When the ambient temperature drops below -5℃, the operating performance of ordinary scroll compressors will drop significantly, which is manifested in reduced heating efficiency and poor operating stability. The Copeland ZW Series Scroll Compressor For Heat Pump adopts an enhanced scroll plate structure and specially formulated low-temperature lubricating oil. Its precise mechanical design and material selection enable the compressor to maintain efficient and stable operation in an extremely low temperature environment of -20℃. This feature makes it particularly suitable for use in high-latitude areas such as northern China and Europe.
Test data shows that its heating capacity is 40% higher than the industry benchmark product, and this advantage is particularly obvious in cold environments. To achieve this breakthrough, engineers have deeply optimized the compression ratio and refrigerant circulation system. Some high-end models are also equipped with advanced jet enthalpy increase technology, which significantly improves the heating efficiency of the compressor in extremely cold weather by supplementing air in the middle, effectively avoiding the common performance drop of ordinary compressors under low temperature conditions.
To ensure long-term and reliable operation in low temperature environments, the ZW series adopts a number of innovative designs. Key components such as scroll plates and bearings are made of special alloy materials and surface treatment processes, which greatly improves the low-temperature tolerance of components. Secondly, the intelligent oil return control system ensures that the lubricating oil can still circulate smoothly in low-temperature environments by optimizing the oil return pipeline design and variable frequency speed regulation technology. In addition, the innovative anti-liquid impact design effectively reduces the risk of compressor failure at low-temperature startup through gas-liquid separation technology and preheating function.
Energy efficiency ratio is an important indicator to measure the performance of heat pump systems. The COP value of ordinary compressors usually drops by 30%-50% at an ambient temperature of -10℃. The ZW series uses high-efficiency motors and optimized refrigerant systems to maintain energy efficiency performance that is more than 20% higher than ordinary products under the same low-temperature conditions. This advantage enables heat pump systems using ZW series compressors to significantly reduce energy consumption costs when operating in winter.
In the civil field, it can provide a stable hot water supply for families in northern regions; in the commercial field, it can meet the large-scale hot water needs of hotels, schools and other places; in heating applications, when used with floor heating or fan coil systems, it can continuously output sufficient heat even in a severe cold environment of -20℃. This wide range of application adaptability makes it an ideal choice for heat pump systems in cold regions.
