[0003] Most of the refrigeration systems in drug stability test chambers or constant temperature and humidity incubators used in conjunction with humidification systems in biopharmaceutical equipment are simple circulating water cooling or circulating air cooling methods. During operation, only a single heat exchange can be performed. , cannot be changed and cooled according to the needs of biopharmaceutical equipment, so it is not conducive to the use of drug stability test chambers or constant temperature and humidity incubators in biopharmaceutical equipment

experiment example
[0031] Such as figure 2 As shown, the cooling capacity split system is controlled by the controller 4 to start the operation of the compressor 1, and the cooling capacity in the cooling system is divided by the first electromagnetic valve 5 and the second electromagnetic valve 6, so that each temperature and humidity setting value is stable in the interval balance;
[0032] Control the operation or stop status of the first solenoid valve 5 and the second solenoid valve 6 according to the temperature and humidity range values, the first solenoid valve 5 and the second solenoid valve 6 are normally open; the S in the controller 4 represents the first solenoid valve 5, C represents the second solenoid valve 6, 0 means power off, 1 means power on; the upper interval point of the valve position: the measured temperature exceeds the temperature set value + the set value of the upper interval point, S and C are automatically powered on and closed, cooling The volume increases; the ...

The invention discloses a refrigerating capacity shunt system for pharmaceutical production equipment. The refrigerating capacity shunt system comprises a compressor, a condenser connected with the output end of the compressor, an evaporator connected with the compressor and the condenser and used for cooling the pharmaceutical production equipment in the humidifying treatment, and a controller electrically connected with the compressor; and the refrigerating capacity shunt system further comprises a first solenoid valve and a second solenoid valve which are arranged in parallel at the input end of the compressor, and the first solenoid valve and the second solenoid valve are further electrically connected with the controller. The refrigerating capacity shunt system can be applied to the pharmaceutical production equipment, and can be used in cooperation with a humidifier, the first solenoid valve and the second solenoid valve are controlled by the controller to open or close, the shunt refrigerating capacity can be adjusted, so that the temperature of heat exchange of the evaporator can be adjusted, therefore, according to the refrigerating capacity shunt system, the refrigeratingcapacity can be changed under the adjustment of the controller, the adjustment range is larger, and the refrigerating capacity shunt system is conductive to the pharmaceutical production and detection.
Description
technical field [0001] The invention specifically relates to a refrigerating capacity distribution system for pharmaceutical production equipment. Background technique [0002] The drug stability test chamber or constant temperature and humidity incubator in the biopharmaceutical equipment needs to be humidified during the drug production process, and the refrigeration system needs to be adjusted during the humidification process, which is convenient for the temperature environment of the high temperature test. parameters and performance. [0003] Most of the refrigeration systems in drug stability test chambers or constant temperature and humidity incubators used in conjunction with humidification systems in biopharmaceutical equipment are simple circulating water cooling or circulating air cooling methods. During operation, only a single heat exchange can be performed. , It is impossible to change and lower the temperature according to the needs of biopharmaceutical equip...
