Referring to fig. 1, the refrigerating system of the incubator includes a compressor 1, a condenser 2, an evaporator 3, and a connecting line; a flow control valve 4 is arranged on a connecting pipeline between the evaporator 3 and the condenser 2, one end of the flow control valve 4 is communicated with an outlet of the condenser 2, the other end of the flow control valve 4 is communicated with an inlet of the evaporator 3, and the flow control valve is used for adjusting the flow of a refrigerant flowing into the evaporator 3 in real time, wherein the compressor 1 is a variable frequency compressor or a fixed frequency compressor.
In the embodiment of the disclosure, the flow control valve is arranged at the inlet of the evaporator, and can form closed-loop control according to the real-time temperature in the incubator to control the flow of the refrigerant flowing into the evaporator, so that the effective heat exchange area of the evaporator is changed, and different temperature requirements of the incubator are met.
In some embodiments, the refrigeration system further comprises a bypass capillary tube 5, one end of the bypass capillary tube 5 is communicated with the outlet of the condenser 2, and the other end is communicated with the inlet of the compressor 1; a bypass capillary tube 5 is connected in parallel with the flow control valve 4 and the evaporator 3. In the embodiment of the disclosure, when the flow control valve 4 is completely closed, in order to ensure the normal operation of the refrigeration system, the bypass capillary 5 is provided to satisfy the normal circulation of the refrigeration system. As a preferable scheme, the bypass capillary tube 5 is connected to the air return pipe of the compressor 1, so that the bypass capillary tube not only can realize the normal operation of the refrigeration system when the flow control valve is closed, but also can reduce the air return temperature when the flow control valve is opened, thereby avoiding the over-high exhaust temperature.
With reference to fig. 2, an embodiment of the present disclosure provides a method for adjusting the temperature of an incubator, including:
and S01, detecting the temperature in the incubator by using a temperature sensor.
S02, determining the opening degree of the flow control valve by the processor according to the difference between the temperature in the incubator and the target temperature; the opening degree of the flow control valve is within a preset opening degree range, and the temperature of the incubator is reduced along with the increase of the opening degree of the flow control valve within the preset opening degree range.
And S03, controlling the opening of the flow control valve by the processor.
In the embodiment, a temperature sensor is arranged in the incubator and used for detecting the temperature in the incubator in real time, a processor of the incubator determines the opening of the control valve according to the temperature condition in the incubator, and the control valve is controlled to be opened to the corresponding opening; specifically, the opening degree of the flow control valve may be adjusted according to the difference between the temperature in the incubator and the target temperature; for example, when the temperature in the incubator is higher than the target temperature, the opening degree of the flow control valve is adjusted, the flow rate of the refrigerant flowing into the evaporator is increased, and the heat absorption capacity of the evaporator is increased, so as to reduce the temperature in the incubator; when the temperature in the incubator is lower than the target temperature, the opening degree of the flow control valve is reduced, the flow of the refrigerant flowing into the evaporator is reduced, and the heat absorption capacity of the evaporator is reduced, so that the temperature in the incubator is increased. Alternatively, a closed-loop feedback may be formed according to a difference between the temperature in the incubator and the target temperature, and the opening of the flow control valve may be adjusted in real time to control the stability of the temperature of the incubator by implementing a PID (proportional-Integral-Differential) control algorithm or other algorithms to implement feedback control.
In this embodiment, the opening degree of the flow control valve is within a preset opening degree range, and in the preset opening degree range, the flow control valve can realize the circulation of the minimum refrigerant flow, so as to realize the control of the temperature in the incubator, wherein the target temperature is close to the ambient temperature; the requirement of the lowest target temperature in the incubator can be met, so that the control of the requirement of the lowest temperature in the incubator is realized; when the target temperature is between the lowest temperature and the environment temperature, the refrigerant flow of the evaporator is increased along with the increase of the opening degree of the flow control valve, and then the effective heat exchange area of the evaporator is gradually increased until the effective heat exchange area reaches the maximum value, so that the temperature in the incubator is reduced along with the increase of the opening degree of the flow control valve.
In some embodiments, an air cooling circulation, namely a fan, is arranged in the incubator and is used for realizing the air circulation flow in the incubator and transmitting the cold energy generated by the evaporator into the incubator so as to ensure that the temperature in the incubator is uniformly distributed; in this case, the installation position of the temperature sensor should be properly selected, and the detected temperature should reflect the average temperature in the incubator, so as to improve the detection accuracy.
