the existing air conditioning system has yet to be further improved. Summary of the invention

本发明的发明人发现现有的空调系统经常会出现压缩机所用的冷冻机油在空调器工作 时，会被带到空调器的内部管道中，包括膨胀阀中。而在低温状态下空调器启动， 以及在 "除 霜"运行完成后， 压缩机再启动时， 膨胀阀的阀芯通路会存有一定量的冷冻机油。 而且此时 的温度非常低， 使得存在膨胀阀内的冷冻机油的粘度增大， 最终堵塞了膨胀阀。 使得空调 系统中的制冷剂流量异常低下从而引起一系列的异常状况发生， 严重影响了空调系统的可 靠性。  The inventors of the present invention have found that existing air conditioning systems often have refrigeration oils for use in compressors that are carried into the internal piping of the air conditioner, including the expansion valve, when the air conditioner is in operation. When the air conditioner is started at a low temperature, and after the "defrost" operation is completed, when the compressor is restarted, a certain amount of refrigerating machine oil is stored in the spool passage of the expansion valve. Moreover, the temperature at this time is extremely low, so that the viscosity of the refrigerating machine oil in the expansion valve is increased, and eventually the expansion valve is blocked. The abnormal flow rate of the refrigerant in the air conditioning system causes a series of abnormal conditions to occur, which seriously affects the reliability of the air conditioning system.
为此，根据本发明的一个方面，本发明提出了一种空调系统，根据本发明的具体实施例， 本发明的空调系统包含旋转式压缩机、 室内换热器、 室外换热器和节流机构， 节流机构设 置在室内换热器和室外换热器之间， 旋转式压缩机分别与室内换热器和室外换热器相连， 其中， 节流机构由膨胀阀和 /或毛细管组成。 因此本发明的空调系统为单冷空调系统。 根据本发明的具体实施例， 膨胀阀在最大开度时， 膨胀阀的内部最小流通面积不大于 9mm2, 毛细管的内部流通面积不大于 9mm2; 其流通面积相对较小， 比较容易堵塞。 因此 如果防止堵塞膨胀阀和毛细管， 避免造成空调系统故障， 那么对旋转式压缩机内的润滑油 的要求会更高。 To this end, according to an aspect of the present invention, the present invention provides an air conditioning system including a rotary compressor, an indoor heat exchanger, an outdoor heat exchanger, and a throttling according to an embodiment of the present invention The mechanism, the throttle mechanism is disposed between the indoor heat exchanger and the outdoor heat exchanger, and the rotary compressor is respectively connected to the indoor heat exchanger and the outdoor heat exchanger, wherein the throttle mechanism is composed of an expansion valve and/or a capillary tube. Therefore, the air conditioning system of the present invention is a single cooling air conditioning system. According to a specific embodiment of the present invention, when the expansion valve is at the maximum opening degree, the inner minimum flow area of the expansion valve is not more than 9 mm 2 , and the inner flow area of the capillary is not more than 9 mm 2 ; the flow area is relatively small and is relatively easy to block. Therefore, if the expansion valve and the capillary are prevented from being clogged and the air conditioning system is prevented from malfunctioning, the requirement for the lubricating oil in the rotary compressor will be higher.
