THERMOSTATIC EXPANSION VALVES DANFOSS TYPE T2 & TE2 Design

T 2 and TE 2 valves consist of four main components: 1. Thermostatic element 2. Orifice assembly 3. Valve body with connections 4. Superheat setting spindle For a given valve type and refrigerant, the associated orifice is suitable for all versions of the valve body and in all evaporating temperature ranges.

1. 2. 3. 4.

946

Thermostatic element Interchangeable orifice assembly Valve body Superheat adjustment spindle

The valves are equipped with internal or external pressure equalization. Where a liquid distributor is used, always use a valve with external equalization. The double-contact bulb give fast and precise reaction of temperature changes in the evaporator. The bulb design makes mounting quick and easy. The valves are able to withstand the effects that normally occur with hot gas defrosting. To insure long operating life, the valve cone and valve seat are made of steel alloy with particularly good wear qualities.

ELECTRONIC EXPANSION VALVE - PWM DANFOSS AKV 1O Introduction

The Danfoss AKV 10 is an electronic expansion valve designed for commercial refrigeration systems using all types of HFC and HCFC refrigerants. Danfoss can also supply an AKVA 10 version for use with ammonia. The refrigerants for which the AKV 10 is approved are given in the Technical Data section. The AKV 10 functions as an expansion valve and as a solenoid valve.

The AKV 10 valves cover a nominal capacity range from 0.3 to 5.7 tons (R-22). An individual valve is effective over a part of that range depending on which of 8 available orifices is specified. The complete type designation of the valve includes the orifice number, so that a valve with orifice 3 would be designated AKV 10-3.

Availability

AKV 10 valves are supplied complete or as components, as follows: • Complete valve (shipped with coil dismounted from valve)

• Valve without coil • Coil with conduit boss • Spare parts: coil; armature; orifice; filter

Applications

For all evaporators up to a maximum refrigeration capacity of 7 Tons (R-22). Designed for optimal control by Danfoss ADAP-KOOL® system controllers, the AKV 10’s selection of coils make it suitable for use with practically any control system.

Advantages

• Life tested to 50,000,000 cycles

• Wide range of capacities

• Hydraulic damping function minimizes liquid line pulsation

• Easily disassembled

• Normally closed fail-safe design • Use with any fluorinated refrigerant (contact Danfoss for information on AKVA 10 valves for ammonia)

Nominal Capacities

• Orifice and screen are replaceable • When you change refrigerants, simply change the orifice (if necessary).

MOISTURE LIQUID INDICATORS DANFOSS SIGHT GLASSES INTRODUCTION Danfoss sight glasses are designed to accurately indicate the presence of moisture in refrigeration and air-conditioning systems. When system moisture content rises above permissible levels, the “dry/green” indicator will change to yellow indicating a “wet” system. The indication of dangerous moisture levels is essential in helping prevent the formation of harmful acids which are detrimental to the system. Danfoss offers two types of sight glasses: inline and vessel mount. Inline sight glass types SGI and SGN are used in the systems liquid line to indicate both the condition and moisture content of the refrigerant. They incorporate an indicator which changes color dependent on the moisture content. Type SGI is optimized for use with all CFC refrigerants while type SGN is recommended for all HCFC and HFC refrigerants. Vessel sight glass types SGR, SGRI and SGRN are specially designed to be mounted directly on either a receiver or the compressor crankcase to indicate liquid level. Types SGRI and SGRN are available with a refrigerant moisture indicator which can be used with all fluorinated refrigerants. Refrigerant recommendations for the indicator type (I and N) are similar to the inline versions.

P990

FEATURES • Provides fast and easy indication of: - High system moisture content. - Lack of subcooling or low system charge. - Liquid level (vessel mount versions only). • Two indicator types: - Type “I” provides optimal moisture indication for all CFC refrigerants. - Type “N” provides optimal moisture indication for all HCFC and HFC refrigerants. • All indicators are dirt resistant. • Available in both inline and vessel mount versions. • Hermetically sealed, tempered glass for easy viewing. • Available in both flare and solder versions.

MOISTURE LIQUID INDICATORS DANFOSS SIGHT GLASSES SELECTION Prior to selecting a sightglass with moisture indicator, the following should be considered: • Type of refrigerant. • Water solubility of refrigerant. • The level at which a danger signal is required to prevent the formation of harmful acids. The following tables indicate moisture content levels at which the sightglass indicator will register a dry or wet system for various refrigerants. The values under “green /dry” are to be taken as the maximum permissible moisture content for the system. When the green color begins to fade indicating an increase in moisture levels, the sightglass should be checked more frequently. If the moisture levels increase enough to change the indicator to “yellow” indicating a wet system, the filter drier must be changed immediately.

DANFOSS HEAT RECOVERY REGULATORS, HEAD PRESSURE REGULATORS, TYPE KVR, DIFFERENTIAL PRESSURE VALVES, TYPE NRD Consequently, the condenser is partially filled with liquid, so that the effective condensing surface is reduced. In this way the required condensing pressure is restored. Since the real regulation task during winter operation is to keep the receiver pressure at a suitably high value, KVR is combined with a differential pressure valve type NRD, which is sitted in the bypass line shown. NRD begins to open at a differential pressure of 20 psi. When the condensing pressure falls, KVR will begin to throttle. This increases the total pressure drop across the condenser + KVR. When this pressure drop reaches 20 psi, NRD will begin to open thus ensuring that the receiver pressure is maintained. As a rule of thumb, it can be assumed that the pressure in the receiver is equal to the set pressure of the KVR less 14 psi.

