Earth-friendly and efficient cooling screw refrigerator RSU-R602TFV
Kulow System Co., Ltd.
About This Product
Features
■Improved efficiency [Air-cooled type (outdoor installation type)]
Equipped with a new high-performance inverter compressor
①Improved efficiency by optimizing the low/high stage discharge rate ratio
②Improve efficiency by optimizing internal volume ratio
③ High-precision rotor reduces internal leakage and improves efficiency
(compared to our company)
■Improved operability and serviceability by adopting a liquid crystal touch panel
Adoption of LCD touch panel (refrigerator information is displayed on the LCD screen)
■Two modes can be set depending on the application
For "suction pressure control" and "interior temperature control", mode switching is possible using external input signals. Please use this when switching the setting values such as "pre-cooling (set temperature inside the refrigerator -20℃)" and "freeze (set temperature inside the refrigerator -40℃)".
■Frequency control
We have prepared four types of frequency control methods to accommodate a variety of uses. (Selected by switch on printed circuit board)
■Suction pressure control
The cooling load is determined based on the detection value of the suction pressure sensor built into the refrigerator, and the compressor rotation speed is continuously controlled.
・Area 1: Increase the operating frequency based on the inverter load factor
・Area ②: Maintain operating frequency
・Area ③: Reduce operating frequency
■Interior temperature control
The temperature inside the refrigerator is input as a 4 to 20 mA DC signal from a temperature controller prepared on site to the refrigerator control panel, the cooling load is determined, and the compressor rotation speed is continuously controlled.
・Area 1: Increase the operating frequency based on the inverter load factor
・Area ②: Maintain operating frequency
・Area ③: Reduce operating frequency
■External contact control
A non-voltage contact signal prepared on site is input to the compressor control panel to control the compressor rotation speed in three stages. Stepwise control is performed to vary the compressor rotation speed from "Stop - Frequency ① - Frequency ② - Maximum frequency" according to the open/close status of the non-voltage contact signal from control equipment prepared on site.
■Proportional control
The operating frequency is continuously controlled by an external DC4 to 20mA current signal.
■Noise filter available as an option
A noise filter for the inverter is available as an option. Regarding noise countermeasures, please take measures on-site as necessary. As an option, it is also possible to ship a noise filter built into the product.
