How to achieve constant temperature in a constant temperature and humidity laboratory

The vast majority of tests can be carried out in the laboratory at room temperature, some of the tests with temperature control regulations, usually the testing instruments have their own test solution chamber, if the test must be carried out in the laboratory with temperature control regulations, it should also be a small temperature control room, and the temperature of all laboratories should not be adjusted
back and forth.
The constant temperature and humidity laboratory specifies the appropriate temperature/ambient humidity
.
The microclimate in the room, including average temperature, ambient humidity and cyclone rate, is often harmful
to the staff and experimental instruments working in the laboratory.
Different seasons have different rules
.
The suitable temperature should be 18 ~ 28 °C in summer, 16 ~ 20 °C in winter, and the ambient humidity zui hao is in the middle
of 30% (winter) to 70% (summer).
The control level of the natural environment standard temperature and humidity takes into account the factors that ensure that the natural ambient temperature and humidity of the experimental process can meet the requirements
of each whole process of the experimental procedure.
It is important to formulate the scope of temperature and humidity manipulation in the natural environment of
the laboratory from the following multiple levels.
First, identify the requirements of each task for the temperature and humidity of
the natural environment.
The key identification of experimental reagents, the personalized consideration of laboratory staff, the necessity of instruments and equipment and the necessity of test procedures, four factors are fully considered, and the details of the scope of temperature and humidity manipulation are listed
.
Second, select and formulate a reasonable natural environment temperature and humidity control category
.
The steep category is removed from the list of all factors as the allowable scope of the natural environment manipulation of the laboratory, and the management procedures at the level of the manipulation level of the natural environment standard are formulated, and an effective and reasonable SOP
is formulated according to the specific conditions of the department.
After that, according to the intelligent control system, ensure that the temperature and humidity of the natural environment are within
the range of manipulation.
Select the air conditioner soft starter to adjust the air conditioning cooling capacity, after the temperature equalization, the computer online tracking and calculation of the size of the heat generation must be filled, change the working voltage of the electric heater, exceed the effect of changing and manipulating the output power of the electric heater, so that the index value in the test room is not subjected to the external and room interference sources, exceeding the temperature balance
