Danfoss variable speed scroll adds injection

DENMARK: The Danfoss VZH-VI variable speed scroll compressor with injection enables the design of units that achieve high performance in comfort control, cooling and low ambient heating.

Used alongside the Danfoss fixed speed compressor range and combined with the full Danfoss qualified injection package, the VZH range provides full system solution for heat pumps.

Adding injection to the VZH ensures that even in heating mode, space conditions can be modulated to precise settings. It also increases the system capacity and efficiency in both heating and cooling operation while maintaining the same compressor footprint. 

The compressor range provides system capacity and energy efficiency benefits both in cooling and heating operating modes, with the ability to operate across a wide frequency range. 

Vapour injection can increase refrigeration capacity and system efficiency in a wide range of applications, while also allowing units to operate in colder ambient conditions by expanding the compressor operating envelopes.
