twostage rotary compressor. The result shows that the volume ratio of the optimal COP of the compressor corresponding to different operating conditions is not the same. In the freezing conditions, as shows in Figure 5, the proportion of COP increases first and decreases with the increasing of the volume ratio, it shows a parabolic trend.

compressor employs rotary and scroll mechanisms for the first and second stages respectively as the most suitable compression mechanisms for a heatpump water heater. This innovative combination of scroll and rotary mechanisms enables high reliability and high efficiency under a wide range of operating conditions.

discharge and the coolers are critical for fine material, high primary air and a precombustion chamber was considered, and second air management applied. Also, a water spray system was considered for the short rotary cooler. Due to the high lengthtodiameter ratio and the low feedstock moisture, no lifters were considered.

The RAC operating temperature, approximately 840F on the air side and more than 450F on the water side, is above the 140F minimum critical temperature, and thus is well within range for SCC to occur. A DOE report, DOE Fundamentals Handbook Chemistry Volumes 1 and 2 , adds that as temperatures increase, the time to metal failure from SCC decreases.

Rotary coolers work by tumbling material in a rotating drum in the presence of chilled or ambient air. The drum is set at a slight horizontal slope to allow gravity to assist in moving material through the drum. Lifting flights maximize heat transfer efficiency by lifting up material and dropping it through the chilled air as the drum rotates.

As compression ratio increases, so does compressor discharge temperature. Excessive heat is of primary concern as it is the forerunner of high maintenance costs due to lubrication breakdown, and valve carbonization. Suction superheat must be controlled very closely especially on ammonia systems operating at high compression ratios.
