Thermostatic expansion valves for ammonia Type TEA
Regulate and monitor ammonia and uorinated refrigerants in industrial refrigeration systems
Thermostatic expansion valves regulate the injection of refrigerant liquid into evaporators. Injection is controlled by the refrigerant superheat.
Therefore the valves are especially suitable for liquid injection in „dry“ evaporators where the superheat at the evaporator outlet follows the evaporator load proportionally.
• Large temperature range: -50 °C – +30 °C Can be used in both freezing and refrigeration systems
• Interchangeable orice assemblies
• Interchangeable thermostatic element
• Rated capacities from 3.5 – 295 kW, 1 – 85 tons (TR)
• External superheat setting Can be matched to all evaporators to give optimum evaporator utilization
• Patented double contact bulb Fast and easy to install. Good temperature transfer from tube to bulb
• Classication: DNV, CRN, BV, EAC etc. To get an updated list of certication on the products please contact your local Danfoss Sales Company

Thermostatic expansion valves for ammonia, Type TEA
Functions
TEA is equipped with interchangeable orice assembly and thermostatic element. TEA is built up of three interchangeable main components:
• Thermostatic element (1)
• Orice assembly (2)
• Valve body (3), with ange connections
The valve has external equalization. A separate outlet orice assembly (10) is for use with TEA 20-1 (3.5 kW) only.
The double contact bulb gives fast and precise reaction to temperature changes in the evaporator suction line, even with much reduced evaporator load. It also makes tting the bulb quick and easy. The valves are able to withstand the eects that normally occur with hot gas defrosting.
The movement of the setting spindle is transferred by a gearwheel mechanism that ensures smooth superheat setting. The throttling section of the orice assembly has a long operating life, the valve cone and seat being made of a special alloy steel with particularly good wear qualities.
NOTE:
The TEA is not able to close completely tight. Consequently a solenoid valve is needed to shut o liquid supply when systems stops.

Refrigerants
Refrigerant R717 - NH3(Ammonia)
New refrigerants
Danfoss products are continually evaluated for use with new refrigerants depending on market requirements.
When a refrigerant is approved for use by Danfoss, it is added to the relevant portfolio, and the R number of the refrigerant (e.g. R513A) will be added to the technical data of the code number. Therefore, products for specic refrigerants are best checked at store.danfoss.com/en/, or by contacting your local Danfoss representative.

Description
Values
Evaporator capacity Q
e
265 kW (75.3 TR)
Evaporating temperature t
e
-20 °C (~pe = 1.9 bar)
Condensing temperature t
c
+32 °C (~pc = 12.4 bar)
Subcooling Δt
4K
Thermostatic expansion valves for ammonia, Type TEA
NOTE:
Subcooling ∆t = 4K ahead of the valve.
Example
Table 6: Temperature and cooling data
If the pressure drop Δp1 across pipelines, etc. is calculated, for example, as 0.5 bar, the eective pressure drop across the thermostatic valve becomes Δp = pc − pe − p1 Δp = 12.4 − 1.9 − 0.5 = 10 bar. Now, from the capacity table at an evaporating temperature te = -20 °C and Δp = 10 bar, the capacity is 267 kW.
The column on the far left of this point gives the valve designation: TEA 85-85.
The ordering table gives the code no. for TEA 85-85: 068G6009.
Generally, the maximum capacity of a valve is approx. 20% higher than the value given in the table.
If a dierent capacity is subsequently required, a separate orice assembly with a suitable rated capacity can be ordered to replace the one tted in the installed valve.
