簡介 Introduction：
氫氟碳化合物是無氯氣體，目前已取代全球範圍內的氯氟烴（CFC）氣體，成為更環保的製冷劑。
HFC-134a是一種無臭氧消耗潛能（ODP）的HFC，是主要使用的製冷劑。
HFC與礦物油基潤滑劑系統之間的相容性差，導致引入了用於製冷劑應用的合成潤滑劑。
合成PAG潤滑劑在汽車工業中作為適用於空調系統的合成油已被廣泛確立，

Lubeta CXL PAG的新穎結構差異也確保了潤滑劑能夠滿足各種工業裝配的性能要求，
以及家用製冷劑和空調系統。
Lubeta CXL與各種HFC的混溶性確保了它們適用於各種製冷劑，包括1,1,1,2-四氟乙烷（R134a），
二氟甲烷（R32），五氟乙烷（R125），1,1， 1-三氟乙烷（R143a）
和基於這些混合物的混合製冷劑（R-404A，R-407C，R-410A，R-507）。

通常，諸如在汽車空調設備中發現的壓縮型製冷設備由壓縮機，冷凝器，膨脹球和蒸發器組成。
在這種製冷裝置中，通常溫度可以升高到40℃，通常是65℃或更高，而在冷卻器中，溫度可能低至-40℃。
用於汽車空調設備中的PAG冷凍油是眾所周知的，但是它們可能會遇到兩個關鍵問題。
首先，在接近室溫和高於室溫的溫度下與HFC進行相分離。
產生的富含HFC的相會導致潤滑不良並縮短壓縮機壽命，並且在關鍵溫度區域分離潤滑劑會降低壓縮機效率。
為了有效地潤滑壓縮機，避免相分離至關重要。
其次，PAG冷凍油具有吸濕性，超過可接受水平的水吸收會導致膨脹球中的水凍結，從而降低效率和潤滑。

Lubeta CXL潤滑劑基於一種新的“封蓋”技術，可為壓縮式製冷機組提供有效的潤滑，
在整個溫度範圍內具有良好的製冷劑溶解性，並大大降低了吸水的趨勢，
封蓋後可改善潤滑性能技術提高了在所有應用程序中使用的適用性。

HFCs are chlorine-free gases, now replacing chlorofluorocarbon (CFC) gases worldwide as more environmentally acceptable refrigerants. HFC-134a, a HFCs which has no ozone depletion potential (ODP), is the principle refrigerant in use. Poor compatibility of HFCs with mineral oil based lubricant systems has led to the introduction of synthetic lubricants for refrigerant applications.

Synthetic PAG lubricants are well established in the automotive industry as a synthetic fluid suitable for use in air conditioning systems, with the novel structural difference of Lubeta CXL PAGs also ensuring the lubricants meet the performance requirements for use in the assembly of a wide range of industrial and domestic refrigerant and air conditioning systems. Miscibility of the Lubeta CXLs with a wide range of HFCs ensures their suitability for use with a range of refrigerants, including 1,1,1,2- tetrafluoroethane (R134a), difluoromethane (R32), pentafluoroethane (R125), 1,1,1-trifluoroethane (R143a) and blending refrigerants (R-404A, R-407C, R-410A, R-507) based on blends of these.
Generally, a compression type refrigeration unit, such as found in automotive air-conditioning units, consists of a compressor, a condenser, expansion bulbs and an evaporator. In such a refrigeration unit, usually the temperature can rise to 40℃, often 65℃ or more, while in the cooler the temperature may be as low as -40℃. PAGs for automotive A/C units are well known, however they can suffer from two key problems. Firstly, one of phase separation with the HFC at temperatures close to room temperature and above. The resulting HFC-rich phase can result in poor lubrication and reduced compressor life, with separation of lubricant in critical temperature regions in reduced compressor efficiency. For efficient lubrication of the compressor avoidance of phase separation is therefore crucial. Secondly, PAGs are hygroscopic and the absorption of water above acceptable levels can cause freezing out of water in the expansion bulbs, resulting in reduced efficiency and lubrication.

Lubeta CXL lubricants, based on a new “capping” technology, provide efficient lubrication for compression type refrigeration units, with good refrigerant solubility over the full temperature range, and a substantially reduced tendency to absorb water, Improved lubricating properties as a result of the capping technology improves suitability for use in all applications.
