Air-cooled scroll chiller
Air-cooled scroll chiller
The operation of the air-cooled scroll-type chiller system is through three interrelated systems: the refrigerant circulation system, the water circulation system, the electrical control system. Refrigerant Circulation System The liquid refrigerant in the evaporator absorbs the heat in the water and begins to evaporate. Finally, the temperature difference between the refrigerant and the water is formed. The liquid refrigerant is completely evaporated into a gaseous state and sucked and compressed by the compressor ( Pressure and temperature increase), gaseous refrigerant through the condenser (air-cooled / water-cooled) to absorb heat, condensed into a liquid. Through the expansion valve (or capillary) after the throttle into low-temperature low-pressure refrigerant into the evaporator to complete the refrigerant cycle process.
1, Water circulation system;
The pump is responsible for pumping water from the tank to the equipment that the user needs to cool, and the chilled water will take the heat away and then return to the chill tank.
2, Electrical control system;
Including the power section and the automatic control section. Power supply part is through the contactor, the compressor, fans, pumps and other power supply.
3, Automatic control part;
Including thermostat, pressure protection, delay, relay, overload protection and other combinations to meet the temperature according to the water temperature automatically start and stop, protection and other functions.
Generally more than 10P water-cooled cooling, 10P the following use of air-cooled cooling. Air-cooled industrial chillers are generally made for the whole machine, and evaporators, compressors and condensers. For slightly higher power air-cooled industrial chillers, you need to consider the work of the condenser cooling fan cooling problem. In the air-conditioning plant applications, the whole machine needs to set the exhaust duct will heat the fan blowing out of the outdoor.
Air-cooled scroll chiller can also be made into a split, the condenser directly into the outdoor (called outdoor unit), evaporator and compressor on the indoor (called indoor unit). However, considering the heat transfer between the condenser and the evaporator, the distance between the indoor unit and the outdoor unit is preferably controlled to 6 m, and the copper pipe for transporting the refrigerant needs to be insulated. Fan power supply cable and control cable can be wired with the brass to go, so that air-conditioned plant just through the hole can be.
For the application of small flow and small heat dissipation of air-cooled chiller industrial applications, the general use of the overall direct use, this time do not have to consider its cooling problem. For large flow and large heat dissipation of the air-cooled chiller, optional split. Air-cooled chiller cooling effect by the external environment of the seasonal climate change slightly affected, and water-cooled chiller, the use of water tower cooling effect is more stable, it is necessary to set the water tower, mobility is poor.
Chillers used in plastic processing machinery molding mold cooling, can greatly improve the surface finish of plastic products, plastic products to reduce the surface marks and internal stress, so that the product does not shrink, no deformation, easy plastic mold release, accelerate product stereotypes, so the pole The air to improve the production efficiency of plastic molding machine; air-cooled scroll chiller used in CNC machine tools, coordinate boring machine, grinding machine, machining center, the combination of machine tools and all kinds of precision machine tool spindle lubrication and hydraulic system drive medium cooling, Oil temperature, effectively reduce the thermal deformation of the machine to improve the machining accuracy of the machine.
This product uses a new original imported compressor, is Daikin Panasonic series, the product of the energy efficiency ratio higher. Condenser with vertical shell and tube design, evaporator copper tube with high efficiency internal thread copper tube, can effectively improve the thermal effect, cleaning is also convenient. Water pump selection Italy, Taiwan high flow high-lift pump, the use of safe ultra-quiet, power and use; body shell with electrostatic powder paint paint, nice; with stainless steel tank, easy to clean; Device that can be used to measure and control the water level, thus effectively saving customers time and improve work efficiency;
① Unit compact structure, small footprint, simple pipe design, only an external water pipe, easy installation and maintenance.
② Intelligent control, the unit can be based on changes in load, automatically adjust the input compressor output, so that the unit at any time to maintain the best efficiency with the best.
③ The use of imported fully enclosed scroll refrigeration compressor. With high efficiency, low noise, small vibration, reliable operation, long life and other advantages.
④ Microcomputer control system, with a strong security protection, communication, fault diagnosis, automatic adaptation and other functions; can automatically monitor the operation of the various parameters and operating conditions.
⑤ Unit integral and modular. Modular unit has 2 to 8 modules assembled, with a large amount of cold, alternate with each other, the gap running and so on.
⑥ Provide high and low voltage protection, chilled water anti-freeze icing protection, power phase sequence protection, lack of protection, water flow protection, compressor motor overheating and other multiple protection.
