HOW IT WORKS

A "rotatable lobe" (see graphics below) replaces one standard eccentric on a two-piston crankshaft. It automatically positions itself to allow two pistons to operate in forward rotation. In reverse, the lobe repositions itself at the center axis of the shaft, allowing one of the pistons to idle.

The compressor motor is easily reversed and allowed to operate at peak efficiency by using the start winding of the two-piston operation as the run winding, and the run winding as the start winding, the company explains. One additional relay in the run-winding circuit makes this happen.

In reversing motor direction, Bristol employs either a two-minute-delay in the relay to allow system equalization, or a hard-start kit to allow the motor to reverse against load. Capacity choice is controlled by a standard mechanical or electronic two-stage thermostat.

"You have virtually two compressors, but only one footprint; and more importantly, the cost of one compressor," Young notes. "The oem can offer multiple efficiencies in existing models without changing designs." The same approach is applied to a four-piston compressor, with rotatable lobes idling two of the four pistons, he explains. "Oem's are now offered design options they've not been able to consider before the "TS" technology came to light." Capacity can split 50%/100%, 40%/100%, 60%/100%, or whatever the manufacturer wants, Young says. This also allows "regionalizing" products - heat pumps, specifically.

"Until now, you've often had to compromise heat pump performance to avoid having too much cooling capacity and added cost."

Young also notes improved humidity control and sound level with TS' modulating performance.
