Copeland Scroll Compressor ZW ZWD Series

Copeland Scroll ZW for heat pump water heating Compared to electric heaters or coal-fired boilers, Copeland ZW heat pump compressors provide higher energy efficiency ratios for residential hot water and comfort heating. From sanitary heating, residential space heating, agricultural drying and other industrial heating applications, Copeland, with experience of producing over 100 million scroll compressors is world renowned for efficiency and reliability.

Copeland ZW heat pump compressors employ EVI technology to create a strong “core” for any heating system. EVI technology effectively expands the operating ranges for heat pumps with an ambient temperature range of -30°C and increasing energy efficiency by 22%. Hot water temperatures of up to 85°C are achievable for residential heating and even meets the industrial application requirements.

Copeland ZW heat pump compressors are uniquely designed with higher compression ratios and larger pressure difference, allowing for systems to operate under wider conditions compared to ordinary heat pump or air-conditioning compressors. Equipped with highefficiency and high-power motors, ZW compressors meet the toughest challenges for heat pumps and water heaters even in the harshest ambient conditions. The flexibility of ZW compressors allows for installation in tandems to meet greater heating requirements.

Copeland ZW digital scroll compressors utilize axial compliance allows the fixed scroll to move vertically, by a very small amount, to ensure that the scrolls are always radially loaded with optimal force. This holds the two scrolls together, at all operating conditions, ensuring high efficiency. When the Copeland Digital Scroll is operating in normal “Loaded” mode the compressor behaves just like a standard scroll compressor providing 100% capacity. Within a certain period (such as 15 seconds) the output capacity is the sum of the average time of the loading and unloading state. By altering the loading and unloading time, it realizes the stepless adjustment of 10-100% of the compressor capacity to achieve precise temperature control.

In addition, ZW compressors can use environmentally friendlier zero ODP refrigerants and in combination with high efficiency technology solutions effectively reduce CO2 emissions to minimize environmental impact.
