The technology of production of quality plastic products on injection molding machines requires not only high-quality technological equipment, but also makes a number of requirements for meeting the requirements for removing heat from water and oil.
This section is devoted to optimizing the operation of thermal regimes of injection molding machines (injection molding machines, blow molding machines), namely, how to achieve particularly significant tasks:
All of the above tasks are achievable with the use or integration into an already operating Freecooler system or Dry Cooling tower or Draycler Green Box and IBC chillers.
Traditional scheme: Thermoplastic automatic - Chiller.
The system has the following drawbacks during operation:
General: 60 kW
The fricycle is switched off.
Integrated scheme A in the off-season : Thermoplast - Chiller - Frickler (dry cooling tower or drycooler) allows the chiller to be partially excluded from the working scheme during the off-season. As a result, during production, you get substantial savings, and taking into account the factors that Russia is mainly in the zone of 8-9 months of the year, low temperatures and only 3-4 the warmest seasons.
C Freckling during the off-season:
Integrated circuit A in winter: Thermoplast - Chiller - Frickler (dry cooling tower or drive cooler) allows the chiller to be completely eliminated from the working circuit in winter. As a result, during production, you completely exclude electricity costs.
The freezer is charged with a solution of ethylene or propylene glycol with a calculated freezing point.
C Freezing in winter:
Total: 10,4 kW
Friction: 150 kW
Integrated scheme A1 in the winter and inter-seasonal period : Thermoplast - Chiller - 2 contour Friculer (dry cooling tower or drive cooler). Friculer2 is filled exclusively with water.
The freezer is equipped with a drainage system. It operates in
automatic mode, when the ambient air is cold enough that it provides
preliminary cooling of the coolant in the freezer and reduces the operating
time of the chiller compressors.
When the system does not work or a scheduled emergency stop, in the absence of a heat load, the freezer automatically drains the water from the heat exchanger into the reserve tank to prevent it from freezing when the system runs on clean water without the addition of glycol.
The integrated circuit B2 with the use of two contour Friculler:
Cooling water and oil at the same time) and its advantages:
These systems are most effective for providing two independent temperatures and types of liquids for different consumers:
In each case, it is necessary to analyze the system in person, which requires cooling. For each case there is an optimal solution that allows to organize the optimization of the system taking into account energy saving and development.
To effectively cool industrial equipment, and in particular molds, freecooler is often used. In this case, the temperature of the coolant must be at least 30 degrees. Systems with freecooling at industrial enterprises are gaining momentum, as such measures significantly reduce the total energy costs. This becomes actual in the cold season, as such systems operate on the principle of replacing warm air indoors with cold from the environment.
Chillers equipped with a system of freecooling are monoblock refrigerators. Work with built-in air or water condenser.
Principles of the system:
Advantages of using a freecooler:
