2013-03-25. Even if the data centre consists of just one room with a server enclosure – the high power dissipation of current computer hardware can quickly lead to a dangerous build-up of heat. The IT climate control specialist Rittal has a reliable remedy in the form of the flexible and easily installable Liquid Cooling Package Direct Expansion (LCP DX) cooling option.
The correct choice of climate control is very important for the availability of computer hardware. If the so-called "comfort temperature" of the server is not met, shortened service lives or total failure are real threats. In data centres, climate control is a matter of course, though in the small companies that only possess a few servers, the switches and storage systems are faced with a problem. If the devices are housed in a 19" enclosure, the air is usually only circulated by a fan in the ceiling plate or a 19" rack-mounted fan. If the devices are standing around openly in the room, then there is either no climate control or only a usually inefficient room air conditioning system. Rittal has now expanded its product line by adding a flexible climate control option for use in small and medium enterprises. The Rittal Liquid Cooling Package Direct Expansion (LCP DX) can dissipate heat losses of up to 12 kW through an integrated cooling unit, and both its versions are suitable for rack-based and row-based climate control.
Ideal for small and medium-sized installations
The LCP DX fits perfectly into environments where only small and medium-sized IT installations need to be cooled and where climate control with air/water heat exchangers or cold water would be too costly.
It consists of an integrated, speed-controlled compressor, an electronic expansion valve, and other refrigeration components, such as the appropriate external condenser. This is mounted outside the data centre. No active control components are required to operate the external condenser: The speed of the fans is determined only by the pressure of the refrigerant.
In the case of a laterally mounted LCP Rack DX, the cold air can be directed either to the right or to the left in a 19" rack. With series cooling, the LCP Inline DX is mounted between the individual racks and blows the cool air from the front into the cold aisle. They are ideal if the infrastructure is growing and passive air conditioning is no longer sufficient or if it needs to be supported by an active system for reasons of availability. Cold and hot air cannot mix, which contributes to energy efficiency.
The two versions are very quick and easy to install. This allows existing pipelines, for example, from an existing climate control system, to be used for the condenser of the LCP DX. In addition, all the elements of the controls are integrated in the LCP chassis; the condenser itself only has a 230 V power supply for the two built-in fans. Control is only affected by the pressure of the refrigerant. This rules out any additional wiring costs.
Due to the compact and largely pre-assembled design, any certified refrigeration specialist can erect and operate LCP DX systems within a very short period. This is made simpler by in a control unit with an easy-to-read display on the LCP DX, via which the parameters can be set and read. On request, the LCP DX can be integrated in Rittal’s RiZone management system in order to monitor operating parameters and to control the system.
