Additionally, the lineup offers a capacity range of 260 RT to 1100 RT for single compressor and from 520 RT to 2200 RT for dual compressor
based on conditions of the Air Conditioning and Refrigeration Institute (AHRI) standard.
This application further demonstrates that a dual compressor
system with isolated suction lines can improve the stability of a dynamic refrigeration system, while at the same time allowing for a reduction in compressor displacement.
Avance Nerve Graft is processed and sterilised in America and then transported to the Hospital Innovations site in St Mellons, where they are stored in the company's Daihan Dual Compressor
"The chillers are dual compressor
centrifugal chillers with a closed loop condenser cooling water circuit.
The ServiceMate will become a standard feature on all brands of product, including Single and Dual Compressor
Vertical Condensing Units, 3-40 HP Semi-Hermetic Horizontal Condensing Units.
of North America, Wood Dale, Ill., cascade freezers require larger single or dual compressors
operating together to provide temperatures below -50 C, which translates into a higher energy requirement while still maintaining rapid temperature recovery times.
The 1-ton EP1 chillers have rotary compressors and all larger models have scroll compressors (dual compressors
for larger than 20 tons, allowing compressors to be staged for low loads).
A system diagram for a single-stage ammonia refrigeration system with high and low temperature evaporators with dual compressors
is shown in Figure 1a, and a pressure-enthalpy (P-h) diagram for the system is shown in Figure 1b.
(On the other hand, dual compressors
provide redundancy and better efficiency at low loads.) Also new are electronic expansion valves, said to raise energy efficiency at reduced head pressures.
