Chillers are used for cooling / cooling to ensure good refrigeration performance of the unit. And in some chiller related books or related knowledge literature, you often see some model labels, and what do these model labels mean? Next, Dongguan Guansheng Machinery Co., Ltd. will explain the meaning of some common model labels for everyone, LS is the abbreviation of chiller; Compressor form: B-semi-closed, Q-fully closed, open type is omitted; compression Method: LG-twin-screw type, DG-single-screw type, W- scroll type, piston type is omitted: Function code: R- heat pump type unit, single-cooled type unit is omitted; cooling form: F-air-cooled type, water-cooled Omit; nominal cooling capacity of the unit: unit: kw; BP refers to variable frequency compressor.
The chiller is also called a freezer. It has two types: water-cooled and air-cooled. The water-cooled refrigeration effect is better, but it needs cooling water. The air-cooled type is flexible and convenient. The newly launched ACH ice-heat dual-purpose machine has a wide range of applications in the field of low temperature and high precision temperature control.
The composition of the chiller includes: 1. compressor; 2. pump; 3. computer PC board with touch control for safety and convenience; 4. temperature controller: liquid crystal display temperature control electronic board; 5. expansion valve and filter; 6. Built-in 304 stainless steel water tank covered with heat-insulating material; 7. LG Electronics in South Korea; 8. Safety protection system, and the so-called safety protection system includes the following aspects, which are compressor delayed start protection and refrigerant high pressure Safety valve, poor cooling protection and indicator, fault alarm buzzer, ice water pump overload and indicator, compressor overload protection, motor reverse protection and indicator, compressor overload protection and indicator, refrigerant shortage protection and indicator and many more
