Air conditioning system of low-temperature laboratory

Abstract

The invention provides an air conditioning system of a low-temperature laboratory. The air conditioning system comprises an air conditioning device, a temperature control unit, a refrigerating device, an electric control box, a temperature and humidity sensor and the like. The temperature and humidity sensor is used for monitoring the temperature and humidity in the low-temperature laboratory in real time, when the real-time temperature and humidity deviate from preset values, the electric control box regulates and controls an electromagnetic valve in the air conditioning device and also regulates and controls an electromagnetic valve in the temperature control unit at the same time, and temperature and humidity regulation and control are more accurate through two times of regulation and control. Meanwhile, under the action of the air supply cavity and the air supply pore plate, air flow is stably supplied into a working area of the low-temperature laboratory, and an air return opening of the air return cavity is formed in the bottom, so that an air flow organization type of top air supply and lower air return is formed, and the constancy of the temperature is ensured. Compared with an existing air cooler cooling mode, the indoor constant-temperature constant-humidity and low-noise design environment is achieved, and high comfort of personnel is guaranteed.

Description

technical field [0001] The invention relates to the technical field of ship air conditioning, in particular to an air conditioning system for a cryogenic laboratory. Background technique [0002] Ships have cabins with special requirements on temperature and humidity, such as cryogenic laboratories, which have extremely precise requirements for temperature and humidity control. The system only uses a separate cooling fan for cooling, and the accuracy is controlled by the temperature sensor set on the cooling fan. Because the cooling fan is arranged in the corner of the low-temperature laboratory, it is easy to cause the internal temperature imbalance, which seriously affects the accuracy of the experiment with extremely high requirements on the experimental temperature. At the same time, when the personnel in the cryogenic laboratory are working normally, the direct blowing of the cooling fan not only affects the experimental work of the personnel, but also makes the comfor...

Problems solved by technology

Because the cooling fan is arranged in the corner of the low-temperature laboratory, it is easy to cause the internal temperature imbalance, which seriously affects the accuracy of the experiment with extremely high requirements on the experimental temperature.

At the same time, when the personnel in the low temperature laboratory are working normally, the direct blowing of the cooling fan not only affects the experimental work of the personnel, but also makes the comfort of the personnel extremely poor.