By adopting the method for adjusting the temperature of the incubator provided by the embodiment of the disclosure, the opening of the flow control valve is controlled within a preset opening range through the difference value between the temperature in the incubator and the target temperature, and the flow of the refrigerant of the refrigerating system is adjusted, so that the effective heat exchange area of the evaporator is changed, different heat exchange amounts are realized, and further the adjustment of the temperature in the incubator body is realized; compared with the prior art, the scheme does not need to control the compressor to be frequently started and stopped, does not need a heating pipe to carry out thermal compensation, and is beneficial to reducing energy consumption.
Optionally, the preset opening range is [0, k ]; wherein the opening k is smaller than the maximum opening of the flow control valve.
In the embodiment of the disclosure, the preset opening range of the flow control valve is [0, k ], and the opening k is smaller than the maximum opening of the flow control valve; generally speaking, when the circulating air quantity in the box is constant, the realization of the temperature in the box depends on the heat exchange temperature difference and the effective heat exchange area. Specifically, as shown in fig. 4, the dotted line in the figure indicates the relationship between the inside temperature and the opening degree of the flow control valve, the thick line indicates the relationship between the effective heat exchange area of the evaporator and the opening degree of the flow control valve, and the thin line indicates the relationship between the heat exchange temperature difference of the evaporator and the opening degree of the flow control valve; the opening of the flow control valve is continuously increased, so that the flow of the refrigerant flowing into the evaporator is gradually increased, the evaporation range of the refrigerant in the evaporator is enlarged, the low-temperature range of the surface of the evaporator extends from the inlet to the outlet, and the low-temperature area is continuously increased, so that the heat exchange area with the circulating air in the box is gradually increased until the whole area of the evaporator is the effective evaporation area; at the moment, the heat exchange area of the air in the box reaches the maximum and is not increased any more; simultaneously, at the in-process of flow control valve opening crescent, the internal pressure of evaporimeter can rise along with the flow increase, makes evaporating temperature rise, shows as evaporimeter surface temperature rise, and the heat transfer difference in temperature of the in-box flowing air and evaporimeter reduces gradually. Therefore, under the combined action of the heat exchange area and the heat exchange temperature difference, in the process that the opening degree is from small to large, the heat exchange area plays a main influence role firstly, then the influence role is gradually reduced, and the heat exchange temperature difference is gradually changed into the heat exchange temperature difference, namely the internal pressure of the evaporator plays a main influence role, and in the whole change process, the temperature in the incubator tends to increase after being reduced firstly, so that in general conditions, when the opening degree of the flow control valve is maximum, the incubator cannot obtain the lowest refrigeration temperature, and the phenomenon that the temperature in the incubator rises on the contrary when the opening degree is larger and the surface temperature of the evaporator is higher can exist; the lowest refrigerating temperature in the refrigerator cannot be realized, and the temperature control performance of a refrigerating system and a control system is influenced. For this phenomenon, in this embodiment, a preset opening range of the flow control valve is set, and the flow control valve can realize adjustment from 0 to k, and in the preset opening range, the temperature of the incubator decreases with the increase of the opening of the flow control valve, that is, the temperature of the incubator mainly depends on the effective heat exchange area of the evaporator; thus, the temperature in the incubator and the opening degree of the flow control valve are linearly related, a wide temperature setting range can be realized, and additional heating compensation is not required.
Alternatively, the opening k is determined according to the effective heat exchange area of the evaporator, or according to the temperature in the incubator.
In this embodiment, the preset maximum opening k of the flow control valve may be determined according to the effective heat exchange area of the evaporator, or the target temperature in the incubator. Specifically, as can be seen from the relationship between the effective area of the evaporator, the heat exchange temperature difference, and the opening of the flow control valve, when the opening is within a certain range, the temperature in the tank body decreases as the opening of the flow control valve increases; at the moment, the temperature change in the box body mainly depends on the effective heat exchange area of the evaporator; therefore, the opening k can be determined according to the effective heat exchange area of the evaporator, or the target temperature in the tank.
Optionally, the opening k is an opening of a flow control valve corresponding to the maximum effective heat exchange area of the evaporator; alternatively, the opening k is an opening of the flow rate control valve corresponding to a case where the temperature in the incubator reaches the minimum target temperature.