P278 P392

Regulator systems KVR + NRD are used to maintain a constant and sufficiently high condensing and receiver pressure in systems with heat recovery or in refrigeration and air conditioning systems with air-cooled condensers.

During summer operation, when the KVR is fully open, the total pressure drop across the condenser and KVR is less than 20 psi. The NRD is therefore closed. To avoid inadvertent opening of the NRD the pressure drop across the condenser at max. load must not exceed 10 psi. If this pressure is exceeded, two NRD units can be used in series instead of one.

During winter operation the ambient temperature falls and with During summer operation the charge can accumulate in the it the condensing pressure of the air-cooled condenser falls. receiver. Therefore the system must be equipped with a sufficiently KVR-regulation is dependent on the inlet pressure. It begins to large receiver to store the excess refrigerant. throttle when the pressure falls below the pressure setting.

EVAPORATOR PRESSURE REGULATORS DANFOSS EVAPORATOR PRESSURE REGULATORS INTRODUCTION KVP evaporator pressure regulators are mounted in the suction line of refrigeration and air conditioning systems. They are used to maintain a constant pressure corresponding to a constant temperature on the evaporator. They also protect against too low an evaporating pressure by throttling down when pressure falls below the set value. They are also used to differentiate the evaporating pressures in two or more evaporators in systems with one compressor.

CHECK VALVES DANFOSS CHECK VALVES INTRODUCTION NRV check valves can be used in liquid, suction and hot gas lines in refrigeration and air conditioning systems using fluorinated refrigerants. They allow flow in only one direction and have a built-in damping piston that makes the valve suitable for installation in lines where pulsation can occur. They are available in both angleway and straightway versions. NRVH check valves can be used in liquid and hot gas lines in refrigeration and air conditioning systems using fluorinated refrigerants. They are supplied with a stronger spring than type NRV (DP = 4.3 psi) and are especially suitable for installation in the discharge line of systems with compressors connected in parallel. PNRV-1

FEATURES • Two Versions available. Type NRV: Requires a minimum ∆p of 0.6 to 1 psi for 100% flow. Type NRVH: Includes a stronger spring that requires a minimum ∆p of 4.3 psi for 100% flow. • Both straightway and angleway versions. • Prevents refrigerant migration from a warm evaporator to a cold evaporator. • Built-in damping piston. Suitable for installation in lines where pulsation can occur, e.g. in the discharge line from the compressor. • Oversize connections provide flexibility in use.

TECHNICAL DATA Refrigerants: CFC, HCFC and HFC Temperature of medium: -60 → +285° F Maximum working pressure: MWP = 400 psig Maximum test pressure: p′ = 520 psig

978

DIMENSIONING AND SELECTION When dimensioning and selecting check valves to be mounted into the compressor discharge line, it is important to be aware of the following: The differential pressure across the check valve must always be higher than the given minimum pressure drop at which the valve is completely open. This also applies to lowest capacity for compressors with capacity regulation, and refrigeration systems that operate at partial load conditions. In refrigeration systems with compressors connected in parallel, it is advantageous to use NRVH equipped with a stronger spring than NRV. With check valve, type NRVH, resonance problems can be avoided at partial load in the refrigeration systems.

SOLENOID VALVES DANFOSS SOLENOID VALVES INTRODUCTION This leaflet presents a newly extended program of Danfoss solenoid valves, type EVR. The program includes a new coil design, type GP, with quick and easy DanlokTM snap down mounting. EVR is a direct or servo operated solenoid valve for liquid, suction, and hot gas lines using fluorinated refrigerants. EVR valves are supplied as separate components; valve body and coil, if required, can be ordered separately.

FEATURES • A complete range of solenoid valves for refrigeration, freezing and air conditioning systems. • Normally closed (NC) and normally open (NO) versions available. • AC and DC coils are interchangeable on all valve body versions. • Use with any fluorinated refrigerant. • Designed for media temperatures up to 220° F. • Flare connections up to 5/8 in. • Solder connections up to 2-1/8 in. • Solder versions have extended connections; there is no need to dismantle the valve when soldering.

Correction Factors for th and te The table values refer to hot gas capacity and are given as a function of condensing temperature tc and pressure drop ∆p across the valve. Capacities are based on a hot gas temperature superheated 40° F above condensing temperature (th = tc + 40° F). For each additional 10° F of superheat above 40° F, the table capacities must be reduced by 1%.

Correction Factors for th and te The table values refer to hot gas capacity and are given as a function of condensing temperature tc and pressure drop ∆p across the valve. Capacities are based on a hot gas temperature superheated 40° F above condensing temperature (th = tc + 40° F). For each additional 10° F of superheat above 40° F, the table capacities must be reduced by 1%. When the valve is used in a hot gas defrost circuit, evaporator temperature affects the capacity. When the evaporator temperature differs from +40° F, adjust the table capacities by multiplying them by the appropriate correction factor found in the following table. te °F Factor
