Embodiment Construction
[0050] The ADRC feed-forward control method of a lithium bromide absorption refrigerator proposed by the present invention will be described in detail below in conjunction with the accompanying drawings.
[0051] figure 1 A schematic diagram of a hot water type single-effect lithium bromide absorption refrigerator system is given. It should be noted that the ADRR feedforward method proposed by the present invention is not only applicable to figure 1 The shown hot water type single-effect lithium bromide absorption refrigerator can also be applied to double-effect type and flue gas steam type units. The reason is that the controlled object and control quantity of the above-mentioned other types of lithium bromide absorption refrigeration units are the same as the hot water type single-effect units, both are the outlet temperature of the refrigerant water and the flow rate of the heat source, and the disturbance sources affected by the system are also similar. For the direct c...
