Introduction 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 prograe 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 R7C. TDE valves for R34a 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 in, whereas X denotes R22 refrigeration and Z is used for R7C types. Consequently TDEX 6 is a standard single port valve for R22 with a rated of 6 (2 kw, whereas TDEBZ 6 is a biflow balanced port version for R7C with a rated of 6 (56 kw. Features Versions with two-way balanced port Head pressure independent Versions for biflow application (excl. valves with MOP Refrigerants: R22, R7C TDE for R34a manufactured to order.

Simplified unit with suer/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 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 The two expansion valves have been replaced by one TDEB biflow valve.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.

Two push pins in non-friction stuffing boxes connect the power assembly with the orifice. The thermostatic element characteristics is designed to nominal at less than 4K opening superheat in accordance with ANSI/ARI 7-87. The standard factory setting is 4K, so the operating or total measurable superheat is 8K as table values. Port design The 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 8-9 is available in both single port versions (TDE and balanced port versions (TDEB. TDE - is designed with balanced port. Normal: A B Reverse: B A Fig. 6 Biflow balanced port design (TDEB Port design and application The 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 8-9, 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 8-9 is to be used for applications with two-way power balance (e.g. biflow applications the balanced port versions must be used.

Fig. 8 Static superheat variation, TDEB 8-9 (balanced port design Normal flow Static Superheat Variation [K] TDEBX 9 TDEBX 8-6 Condenser Pressure [bar] Static Superheat variation (fig. 7/8 The factory setting of 4 K static superheat (SS is made at 7.5 bar (abs. corresponding to 45 C condensing temperature. Consequently the superheat setting variation is 0 at 7.5 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 7.5 bar and increases at values below 7.5 bar. In biflow condition and with opposite flow direction 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 superheat OS = opening superheat SH = SS + OS = total superheat Example: SS = 4 K Static superheat SS is factory set at 4 K. OS = 4 K Opening superheat is 4 K from the beginning opening to the opening that gives the table. (Nominal. The opening superheat is determined by the construction and cannot be changed. SH = SS + OS = 4 + 4 = 8 K Total superheat SH can be changed by changing SS (by using the setting spindle. Fig. 9 DKRCC.PD.AM0.A3.02 / 5H4608 7
