The HPC–Flex (High Pressure Cooling) system is a multi-functional system for cooling, humidifying, soaking, disinfection, and medication in buildings for any type of livestock production facilities. A correctly dimensioned cooling system will be able to remarkably reduce the temperature in a house for livestock production. On a dry, hot summer day the HPC-Flex cooling system is capable of keeping an indoor temperature as much as 18◦C below the outdoor temperature. The flexibility of the system gives you the opportunity to cool in one, two or more climate zones.
Can be adjusted to all livestock buildings
The HPC-Flex can be adjusted to any given type of livestock building meaning that optimum placement in relation to e.g. ventilation systems is possible. The simple solution, where the system is cooling one climate zone, is a start/stop system that is activated by a climate controller. This system can be installed with one or more strings the length of the building depending on the width of the building and on what kind of ventilation system is installed.
More climate zones
In buildings with more climate zones the demand is cooling individually in each climate zone. Here it is necessary to install a high-pressure valve at the entrance of every climate zone that is connected to a climate controller. Depending on the number of rooms need to be cooled the pump is flow controlled via a frequency inverter attached to the motor.
There is a close correlation between cooling system performance and air flow in the poultry house. The HPC-Flex system from DACS A/S is a multi-functional high pressure cooling system tailored to work with any given ventilation system. The HPC-Flex uses the air flow pattern build by the ventilation system to create efficient evaporation and distribution of the cold air. Under ideal conditions the spraying system is capable of cooling the house to temperatures well below outside temperatures.
Two different applications
The HPC-Flex system is very flexible and can be adapted to any given type of building. The very simple solution where one climate zone (e.g. a large poultry building) needs to be cooled (example 1), or the more sophisticated system where one system supplies 2 - 20 smaller rooms in the same building (example 2).
Example 1 is an on/off system that starts/stops via a climate controller. This system can be adapted to any given type of building, with either one or two lines installed, depending on house width and type of ventilation system installed.
Example 2 is designed to meet the requirements in more complex buildings with more than one room, e.g. a large sow complex with multiple rooms. In a complex like this, each room has specific requirements for cooling which necessitates that each room is installed with a high pressure valve that opens/closes via the climate controller installed in the room.
Since the flow of water through the high pressure pump varies depending on how many rooms the system operates, the pump needs to be speed-controlled via a frequency inverter.
In conjunction with an electronic pressure guard, the frequency inverter ensures a constant pressure on the system of 65 bars. The frequency inverter serves as motor protection for the pump and it is programmed to stop after 10 seconds in the event of a sudden pressure drop caused by e.g. lack of water supply or a line break. The inverter will send an alarm if connected to an alarm system.
