ویژگی های چیلر های هوا خنک
چیلرهای هوا خنک اسکرو (Air Cooled Screw Chiller) به دلیل استفاده از فناوری کمپرسور اسکرو و خنک سازی با هوا، مزایای قابل توجهی نسبت به سایر چیلرها دارند. در اینجا برخی از مهمترین این مزایا ذکر شده است:
- بازدهی بالا (High Efficiency): چیلرهای هوا خنک اسکرو با بهره گیری از کمپرسورهای اسکرو، بازدهی انرژی بالایی دارند و در نتیجه مصرف برق را کاهش می دهند.
- ابعاد مناسب (Compact Size): این چیلرها به دلیل طراحی بهینه، ابعاد نسبتا جمع و جورتری نسبت به سایر چیلرها دارند که باعث سهولت در نصب و اشغال فضای کمتر در موتورخانه می شود.
- کاهش صدا (Lower Noise): با استفاده از فن های آکسیال دور پایین و طراحی کم صدا، این چیلرها نویز کمتری تولید می کنند.
- هزینه نگهداری پایین (Low Maintenance Cost): چیلرهای هوا خنک اسکرو معمولا قطعات متحرک کمتری دارند که این امر موجب استهلاک کمتر، سهولت در تعمیر و نگهداری و در نتیجه کاهش هزینه های مربوط به آن می شود.
- کنترل هوشمند (Intelligent Control): این چیلرها اغلب از کنترلرهای هوشمند PLC بهره می برند که امکان مدیریت دقیق عملکرد دستگاه، تنظیم دما و عیب یابی آسان را فراهم می کند.
- ظرفیت بالا (High Capacity): چیلرهای هوا خنک اسکرو قابلیت تامین سرمایش برای فضاهای بزرگ و صنعتی را دارند.
به طور کلی، چیلرهای هوا خنک اسکرو گزینه ای مناسب برای پروژه هایی هستند که به دنبال راهکاری با بازدهی بالا، کم صدا، کم مصرف و با نگهداری آسان برای تامین سرمایش مورد نیاز خود می باشند.

Economizer
• An economizer is a type of sub-cooler that uses part of the total refrigerant flow from the condenser to cool the rest of the refrigerant flow.The evaporated refrigerant then enters the compressor at an intermediate pressure level.The cold gas from the economizer can also be used to provide extra cooling
The Screw liquid chillers have a screw compressor with R-134a
refrigerant on two separate refrigeration circuits.
■ TWO INDEPENDENT CIRCUITS – Both refrigeration circuits adopt
compact screw compressors, for maximum reliability and durability.
■ EFFICIENT AND RELIABLE TECHNOLOGY – employs dual screw compressors, electronic expansion valves, shell and tube
evaporator and fans with low noise diffusers with economizer for increasing efficiency
