Electrically operated expansion valves, type ETS

1 MAKING MODERN LIVING POSSIBLE Technical brochure Introduction ETS is a series of electrically operated expansion valves for precise liquid injection in evaporators for air conditioning and refrigeration applications. The valve piston and linear positioning design is fully balanced, providing bi-flow feature as well as solenoid tight shut-off function in both flow directions. The ETS needs a current or voltage driver as partner to be operated. EKC316A, 312 and EKD316 are examples of Danfoss controllers with drivers matching the ETS needs. The ETS design is being registered. The pending reference number is Features Precise positioning for optimal control of liquid injection. ETS 12,5, ETS 25, ETS 50 and ETS 100 are designed for HFC/HCFC conditions including R410A, providing 45.5 bar (659.9 psig) working pressure. ETS 250 and 400 are designed for HFC/ HCFC conditions, providing 34 bar (493 psig) working pressure. Balanced design providing bi-flow operation as well as solenoid tight shut-off function in both flow directions at MOPD 33 bar (48.6 psig). EKC316A, 312 and EKD316 are examples of Danfoss controllers with drivers matching the ETS needs. ETS 50 and 100 have bi-metal connections providing "waterless brazing", improved process and productivity. ETS 50 to 400 are all designed with built-in sight glass. Cable and connector assemblies as accessories. For manual operation and service of ETS valves an AST-g service driver is available. For further information please contact Danfoss.

Cone andlead nut Product type ETS File name 34G46 Date Valve operation Danfoss 93G18.13 ETS The ETS valves operate modulating by electronically controlled activation of the AST stepper motor. The motor is a type 2-phase bi-polar, which stays in position, unless power pulses from a driver initiate the two discrete sets of motor stator windings for rotation in either directions. The direction depends on the phase relationship of the power pulses, which number again is decisive for the travel. The motor is operating the spindle, which rotating movements are transformed into linear motion by the transmission in the cage assembly. ETS design is fully power balanced, giving identical bi-flow performance capabilities and nearby identical maximum capacities. The port design includes a shut-off function with "solenoid" tightness in both flow directions. Closed position is also the mechanical stop acting as reference point to reset the controller. Operating the ETS series requires a controller with either 12 V dc voltage drive (5.5 W) or using chopper drive (100 ma RMS). Danfoss EKC316A, EKC312 and EED316 are examples of qualified controllers. The AST motor housing has a glass sealed M12 connection as standard, which can be connected with customized cable and plug/socket combinations. DKRCC.PD.VD1.C2.02 / 520H5239 3

4 Valve operation (Cont.) Note: Depending on the type of controller or rather driver, there will be limitations in cable length between valve actuator and driver. Both the actual cable length, the level of EMC emission on the location and driver circuit has an impact on the actual distortion of the current to the actuator motor. For the Danfoss controllers the rule of thumb is maximum 5 m [15 feet] for EKC316 and 312 and 50 m [150 feet] for EKD316. In all these controllers a 10 mh filter type AKA 211 can be installed on the four power terminals that can increase the maximum cable length considerably. Please contact Danfoss for further information how and when to apply this countermeasure in cases with questionable cable length.

5 Sizing Correction for subcooling t sub The evaporator capacity used must be corrected if subcooling deviates from 4K (.2 F). The corrected capacity can be obtained by dividing the evaporator capacity by the correction factor given below. Note: Insufficient subcooling can produce flash gas.

Under the given circumstances ETS 100 can operate between 496 kw (142 TR) and 56 kw (14 TR). Bi-flow capacities (opposite of normal flow direction) are the same for ETS 50, whereas ETS 100 has 10% less from normal flow direction.
