What is constant temperature and humidity?
Maintaining a constant temperature for a long period of time for a specific purpose is called constant temperature, and maintaining a constant temperature and humidity is called constant temperature and humidity.
Temperature and humidity chambers are often used in universities, research institutes, and for the development and evaluation of industrial products. A chamber is a box-shaped container.
Purpose and reason for constant temperature and humidity environment
Why is a constant temperature and humidity environment necessary?
Let's list some possible purposes and reasons, divided into manufacturing processes and research and development.
Manufacturing Process
- Constant temperature and humidity ensure stable quality.
- Constant temperature and humidity stabilize production and shorten takt time.
- Constant temperature and humidity improves yield.
- The traceability of manufacturing conditions during the manufacturing process can be clearly established.
Research and Development
- In order to perform a correlation comparison between elemental technologies and data, environment must be the same.
- In order to keep the condition and properties of the raw materials the same, they must be stored in the same conditions.
- Physical property tests such as material tests must be carried out in the same environment, as stipulated by JIS and other standards.
- It is necessary to narrow down the mass production conditions from research and development data and extract the optimal conditions.
In addition, environment cycle testing, which involves repeated temperature increases and decreases at constant temperature and humidity, is also important to test the final performance of the product.
Types of temperature and humidity control equipment
There are various types of temperature and humidity control equipment, including thermostatic chambers.
Constant temperature chamber/constant temperature and humidity chamber
A constant temperature bath is a box-shaped container whose interior maintains a constant temperature and humidity, and is designed to prevent the effects of temperature changes from outside.
Anything larger than a box is sometimes called a temperature-controlled room.
A distinction is sometimes made between a thermostatic chamber that keeps only the temperature constant and a thermo-humidistat chamber that keeps both the temperature and humidity constant.
environment test equipment/ environment test chamber
This testing equipment simulates various weather conditions such as temperature and humidity and measures the changes that occur under these conditions.
Tests for corrosion may also be performed.
Constant temperature water bath
This device mainly uses a heater to heat the water in the tank and keep it at a constant temperature, and the temperature distribution is more stable than that of air.
The water temperature can be set between a few degrees Celsius above room temperature and up to 100 degrees Celsius, and is used for a variety of tests and analyses.
constant temperature dryer
This is a constant temperature drying chamber that uses a heater and a circulation fan to keep the temperature inside the chamber constant.
It has a wide range of temperatures and various programmable functions.
incubator
The word derives from incubator, and it is widely used in the fields of medicine and physical and chemical research, for culturing and preserving.
The low-temperature function is called a cool incubator, and is similar to a refrigerator.
environment Testing Machine
This testing machine measures the changes that occur in materials under these conditions. In addition to temperature and humidity, some testing machines also have the ability to test for climate and corrosion.
environment tests include environment cycle tests, temperature cycle tests, and temperature and humidity cycle tests.
<Temperature cycle test>
Checking the effects of temperature changes or repeated temperature changes on parts, equipment, or other products (JIS 0025).
<Temperature and humidity cycle test>
Repeated temperature changes between constant and low temperatures are applied to evaluate resistance to temperature changes and humidity in a short period of time (JISC 60068).
Japan is very long from north to south, and there are large temperature differences between regions.
Depending on the season, products are subject to a variety of climates and environment, from rainy seasons and hot and humid summers to scorching heat and harsh winters, so it is necessary to test the impact on products and their durability.
Simple and precise constant temperature and humidity room
To install and set up an environment testing chamber or a test/evaluation chamber equipped with a temperature and humidity control room, it is necessary to build it on a solid foundation. In addition, utilities must be prepared, and once set up, it is difficult to relocate it.
The more serious the system becomes, the greater the initial cost becomes, and it is not easy to install it at manufacturing site.
Therefore, we propose precision air conditioner (TCU/ECU) that can easily create precise constant temperature and humidity rooms at the desired site or floor.