In the embodiment of the disclosure, when the effective heat exchange area of the evaporator reaches the maximum effective heat exchange area along with the increase of the opening degree of the flow control valve, the opening degree of the corresponding flow control valve is a preset maximum opening degree k; in the range from 0 to the preset maximum opening, the cold quantity of the evaporator can be increased along with the increase of the opening of the flow control valve, so that a wider temperature range is realized; or when the temperature in the incubator reaches the lowest target temperature along with the increase of the opening of the flow control valve, the corresponding opening of the flow control valve is a preset maximum opening k, and the temperature in the incubator and the opening of the flow control valve are in a linear relation within the range from 0 to the preset maximum opening; the wide temperature range from the lower temperature in the box to the ambient temperature can be adjusted. Furthermore, it should be noted that the maximum effective heat exchange area of the evaporator depends on the actual maximum heat exchange area of the evaporator, which is determined by the maximum heat load of the refrigeration system.
Alternatively, as shown in fig. 3, in step S02, the processor determines the opening degree of the flow control valve according to the difference between the real-time temperature and the preset temperature, including:
s21, calculating the output power of a PID control algorithm by the processor according to the difference value between the temperature in the incubator and the target temperature;
and S22, the processor determines the opening of the flow control valve according to the corresponding relation between the output power and the opening of the flow control valve.
In the embodiment of the disclosure, the opening degree of the flow control valve is adjusted through a PID control algorithm. Specifically, the difference value between the temperature in the incubator and the target temperature is used as an input variable of a PID control algorithm, and the output power of the refrigeration system corresponding to the temperature difference value is obtained; the output power of the refrigerating system and the opening degree of the flow control valve have a corresponding relation, and the opening degree of the corresponding flow control valve can be determined through the corresponding relation; thereby controlling the flow control valve to a corresponding opening degree, and enabling the refrigerating capacity flowing into the evaporator to meet the requirement of the target temperature refrigerating capacity. Therefore, the opening of the flow control valve is accurately controlled through a PID control algorithm, the control requirement that the fluctuation range of the temperature in the box is +/-0.1 ℃ can be met, and the fluctuation caused by frequent startup and shutdown of the compressor is avoided.
Alternatively, the larger the output power, the larger the opening degree of the flow control valve.
In the embodiment of the disclosure, the corresponding relationship between the output power and the opening degree of the flow control is a one-to-one corresponding relationship, that is, the larger the output power is, the larger the opening degree of the control flow valve is, so that the output power through the PID control algorithm directly corresponds to the opening degree of the control flow valve, and the real-time adjustment of the temperature in the incubator is realized.
Alternatively, step S03, the processor controls the flow rate control valve to open to an opening degree, including: when the opening is zero, the bypass capillary tube is controlled to flow at a refrigerant flow rate that satisfies the minimum rotation speed of the compressor.
In the embodiment of the disclosure, when the opening degree of the flow control valve is zero, that is, when the flow control valve is closed, in order to ensure that the refrigerant flow rate of the main flow path where the flow control valve is located is zero, the bypass capillary tube is controlled to flow at the refrigerant flow rate satisfying the lowest rotation speed of the compressor in order to normally operate the refrigeration system. In this way, refrigerant circulation of the refrigeration system is accomplished by means of the bypass capillary tube.
Optionally, S21, after the processor calculates the output power of the PID control algorithm according to the difference between the temperature in the incubator and the target temperature, the method further includes: and controlling the variable frequency compressor to operate according to the output power.
In the embodiment of the disclosure, after the output power of the PID control algorithm is obtained, the inverter compressor is controlled to operate according to the output power, that is, the output power of the inverter compressor is increased or decreased according to the temperature in the incubator and the target temperature, so that the frequency of the inverter compressor is matched with the flow rate of the refrigerator, the high-frequency operation of the compressor is avoided, the load of the compressor is reduced, the refrigeration system is operated reasonably, and energy saving is achieved.
The embodiment of the disclosure provides a device for adjusting the temperature of an incubator, which comprises a detection module, a determination module and a control module. The detection module is configured to detect a temperature within the incubator; the determination module is configured to determine an opening degree of the flow control valve according to a difference between the temperature inside the incubator and the target temperature; the opening degree of the flow control valve is in a preset opening degree range; the control module is configured to control the flow control valve to open to an opening degree.
