Electric expansion valves

Type ETS 6

The range of Electric expansion valves are based on many years of experience. ETS 6 secure reliability and provide a precise solutions for ex pansion and ﬂow control in a wide range of refrigeration and air conditioning systems.

Compact and lightweight. The current range is available with a wide capacity range, and can be used with all common ﬂuorinated refrigerants. Bi-ﬂow operation is also possible for heat pump systems.

The valve operation is by means of a uni-polar motor, which can be controlled by a number of controllers from Danfoss or third party vendors.

With an EKE 1V and EIM 336 (current drivers) and an AKS sensor, an accuracy better than

± 0.5 K can be obtained.

Please contact Danfoss for more details.

Features • Optimized energy eﬃciency of the system.

• Precision ﬂow control with high resolution.

• Compact and lightweight.

• Energy saving design.

• Proven know-how and high reliability.

• Wide range for all common refrigerants.

• Bi-ﬂow for heat pump applications.

Tested for 60 Million total pulses supplies to the valve during partially open valve, which is comparable to 150,000 cycles if the valve is operated between 100 to 300 pulses open. Tested for 30,000 full stroke cycles including 20 pulse overdrive at each closing.

0 to 480 pulses, no holding power required (NOTE: do not apply more than 520 pulses).

With coil on the upper side and the valve/coil assembly within ±15˚of the vertical axis If using a liquid line solenoid valve, it must be installed in such a way that it does not create liquid hammering this ETS 6 valve.

Design/function

The ETS 6 Electric expansion valves open and close to regulate refrigerant ﬂow by means of a screw, whose rotating motion is transformed into linear motion. This occurs by the rotation of a magnet-needle valve assembly which moves when electrical signals are applied to the surrounding coil.

Within the coil structure, there are diﬀerent winding conﬁgurations, and the

Needle valve

Valve body

polarities are changed by the electrical signals applied. By application of the appropriate combination of signals, in the form of pulses, the coil forces the rotor of the valve to move in a stepwise fashion.

Application of multiple pulses will make the valve mechanism to move through a series of steps in the chosen direction, in order to set the valve with the required opening degree.

Example

For optimum performance, it is important to correct the evaporator capacity. In order to select the correct size of ETS 6 you will need the following information:

When selecting the valve it may be necessary to apply a correction factor to the actual evaporator capacity. This correction factor is required when system conditions are diﬀerent than table

conditions. Selection also depends on having an Refrigerant: HCFC / HFC Evaporator capacity Qe in kW or TR Evaporating temperature te in °C / °F Condenser temperature tc in °C / °F Subcooling Δt

in K / °F

sub

acceptable pressure drop across the valve. In the

selection table, the pressure drop in the liquid

line is assumed to be zero. The following example

illustrates correct selection of the valve.

Refrigerant: R407C

Evaporator capacity: Qe = 10 kW / 2.84 TR

Condensing temperature: tc = 40 °C / 104 °F

Evaporating temperature: te = +10 °C / 50 °F

Subcooling Δt

= 10 K / 18 °F

sub

Note!

Coolselector®2 is a Danfoss calculation and selection software designed to make selection processes for all refrigeration

projects easier and less time consuming. For details refer http://coolselector.danfoss.com

Step 1

Determine the correction factor for subcooling Δt

. From the correction factor table (see below)

a subcooling of 10 K, R407C corresponds to a factor of 1.14.

Step 4

Choose ETS 6 -18:

• Single pack code no. 034G5026

Qe (Corrected) = 10 kW /1.14 = 8.8 kW / 2.5 TR

• I-pack code no. 034G5024

Step 3

Select the appropriate capacity table, R407C, and choose the column for condensing temperature of tc = 40°C / 104 °F and evaporating temperature of te = 10°C / 50 °F which will provide an equivalent or greater capacity of 8.8 kW / 2.5 TR. ETS 6 - 18 provides 10.35 kW / 2.94 TR, which is the proper selection for this example.
