Cooling Temperature Controller
What is a cooling temperature controller? Cooling temperature controller is a kind of chiller, divided into air-cooled chiller and water-cooled chiller.
The cooling temperature controller is a water-cooled device that can provide constant temperature, constant current, and constant pressure. The principle of the equipment is to inject a certain amount of water into the water tank inside the machine, and the water is cooled by the refrigeration system. Then, the water pump inside the machine injects low-temperature chilled water into the equipment that needs to be cooled. The chilled water takes away the heat inside the machine, and the high-temperature hot water flows back to the water tank to cool down again. In this way, the cooling is circulated and exchanged, so as to achieve the effect of cooling the equipment. The cooling temperature controller is a typical closed-loop system with complete components including hot and cold water units, condenser and circulation pump, expansion valve, no-flow shut-off, internal cold water tank and temperature control station. The inside of the tank helps maintain cold water temperature and prevents temperature spikes. Cooling temperature controller Closed-loop recycling of conditioning additives or clean water at constant temperature and pressure improves stability and repeatability of water-cooled equipment and instrument cleaners.
If there is a large temperature difference between the incoming and outgoing water, then a large external tank is used to store cold water. In this case, the cooling water will not come out directly from the application of the chiller, but will go deep to the outside of the tank as a “temperature buffer sorting act”. The cold water tank is much larger than the internal tank. The application of cold water from the external tank and the return of hot water from the application can be traced to the external tank, not the unit.
The open loop control of the cooling temperature controller circulates in an open tank or pan to maintain the temperature of the fluid. Liquid comes from the storage tank, goes through the pump unit and returns to the storage tank. An adjustable thermostat senses the make-up fluid temperature.
One of the new developments in cooling temperature controllers is the use of air cooling instead of cooling water. In this case, the condenser is not cooled by hot air refrigerant but by cooling water using a cooling tower. This development allows more than 15% and, due to the large reduction of surface water in small areas, allows to reduce the energy demand of chillers, condensers and fans. In addition, the noise level is greatly reduced with the fan’s permission.
Most cooling temperature controllers are used for cooling, but some simple techniques that rely on air or water include the flow of cooling coils to regulate temperature. It is the most commonly used coolant in the freezing of water, although cooling mixtures (mainly containing coolant additives to enhance the heat dissipation of the water) are often used.