因此，根据本发明的具体实施例，上述空调系统中的旋转式压缩机内具有碳氢制冷剂和 冷冻机油， 碳氢制冷剂和冷冻机油构成组合物， 组合物满足下列条件：  Therefore, according to a specific embodiment of the present invention, the rotary compressor in the above air conditioning system has a hydrocarbon refrigerant and a refrigerating machine oil, and the hydrocarbon refrigerant and the refrigerating machine oil constitute a composition, and the composition satisfies the following conditions:
在 0摄氏度的温度和 -0.05MPa的压力下， 所述组合物的粘度为不大于 1100mm2/s; 在 -10摄氏度的温度和 -0.05MPa的压力下， 所述组合物的粘度为不大于 1800mm2/s; 在 -15摄氏度的温度和 -0.05MPa的压力下， 所述组合物的粘度为不大于 2500mm2/s; 在 -20摄氏度的温度和 -0.05MPa的压力下， 所述组合物的粘度为不大于 4200mm2/s; 在 -30摄氏度的温度和 -0.05MPa的压力下， 所述组合物的粘度为不大于 11000mm2/s; 在 -35摄氏度的温度和 -0.05MPa的压力下， 所述组合物的粘度为不大于 15000mm2/s; 在 -40摄氏度的温度和 -0.05MPa的压力下， 所述组合物的粘度为不大于 20000mm2/s; 在 -50摄氏度的温度和 -0.05MPa的压力下， 所述组合物的粘度为不大于 25000mm2/s。 由此采用满足上述条件的碳氢制冷剂和冷冻机油的组合物可以有效提高旋转式压缩机 的工作能效， 更重要的是采用上述组合物可以有效避免冷冻机油被带入节流机构后堵塞膨 胀阀或者毛细管， 从而有效地提高了空调系统的可靠性。 根据本发明的具体实施例， 由于 上述组合物即使在 -50摄氏度的低温条件下，其粘度也不会超过 25000mm2/s，故不会堵塞节 流机构， 碳氢制冷剂可以保持正常流量， 旋转式压缩机可以正常运行。 因此， 采用具有上 述性能的包含碳氢制冷剂和冷冻机油的组合物可以显著提高空调系统的稳定性。 The viscosity of the composition is not more than 1100 mm 2 /s at a temperature of 0 ° C and a pressure of -0.05 MPa ; at a temperature of -10 ° C and a pressure of -0.05 MPa, the viscosity of the composition is not more than 1800 mm 2 /s ; at a temperature of -15 ° C and a pressure of -0.05 MPa, the viscosity of the composition is not more than 2500 mm 2 /s ; at a temperature of -20 ° C and a pressure of -0.05 MPa, the combination The viscosity of the substance is not more than 4200 mm 2 /s ; at a temperature of -30 ° C and a pressure of -0.05 MPa, the viscosity of the composition is not more than 11000 mm 2 /s ; at a temperature of -35 ° C and -0.05 MPa under pressure, the viscosity of the composition is no greater than 15000mm 2 / s; at a temperature of -40 degrees Celsius and a pressure of -0.05MPa, the viscosity of the composition is no greater than 20000mm 2 / s; -50 ° C The viscosity of the composition is not more than 25,000 mm 2 /s at a temperature and a pressure of -0.05 MPa. Therefore, the combination of the hydrocarbon refrigerant and the refrigerating machine oil satisfying the above conditions can effectively improve the working energy efficiency of the rotary compressor, and more importantly, the above composition can effectively prevent the refrigeration oil from being occluded and expanded after being brought into the throttle mechanism. Valves or capillaries, which effectively improve the reliability of the air conditioning system. According to a specific embodiment of the present invention, since the above composition does not exceed 25,000 mm 2 /s even at a low temperature of -50 ° C, the throttle mechanism is not blocked, and the hydrocarbon refrigerant can maintain a normal flow rate. The rotary compressor can operate normally. Therefore, the use of a composition comprising a hydrocarbon refrigerant and a refrigerating machine oil having the above properties can significantly improve the stability of the air conditioning system.

Meanwhile, according to a specific embodiment of the present invention, the viscosity of the refrigerator oil in the rotary compressor at 40 degrees Celsius is 12 to 160 mm 2 /s. This makes it possible to meet the viscosity requirements of lubricating rotary compressors.
根据本发明的具体实施例， 上述旋转式压缩机内的冷冻机油的倾点为 -100〜- 31摄氏度。 由此该冷冻机油即使在较低的温度下其粘度也不会过低， 进而采用该冷冻机油可以进一步 提高旋转式压缩机的能效和空调系统的可靠性。  According to a specific embodiment of the present invention, the refrigerating machine oil in the rotary compressor has a pour point of -100 to -31 degrees Celsius. Therefore, the viscosity of the refrigerating machine oil is not too low even at a relatively low temperature, and further, the refrigerating machine oil can further improve the energy efficiency of the rotary compressor and the reliability of the air conditioning system.
