The application of chillers in the chemical industry has been extremely frequent, especially the application of chemical chillers to the cooling of plastic processing machinery molding molds, which can greatly improve the surface finish of plastic products, reduce the surface marks and internal stress of plastic products, and make the products do not shrink or not. Deformation facilitates the demoulding of plastic products and accelerates product shaping, thereby greatly improving the production efficiency of plastic molding machines. However, for novice users of chemical chillers, what is the refrigeration of chemical chillers? The following is a brief discussion by the chiller manufacturer.
A chemical chiller typically comes as a complete packaged closed loop system, including the chiller, condenser and circulating pump, expansion valve, no-flow shut-off, internal cold water tank, and temperature control station. Internal tanks help maintain cold water temperatures and prevent temperature spikes. Closed-loop chemical chillers recirculate water at constant temperature and pressure for increased stability and repeatability in cooling equipment and instrument cleaners with conditioned or clean water. The cooling of the water flow is applied to the angle of use and back.
If there is a high temperature difference between the inlet and outlet water, the large external tank will be used to store cold water. In this case, the cooling water does not come directly from the cooler application, but rather deep into the outside of the tank acts as a sort of "temperature buffer. The cold water tank is much larger than the internal water tank. Cold water from the external fuel tank application" And when returning hot water from the application it can be traced back to the external fuel tank, not to the unit.
The less common open-loop control of industrial refrigerators is in an open tank or sump which continuously circulates the temperature of the liquid. The liquid is from the tank, through the pump unit, and back into the tank. An adjustable thermostatic sensory make-up liquid temperature circulates the cooler to maintain a constant temperature in the tank.
One of the new developments in chemical chillers is the use of air cooling instead of cooling water. In this case, the condenser is not cooled with hot air refrigerant, but is used by cooling water from the cooling tower. This development allows over 15%, and allows for a significant reduction in energy demand due to the small area of ​​surface water coolers, condensers and fans. In addition, noise levels have been drastically reduced where fans allow.
Most industrial chillers use a cooling medium for cooling, but some rely on simple technologies such as air or water that involve the flow of cooling coils to regulate temperature. Water is a commonly used coolant in freezing processes, although cooling mixtures (mainly water with coolant additives to enhance heat dissipation) are often employed.
