Air Cooled Scroll Chiller

Transcription

1 ir ooled Scroll hiller Midea chillers use V shape heat exchanger and single unit s capacity from 30kW to 250kW.They are divided to PS, PS-L,PS-HM and PS-HML series according to their operation ambient temperature and inner components. PS-L Product Lineup apacity (kw) ppearance Series 250 series are products with low ambient temperature cooling function and PS-HM series are products built-in with hydraulic module.ps-hml series are products built-in with hydraulic module based on PS-L products. 50Hz PS (/) / / / / / 50Hz PS-L(/) / / / / / 50Hz PS-HM(/) / / / / / 50Hz PS-HML (/) / / / / / 60Hz PS (/) / / / / / PS: Standard Power Series PS-L: Power Series with low ambient temperature cooling function PS-HML: Power Series with low ambient temperature cooling function and built-in with hydraulic module PS-HM: Power Series built-in with hydraulic module : Product adopted fixed speed scroll compressor : Product adopted digital scroll compressor 09 10

2 eatures Wide application 19 basic models with cooling capacity ranging from 30kW to 250kW, combination model s maximum capacity ups to 2000kW. Max 8 modules dvanced technology igital scroll technology The digital scroll compressor utilizes axial compliant sealing technology to precisely adjust the axial motion of the stator scroll pan. nd there is an additional connecting by-pass between the suction inlet and the pressure bore at the floating sealing point of axial stator. PWM valve Provides 40 million times the average service life of PWM 250kW 250kW 2000kW reely combine with fan coil units and air handling units. Project owners may choose the best types according to their design taste (for interior) or functional needs. ischarge ixed Scroll Suction Orbiting Scroll solenoid valves, making sure the long life of compressor. Guarantees high efficiency by applying axial-compliant sealing technology. Inverter M Regulation igital Scroll System mpere 5th 7th loor standing assette type ir handling units Provides 10% to 100% stepless capacity output to precisely control room temperature. Less electromagnetic interference, no M problem. Operation Principle of igital Scroll ompressor 11th 13th 17th 19th MW Wide operation ambient temperature or the chillers with low ambient temperature cooling function, the running ambient temperature down to -10 both in cooling and heating. 46 elling & loor Wall mounted uct type 24 When the PWM solenoid valve is open, the pressure in the pressure bore is released. The pressure in the compression bore is higher than that top of the stator, then the stator axis of the compressor will move upward a little. So high pressure bore and low pressure inlet is connected and the unloading is achieved. When the PWM solenoid valve is closed, two stators engage to achieve an airtight state and loading functionality. The compressor can adjust the ratio of ON to O freely to control the refrigerant output of the compressor. OOLING HTING High reliability in high ambient temperatures is guaranteed by the low pressure design of the compressor motor ffectively cools the compressor motor by suction gas. Wide of outlet water temperature or the chillers with low water outlet temperature function, the lowest outlet temperature in cooling mode is ischarge Suction ompressor motor reates stronger resistance to the compressor liquid hammer. Provides strong reliability in high ambient temperatures. OOLING MO HTING MO 11 12

3 High performance heat exchanger Reduce air resistance lexible installation uilt-in hydraulic module MGSL- () 30W/RN1and MGS- () 30W/RN1are equipped with a hydraulic module integrated into the unit chassis, limiting the installation to straight-forward operations like connection of the power supply, the water supply and the air distribution terminals. New design The new designed window fins enlarge the heat-exchanging area, decrease the air resistance, save more power and enhance heat exchange performance. Hydrophilic film fins and inner-threaded copper pipes optimize heat exchange efficiency. The specially coated blue fins enhance durability and protect against corrosion from air, water and other corrosive agents, assures a longer coil service life. ack-up functions In a combination system, if one module failed, other modules can be back-up instead of the failed one for continuing operation. Master Original design Slave High efficiency inner-threaded pipe, enhance heat transfer. Hydrophilic fins + inner-threaded pipes Master Slave Individual hydraulic module optional Individual hydraulic module compatible with cooling capacity of 65kW and 130kw is optional. Water box, expansion water tank, two water pumps are built in the hydraulic box. The integral structure design saves you much installation labor and cost. asy control Touch key wire controller as standard accessory to control the chillers. HM/II-65S HM/II-130S ompliance with rp directive 30kW and 65kW products are compliance with rp directive, including both PS series and PS-L series. The seasonal space heating energy efficiency classes for 30kW models are rated and 65kW models are + rated. Remote control functions for convenient operation. There are ON/O, Heat/ool and larm terminals ports on P, connect switches from these terminal ports and remote control functions can be easily realized. Note: When use the remote control function, the wired controller will be invalid for ON/O and mode selection
