  • High-low speed control algorithm for direct expansion air-conditioning systems for improved indoor humidity control and energy efficiency
    Publication number: 20080135635
    Abstract: The present invention relates a method of dehumidifying an enclosed environment with a direct expansion air conditioning system, such direct expansion air conditioning system containing a two speed compressor and a two speed supply fan that allows the compressor and supply fan to run at high speeds in a steady-state or low speeds in a steady-state for better humidity control. Such a system allows for a more efficient, less costly system in comparison to single speed direct expansion air conditioner or direct expansion air conditioners with variable speed compressors and supply fans.
