(Explanation: The air-cooled chiller in the picture uses a shell and tube evaporator to exchange heat between water and refrigerant. After the refrigerant system absorbs the heat load in the water and cools the water to produce cold water, the heat is evaporated through the action of the compressor. It is brought to the fin condenser and then dissipated to the outside air by the cooling fan (wind cooling)
Figure Water-cooled chiller uses a shell and tube evaporator to exchange heat between water and refrigerant. The refrigerant system absorbs water After cooling the water to produce cold water, the heat is brought to the shell and tube condenser through the action of the compressor. The refrigerant and water perform heat exchange, so that the water absorbs the heat and then takes the heat out of the external cooling tower through the water pipe for dissipation. (Water cooling))
As shown in the figure, the compressor initially sucks in the low-temperature and low-pressure refrigerant gas after evaporation and refrigeration, and then compresses it into high-temperature and high-pressure gas and sends it to the condenser. After the high-pressure and high-temperature gas is cooled by the condenser, the gas is condensed into Normal temperature and high pressure liquid When the normal temperature and high pressure liquid flows into the thermal expansion valve, it is throttled into low-temperature and low-pressure wet vapor, flows into the shell and tube evaporator, absorbs the heat of the frozen water in the evaporator, causes the water temperature to drop, and the evaporated refrigerant is then sucked back into the In the compressor, the next refrigeration cycle is repeated
: The first method:
The water-cooled chiller can be equipped with tons of clamping force. The temperature of the injection molding machine is controlled at ℃
The water-cooled chiller can be equipped The temperature of the injection molding machine with a ton clamping force is controlled at ℃
The water-cooled chiller can be matched with the injection molding machine with a ton clamping force. The temperature of the injection molding machine is controlled at ℃
(The matching air-cooled chiller is a water-cooled chiller. times, that is, the temperature of the air-cooled chiller with a ton clamping force of the injection molding machine is controlled at ℃.)
The second method:
The water-cooled chiller can be equipped with a single injection molding volume of The machine temperature is controlled at ℃.
Injection volume.
The above formula is the result summarized by sutras. In addition to using the above formula, the actual situation should be considered to select the appropriate chiller.
: Matching of chiller and cooling water tower,
According to past actual experience, a chiller needs to be equipped with a cooling water tower with a ton of cooling capacity to take away the heat generated by the chiller.
