In April 2020, Aowei Instruments Green Lab series products (solvent safety bottle caps, intubation type waste collection, funnel type waste collection) received good sales news one after another. Among them, a teacher from a laboratory in Sichuan found us and thought To solve the problem of waste water collection during the use of its solid phase extraction equipment, it was precisely because of the green laboratory products of Aowei Instruments, that we immediately contacted us.
In April 2020, Aowei Instruments Green Laboratory Solution Products (solvent safety bottle caps, intubation type waste collection, funnel type waste collection) again contributed to the green environmental protection of major laboratories in China. Not long ago, a laboratory in Southwest China found us to solve the problem of liquid chromatograph waste.
In September 2019, the solvent recovery instrument produced by Aowei Instruments (Tongzhou Weipu) played a vital role in the tea extract determination experiment process of a large enterprise, because the intervention of this solvent recovery instrument not only It has helped the entire experiment to proceed smoothly, and also protected other equipment involved in the experiment, prolonged its service life, and virtually helped the company save costs. This is a win-win cooperation with multiple objectives.
Industrial chillers are widely used in industry. It can be seen that the current development of industrial chillers is very good, what about the future development?
The normal and safe operation of the chiller is inseparable from the refrigerant. So what factors should we consider when choosing a refrigerant?First, thermodynamic performance
For the two-stage compression used to obtain low temperature industrial chillers, it is important to choose which intermediate cooling method is used, and the choice of cooling method depends mainly on the temperature of the exhaust gas.
The cooling water temperature is higher, the condensation effect is poor
Conventional industrial chiller cooling water must be maintained between 30 and 35 degrees to maintain stable operating performance. If the temperature of the cooling water is high, or there is a serious problem of heat dissipation, the pressure of condensation will inevitably increase. Especially in many high temperature seasons, special attention should be paid to heat dissipation problems. Poor heat dissipation is very harmful to industrial chillers.
