The concept of water chiller is still quite new to many people, but this is an indispensable and indispensable equipment in today’s chiller industry. Application of water chiller water chiller appeared in the food industry, pharmaceutical, medical, electronic …
Water chiller is an industrial water chiller with a water temperature of 6 ° C to 30 ° C (normal water temperature is 30 ° C).
Cold water is created mainly for demand such as:
Supply cold water for Concrete Mixers.
Refrigeration chemical blends.
Applications for food industry: alcohol, beer, beverage.
Used for plastic plant, color printer cooler, oil cooler precision machine through PHE plate.
For water temperature range from 7 degrees C to 12 degrees C, suitable for bookstore, supermarket, workshop space. In addition, it is suitable where there is a need for fresh air for the workplace environment such as shopping malls.
Principle of operation water chiller
Application of physical state change: condensed water vapor, liquid condensed into solid.
Solids converted into liquid, chewers changed to gases, the process will collect heat: take heat from the surrounding environment and make that environment lose heat and cool. Conversely, that process will radiate heat.
The cooling system applies a basic principle of evaporation to collect heat around the environment and make it cooler.
The opposite process occurs after that: low pressure steam is compressed from the compressor. The cooled steam pressure from the cooling tower or the copper tube blowing through the heat collector with the help of the compressor converts it completely into a closed loop. Between gas and gas is adjusted by throttle.
For water cooling chiller
It consists of 4 main parts: cold compressor, outdoor unit, indoor unit, control cabinet.
The chiller is a straight copper pipe from one end of the pipe to the other, the water inside the copper pipe, the condensed gas that is contained in the condenser, and the liquid to be absorbed from the water to the cooling tower.
Evaporators have three types: dry evaporator, evaporator evaporator and evaporator with stainless steel plate.
Dry evaporation: the water passes through the vase, the gas evaporates inside the copper pipe, thanks to the water table, the water flows in sinusoidal form, increasing the flow of water and increasing the heat exchange efficiency.
Steam flow: applied with a capacity of 100 tons or more with much higher efficiency than dry type. Then the coolant boils outside the tube while the water flows in the copper tube. The evaporator is insulated and maintained at a temperature not to exceed 7 ° C to prevent the freezing of the water from exploding.
For wind chillers
It is similar to water chiller but has some differences:
Do not use cooling tower cooling towers that exchange heat from high-pressure hot air with the air from the exhaust fan.
This type of performance is much worse than the water-cooled chiller.
However, due to special conditions people still use wind chiller.
In terms of structure only the water cooler chiller is not using condenser chillers that use aluminum coil pipe.
Water chiller water chiller is very important in enterprises, enterprises today because of its application.
