Data Sheet
Float valve Type HFI
Robust and reliable solution for high pressure control
HFI is a high pressure oat valve with internal liquid measuring device. The oat valve is designed for direct ange mounting or welding on to plate heat exchanger type condensers, as illustrated in Figure 1: Plate heat exchanger
HFI is direct acting, therefore no dierential pressure is required to activate the valve.
HFI is robust and reliable due to its simple design. The oat valve is equipped with a purge valve for purging non condensable gases e.g. air from the top of the valve housing. This feature is also useful if the valve has to be serviced.
The HFI is available with two external connections on the housing for drainage and pressure equalizations.

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.

The principle of high pressure control
Introduction
In installations with one application high pressure control is an eective and cost saving way of expanding liquid from the condenser to the low pressure side.
High pressure refrigerant entering the condenser will start to condense, consequently condensate will accumulate at the bottom of the condenser and in the oat valve.
When capacity demands increase, the liquid level in the oat valve will rise, which will cause the valve to open and the refrigerant to expand into the separator at the low pressure side.
When the valve is closed, there will still be a small by-pass over the seat, so any remaining liquid will equalize slowly to the low pressure side, for instance during an o cycle. Therefore the system will equalize automatically and the compressor can start up without excessive back pressure. The size of the bypass is predetermined and dened by geometry of the elements.
It follows from the above, that almost all the refrigerant will be accumulated on the low pressure side under normal conditions. Therefore under normal conditions no high pressure receiver is necessary when using the HFI for high pressure control.

Computation and selection
In R 717 plants (ammonia) On the following pages you will nd tables with capacities of the oat valve at various operating conditions.
Select a valve using the specic operating conditions. The chosen valve must have a capacity higher than the required capacity during nominal operation, as well as during plant start up.
In plants using other refrigerants than ammonia The capacity of the oat valve can be calculated by using the values and the equation to the right. However, the density of the refrigerant must be in the range: 500 to 700 kg/m3.
For densities outside this range please contact your local Danfoss Sales Company.
