AUTOMATED DRIVE FOR FAN AND REFRIGERANT SYSTEM |
摘要 |
A refrigerant system is provided with a variable speed drive for at least one of its fluid-moving devices, wherein the variable speed drive is provided by an automated mechanical drive. In the disclosed embodiment, one of the pulleys for driving the fluid-moving device has a variable diameter to vary the speed at which the fluid-moving device is driven. The pulley may include two plates that are biased in one direction by a spring or permanent magnet force, and in an opposed direction by a hydraulic or electro-magnetic force. A control adjusts the amount of hydraulic or electro-magnetic force delivered to the plates to achieve a desired speed for the fluid-moving device. |
