TDE/TDEB is a series of thermostatic expansion valves of the highest technical standards with dedicated design for use in applications such as:– Air conditioning systems,– Heat pumps,– Water chillers,– Refrigerated containers, – Traditional refrigeration systems.

TDE is designed for soldering into hermetic systems and is supplied in straightway versions. The product programme includes standard single port versions (TDE) as well as a balanced port design (TDEB) developed especially for biflow applications. TDE is available for ranges K, AC and N. All versions are available in both industrial and single packs.

This leaflet contains data and code numbers for TDE valves for refrigerants R22 and R407C. TDE valves for R 134a are manufactured to order, and consequently no code numbers are available.

A note on type designation TDE is the standard single port version, TDEB is the biflow balanced port version. The accompanying digit denotes the rated capacity in TR, whereas X denotes R22 refrigeration and Z is used for R407C types. Consequently TDEX 6 is a standard single port valve for R22 with a rated capacity of 6 TR (21 kW), whereas TDEBZ 16 is a biflow balanced port version for R407C with a rated capacity of 16 TR (56 kW).

Biflow operationTDEB with two-way balanced port and universal cross-ambient charge is designed for biflow operation. With flow in the opposite direction, the rated capacity is reduced by 15%. TDE types with MOP charges cannot be used for biflow operation.

To avoid charge migration when MOP valves are used, the bulb temperature must be lower than the thermostatic element temperature.

Application

Fig. 2. Traditional refrigeration plant

Fig. 3. Conventional system with summer/winter operation

Fig. 2 is a diagram of a traditional refrigeration plant where TDE is used for flow in one direction only.Fig. 3 is a conventional split air conditioning/heat pump system with cooling/heating operation and two expansion valves with fixed direction of flow.The system is shown in a cooling mode.The system shown requires two thermostatic expansion valves, e.g. TDE, and two NRV check valves. SGI/SGN is placed in the liquid line before TDE, in this case with cooling as primary function. Changeover between cooling and heating is performed via a 4-way solenoid valve.

Fig. 4. Simplified unit with summer/winter operation

Fig. 4 is similar to the previous system but as a compact unit with a short distance between evaporator and condenser. This system is also shown in a cooling condition.The two expansion valves have been replaced by one TDEB biflow valve. Check valves are not required.Changeover is by means of a 4-way valve.A suction filter drier is often placed in suction lines just before the compressor.The normal flow direction of TDEB is determined by the primary function, i.e. cooling or heating.

Design and function

Fig. 5 Single port design (TDE)

TDE is designed with straight through solder connections, fixed orifice and thermostatic element. Two push pins in non-friction stuffing boxes connect the power assembly with the orifice.The thermostatic element characteristics is designed to nominal capacity at less than 4K opening superheat in accordance with ANSI/ARI 750-87. The standard factory setting is 4K, so the operating or total measurable superheat is 8K as capacity table values.

Port designThe TDE series of thermostatic expansion valves features two different orifice designs: single port and balanced port. TDE 3 - 7.5 are designed with single port.TDE 8 - 19 is available in both single port versions (TDE) and balanced port versions (TDEB). TDE 20 - 40 is designed with balanced port.

Port design and applicationThe choice between single or balanced port is based on an assessment of the power balance of the application. The power balance is expressed as static superheat variation as a function of the condensing pressure or pressure drop across the orifice. For the TDE 8 - 19, where both single port and balanced port versions are available, the right selection for your application is based on the diagram in figure 7/8, which shows the variations in superheat as a function of the condensing pressure. If TDE 8 - 19 is to be used for applications with two-way power balance (e.g. biflow applications) the balanced port versions must be used.

Static Superheat variation (fig. 7/8)The factory setting of 4 K static superheat (SS) is made at 17.5 bar (abs.) – corresponding to 45°C condensing temperature. Consequently the superheat setting variation is 0 at 17.5 bar, as appears from the diagrams in fig. 7 and 8. In normal flow direction the condensing pressure operates in the opening direction, and consequently SS decreases at values above 17.5 bar and increases at values below 17.5 bar. In biflow condition and with opposite flow direction

Fig. 9

Fig. 8Static superheat variation, TDEB 8 - 19 (balanced port design)

Normal flow

the situation is reversed. When compared with normal flow direction the SS variation is twice the size. The static superheat is adjustable, and as such it can be adapted to the given condensing pressure to match the factory setting.

Terminology (fig. 9)SS = static superheatOS = opening superheatSH = SS + OS = total superheat

Example:SS = 4 KStatic superheat SS is factory set at 4 K.

OS = 4 KOpening superheat is 4 K from the beginning opening to the opening that gives the table capacity. (Nominal capacity).The opening superheat is determined by the construction and cannot be changed.

SH = SS + OS = 4 + 4 = 8 KTotal superheat SH can be changed by changing SS (by using the setting spindle).

Sizing

Sizing exampleRefrigerant R22Evaporator capacity Q

e = 20 kW

Evaporator with several sections, i.e. a valve with distributor is requiredEvaporating temperature t

e = 0°C

pe = 4 bar

Condensing temperature tc = +36°C

pc = 13 bar

Refrigrant liquid temperature tl = +26°C

Subcooling ∆tsub = 36–26 = 10 K

From the data supplied determine pressure drop ∆p in TDE.Pressure drop ∆p

1 in liquid lines, pipe bends,

filter, sight glass, solenoid valve, etc. can be assumed to be 0.5 bar.Pressure drop ∆p

2 in the liquid distributor can

also be assumed as 0.5 bar.

From the diagram it can be seen that evaporating pressure p

e is equal to

pc–∆p–∆p

1–∆p

2.

Thus, pressure drop ∆p in TDE equals p

c–p

e–∆p

1–∆p

2 = 13–4–0.5–0.5 = 8 bar.

Pressure drop in risers, etc. is not taken into account.

The correction factor at ∆tsub

= 10 K is 1.07.The corrected evaporator capacity thus becomes 20 divided by 1.07 = 18.7 kW

Since the capacity of the expansion valve must be equal to or slightly higher than the corrected evaporator capacity of 18.7 kW, a TDEX 6 giving 20.1 kW would be a suitable choice (See example below).
