The opening and closing angle of the valve plate 25 is controlled according to the humidity in the storehouse during baking or the oxygen concentration during refrigeration, and when the humidity oxygen concentration in the storehouse is greater than or less than the target humidity oxygen concentration, the operation of the stepping motor 24 is controlled to increase or reduce the opening degree of the valve plate according to a certain rule so as to control the flow rate of the air channel.
The specific control mode is that when the baking humidity is controlled, the humidity in the baking room is recorded as Ht, the target humidity in the baking room is recorded as Hset, and the humidity metering mode is relative humidity. The opening and closing angle range of the flow control valve is 0-K, K is 90 degrees, the opening angle of the flow control valve is controlled according to different humidity conditions in the curing barn and is recorded as At, the value of At is calculated according to the following formula, wherein S is a calculation coefficient, S is preferably 2, at-1 is the actual opening angle of the flow control valve At the last moment in the actual operation process, the opening angle of the flow control valve is detected and controlled once every time t, and the value of t is preferably 1min.
The calculation formula of the opening angle during humidity control is as follows:
when the refrigerated goods are stored for a long time, the oxygen in the refrigerating chamber is continuously consumed by the respiration of the refrigerated goods, when the oxygen concentration in the refrigerating chamber is too low, the quality of partial agricultural products can be influenced, and if the oxygen concentration is too low, potatoes can be blackened. When the oxygen concentration is controlled, the oxygen concentration in the curing barn is recorded as Qt, the target humidity in the curing barn is recorded as Qset, the opening and closing angle range of the flow control valve is 0-K, K is 90 degrees, the opening angle of the flow control valve controlled according to different humidity conditions in the curing barn is recorded as At, and the value of At is calculated according to the following formula, wherein S is a calculation coefficient, S is preferably 2, at-1 is the actual opening angle of the flow control valve At the last moment in the actual operation process, the opening angle of the flow control valve is detected and controlled once every time t, and the t value is preferably 1min.
The calculation formula of the opening angle during oxygen concentration control is as follows:
in order to ensure good heat insulation of the curing barn, the whole storehouse with the design is closed, so that the multifunctional heat pump is specially designed, when the tobacco curing needs to be dehumidified, the valve plate 25 is automatically opened, the high-humidity air in the tobacco containing chamber 6 is exhausted after passing through the cross-flow heat exchanger 21, and meanwhile, a part of energy is recovered; when the agricultural products are refrigerated, the quality of partial agricultural products is affected when the oxygen concentration in the storehouse is too low, a small amount of oxygen needs to be sucked at the moment, the valve plate 25 is automatically opened when the oxygen needs to be sucked, the air in the smoke room 7 is discharged after passing through the cross-flow heat exchanger 21, and partial cold energy is recovered; the whole flow direction of the air discharged from the tobacco house 7 to the outside of the baking house 7 is baking house 7 → valve opening 25 → cross flow heat exchanger 21 → heat exchanger 116, the air discharged from the baking house can recover most of the energy efficiency of the discharged air firstly through the cross flow heat exchanger (21) and then through the heat exchanger 16, and the air-source heat pump has a vital function of improving the energy efficiency ratio of the multifunctional air-source heat pump 9. Air in the refrigerating chamber is discharged out of the refrigerating chamber while a part of outdoor air is sucked from the outside of the refrigerator through the cross flow heat exchanger 21 to raise the oxygen concentration in the refrigerating chamber.
