Inverter Scroll Compressors for Heat Pumps
Inverter Scroll Compressors for Heat Pumps
 

MILAN (ITALY) / BIRMINGHAM (UK) March 27/13, 2012 - The heating market specified the requirements: solutions that continuously adapt the amount of heat generated to the actual heat load while maintaining very high efficiency levels. Emerson Climate Technologies therefore developed the first ZHW08 and ZHW16 Copeland Scroll™ Variable Speed compressors with inverter, specifically designed for heat pump applications. Manufacturers now have new possibilities of increasing efficiency, in particular for air / water heat pumps. For this application, operating conditions vary significantly, thus a specifically designed compressor is needed. The two models are equipped with a new brushless permanent-magnet motor to allow the compressor speed to continuously adapt between 30 and 117Hz. For the targeted heat pump application, the advantage is the ability to precisely provide the required heating power during the heating season. Furthermore, monovalent operation is also possible because both models feature the Copeland Enhanced Vapor Injection technology thanks to which condensing temperatures of 65°C can be achieved at evaporating temperatures as low as -25°C. The maximum condensing temperature is 68°C, presently the highest possible value in the market for compressors using R410A refrigerant. The inverter complies with all regulations regarding electromagnetic compatibility and other important guidelines for use in the building sector, such as VDE. The ZHW08 and ZHW16 models address a heating power range between 4 and 16 kW. They will be launched on the market in spring 2012. End users will get with these compressors, dedicated heat pumps with best performance in efficiency, CO2-emissions and costs. Additionally, new low energy housing and the refurbishment sector become independent from other energy sources.
