While the design of the mixed refrigerant system test apparatus is related to the two-stage cascade refrigeration system shown in Figure 1, it only uses one single-stage compressor
Because this program tested only a single-stage compressor
, the aerodynamic work input (and power) remained the same between the adiabatic and diabatic tests.
As a result, the supply pressure required by the probe is reduced dramatically and a single-stage compressor
, comparable to a small refrigeration compressor, can be used to energize the system.
has announced the availability of its most energy efficient single-stage compressor
, the 7500 S-energy[R] Series with Energy Efficiency System (EES) heat recovery.
With the light-weight aluminum construction, this model is roughly 7 kg lighter than conventional single-stage compressors
, which ensures further reductions in fuel consumption.
The product line includes two single-stage compressors
, which provide 16.
Hasegawa USA, San Antonio, Texas, USA (Fax: 1-210-494-9680), has broadened its Surely[R] range of reciprocating compressor applications by introducing the VZL4 and VZ6 single-stage compressors
as well as the new VZL31 and VZ42 two-stage compressors.
Owing to the much higher resistance to wear and the inherent durability of cast iron components, as compared to aluminium, the new Ecomaster single-stage compressors
are competitive in price with the aluminium reciprocating ones, and offer much higher reliability and longer life performance, we are assured.
