High-low Speed Control Algorithm for Direct Expansion Air-Conditioning Systems for Improved Indoor Humidity Control and Energy Efficiency
- Summary
- The invention relates to a method for cooling and drying enclosed environment by a direct-expansion air conditioner, comprising the following steps: 1. setting one preset value aiming at the enclosed environment and storing the values in memory of a control mechanism; 2. acquiring measurement values by one measuring instrument in the encloses environment and storing the values in the memory of the control mechanism; 3. judging whether the measurement values are higher than the preset values; if yes, carrying out step 4, and if not, carrying out step 5; 4.leading high-speed operation of a compressor to reach steady state or maintaining the steady state of the high-speed operation of the compressor and simultaneously returning to the step 2; and 5. leading low-speed operation of the compressor to reach steady state or maintaining the steady state of the low-speed operation of the compressor and simultaneously returning to the step 2.
