Hot gas powered on/oﬀ valve Type ICSX

For HFC/HCFC hot gas defrost application

ICSX hot gas powered on/o valve belongs to the ICV (Industrial Control Valve) family but it is dedicated designed for HFC/HCFC systems.

ICSX hot gas powered on/o valve is to be used in wet and dry suction lines and in liquid lines without phase change(i.e. where no expansion takes place in the valve) providing ON/OFF function in large refrigeration systems.

The valve comprises four components: valve body, function module, top cover and external pilot connection. However, only function module is with dedicated design, valve body, top cover(with one pilot pressure connection) and external pilot connection are exactly the same as standard pilot operated servo valve ICS.

One NC(normally closed) and one NO(normally open) solenoid valves with one power supply signal are needed to control the ICSX hot gas powered on/o valve. For safety purpose, it is strongly recommended to install an additional NC solenoid valve in parallel.

Figure 2: ICSX hot gas powered on/o valve

The function module of ICSX hot gas powered on/o valve is with a minor design change on current function module of ICS pilot operated servo valve. The equalization hole in the piston is removed, see Figure 2. However, the top cover and housing are remain the same as current ICS pilot operated serve valve.



NOTE:

There is a risk of trapped cold liquid in the volume above the piston (marked red on Figure 2) and the external pilot connection and system pipes.

ICSX is a pilot controlled valve used as a open/close valve in suction lines to open with external pressure. This means that the valve can operate with no internal pressure dierential (Pd) at all and provide a low pressure loss over the valve.

Low Pd is the key objective and makes the ICSX ideal for applications that are sensitive to dierential pressure loss. Though Pd is kept low, it can still be quantied, and must be considered when choosing valve size. Check in the Coolselector, select "ICS external" from the "Product Families".

To assure a proper opening of the valve, the hot gas inlet pressure must be higher than 0,5 bar above the inlet pressure of the ICSX.

Hot gas powered on/o valve, type ICSX

See Figure 3 and See Figure 4 above, two additional solenoid valves are needed to control the ICSX, pos.1(NC) and pos.2(NO) with one power supply signal. The external pilot pressure line must be connected to a system pressure (p2), and usage of NC and NO solenoid valves ensures that trapped liquid (condensed refrigerant) cannot build up excessive hydraulic pressure due to pressure relief through the NO solenoid valve. Please consider the MOPD of the solenoid valves.

ICSX hot gas powered on/o valve is kept open when power is applied to the coils of solenoid valves pos. 1 and pos.

2. It is closing and kept closed when the coils of solenoid valves pos. 1 and pos. 2 are de-energized.

It is strongly recommended to install an additional NC solenoid valve pos.3 in parallel for safety purpose so that soft opening and also high pressure after defrosting is decreased softly. The open period for solenoid valve pos.3 to drain the high pressure from evaporator has to be determined by commissioning. The opening of ICSX main valve might not be done before high pressure of evaporator be drained.

The manual spindle can be used to open the valve. Be aware of, that it might not be 100% opening. Depending on valve size.

NOTE:



The use of stop valves in the pilot lines need to be assessed by a risk assessment according trapped cold liquid. This risk assessment must be carried out by the designer of the plant.

If other automatic controls are used for controlling the hot gas power or other systems to control the hot gas power, a risk assessment according trapped liquid as mentioned above must be carried out by the designer of the plant.

Due to the design of the standard valve as a servo operating main valve controlled by dierential pressure, the emptying of the volume over the piston (Marked red on Figure 2) might take longer than e.g. an ICLX valve. It might take several minutes when the volume is lled with condensed refrigerant. This must be considered when designing the defrost sequence, especially in the delay time for opening the hot gas line.

Hot gas powered on/o valve, type ICSX

Application

Typical applications for large refrigeration systems with HFC/HCFC refrigerant, both pump and DX hot gas defrost application.

Figure 5: ICSX Functional diagram

NOTE:

*Choose ICS+EVRST in EKE 400 and the NC and NO solenoid valves should be connected together.

Product specication

Design

ICSX hot gas powered on/o valve uses the same top cover with 1 pilot and housing as the standard ICS, but with dedicated function modules.

ICSX hot gas powered on/o valve is no longer a standard pilot driven main valve, the one pilot hole has to be connected to the system pipe by external pilot connection, see Ordering from the parts program.

Valve body and top cover material is in low temperature steel.

The external surface is zinc-chromated.

For the storage, transport and installation, the external surface of the valve housing must be protected against corrosion with a suitable top coating after installation involving welding and consequent assembly.

Protection of the ID plate when painting the valve is recommended.

Refrigerant

Applicable to HCFC, HFC refrigerants.

Use with ammable hydrocarbons cannot be recommended; please contact Danfoss.
