Thermostatic expansion valves, type TE5 to TE55

Transcription

1 Thermostatic expansion valves, TE5 to TE55 Introduction The TE series expansion valve regulate the injection of refrigerant into evaporators. It controls the refrigerant flow based on the superheat. The exchangeable power element is produced with the well known Danfoss laser welding technology for extended lifetime capability. The TE series is available with a wide range of orifices which will cover a wide range of applications. Features and benefits Featurs Large operating range: N-range -40 C to +0 C / B-range -60 C to -25 C Interchangeable orifice assembly. Stainless steel power element, capillary tube and bulb. Wide capacity range. MOP function is available. Superior charge performance. Patented bulb strap design. MWP (maximum working pressure) 28 bar. Wide capacity range to minimize capacity gap and overlap. TE55 has balanced orifice design. Benefits Equally applicable to freezing, refrigeration and air conditioning plant. High flexibility for reduced stock and easy capacity matching. High corrosion, strength and vibration resistance. Capacity from 0.5 ~ 245 kw (3~ 70 TR) (AHRI standard, 4K OSH). MOP charges protect the compressor motor against excessive evaporating pressure. Improve system reliability. Improve reaction and installation time. Fast installation and bulb self aligning. Better surface contact with tube and heat transferring character. Higher application pressure range. Easy to select. Reduce negative impact from condensing temperature variations.

Operating Pressure Superheat 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 setting spindle. The standard factory superheat setting 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. Example Static superheat SS = 4 K Opening superheat OS = 4 K Total superheat SH = = 8 K Using orifice with range B element, please check superheat under running conditions and readjust superheat setting, if necessary. Identification 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 = R22 N = R34a S = R404A/R507 Z = R407C The label holds information like valve, evaporating temperature range, MOP point, refrigerant, and max. test pressure, PS. Element label assembly for TE5, TE2, 20 and 55 The orifice assembly is marked on top of the spring cup, e.g. as shown in the figure. For a given size of valve, the same orifice assembly can be used for valves with ranges N and B. TE2 = For valve 05 = no. 067B2708 = code no. for sales order 009 = Production date (Week, Year) assembly marking for TE5 to TE55 Capillary tube tag for TE5 to TE55 The label gives the orifice size (04). A new label always accompanies a new orifice assembly. Capillary tube tag TE5 to TE55 2 DKRCC.PD.AB0.A3.02 / 520H5227 Danfoss A/S (AC-SMC / sw), 03-20

3 Thermostatic expansion valves, TE5 - TE55 Design/Function General All TE valves have an interchangeable orifice assembly. TE5 to TE55 valves are built up of three main components: - Thermostatic element 2 - assembly 3 - 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 seat are made of a special alloy with particularly good wear properties.
