Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a humidity control method of a maturation cabinet, which comprises the following steps of:
s1: acquiring a compressor starting signal and an average value CRH of integrated humidity values RH of N previous work periods of the compressor, wherein N is an integer greater than zero;
s2: controlling the compressor to start, if | CRH-75% | is less than or equal to 5%, the compressor keeps the frequency of the last working period; if | CRH-75% | > 5%, reduce or increase the frequency to a work cycle on the compressor;
s3: and acquiring a compressor stop signal, and controlling to close the compressor.
The compressor starting signal and the compressor stopping signal are specifically as follows: the preset temperature of the ripening chamber is T, and when the temperature of the ripening chamber is T + n ℃, a compressor starting signal is obtained; when the temperature of the ripening chamber is T-n ℃, the temperature is a compressor stop signal, wherein n is more than or equal to 0 and less than or equal to 3.
In the embodiment of the invention, the average value CRH of the integrated humidity RH of the previous N working periods of the compressor is calculated, and the absolute value of the difference value between the average value CRH and 75% of the set ripening humidity of the ripening cabinet is compared with 5%.
If the absolute value of the difference between the average CRH of the integrated humidity values RH of the previous N work periods of the compressor and the 75% of the set ripening humidity of the ripening cabinet is not more than 5%, it can be known that the average CRH of the integrated humidity values RH of the previous N work periods of the compressor is within the range of about 5% of the 75% of the ripening humidity, the ripening condition in the ripening cabinet is met, and the compressor keeps the frequency operation of the previous work period.
When the absolute value of the difference between the average value CRH of the integrated humidity values RH of the previous N working cycles of the compressor and 75% of the ripening humidity set in the ripening cabinet is greater than 5%, the frequency of the compressor needs to be adjusted so that the humidity in the ripening chamber is within the range of about 5% of the ripening humidity 75%.
In addition, when humidity is controlled, the humidity control method provided by the embodiment of the invention is provided with the starting temperature T + n ℃ of the compressor and the stopping temperature T-n ℃ of the compressor according to the preset temperature T of the ripening chamber, and when the temperature of the ripening chamber reaches T + n ℃, the temperature is the starting signal of the compressor, and the compressor is controlled to start; when the temperature of the ripening chamber reaches T-n ℃, the signal is the stop signal of the compressor, and the compressor is controlled to be closed.
The starting temperature and the stopping temperature of the compressor are set within the range of n ℃ up and down of the preset temperature T, n is more than or equal to 0 and less than or equal to 3, the large temperature fluctuation range in the ripening cabinet in the moisture control process can be avoided, and the stability of the temperature in the ripening cabinet is ensured while the moisture control is carried out.
The humidity control method for the ripening cabinet provided by the embodiment of the invention can control the humidity in the ripening chamber within the range that the 75% fluctuation of the ripening humidity is not more than 5%, and can control the temperature in the ripening chamber within the range that the preset temperature fluctuation is not more than n ℃ in the humidity control process, thereby solving the problems of small humidity control precision and large temperature fluctuation in the ripening chamber in the humidity control process of the existing ripening cabinet.
Specifically, in this embodiment, the maturation cabinet further includes an evaporator, an evaporation fan disposed in the air duct, and a humidity sensor disposed in the maturation chamber.
In the humidity control process, the evaporation fan keeps an open state. As the curing process has certain requirement on the wind speed, the evaporation fan needs to be kept in an open state, and the continuous operation of the evaporation fan enables the cold air in the curing chamber and the air duct to continuously keep a certain wind speed for circulation, thereby being beneficial to the curing of the meat products in the curing cabinet.
Furthermore, the temperature of the evaporator is-13 to-3 ℃, and the evaporation area of the evaporator is more than or equal to 1.3m 2 /100L。
The working cycle of the compressor in step S1 specifically refers to: the compressor is started after acquiring a compressor starting signal, the compressor is closed after acquiring a compressor stopping signal, the compressor is started after acquiring the compressor starting signal again, and the compressor is started to be started next time, namely a compressor working period.
In a working period of the compressor, the compressor comprises a starting state and a stopping state, when the compressor is in the starting state, the evaporator absorbs water vapor in the ripening chamber and condenses the water vapor into frost, and the humidity in the ripening chamber is reduced; when the compressor is in a shutdown state, the continuous operation of the evaporation fan is utilized to blow the frost vapor on the evaporator to the ripening chamber, and the humidity in the ripening chamber is increased.
The temperature of the evaporator is set to be the temperature which can ensure that the interior of the ripening chamber is refrigerated, and can prevent frost on the evaporator from being condensed into ice, so that the evaporation fan is difficult to convert the ice on the evaporator into water vapor to provide humidity for the ripening chamber; the evaporation area of the evaporator is large, the frosting area on the evaporator can be increased, and the operation of an evaporation fan is facilitated, so that the humidity of the ripening chamber is increased.
In step S1, the integrated humidity value RH of the working cycle of the compressor is specifically: the compressor starts to time, and in the working period, the humidity sensor obtains a relative humidity value rh every 10s i The first relative humidity value, the second relative humidity value, \8230;, and the last relative humidity value are successively recorded as rh 1 、rh 2 、……、rh n Integrated humidity value RH = (RH) 1 +rh 2 +…+rh n )/n。
Obtaining an integral humidity value RH in each working period of the compressor, and recording the integral humidity value RH in the first working period 1 And the integrated humidity value of the second duty cycle is recorded as RH 2 8230the integrated humidity value of the Nth working period is recorded as RH N Average CRH = (RH) of integrated humidity values RH of the first N operating cycles of the compressor 1 +RH 2 +…+RH N )/N。
The relative humidity of the ripening chamber is obtained at preset time intervals, the integrated humidity value RH of the relative humidity value obtained in one period is calculated, the integrated humidity value RH can better reflect the humidity of the ripening chamber in the period, the average value CRH of the integrated humidity values RH of N periods can better reflect the humidity of the ripening chamber in the period, and the comparison between the average value CRH of the integrated humidity values RH and the ripening humidity of 75% is more reasonable.
