MAKING MODERN LIVING POSSIBLE
The TE ries expansion valve regulate the injection of refrigerant into evaporators. It controls the refrigerant flow bad on the superheat. The exchangeable power element is produced with the well known Danfoss lar welding technology for extended lifetime capability. The TE ries is available with a wide range of orifices which will cover a wide range
of applications.

Identification
新东方邮箱Element label
Orifice asmbly marking
for TE5 to TE55
The thermostatic element is fitted with a label (on top of the diaphragm). The code refers to the refrigerant for which the valve is designed:X = R22N = R134a
S = R404A/R507Z = R407C
The label holds information like valve type, evaporating temperature range, MOP point, refrigerant, and max. test pressure, PS.Orifice asmbly for TE5, TE12, 20 and 55
The orifice asmbly is marked on top of the spring cup, e.g. as shown in the figure.For a given size of valve, the same orifice
asmbly can be ud for valves with ranges N and B.
TE12 = For valve type 05 = Orifice no.
067B2708 = Orifice code no. for sales order 1009 = Production date (Week, Year)
Capillary tube tag for TE5 to TE55
The label gives the orifice size (04). A new label always accompanies a new orifice asmbly.

Max. temperature
Bulb, when valve is asmbled: 100°C
Complete valve when not asmbled: 70°C
SS = static superheat OS = opening superheat
SH = SS + OS = total superheat Q nom = rated capacity
Q max = maximum capacity
Static superheat SS can be adjusted with tting spindle.
The standard factory superheat tting SS is 4 K.The opening superheat OS is 4 K from when opening begins to where the valve reaches its rated capacity Q nom .
Superheat
Example
Static superheat SS = 4 K Opening superheat OS = 4 K Total superheat SH = 4 + 4 = 8 K
Using orifice with range B element, plea check superheat under running conditions and re-adjust superheat tting, if necessary.
Min. temperature: –60°C Max. test pressure: 32 bar
Maximum working pressure:
28 bar

Design/Function
General
All TE valves have an interchangeable orifice asmbly.
TE5 to TE55 valves are built up of three main components:
1 - Thermostatic element
omg2 - Orifice asmbly
3 - Valve body with connections
The orifice is refrigerant and range independend.
All valves are equipped with external pressure equalization.
To ensure long operating life, the valve cone and at are made of a special alloy with particularly good wear properties.
1. Thermostatic element (diaphragm)
2. Interchangeable orifice asmbly
3. Valve body
4. Superheat tting spindle (e instructions)
5. Ext. pressure equalizing connection with 1⁄4 in./6 mm flare nut

Capacity in kW, range N, -40°C to +10°C, opening superheat sh= 4 K Q (capacity) = 45kW
Tcon (condensing temperature) = 25°C Tevap (evaporator temperature) = -30°C Tsub (subcooling temperature) =10K Dpd (distributer pressure drop) = 2 bar
complimentaryQ (capacity) = 45kW
fsub (subcooling correction factor) = 1.09fp (distribution correction factor) = 0.85
Q = Selected capacity fsub x fp
