Refrigeration system

The refrigeration system is one of the key components of the comprehensive Test Chamber. Generally speaking, the refrigeration methods are mechanical refrigeration and auxiliary liquid nitrogen refrigeration, mechanical refrigeration adopts vapor compression refrigeration, which is mainly composed of compressor, condenser, throttle mechanism and evaporator. If the low temperature of our test should reach -55 °C, it is difficult to meet the requirements of single-stage refrigeration, so the refrigeration method of constant temperature and Humidity Chamber generally adopts cascade refrigeration. The refrigeration system of the constant temperature and Humidity Chamber is composed of two parts, which are called the high temperature part and the low temperature part, and each part is a relatively independent refrigeration system. The evaporation of the refrigerant in the high-temperature part absorbs the heat from the refrigerant in the low-temperature part and vaporizes; The evaporation of the refrigerant at low temperatures draws heat from the cooled object (the air inside the chamber) to obtain the cooling capacity. The high temperature part and the low temperature part are connected by an evaporative condenser, which is both the condenser of the high temperature part and the condenser of the low temperature part. 

Heating system

The heating system of the Test Chamber is relatively simple compared to the refrigeration system. It is mainly composed of high-power resistance wires, because the temperature rise rate required by the Test Chamber is larger, so the heating system power of the Test Chamber is relatively large, and the bottom plate of the Test Chamber is also equipped with a heater. 

6. Temperature and humidity system

The temperature system is divided into two subsystems: humidification and dehumidification. 

The humidification method generally adopts the steam humidification method, that is, the low-pressure steam is directly injected into the test space for humidification. This humidification method has a high humidification capacity and fast humidification control, especially when cooling down, it is easy to achieve forced humidification. 

There are two types of dehumidification: mechanical refrigeration dehumidification and dry dehumidification. The dehumidification principle of mechanical refrigeration dehumidification is to cool the air below the dew point temperature, so that the water vapor greater than the saturated moisture content condenses and precipitates, so that the humidity is reduced. Dryer dehumidification is to use an air pump to pump out the air in the Test Chamber, inject the dry air, and at the same time send the moist air to the recyclable drying for drying, and then send it into the Test Chamber after drying, so that the cycle is repeated for dehumidification. At present, most of the comprehensive Test Chambers adopt the former dehumidification method, and the latter dehumidification method, which can make the dew point temperature reach 0 °C. It is suitable for occasions with special requirements, but the cost is more expensive. 

Sensor systems

The sensors are mainly temperature and humidity sensors. Temperature sensors are mostly used in platinum electric groups and thermocouples. There are two methods for measuring humidity: the psychrometer thermometer method and the solid-state electronic sensor direct measurement method. Due to the low accuracy of the wet and dry bulb method, the current constant temperature and Humidity Chamber is gradually replacing the wet and dry bulb with solid-state sensors for humidity measurement.
