1 MAKING MODERN LIVING POSSIBLE Technical brochure Thermostatic expansion valves TGE 0, TGE 20 and TGE 40 TGE is a dedicated designed series of thermostatic expansion valves for all standard refrigerants. The hermetic tight design meets the environmental demands for today and future. Versions for no standard refrigerants can be produced to order. Applications Air conditioning systems Heat pumps Water chillers Refrigerated containers Traditional refrigeration systems - and others Features Hermetic TXV for R22, R34a, R404A, R0, R40C, R40A Head pressure independent Version with MOP (Max. Operating Pressure) Straightway flow Balance port (BP) Low hysteresis Max. working pressure 46 bar/ 66 psi Lifetime for heat pump application Cylindrical bulb design with upgraded bulb strap Biflow with expansion in both directions Adjustable superheat setting Laser welded, stainless steel power element / capillary tube Mechanical connections (solder/flare, MIO, ORFS) available Capacity range: 3. to 4 (2.3 to 6 ) R40A Version with or without bleed function DKRCC.PD.AXV.A.02 / 20H499

Protective cap Fig. Balanced port design Adjustable setting Fig. 6 Balanced port design Biflow and adjustable setting The central push pin is fitted with a robust seal (4) that ensures maximum tightness for the life of the valve. Static superheat (SS) can be adjusted by the setting spindle (6), see fig.. The standard superheat setting (SS) is 4K /.2 F and adjustable for 0 8K / F. SS = static superheat OS = opening superheat SH = SS+OS= total superheat Example: Static superheat SS = 4K /.2 F (factory setting) Opening superheat OS = 4K/.2 F The opening superheat is 4K, i.e. from the point the valve begins to open up to nominal. Opening superheat is determined by the design and cannot be changed. Total superheat SH = SS+OS SH = 4+4 = 8K/ 4.4 F Total superheat SH can be altered by changing SS (by using the setting spindle). Balanced port design and advantage The TGE series of thermostatic expansion valves have balanced port design. Balanced port design prevents changes in pressure drop across the valve from influencing Fig. operation and provides excellent control on applications having widely varying operating conditions. Balanced port TXV s are recoended in refrigeration and air conditioning systems with any combinations of these conditions: ) Widely varying head pressures Widely varying evaporator loads 3) Widely varying pressure drop across the TXV 4) Fluctuating or extremely low liquid temperatures ) Intermittent liquid line flash gas DKRCC.PD.AXV.A.02 / 20H499 3

4 Application TGE Fig. 2 is a diagram of a traditional refrigeration plant where TGE is used for flow in one direction only. EVR Fig. 2 Traditional refrigeration plant SGI/SGN DCL/DML Indoor coil TGE 4-way valve SGI/SGN DCB/DMB Outdoor coil TGE Fig. 3 is a conventional split heat pump system shown in cooling mode. This system has two TGE thermostatic expansion valves with fixed direction flow. An NRV check valve is placed in series with each TGE to allow liquid refrigerant to bypass when flow is opposite the TXV fixed direction. NRV Fig. 3 Conventional system with suer/winter operation NRV Indoor coil DCR TGE Fig. 4 Simplified heat pump system Outdoor coil Fig. 4 is a heat pump system similar to that in fig. 3 but with a more compact design, where the distance between evaporator and condenser is very short. This system has only one bi-flow TGE valve metering liquid refrigerant effectively in both directions. 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 TGE is determined by the primary function, i.e. cooling or heating.

12 Sizing 4 TGE p e ~t e Q e EVR SGI/SGN DCL/DML Fig. 8 Sizing examples (SI and US) Refrigerant: R40A Evaporator : Q e = 30 / 8.6 Evaporator with several circuits, i.e. a valve with distributor is required Evaporating temperature: t e = 0 C/ 32 F p e = 8 bar / 6 psi Condensing temperature: t c = +36 C / 96.8 F p c = 22 bar / 39 psi Refrigrant liquid temperature: t l = +26 C / 8.8 F Subcooling: t sub = = 0 K / 96.8 F 8.8 F = 8 F Pressure drop p 2 in the liquid distributor can also be assumed as.0 bar / 4. psi. The correction factor at t sub (fsub) = 0 K /8 F is.09. The correction factor at distributer (fp) = The corrected evaporator thus 30 / 8.6 divided by.09 and 0.96 = 28. /8.2. Since the of the expansion valve must be equal to or slightly higher than the corrected evaporator of 28. / 8.2, a TGE 0 orifice 08 giving 3.3 / 8.9 would be a suitable choice (See tables below).
