With the progress of science and technology, more and more venues need high-precision constant temperature and humidity air conditioning.At present, some universities and enterprises have precision laboratories, data center machine rooms, power distribution of the State Grid, precision instrument processing workshops, and plant culture environments in agriculture. The characteristics of precision air conditioning are constant temperature and humidity, timely feedback and self-tuning to cope with load fluctuations.
Precision air conditioners generally use indirect refrigeration, which controls thermal fluctuation with small temperature difference. In particular, PID regulation can be realized in control. Combined with frequency conversion control, indoor air outlet temperature and humidity will be stable to meet high process requirements.With the economic development of the north, its demand for compact air conditioning is also gradually increasing. However, in the mode used in the south, there is a risk of pipeline freeze damage in the north. Some air-conditioning manufacturers have adopted the antifreeze solution on the market to solve the antifreeze problem.However, with the long-term use, it is found that the stability of the system has decreased. The main reason is that the physical properties of the antifreeze are unstable.It is necessary to calculate the selection of equipment in the design stage of precision air conditioning, and the physical parameters of coolant are essential.The main function of antifreeze in the market is antifreeze. There are few physical property tests, and it is corrosive after a long time. Rust mud will accumulate at some heat exchangers or regulating valves, affecting regulation and heat exchange, resulting in instability of the air conditioning system.
Glacial Coolant is specialized in making coolant,It has been used in many and stable fields, such as medicine and chemical industry. It is a product developed in the industrial field.Upgrade high-end testing software such as physical property testing laboratory, mass spectrometer and chromatograph, and provide high-quality after-sales service.When the precision air-conditioning system studies the control to improve the accuracy, it needs to pay attention to some external conditions of the coolant, so as to achieve more stable high-precision control.