Preferably, N =3, the average value CRH of the integrated humidity values RH of the first three working cycles of the compressor is taken, so that not only can the humidity condition of the maturation chamber within a certain time be obtained, but also the time for obtaining the average value CRH of the integrated humidity values RH is prevented from being too long, the influence of the early-stage humidity on the average value CRH of the integrated humidity values RH is prevented, the comparison data between the average value CRH of the integrated humidity values RH and the maturation humidity 75% is inaccurate, and the compressor is not adjusted reasonably.
In step S2, when the absolute value of the difference between the average value CRH of the integrated humidity values RH of the previous three work cycles of the compressor and the ripening humidity 75% is not greater than 5%, that is, the average value CRH of the integrated humidity values RH of the previous three work cycles of the compressor is within a range of about 5% of the ripening humidity 75%, so as to satisfy the ripening condition in the ripening cabinet, and under this condition, the frequency of the compressor in the previous work cycle of the compressor is maintained, so as to continuously maintain the average value CRH of the integrated humidity values RH of the previous three work cycles of the compressor to satisfy the ripening condition of the ripening cabinet.
When the absolute value of the difference between the average value CRH of the integrated humidity values RH of the first three work cycles of the compressor and the ripening humidity 75% is greater than 5%, that is, the average value CRH of the integrated humidity values RH of the first three work cycles of the compressor is not within the range of about 5% of the ripening humidity 75%, and does not satisfy the ripening condition in the ripening cabinet, under which the frequency of the compressor needs to be adjusted.
Specifically, if the difference between the average CRH of the integrated humidity values RH of the first three working cycles of the compressor and the ripening humidity of 75% is greater than 5%, the humidity in the ripening chamber is higher, and the frequency of the compressor is reduced. After the frequency of the compressor is reduced, the refrigeration efficiency is reduced, the refrigeration time is prolonged, and the humidity in the ripening chamber is continuously reduced in the refrigeration process until a compressor stop signal is obtained to control the compressor to be closed.
And acquiring a compressor starting signal again, controlling the compressor to be started, and if the difference value between the average value CRH of the integrated humidity values RH of the previous three working periods of the compressor and the 75% of the mature humidity is still greater than 5%, continuously reducing the frequency of the compressor until acquiring a compressor stopping signal, and controlling the compressor to be stopped.
Preferably, the compressor frequency reduction is 20Hz. And after the frequency of the compressor is repeatedly circulated until the frequency of the compressor is reduced to the lowest frequency of the compressor, acquiring a starting signal of the compressor again, controlling the compressor to be started, and if the difference value between the average value CRH of the integrated humidity values RH of the previous three working periods of the compressor and the 75% of the ripening humidity is still more than 5%, starting a low-temperature compensation system, wherein the low-temperature compensation system comprises a heating wire arranged in an air duct of the ripening cabinet, and the electrifying rate of the heating wire is set to be 20%.
And acquiring a compressor starting signal again, controlling the compressor to be started, if the difference value between the average value CRH of the integrated humidity values RH of the previous three working periods of the compressor and the ripening humidity 75% is still more than 5%, increasing the electrifying rate of the heating wire by 20% until a compressor stopping signal is acquired, and controlling the compressor to be stopped. Repeatedly circulating until the energizing rate of the heating wire reaches 100 percent.
After the heating wire is opened, a small amount of heat generated by the heating wire is transferred to the ripening chamber through the evaporation fan, so that the working time of the compressor is increased, the refrigerating time is prolonged, and the time for reducing the humidity is further increased. If the circulation is carried out again, the difference value between the average value CRH of the integrated humidity values RH of the previous three working periods of the compressor and the ripening humidity is still more than 5%, namely the humidity in the ripening chamber is still higher, the electrifying rate of the heating wire is increased, more heat is provided for the ripening chamber, the refrigerating time is increased, and the humidity reducing time is increased.
If the difference value CRH between the 75% of the ripening humidity and the average value CRH of the integrated humidity RH of the previous three working periods of the compressor is more than 5% and more than 5%, namely the humidity in the ripening chamber is lower, the frequency of the compressor is increased, the refrigerating efficiency is improved after the frequency of the compressor is increased, the refrigerating time is shortened, and the shutdown time of the compressor in the period is prolonged.
In the stopping process of the compressor, the evaporation fan continuously rotates, on one hand, frost-formed water vapor condensed on the evaporator in refrigeration is blown to the ripening chamber to increase the humidity of the ripening chamber; on the other hand, air outside the ripening cabinet is sucked into the air duct and blown to the ripening chamber, and the outside air is utilized to humidify the ripening chamber.
And acquiring a compressor starting signal again, controlling the compressor to be started, and if the difference value between the mature humidity of 75% and the average value CRH of the integrated humidity values RH of the previous three working periods of the compressor is still greater than 5%, continuing increasing the frequency of the compressor until a compressor stop signal is acquired, and controlling the compressor to be stopped. The circulation is repeated until the absolute value of the difference between the average value CRH of the integrated humidity values RH of the previous three working periods of the compressor and the ripening humidity 75% is not more than 5%.
Preferably, the compressor frequency is increased by 10Hz.
It should be understood that although the present description refers to embodiments, not every embodiment contains only a single technical solution, and such description is for clarity only, and those skilled in the art should make the description as a whole, and the technical solutions in the embodiments can also be combined appropriately to form other embodiments understood by those skilled in the art.
